administrators to create virtual networks to connect internal (physical) networks, virtual machines (VMS) and Hyper-V hosts, or other VMS. The only available real segment control is the local Virtual LAN (VLAN) Tag.With the Windows 8 vswitch, Microsoft has extended a set of APIs and drivers, which simplifies Virtual Devices of network security vendors and allows them to create Virtual Switch Extensions ), www.2cto.com naturally integrates Hyper-V. For example, Cisco's Nexus V vswitch will fully

In principle, they do not view the previously writtenProgramBut the program must have a good programming style (including naming rules for variable functions,Code). Programming is provided in the morning. If you have time, you can try to write other questions. In the afternoon, you can check and accept the questions. During the acceptance, you must first execute the program and

current vswitch, or using a new hardware module to insert it into the existing system, so as to enhance the forwarding performance of IPv4/IPv6; or a brand-new IPv6 10-ge switch. Security and Traffic Management Security and network traffic management are currently the most important topics for users. As a backbone device, you not only need to consider the security of the device itself, but also provide user prevention. That is to say, you must be immune and provide powerful blocking measures to

As an inbound or outbound QoS site, edge switches play a very important role, especially in small and medium enterprises, if the edge devices of the network integrate QoS, rate limit, ACL, PBR, and sFlow into the hardware chip, the Intelligence will not affect the line rate forwarding performance of the basic layer 2 and Layer 3, therefore, the end-to-end smart network can be carried out on a large scale, so that the entire network not only has global

In addition to connecting to the same type of network, edge switches can also interconnect different types of networks, such as Ethernet and Fast Ethernet. I hope this article will help you. With the development of the communication industry, people have higher requirements for intelligence. As a representative of smart exchange devices, edge switches are gradually increasing in market demand. If the edge devices of the network integrate QoS, rate limit, ACL, PBR, and

In today's world, people's computers are interconnected and interconnected. Small to your Home area network (LAN), the largest one is what we call the Internet. When you manage a networked computer, you are managing one of the most critical components. Because most of the developed applications are network-based, the network connects these key points.That's why we need network monitoring tools. NTOP is one of the best network monitoring tools. Knowledge from Wikipedia "NTOP is a network probe th

form, traffic, or feature. For comprehensive communication intelligence, it can also think of the device flow profiling software, which can be used in different order or users to check the use of data, in different time to check the data, and related to multiple origins of the communication data, such as NetFlow and Ipfix. Looking to the future, some of the leaders in it should focus on new skills in order to put them into arsenals. For example, IP
