The switch is an important connection "hub" in the LAN, once its working status is unexpected, then all the computers connected to the switch have to "suffer", light is the phenomenon of slow surfing the internet, serious words simply can not go online, for this choice of superior performance, quality of the switch to form some important network, is very critical
The layer-4 switch actually adds the ability to identify the layer-4 protocol port in the layer-3 Switch, meeting more user needs and improving the performance. In recent years, with the popularization of G, 1g, or even 10g LAN.
The wide application of Broadband LAN and even Bandwidth WAN drives the continuous development of switch technology. In enterprise appli
Layer-4 switches are quite common. So I studied the layer-4 switch technology and application. Here I will share it with you and hope it will be useful to you. With the increasing popularity of Mbit/s, Gbit/s, and even Mbit/s local area networks, broadband MAN networks and even broadband wide area networks are widely used. Whether it is Intranet, exclusive, or residential intelligent networks, it is increasingly expanding to massive amounts of informa

Configuration of Cisco3550EMI switch as an instance of DHCP server Engineering
Network Environment:
A 3550EMI switch is divided into three VLANs. vlan2 is the network where the server is located. It is named server, IP address segment is 192.168.2.0, subnet mask: 2
A layer-4 switch is a vswitch product developed through the layer-4 switch technology. A layer-4 switch is not so much a network device as a network management system. In recent years, with the popularization of Mbit/s, Gbit/s, and even Mbit/s, the wide application of Broadband LAN and even Bandwidth WAN has driven the continuous development of
With the increasing popularity of Mbit/s, Gbit/s, and even Mbit/s local area networks, broadband MAN networks and even broadband wide area networks are widely used. Whether it is Intranet, exclusive, or residential intelligent networks, it is increasingly expanding to massive amounts of information, it is forcing people to transmit audio, video, data and other information in the network system more and more demanding.
With the rapid development of Internet, the use of e-commerce, e-government, e
Five, OpenFlow table
This section describes the components that make up the flow table and the group table, and also includes the mechanism of the flow table "matching" and "action" processing.
5.1 Pipeline processing Process
The switches that obey the OpenFlow protocol can be divided into two categories: one is openflow-only, the other is Openflow-hybrid. The openflow-only switch supports only OpenFlow operations, in which all packets are handled

The following article is an effective description of the ethernet switch parameter configuration problem, the switch according to the work protocol layer can be divided into a second layer of switches, third-tier switches and layer fourth switch, according to whether or not to support the network management function can be divided into network-oriented
Compared with the layer-3 switch, the layer-4 switch has a good improvement in its functions and features. Here we have explained the basic knowledge of the layer-4 switch. The amount of transmitted audio, video, data, and other information in the network system is full of bandwidth. We have to provide differentiated services for these data traffic, so that laten
When the main performance of a LAN cannot meet the new application requirements of an enterprise, you must consider upgrading the network.
During the upgrade, you should analyze the problems to be solved based on the requirements of network applications, especially the upgrade of switch hardware devices. This article will discuss this issue with you.
Upgrade network devices
1. Principles for selecting upgraded network devices
When selecting a network
How to solve the problem of Ethernet switch parameters the switch can be divided into Layer 2 switches, Layer 3 switches, and Layer 4 switches according to the working protocol layer, you can divide network-managed switches and non-managed switches based on whether the network management function is supported. This article will describe how to set parameters for the Ethernet

There are many things worth learning about security switches. Here we mainly introduce the meanings and new functions of the layer-3 security switch. Security Switch-the new darling of the network industry, the gatekeeper of the network entry, is aiming to raise a large knife to all insecure factors. With the advent of the Internet era, security issues have become an urgent issue. The existence of viruses,
