Solution to IBGP horizontal segmentation: Horizontal segmentation of IBGP: when a router learns a BGP route from an IBGP peer, it will no longer announce the route information to other IBGP peers.         1. Route reflector: Principle: An IBGP is configured as a routing reflector (RR), and the device configured as a routing ...

Network programming 1. Network foundation TCP/IP protocol generally refers to the internet protocol. Only computers using TCP/IP protocol can connect to the Internet. 1.1 IP address In the Internet, an IP address is used to uniquely identify a Network Interface.

WebSocket notes Websocket: HTML5 WebSocket is designed to replace polling and long connection, so that the client browser has the instant messaging capability of desktop system under C/S framework, and realizes full duplex communication between browser and server. It is based on TCP. Although websocket transmits data through TCP like HTTP, ...

1, Project introduction UDP network broadcast communication is realized by using QUdpSocket class. Its principle is shown in the figure below. The working principle of UDP is: the UDP client sends a certain length of request message to the UDP server. The message size limit is related to the protocol implementation of each system, but it ...

Some time ago, because Dubbo's interface was used, I learned the RPC call method of Zookeeper+Dubbo and summarized a Blog [SpringBoot learning notes 14] integrated development of SpringBoot+Dubbo+Zookeeper Recently, because there is a contract related development task that uses Retrofit2 extensively, which was also a half familiar imitation bef ...

Network type Point to point: only two nodes can exist in a network segment MA Multiple access--In the same network segment, the number of nodes is not limited. Normally, there is a layer-2 address, otherwise unicast cannot be performed BMA -- broadcast multi-access NBMA -- Non broadcast multiple access The network type is distinguished ba ...

OSPF comprehensive experiment Irregular area of OSPF 1. Non backbone away from backbone 2. Discontinuous backbone Better solution: Multi process two-way republishing; ospf multiple processes: multiple processes on a router. Each process has its own database, calculates routing entries independently, and calculates all non shared; Finally, all ...
