Gateway vs Router: What’s the Difference?

When it comes to the difference between gateway vs router, many people who are unfamiliar with gateway and router may be confused. So it’s necessary to clarify the differences between them. To help you get a general idea about the differences between gateway and router, this article will focus on what is a gateway, what is a router, gateway vs router: what’s the difference, and when to choose which.

What Is a Gateway?

As is suggested by its name, a gateway is a network entity and also called the protocol converter. It can connect a computer of one network to another and define the boundaries of a network. If two networks of different protocols want to connect with each other, both networks need to have gateways which provide exist and entry points for computers from the two networks to communicate. In another word, a gateway can join dissimilar systems.

Gateway vs router: How a gateway works as a protocol converter

Figure1: How a gateway works as a protocol converter

What Is a Router?

As a network layer device, a router connects multiple networks together and controls the data traffic between them. People who are new to router often muddle it with network switch, which is a high-speed device that receives incoming data packets and redirects them to their destination on a LAN. Based on internal routing tables, a network router reads each incoming packet’s IP address and its destination IP address, then decides the shortest possible path to forward it. What is a routing table? A routing table contains a list of IP addresses that a router can connect to transfer data. Besides, routers usually connect WANs and LANs together and have a dynamically updating routing table. Gigabit Ethernet switches and hubs can be connected to a router with multiple PC ports to expand a LAN. Not only that, a router divides broadcast domains of hosts connected through it.

Gateway vs router: How a router works in wired and wireless connections

Figure2: How a router works in wired and wireless connections

Gateway vs Router: What’s the Difference?

What are the differences between gateway and router? The following chart will differentiate them from 7 different aspects.

Network Equipment

differentiating what is inside network and what is outside network

Gateway vs Router: When to Choose Which?

To choose between gateway vs router, you need to consider the requirement of your network.

Connection In One Network With Router

For example, there are 30 computers connected inside Network A. All these computers communicate with each other. In this situation, no gateway is needed. Because a router with a routing table that defines the hops within those 30 computers is enough.

Connection Between Different Networks With Gateway

In another hand, we suppose that there are two networks, that are Network A and Network B. Computer X from Network A wants to send data to Computer Y from Network B, then there need to have both a Gateway A and a Gateway B so that the two networks will be able to communicate.

Summary

Gateway vs router is detailedly explained in the above passage from the aspects of primary function, supporting feature, support of dynamic routing, working principle, etc. Briefly speaking, a gateway is a single point of access to computers outside your network like a door, while a router determines the shortest possible path your data can travel from Computer A to Computer B, like a hallway or a staircase. All in all, it is important to consider both your current and potential future needs when assessing what option to use between gateway vs router.

What Is DWDM?

The Internet demand is always growing, especially the hugely popular video streaming services are increasing greatly. This provides a threat for the service provider. As the hottest topic in the telecommunication industry, DWDM offers unprecedented bandwidth which promises an effective solution to the challenges posted by the Internet growth. But what is DWDM, do you really know?

What Is DWDM?

DWDM wiki has defined it as an optical multiplexing technology. As one wavelength pattern of WDM system (the other pattern is CWDM), it stands for Dense Wavelength Division Multiplexing, which is used to increase bandwidth over existing fibre networks. This powerful technology can create multiple virtual optical fibres, so as to increase bandwidth on existing fibre optic backbones. It means that the fibre in DWDM system can transmit multiple signals of different wavelengths simultaneously. More specifically, the incoming signals are assigned to specific wavelengths within a designated frequency band, then the signals are multiplexed to one fibre. In addition, the most commonly used grid is the 100GHz grid, which consists of a spacing of 0.8nm per channel.

After knowing what is DWDM, we need to learn DWDM architecture. A typical DWDM architecture includes transmitter, receiver, optical amplifier, transponder, DWDM multiplexer and demultiplexer. Transmitter and receiver are the place where the source signal comes in and then multiplexed. Optical amplifier can amplify the signals in the wavelength range, which is very important for DWDM application. Transponder is the converter of wavelength. It’s responsible for converting the client optical signal back to an electrical signal. Multiplexer first combine multiple wavelengths of different fibre to one fibre, and at the receiving end, the demultiplexer separates all wavelengths of the composite signal onto individual fibres. Commonly, channels of DWDM Mux/Demux are available in 8, 16, 40 and 96 channels. All the DWDM basics work together to enable high capacity data flow in ultra-long distance transmission. The following figure is DWDM working principle.

what is DWDM

Why Use DWDM Technology?

The most obvious advantage of DWDM technology is providing the infinite transmission capacity, which would meet the increasing Internet demand. And more capacity can be added just by upgrading several equipment or increasing the number of lambdas on the optical fibre. Thus, the investment of DWDM technology has been reduced. Besides, DWDM technology also enjoys several other advantages, like the transparency and scalability.

Transparency. Due to DWDM is a physical layer architecture, it can support Time Division Multiplex and data formats like Gigabit Ethernet, Fibre Channel with open interfaces over a physical layer.

Scalability. It’s easy to be expanded. A single fibre can be divided into many channels, thus there is no need to add extra fibre but the wavelength will be increased. All these advantages make DWDM popular in the network.

Application of DWDM

As a new technology more applications of DWDM are yet to be tapped and explored. It was first deployed on long-haul routes. And now, DWDM technology is ready for long distance telecommunication operators. Using point to point or ring topology, the capacity will be dramatically improved without deploying an extra fibre. In the future, DWDM will continue to provide a higher bandwidth for the mass of data. With the development of technology, the system capacity will grow.

Conclusion

As for the question what is DWDM, I believe you have a good understanding of it. This powerful technology is related closely with current industry advancements trend. Now, service providers are faced with the sharp growth in demand for network capacity, DWDM is the best solution. With DWDM technology, the transmission work is no longer limited by the speed of available equipment, because it provides the high bandwidth without limit. We believe, DWDM will shine in the network world.

Best Way to Set Up Ethernet Switch and Mesh Network

Want to connect all your wired and wireless devices and expand your network with ease? Setting up an Ethernet switch and mesh network may be the best way. Because today it becomes increasingly difficult to use only a router to make your all connections since the approach of IoT. However, Ethernet switch and mesh network will function adequately no matter how many connections you want to make. Here focus on the Ethernet switch and mesh networking.

Why Mesh Networking?

Unlike the stand-alone routers, which will arise signal loss or strength drops when you go away from them, while mesh Wifi networks can use another connection to create a continuous wireless link which minimises the possibility of dead zones. For example, you put your router in the downstairs living room. When you are on the first floor, your phone can connect to the Internet with a strong signal. But when you want to search the Internet in the upstairs office, the signal would degrade. Of course, you can boost a Wifi router’s connection with a signal amplifier. But in that situation, you have to manually connect your phone to the amplifier’s Wifi network. And if you go back to the downstairs, you have to switch back to the main router’s wireless network again. What a pain! Luckily, working with mesh Wifi networks, things are different. In a wireless network, all the nodes are connected with each other which means any node could be an Access Point (AP). Therefore, through the APs, wireless mesh network allows your phone automatically connects to the strongest signal no matter you are in the upstairs or downstairs. That’s better than what we could do with the traditional router Wifi networks.

mesh network_

Figure 1: Mesh network exists in our life.

When to Set Up Ethernet Switch and Mesh Network

If you want to build a wireless mesh network, using an Ethernet switch is a good choice. Before installation, you should consider how much coverage you need in your home. For many people, the money might be better spent on a Wifi router with good quality, since the mesh network equipment like the switches cost too much. But if you want to cover a large area with signal and your home brick is too solid for signal travel through, then use a switch to build wireless mesh network is a way to go.

Use FS Ethernet Switch to Build Mesh Network

Achieving a cheap mesh network is based on switches. FS.COM publishes a set of Gigabit Ethernet switch supporting 1G, 10G, 40G and 100G Ethernet, in order to meet different demands. All the Ethernet switches meet all design and safety standards made by international and industrial organizations like ISO9001, FCC etc.

The following is a 10Gb switch named S5800-48F4S. It has 48 1GbE SFP ports and 4 10GbE SFP+ ports. This switch is a Layer2/3 switch with low latency of 2.3us. With the switching capacity, it provides a throughput of 130.95MB. Besides, it supports functions like MLAG, SNMP and so, making it becomes popular on market. Following the S5800-48F4S switch installation guide, you can easily finish the switch installation. Then you can configure the bridge parametres of AP according to the installation instructions to build a mesh network.

48 port Ethernet switch

Figure 2: S5800-48F4S 48 Port Ethernet Switch

Conclusion

Due to mesh network advantages and disadvantages, we understand why and when to use wireless mesh network. Based on Ethernet switch, mesh networking can spread out fast Wifi across a relatively large area, which makes our life and work more efficiently. So don’t hesitate, pick one Ethernet switch from FS.COM to optimise your Wifi network.

VPLS vs VPWS—How Much Do You Know?

Recently, network virtualisation technology is the most popular and advanced technology both in our daily life and professional fields. There is a wide range of VPN technology available, such as VPLS and VPWS. Based on the use of Ethernet transport, VPLS and VPWS provide high-speed communications. But many business users who are seeking the most cost-efficient and efficient solutions for their network are confused when they face the two technologies VPLS and VPWS. Here focus on VPLS vs VPWS, to unveil their mysteries.

What Is VPLS

Virtual private LAN service (VPLS) is a Layer 2 technology that uses MPLS and VPN to connect different LANs over the Internet. It’s a point to multipoint service that enables geographically isolated sites to be connected through a MAN or a WAN. And all services in a VPLS are on the same LAN. CE and PE are the two basic concepts used in VPLS. CE stands for custom edge, which is the device like a router or a 10gbe switch at the customer premises. PE, the provider edge, is defined as the router at the network of the service provider. It’s typically connected with the CE and responsible for VPN access.

How VPLS Works?

Now let’s look at how VPLS works. In VPLS, first, the packet from a service provider network is sent to a CE device (for example, a 48 port 10gbe switch ). Then, the packet is sent to a PE router. It goes through the service provider network via the MPLS label-switched path. At last, when the packet arrives at the exist PE router, it will forward the traffic to the CE device at the destination customer site. For people who implement VPLS on a data switch, they will enjoy a fast, secure and homogeneous network with lower latency.

VPLS of VPLS vs VPWS

Figure 1: Example of VPLS

What Is VPWS?

Virtual private wire service or VPWS is built on MPLS network and provides point to point connections that connect end customer sites in a VPN. It’s also a Layer 2 technology that consists of three main elements, PE routers, Label Distribution Protocol (LDP) and Label Switched Path Tunnel. Unlike the traditional VPNs over Layer 2 circuits, which needs extra separate networks for IP and VPN services, VPWS can share the provider’s core network infrastructure between IP and Layer 2 VPN services. Thus, the cost of these services will be reduced. In addition, a VPWS Layer 2 VPN can be a full mesh or a hub and spoke topology. And MPLS is the tunneling in the core network. But other tunneling protocols like GRE also can be used in VPWS.

VPWS

Figure 2: Example of VPWS

VPLS vs VPWS: What Are the Differences?

From the above, we can see clearly that the biggest difference of VPLS vs VPWS is that the VPLS provides a point to multipoint servers, while the VPWS provides a point to point service. It means that the CE devices of VPLS and VPWS are different. For VPLS, the CE routers just send all traffic to the PE devices. In contrast, in VPWS, CE routers are used to carry out Layer 2 switching and have to decide which virtual wire could be used to send data to another customer site.

Conclusion

As regard with VPLS vs VPWS, we know they both can build a Layer 2 VPN service to meet today’s high speed network requirement. So don’t be hesitated, use your data switches or routers to set up a safety and efficient VPLS or VPWS service to optimise your network.

What Is DHCP and How It Works

To transmit data back and forth across the Internet, an IP address that administrators have to accomplish and configure on a router or Lay3 fibre switch is the essential cornerstone of a host. Besides, when you want to communicate with other networks, you need to know the default gateway address and subnet mask for the local network, as well as the DNS server. DHCP can help you get all the information dynamically. So what is DHCP and how it works?

What Is DHCP?

DHCP wiki defines the term dynamic host configuration protocol as a network management protocol used on UDP/IP networks. It assigns an IP address and some other configuration parameters to each network device automatically, so that the device will be authorized to communicate with other IP networks. This means users don’t need to configure the network, just plug the wire into your computer or connect to the WiFi, your computer will automatically receive the IP address, subnet mask, default gateway and DNS server. Then how to enable DHCP? DHCP can be installed on a single server or integrated in most network equipment like a Gigabit PoE switch, a router or even the firewall. The following are some related terms we should know.

  • DHCP Client—It obtains an IP address and other parameters from a DHCP server. It is the initiator of an IP address allocation.

  • DHCP Server—It assigns IP address and other parameters to the DHCP client.

  • DHCP Repeater—It forwards DHCP messages between a DHCP server and DHCP clients.

  • DHCP Snooping—It records the users’information that has applied for IP address through the layer 2 equipment.

What Are the Advantages of DHCP?

DHCP protocol reduces the complexity and numbers of administrative work by using automatic TCP/IP configuration. This is the greatest benefit. Today, no matter in the data centre or at home, more and more devices are being networked from printers and fax machines to TV and fridges. Often times, these devices are placed in different locations, without DHCP, you have to get up out of your comfy chair and find the device and configure each manually. But assisted by DHCP protocol, all you need to do is changing the settings on the server or may be a 10gbe switch. As addresses are assigned automatically, there is no need to keep a record of the used and free ones. Besides, DHCP snooping can detect unauthorized DHCP server on the network.

How DHCP Works?

As the title mentions what is DHCP and how it works, now we have learned what DHCP is, let’s turn to its operation. In essence, DHCP leases IP address and other parameters to the specific clients for a period of time. The following picture shows how DHCP works.

What Is DHCP and How It Works

Step one: When a new client wants to join a network, it will broadcast a DHCP discover packet to the servers.

Step two: To answer the request, DHCP servers will send the free DHCP offer packet to the client.

Step three: The client takes the first DHCP offer message from different serves. Then it will send a DHCP request to the Internet to indicate which IP address it has taken.

Step four: DHCP server sends an acknowledge message to make sure the IP address has been used that will not assign to any other client. And now the client can participate on the network.

Conclusion

With regard to the question, what is DHCP and how it works, I think you have found the answer. Any questions of DHCP or network switch supporting DHCP, you can visit FS.COM or contact via sales@fs.com.

What Is IGMP Snooping

With the development of Internet technology, traditional network unicast mode can’t meet today’s data transmission requirement. On the contrary, this mode increases network load and consuming network bandwidth greatly. IGMP snooping is developed to solve the problem. So what is IGMP snooping?

Introduction of IGMP Snooping

IGMP (Internet Group Management Protocol) is a communications protocol. So what is IGMP used for? Commonly, it’s used to establish membership in a multicast group. And each member host of an IP multicast is a transmitter or receiver.

As for IGMP snooping, which sounds like an obscure hacker technique that may break into one’s network, is actually an advanced option available on most switches or routers. Wiki defines it as the process of listening to IGMP network traffic. It is a multicast constraint mechanism running on the two-layer device, which is used to manage and control the multicast group. If there are plenty of multicast traffic in your network, the whole performance may be affected due to the excessive false flooding. At this moment, the IGMP snooping switch can help to optimize your network. It enables the Gigabit Ethernet switch configured with IGMP snooping decides which devices will receive the applicable multicast traffic, thus the others won’t receive the message. This means the broadcast packet on layer 2 has been reduced so that the network bandwidth will be conserved. Besides, IGMP snooping helps improve message information.

IGMP Snooping Process

After knowing what is IGMP snooping, let’s see how it works. Once a device joined the multicast group, the router or fiber switch will notice this. Then the message cab forwarded to the devices that have joined the multicast group. Look at Figure 1, when the switch runs without IGMP snooping, the multicast packet will be transmitted to host A, B, and C. But when the switch has set up IGMP snooping, only multicast group members host A and C can receive the multicast packet. This is the main IGMP snooping tutorial.

What Is IGMP Snooping

Figure 1: The picture shows how IGMP works.

Using FS.COM Switch to Build IGMP Snooping 

To keep pace with technology development, FS.COM releases a set of switches to help customers establish IGMP snooping. Here is a 24 port switch named S3900-24T4S. The fanless 24-port 10/100/1000BASE-T Gigabit stackable managed switch provides an affordable solution for business of all sizes requiring switches with essential L2 switching features like VLAN and IGMP snooping, along with a simple and intuitive management interface.

Conclusion

Now I think you know the answer to the question we posed at first, what is IGMP snooping. When IGMP snooping is enabled, the bandwidth consumption will be reduced in a multi-access LAN environment so as to avoid flooding the entire VLAN.

How to Use a PoE Injector to Install an IP Camera?

Are you looking for a solution to easily power your IP cameras? It’s no doubt to use a PoE injector or Gigabit PoE switch to complete the installation. Once your system is established, you can view your home circumstance from your computer or smartphone from anywhere. Here focus on how to use a PoE injector to install an IP camera.

What Does a PoE Injector Do?

Power over Ethernet is commonly regarded as PoE for short. It’s a technology that can transfer both power and data over twisted pair Ethernet cables such as Cat5e, Cat6, etc. A Poe injector is a device that is commonly known as the “midspan”. It supplies power to a camera by delivering power into the Ethernet cable. Usually, a power over Ethernet injector converts the alternating current into direct current so it can be the power supplier for low voltage IP camera.

What Does an IP Camera Do?

Unlike the traditional cameras, IP cameras can send and receive data over a LAN or the Internet. It’s a separated unit with its own IP address that needs nothing but a network connection like WiFi or PoE injector switch. IP cameras capture images just like a digital camera, and compress the files for transmission over the network. So these images can be viewed anywhere in the world. Also, this camera can be controlled remotely.

Introduction

First, check the equipment, make sure the PoE injector and IP camera are in good condition. Besides, turn off the devices’ power for safe installation.

Second, plug one end of Cat5e cable into the PoE injector’s PoE/Data out port, and the other end into IP camera’s PoE port.

Third, choose a place to mount IP camera. Usually, the dome IP camera is installed on the roof corner that is adequate to capture the faces of subjects of different heights.

Fourth, use another Cat5e cable to connect PoE injector and a fibre switch.

Last, make sure all connection is correct. Then plug in power to ensure all connections are working normally.

Conclusion

The installation just requires several devices, a PoE injector, an IP camera, a non-PoE switch and some cables, or you can use a PoE switch like 24 port PoE switch to replace the PoE injector. Well, no matter which way you will choose to install your IP cameras, FS.COM is the one-stop shopping base when you need to buy these network devices.
