event of a network topology change. The second is to adjust the routing when encountering network congestion and failure, so the network load can be balanced effectively.
The concept of packet switching for ip-based interconnection, including End-to-end protocol and dynamic route selection, is first proposed for packet switched networks. For wide-area data networks, packet technology is still the dominant technology.
Ethernet Ethernet plays a dominant role in local networking.

The principle of the protection of TE is already mentioned. Today's focus is to explain how the Frr-fast-reroute in Te Protection is configured, and how to look at the state.
Before introducing the configuration, it is important to note that FRR fast rerouting is a protection mechanism.
Imagine if the R2 to R6 is an ordinary IGP network. After the middle link down, what is the situation?
It should be the first problem the router sends the LSA through the other interface and then reddening to

Vimium is an open source plugin on the Chrome browser that allows you to quickly manipulate chrome with Vim's instructions. I found that I only used a few times to switch contexts using shortcut keys, as if they were more familiar with these shortcuts than before. The same extension is also available on Fire

important to choose Scala and Finagle. There are many people within the team who have Ruby and PHP experience, so Scala is attractive. Finagle is one of the most important factors in choosing Scala. This library from Twitter can solve most of the distributed issues, such as distributed tracking, service discovery, service registration, and so on. After going to the JVM, Finagle provides all the basic functionality that the team needs (Thrift, zookeeper, etc.) without having to develop a lot of

Advantages of SIP: Web-like scalable open communication
With SIP, service providers can select standard components at will to quickly control new technologies. Regardless of the number of media content and participants, users can find and contact each other. SIP negotiates sessions so that all participants can agree on and modify session functions. It can even add, delete, or transfer users.
However, SIP is not omnipotent. It is neither a Session Description Prot
