different switches

switch can judge the routing without unpacking, thus forwarding the packet directly and exchanging data. Thus, different subnet IP packet Exchange can be realized. The other three-tier routing module is not a simple stack of two-layer switches and routers, it is a three-layer routing module overlay Two-layer switching high-speed backplane bus rate up to gbit/s, most of the required routing software process

This section describes the standards that stack switches must meet. Many people do not know what Stack switches are. Let's give you a detailed introduction today. We hope relevant users can get what they want. A stacked switch is a type of switch. According to the design, this type of switch can be stacked on the other. Different from Rack-mounted

different manufacturers use different ASIC, the product performance is directly affected. The above three points are also the main technical parameters used to judge the performance of Layer 2 and Layer 3 switches. Please pay attention to the comparison when considering device selection. (2) routing technology The router operates on the layer 3 of the OSI model-

be 0. Our test shows that the frame loss rate is not zero in the 64-byte test of Thinker3800 and lipleapcomm6004. Latency is used to determine the time when a packet passes through the switch. The delay test results of each switch are quite different. The delay time of the EDIMAXES-5800R of the Gigabit backbone switch is only 3.92us in 64 bytes, network type switch is often longer than the non-network type products Delay Time, and digital China D-lin

Security switches are worth learning a lot. Here we will mainly introduce the features and Technical Development Prospects of Security switches, the new darling of the network industry, and the gatekeeper of the network entry, aim To raise the knife to all insecure factors. With the advent of the Internet era, security issues have become an urgent issue. The existence of viruses, hackers, and various vulner

of this type, which features a simple system structure. Small Size, convenient to use, low price, less protection. The dedicated type is applicable to different units and provides various special functions according to the special needs of each unit. Beijing Group calls. The following describes several special user-controlled switches: I. Hotel type The hotel-type programmable User Switch has a large numbe

industry is mainly intended to attract a large number of users and achieve better financial return. We must make more efforts in terms of business strategies and infrastructure. Today, it is said that switches are a very basic but important part of Internet cafe networking devices. Internet cafe switches are the hub for data transmission between Internet cafe computers. Many online video applications of LA

At present, there are two ways to increase the density of the switch port in the local area network : One is to use the chassis switch, support multiple module slots, by adding modules, you can meet different port density requirements; the other is to stack the switches with a tiered switch, And through a single IP address, the entire tiered switch for integrated management, the general number of stacks is

proportion. Generally, it accounts for about 70% of the total traffic. Currently, program-controlled air separation user switches of less than 200 doors are of this type, which features a simple system structure. Small Size, convenient to use, low price, less protection. The dedicated type is applicable to different units and provides various special functions according to the special needs of each unit. B

Layer-2, layer-3, and layer-4 switches have different characteristics. layer-2 switching is a mature technology. A layer-2 switch is a data link layer device that can identify MAC address information in data packets, forward based on the MAC address, and record these MAC addresses and corresponding ports in an internal address table. The specific workflow is as follows: (1) When the switch receives a packet

LAN switches are quite common, So I studied the basic technical indicators of LAN switches and shared them here. I hope they will be useful to you. There are many basic technical indicators for LAN switches. These technical indicators fully reflect the technical performance and functions of LAN switches. They are impor

, logically the bus structure.In recent years, the technology of switched LAN has been able to solve a series of problems, such as low network efficiency, insufficient network bandwidth and difficult network expansion. It fundamentally changes the structure of the shared LAN, and solves the bandwidth bottleneck problem. At present, switched Ethernet, switching token ring, switched FDDI and ATM switched LAN, which is the most widely used in switching Ethernet. Switched LAN has become the mainstr

performance of the switches, including one-to-one throughput, frame loss rate, latency, and Back to Back, even more rigorous mesh tests show us the progress of switch technologies and products over the past year. Although we still insist on using a strict test time of 120 seconds, the tested switch can withstand this pressure for several indicators specified in RFC 2544, the tests were quite successful. The frame loss rate of all vswitches is 0 for t

First, let's start with a simple understanding of the differences between switches and hubs. The hub uses the shared bandwidth of the work, simple for example, the hub is like a one-way street, "10M" bandwidth is used in multiple ports, when a port occupies most of the bandwidth, the other port will appear very slow. Instead, the switch is a unique channel that ensures that each port uses bandwidth, such as a hundred gigabit switch, to ensure that eac

accounts for a large proportion. Generally, it accounts for about 70% of the total traffic. Currently, the programmable Air Separation user switches with less than 200 doors produced in China are of this type. their special features are simple system structure, small size, convenient use, low price, and less protection. The dedicated type is applicable to different units and provides various special functi

optimal network security control should start from the network edge, that is, the network and the Internet or user access, and distribute the network security shielding and policy execution capabilities to the network edge. For enterprise networks, authentication and access control are usually required when users access different network service resources. For example, you can bind a MAC address to a port to restrict access from a specific port. In a

GMS5596 vswitches provide three expansion slots on the rear panel. One of them is specially prepared to insert the SNMP Network Management Module. This is a very careful design, for users who do not have high requirements on network management, they can pay less. From the stack method, there are two main methods: Star and chain stack. Digital D-Link DES3624 and Trendware TEG-S224M series is a typical star stack switch, but the switch has obvious master-slave points, only the host can plug in Gi

Layer-3 switches are quite common, so I have studied the basic principles and design ideas of the layer-3 switches. I will share them with you here, hoping they will be useful to you. Based on the introduction of the three-layer switch technology and the working principle of the three-layer switch, the design of a three-layer switch is given. According to the design, the three-layer switch has been put into

trend. Intelligent networks are affecting almost all network devices. Recently, layer-3 switches deployed on the edge of the network have seen significant changes. In this test, we used the latest TestCenter Tester of Spirent for the first time, and conducted an in-depth test on several typical layer-3 switches on the market. The test results can be used as a reference for enterprises to select and deploy

Layer-3 switches are quite common, So I studied the market trend of layer-3 switches and shared them with you here. I hope they will be useful to you. It can be said that all core backbone networks must use layer-3 switches. From a medium-sized campus network to an enterprise's backbone network, metropolitan area network backbone, and aggregation layer are all th
