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 fiber 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 center 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 of 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 effected due to the excessive false flooding. At this moment, 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 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.

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.

How to Use a PoE Injector to Install an IP Camera

Preparation

Before the installation, we should prepare a PoE injector, IP camera and Cat5e cables. Here, we will choose the products, single port 10/100/1000M Gigabit PoE injector, 3MP indoor/outdoor dome IP camera with infrared from FS.COM as an example.

  • Single port 10/100/1000M Gigabit PoE injector fully complies with IEEE 802.3af. It has two RJ45Ethernet ports, one is labeled Data In and one is labeled PoE/Data Out.

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 fiber 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.

Understanding the Two Terms: EVPN vs VXLAN

EVPN vs VXLAN is one of the most popular network technology. They were developed because enterprises need to deliver data and share resources at different geographical locations. Therefore, the efficient, reliable and high speed interconnection is required for the different sites. EVPN vs VXLAN are born as the new upcoming technology to meet today’s network demands.

Introduction of EVPN vs VXLAN

What Is EVPN

EVPN or Ethernet VPN, is regarded as a next generation all-in-one VPN technology. It offers Ethernet multipoint services over MPLS (multiple protocol label switching) or IP networks. Using EVPN service and with the help of MPLS core network, users can connect the offices located in different areas via the lay 2 network for sending messages. This is similar to the work that extends LAN to WAN. Also, it greatly reduces the difficulty of network deployment and maintenance. In addition, EVPN supports MPLS, VXLAN, and other data plane encapsulations.

EVPN vs VXLAN——EVPN

Figure 1: Example of EVPN

What Is VXLAN

VXLAN is short for Virtual Extensible LAN. As the name implies, we know this technology is designed to provide the same transmission service for Ethernet connection that VLAN do today, but in a more extensible way. Technologically, VXLAN is a MAC in IP/UDP encapsulation technique with a 24 bit segment identifier in the form of a VXLAN ID, which is larger than the LAN with 12 bit segment ID. Also, it supplies a way to span Layer 3 network by VXLAN tunnel that is established between VETP (VXLAN Tunnel End Point). Thus it has a higher scalability to address more Layer segments.

vxlan

Figure 2: Example of VXLAN

Route VXLAN with EVPN

EVPN vs VXLAN are both virtual technology. VXLAN explained that EVPN could be the control plane of VXLAN, which uses the BGP (Border Gateway Protocol) to provide high scale, multi-tenant separation and fast convergence for host and VM mobility. So EVPN helps us to deploy VXLAN tunnels without controllers. Routing VXLAN is available in two architectures—centralized or distributed. Compare these two approaches, it’s clear that the distributed architecture will simplify the traffic flow. And here is the place for routing VXLAN with EVPN according to VXLAN tutorial.

For the distributed architecture, asymmetric IRB (integrated routing and bridging) and symmetric IRB are the two models to achieve inter-subnet routing with EVPN. Both of them are valuable, so choose the suitable model for your legacy network system.

FS.COM Solution for EVPN vs VXLAN

Open frame rack, thanks to its reasonable price, and material saving, has attracted more and more customers. It is more convenient to ship and be packed. To help you better understand the open frame rack, this article will introduce it in three aspects.

Brief Introduction of Open Frame Rack

The open frame rack is an equipment to mount your servers and other network equipment. When you deploy equipment and organize cables in a computer room or data center,it is important to make proper and reasonable space utilization. Therefore, open frame server racks come at a right time to help stay organized in a cost-effective manner. Here I list four benefits of open frame server racks and why you should consider them for you equipment storage needs.

2-post open frame rack

Benefits of Open Frame Rack

Better Cable Management

The fact that you may run the cables with obstacles from doors and panels won’t frustrate you when using an open frame rack. It is just formed by 2-post racks or 4-post racks with no limitations to each orientation. With this rack, you will not consider whether it can contain all your applications within the space any more.

Airflow

The enclosed racks are not easy for ventilation. Open frame server racks, on the other hand, allow for unrestricted airflow, preventing heat build-up. The proper cooling is conducive to the running of the whole system.

Easy Access

Without barriers, you can access to every equipment and route cables freely in every direction you want. And all the organs and working status are visible to you for real-time monitoring.

Cost

Open frame server racks are a cost-effective way to manage equipment, compared to enclosed racks.

SDN vs NFV: What Is the Difference?

SDN and NFV that have emerged in recent years, are the most aggressive technology in the networking industry. SDN NFV are born to provide new ways to design, build and operate networks. What is SDN? What is NFV? SDN vs NFV, what’s the difference? Here talks about SDN and NFV.

SDN and NFV

Figure 1: SDN and NFV

SDN vs NFV—Definition

What Is SDN

SDN, software defined networking, started from the campus network. It developed to solve the network issue that people had to change the software of their devices when they tried to deploy a new protocol. SDN is a telecommunication revolution that separates the control plane of a network from the data plane that forwards one’s network traffic, aiming at creating a centrally managed and programmable network. As an innovative architecture of new network, it provides a way to implement network virtualization.

What Is NFV

NFV, network function virtualization, is developed by dozens of large telecommunication service providers. Often times, it’s difficult for them to accelerate the implement of new network services due to the restrictions of hardware-based appliances. Thus, the goal of NFV is to virtualize the network services such as DNS, caching, etc., and abstract them from the hardware on which they run, and hence they can run in software. NFV is a disruptive technological reform that offers a more open and flexible service deployment for telecom operators’ network architecture.

SDN vs NFV—Difference

From the above, we know SDN and NFV rely on virtualization so that the network design and infrastructure can be abstracted in software. But do you know the difference of SDN vs NFV?

SDN vs NFV example

Figure 2: SDN vs NFV

Basically, SDN abstracts physical devices like data switch or router and makes the controller process to a virtual network control plane. In this way, the virtual control plane will decide the locations for sending traffic. By contrast, NFV is designed to use the standard x86 server to replace the dedicated network devices like the firewall. As a result, the network function is independent from the dedicated devices, which enables the network to develop without extra devices. The table below shows the differences between SDN and NFV.

SDN vs NFV—Future Outlook

Since SDN and NFV share the same aims that improve software-based  approaches to create more flexible, scalable and perfect networks to support the increasing business demand, they have become popular in the network industry. And there’s no doubt that SDN and NFV will work together with traditional switches or some other optical equipment in the future. To follow the technological trend, FS.COM has developed SDN switches to satisfy customers’ various needs.

The N5850-48S6Q SDN switch offers 48 SFP+ 10GbE ports and 6 QSFP+ 40GbE ports that support non-blocking exchange. It adopts 1.44Tbps full-duplex switch capability with the operating system of broadcom ICOS, creating a more open installation environment for users. Compared with the traditional switch, this SDN switch separates the data path from the control path, which helps to make a high-level routing decision.

Figure 3: SDN Switch

Conclusion

As regard to SDN vs NFV, we have learned the basic information of them. Also, we recognize that SDN and NFV will make a difference in the future. FS.COM, the supplier of switches such as 10gb switch, 40GbE switch and even 100GbE switch, will keep pace with the innovations of network world.

How to Choose a 48 Port Patch Panel?

Patch panel, the critical component in the data center, comes in various types. The port density of a patch panel may not be your primary consideration, but it indeed matters as the ports directly affects the cable management needs either at present or in the future. The number of these ports vary from 12, 24, 48, 64, 72, 96 to 288 and even more. Actually there is no limit to the number of ports on a patch panel. In this article, I’d like to share a buying guide about 48 port patch panel.

48 Port Patch Panel: Copper VS. Fiber

No matter how many ports they have, patch panels can be deployed in fiber and copper cabling system to organize and distribute cables. The 48 port patch panel is no exception. There is no practical difference in performance as the role of patch panels is to direct signal traffic rather than send the signal. However, there is indeed a difference between the cables they will wire. Fiber patch panel is mainly used in fiber optic cable management, while copper patch panel is designed for both shielded and unshielded copper cables like Cat5e, Cat6, Cat6a, and Cat7.

Copper 48 Port Patch Panel Recommendation

As for the copper patch panel, it is designed according to the copper cable types. Sometimes, Cat5e, Cat6 or other Ethernet cables need to be managed in a single panel. In this situation, the blank keystone patch panels can support mixed cabling with installation of different rj45 insert modules. The 48 ports blank keystone/multimedia patch panel, manufactured by FS.COM, is made of SPCC CRS material. It can accommodate all keystone jacks, including RJ45 Ethernet, HDMI audio/video, voice and USB applications. In addition, the high density 19in wide, 1U High, panel design will save valuable space in the rack. With it, you can customize your patch panel according to your specific application.

What Is VLAN Switch and Why Do We Need It?

VLAN or virtual LAN is a type of LAN that is defined to map workstations based on everything except for geographic location. It develops when the network has increased in size and complexity, and many companies require more access ports or a network design. Basically, it’s a networking technology which allows the network to be segmented logically without geographic restrictions. But how much do you know about VLAN switch?

What Is VLAN Switch?

VLAN switch is built on the fiber optic switch of LAN, which realizes the division and management of logical working group as a software. As defined in IEEE standard 802.1Q, VLAN switch can provide a way to transform one network into multiple broadcast domains. And each broadcast domain is usually matched with IP subnet boundaries, so that each subnet has its own VLAN. Therefore, users can obtain various wired LANs for different purposes that are co-existed physically, which means you don’t need to buy additional hardware or cabling at a large expense. With the development of IoT, VLAN switch is extremely useful.

VLAN switch

Figure1: VLAN Example

Why Do We Need VLAN Switch?

As an important feature of modern network technology, VLAN switch not only can create a separate broadcast domain, but also isolate traffic. Besides, it enjoys several advantages as followed that help to optimize the network.

  • Security. Separating system of the VLAN switch can isolate the sensitive data from the general network, so that people will have slim chance to see the information that they aren’t authorized to see.

  • Performance. With LAN data rates increase, traditional routers may generate a bottleneck when sending data in software. VLAN switch can settle this issue. It can segment LAN into VLANs to achieve multiple broadcast domains, which helps to reduce unnecessary network traffic and increase the bandwidth. After a successful setup, VLAN switch will benefit the whole network performance.

Where to Buy VLAN Switch

Using network switches to realize VLAN switch is today’s common solution for network congestion. FS.COM develops a series of network switches such as 1G switch, 10GbE switch, 40G switch and 100G switch. Some products offer VLAN such as S3800-24T4S 24-port 10/100/1000 base-T Gigabit stackable managed switch and 24-port Gigabit PoE+ managed switch, while some are without the support of VLAN like S5800-48F4S 48-port Gigabit SFP L2/L3/MPLS switch and N8000-32Q (32*40GbE) 40GbE spine/core layer switch. Now, we’ll take 24-port Gigabit PoE+ managed switch as an example.

This S1600-24T4F PoE network switch supports 24 RJ45 ports with each PoE power consumption at 30W. For safety, each port is equipped with separated overload and short-circuit protection, and along with LED to show power status. When connected with CAT5e, each port can achieve single port power and data transmission. It accepts the dual-mode PoE standard and compliant with IEEE802.3af/at. Besides, its switching capacity can reach 52Gbps. The switch helps secure the network through supporting dynamic or static binding by users’ definition like IP, MAC, VLAN and so on.

Figure2: 24-Port Gigabit PoE+ Managed Switch

Summary

VLAN switch is a wonderful technology and tool to assist your network. Using FS.COM VLAN switches just by logging into the switch and entering the parameters for the VLAN, you can easily create a VLAN and enjoy your perfect networking experience.
