Switch troubleshooting: a layer of equipment is used to help the detector. You are very interested in troubleshooting the switch. Before giving you a detailed description of how to troubleshoot a vswitch, let's first take a look at a layer of

The multi-layer and multi-layer data center network age is almost eliminated. As the data center further implements various abstraction layer technologies, many enterprises have chosen to rethink how to design their data centers and migrate them to

1. High-capacity Devices The network traffic of the data center is characterized by high-density Application Scheduling and burst buffering. Common switches cannot precisely identify and control services for interconnection purposes, in large

Over the past few years, with the rapid popularization and maturity of domestic IP phone technology and successful market operation practices, people have been paying more attention to and enthusiastic about China Telecom's next-generation network.

I. OverviewIn the study of the Next Generation Network, ITU has put forward many suggestions on the meaning, architecture, and services of the Next Generation Network, which will be determined in project. Currently, the second group of ITU has begun

This experiment is to configure a general router as a frame relay switch to provide a frame relay experimental environment for other experiments in this chapter.1. Tutorial PurposeThrough this experiment, you can master the following skills:●

With the rapid development of the Interconnection Network and the advancement of social information, the network is rapidly developing in terms of scale and speed. The speed of the local area network has grown from 10 mbit to 100 mbit, now, Gigabit

1. Introduction In recent years, Softswitch technology has been widely valued by the industry, four international standards organizations, ITU-T, ETSI, 3GPP, and IETF, have conducted research and standards development on Softswitch technology in

In recent years, many words such as broadband speed-up, copper-to-copper withdrawal, and WIFI have been mentioned from time to time. Many applications such as Weibo, mobile payment, and mobile games have become increasingly familiar, the increasing

As the customer's network scale and coverage grow, the use of BGP routing protocols is no longer the privilege of the operator's network, and more enterprise networks are also deploying BGP. BGP can support a larger network, a wide range of routing

The G optical transmission technology based on digital coherent receiving PM-QPSK modulation has a milestone in the long-distance optical transmission technology history. The error correction coding technology can be used to further improve the

Network virtualization is now a hot topic, and major manufacturers are scrambling to grab this cake. Technologies involved include virtual Emulation for NICs, I/O pass-through, SR-IOV), virtual access technology for networks VN-Tag/VEPA), covering

1. Use the ip verfy unicast reverse-path network interface command This function checks each packet passing through the router. In the router's CEFCisco Express Forwarding) table, if the route entry of the packet to the network interface does not

Single-user Cisco Products Some products of the SOHO series use dial-up technology, such as ISDN Integrated Service data network, which allows users to roam from one place to another, or dial to the central site.The Cisco200 series for ISDN has

In the course of the development of IPOA technology, CIPOA (Classic IPOA, that is, traditional lP on ATM), LANE (LAN simulation), and MPOA (Multi-Protocol Transmission on ATM) emerged one after another) IP address switching, CSR (cell Switch Router

MPLS is developed to support IP service on ATM, and is also a type of IP address exchange. Core Routers generally adopt exchange technology. What is the significance of introducing MPLS to core routers? MPLS enables fast switching, QoS, traffic

Wireless Network Application Analysis Today, the pure wired home networking solution has gradually evolved into a combination of LAN and WLAN with the help of wireless technology. I believe that friends who have used wireless products can feel the

With the rapid development of modern Wireless communication technology, Wireless Local Area network (WLAN) is widely used. WLAN uses wireless communication technology to transmit data, voice and video signals in the air, so that users can exchange

With the continuous development of wireless networks, multi-Stream Aggregation (MSA, Multiple Stream Aggregation) can improve the edge throughput by 500% through deep fusion of Multi-standard, multi-carrier and multi-layer networks, realizing the

802.11ac has made great strides in improving Wi-Fi performance by using a wider channel, a more efficient modulation mode (by transmitting data in RF waves), and multi-user connections (so-called multi-user MIMO. In fact, this kind of progress will
