routing protocols

-layers: the MAC (Media Access Control) layer and the LLC (Logical Link Control) layer. The common L2 standard for LAN and man is IEEE 802 protocol. In the wide area network, HDLC (High-Level Data Link Control, advanced Link Control), PPP (Point-to-Point Protocol, Point-to-Point Protocol), and Frame Relay (Frame Relay) and other protocols are widely used. Routing is a layer-3 concept. The network layer is t

Let's see where we're going to use the bidirectional redistribution of routes. Scene One: The company has 2 technical directors, respectively, management Headquarters and division, the level is similar, director a thinks my side of the router performance is poor, with RIP protocol is enough to use. The head of headquarters thinks that OSPF is better than OSPF. Because of disagreements that led to the division using RIP and the headquarters using OSPF, there is a need to use a two-way redistribu

today will bring you a new technical introduction series, the name of this series is called "Routing technology in the enterprise's specific application" This is the first article series, "Static routing, default route NAT and static floating routing "I think when you see these nouns, you will not be unfamiliar, whether you are learning Cisco Certification syste

Over the past 20 years, network technology has continued to develop, from the initial X.25, frame relay, to Ethernet, FDDI, to the popular ATM, different technologies provide diverse network options. To achieve network interoperability among various types of LAN and WAN, you need to use the network protocol. The network protocol stack used by the Internet not only has low-level protocol specifications, such as TCP and IP protocols, in addition, high-l

The driving force of technological development is the constant demand of people. With the increasing use of the Internet, the current network protocol version is no longer able to meet the needs of the times. Inevitably, we will launch a new generation of IPv6 network protocols that are more complete and have diverse functions. The inevitable elimination of IPv4 indicates that the development of the network will usher in its first innovation. IPv6 is

convert CAN communication to USB, PCI, and other communication methods. A professional bus analyzer is required for comprehensive analysis of the CAN bus. CANScope is a comprehensive set of CAN node testing and calibration, CAN Bus Fault Diagnosis and solution. CAN bus packet capture tools and methods Iii. Application of Multi-channel CAN cards The above-mentioned bus protocol analysis is performed on the premise that there are few bus nodes and the node IDs are known. When faced with a networ

The previous article analyzed the overall concept of the Internet, from bottom to bottom, and the design philosophy of each layer of protocol.This is a question from the designer's perspective. Today I want to switch to the user's perspective to see how users interact with these protocols from top to bottom. ========================================================== ================================= Getting started with Internet

number of blocks NFB ). The first newly generated data packet is the first data segment generated, and the multi-segment mark is 1. The second newly generated data packet is the second data segment generated, the multipart mark is equal to the value in the original datagram, and the segment offset is equal to the value in the original datagram plus NFB. The above process can be expanded from 2 to N. For segment reorganization, the following four domains must have the same values: Tag, source ad

returns a flag indicating that more data can be obtained, and the read operation after the application will return the rest of the datagram. When discussing TCP, we found that it provides continuous byte streams for the application without any information boundaries. TCP transmits data according to the length required by the read operation of the application. Therefore, no data loss occurs in this interface.

The WAN protocol is relative to the LAN protocol, and the Internet can be identified as a wide area network. Then the relevant agreement is well understood. is inseparable from the OSI model. Here are a few typical protocols. To everyone as a reference. The WAN Protocol is a three-tier operation at the bottom of the OSI Reference Model, which defines communication on different WAN media. Mainly used for wide area network communication

application characteristics of local area network data exchange. While routers are different, it is designed to meet different types of network connection, although also applicable to the connection between the LAN, but its routing function more reflected in the interconnection between different types of networks, such as the connection between the LAN and the WAN, the connection between different protocols
