belongs to the external gateway protocol EGP. 7.6.1 BGP and AS numbers The final route control table of BGP is represented by the network address and the router Group of the next stop. However, it performs route control based on the number of passed. 7.6.2 BFP is a path vector protocol 7.7 MPLS Currently, in addition to routing technology, tag switching technology is also used in the process of forwarding IP data packets. The routing technology is

code, virtual connection virtual concatenation, and Link Capacity Adjustment Scheme-LCAS. GSMP is designed to implement multiple data services and use statistical multiplexing to work with existing underlying transmission links. This not only improves the efficiency of transmission bandwidth usage, but also guarantees the QoS and SLA of connection services. It can be said that green is a simple and easy-to-use Adaptation Mechanism for transmitting Ethernet and Fiber Channel in the fiber network

It provides dual-power 1 + 1 backup modules with redundant backups and passive backboards; provides software hot Patching Technology to completely smooth upgrade of equipment; supports dynamic routing protocols, MPLS Traffic Engineering, and provides protection mechanisms such as IP/

It is very useful to learn about the cell packaging technology. So I studied the cell Packaging Technology in Cisco routers. I will share it with you here, hoping it will be useful to you. Cell packaging, also known as cell concatenation) is a mechanism that encapsulates multiple cell relay asynchronous transmission modes (ATM) cells into the same IP/MPLS group. It enables telecom operators to overcome the low bandwidth efficiency inherent in cell rel

How DCN and SDN meet new requirements New Technology of ip ran Network The traditional 3G/B3G network needs the basic bearer network to provide the Layer 2 capability to meet the needs of the Upper-layer network mobile service return. However, due to the introduction of S1-Flex and X2 interface, the basic bearer network must have three-layer switching capabilities. Based on the dynamic IP/MPLS protocol and key technologies, the ip ran is a solution t

the same time, so that J in the denominator can be eliminated.The plural also conforms to the exchange law, combination law, and allocation Law in the algebraic operation:A B = B(A + B) + C = a + (B + C)A (B + C) = AB + AC 2. Polar representation of the plural number As mentioned above, Cartesian coordinates are used to represent the plural. In fact, polar coordinates are more commonly used, for example: M in is the magnproduct, which indicates the distance from the origin point to the coordi

The reliability of metropolitan area Network router is embodied in the following two aspects, one is the reliability of the equipment layer, the other is the reliability of the network layer. The network reliability is an important content of the reliability guarantee of metropolitan area Network router, because the traditional router protocol converges slowly (IGP in the second level, BGP in the minute level), can not meet the demand of carrying real time service. Network rel

A few days ago, I published an article about how to generate a curve. For more information, see Mathematical graphics (1.11) Rose Line Mathematical graphics (1.27) flowers In this section, the two-dimensional curve is converted into a three-dimensional curve, which looks much more beautiful. For related software, see: Mathematical graphics visualization tool. Use script code with custom syntax to generate mathematical graphics.

technology below the IP network layer, that is, the WAN technology mentioned above. In general, the topology of the core network is basically a large ring structure with a self-healing function, and the specific encapsulation can adopt various technologies, but almost no direct IP address encapsulation, because IP exchange is not a real exchange, it requires additional computing in it. These additional computing is routing search and address resolution. The core network exchange is basically a

Due to the slow convergence of traditional router protocols (IGP in seconds and BGP in minutes), it cannot meet the requirements for carrying real-time services. Network reliability is also an active area in the new technology of man routers. Currently, the new network-layer reliability technologies mainly include fast convergence of IP routes, end-to-end LSP backup,

Differences between hybrid WAN and SD-WAN, wansd-wan differences The concepts of hybrid WAN and SD-WAN are often misused, and some people think they can replace each other. Hybrid WAN is a way of routing traffic across multiple connection paths, software-defined WAN (SD-WAN) Simplifies WAN management by centrally managing and providing business policy orchestration and security. These two methods have evolved into an important technology that supports the changing network needs of the cloud era
