White Box switch: three methods for network programmability (1)
Even the most demanding IT professional, one word will attract his attention: cost saving. When there is a white box switch in the market-that is, a kind of consumer switch hardware that is pre-installed with a third-party network operating system, network engineers generally hear or understand that
Example of a switch statement in PHP, Phpswitch statement
Switch is a switching statement, so many friends only know the simple switch switch statement usage, the following tutorial small series for you to introduce the switch usage example.
Only so called "advanced" usage,
1. Configure an IP address on the router that is connected to the switch: for example, 192.168.1.1 242. Configure the following on the switch:[Switch]vlan 10[Switch-vlan10]quit[Switch]interface VLAN 10[switch-vlanif 10]IP Address
When connecting a computer to a switch, it may take 30 seconds or more for the computer to communicate with the network. If you are in a hurry to use, 30 seconds of waiting is enough to make you feel very long. Let's see how we can speed up the port initialization process for the switch.
Understanding the process of switch port initialization
When you connect a
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

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
In order to help enterprise users better understand the meaning of layer-3 Switch, understand the various new technologies supported by the leading layer-3 switch in the current market, and their position and role in the next-generation smart enterprise network, the computer world evaluation lab recently organized a deep technical test on layer-3 switches.
An in-depth analysis of layer-3 Exchange Technology
Layer-3 switches are quite common, so I have studied the comprehensive description of layer-3 switch technology. Here I will share it with you and hope it will be useful to you. The emergence of layer-3 switching technology solves the problem that the subnet must be managed by routers after the network segments are divided in the LAN, and solves the network bottleneck caused by the low speed and complexity of traditional routers.
A layer-3
In addition to connecting to the same network type, the network management switch can support switching between ports at different speeds to ensure the collaboration between high-speed ports and low-speed ports, the following is a study.
Vswitches are the most important network connectivity devices in Lan. Most LAN management involves vswitch management. However, many campus network administrators are still unfamiliar with
SNMP is widely used. So today we will introduce you to the knowledge of SNMP monitoring switches. So what is the specific role of this SNMP monitoring switch? Using SNMP to monitor switches: it is easy to solve switch faults. in the Internet era, we often encounter troubleshooting methods for SNMP monitoring switches. Next we will introduce the knowledge of SNMP monitoring switches, including how to use SNM
