1. Introduction:(1) Internet structure:Information:IP grouping (Directed broadcast address) that specifies " all hosts " in a particular network. ）Nodes: routers, host-----> select paths, Delivery groupingsChannel: physical network (between routers)-----> Transfer IP packets(2) Delivery and routing options--->1. Delivery ( delivery ): Physical forwarding of groupingsdelivery is done by Routed Protocol ( the

In the family of routing protocols, the most basic is the RIP routing protocol. Next, let's take a closer look at the specific principles and algorithms of this Protocol. Some of the basic principles are also used in subsequent protocols. Measurement Method The RIP measurement is based on the number of hops (hops count

We will summarize some of the features of the RIP routing protocol. We hope to help you consolidate your basic knowledge in this area. The RIP routing protocol is a dynamic routing protocol. So I don't know if you have clearly def

Among all the previously introduced routing protocols, only the protocol for the National interconnection project of the IT Training Center of Rongxin foreign companies IS the network protocol of China. The use of the OSPF Protocol requires that all devices use Cisco products, which greatly increases the cost of devic

This article discusses attacks on the underlying network protocols and methods to prevent attacks, especially Routing and Routing Protocol vulnerabilities, such as Routing Information Protocol (RIP, Routing Information

This article describes how to implement VRRP under Linux (Virtual Router redundancy Protocol The redundancy protocol for the router). I am in the learning VRRP process of a small summary, and combined with a number of other information on VRRP some of the basic concepts, principles and how Linux to achieve VRRP an introduction. 1, VRRP Introduction When we set up a network, in order to ensure stable and u

1. Route Selection Method (1) Basic Ideas Instead of selecting routes for an IP group, you can obtain all the routes (Routing Protocol) in advance) Forward IP packets by a predefined route (route table) (2) route reservation:Route table(Route table) Route tableIt can also be calledForwarding Table) HostAndVroRoute tables are used for PacketSend,Forwarding 2. In

In IPv4, you must manually set the gateway address. The IPv6 protocol consists of two types of ICMP6 packets: RS and RA. The protocol is used to help nodes in the LAN find gateways or routers, so that the nodes can communicate with the Internet. On the other hand, for new IPv6 nodes that just access the network, you can set your own IPv6 address based on the gateway or route information to communicate with

Is Anza by the table fast? Or check the socket hash table fast? This is not the root of the problem. The root of the problem is how to use the two effectively, making the two partners rather than competitors. What's going on?We know that if a packet is to arrive locally, it will go through two lookups (temporarily regardless of Conntrack): The IP layer finds the Routing and Transport layer to find the socket. How to merge the two.The Linux kernel

The hot backup routing protocol provides fault tolerance and enhanced routing selection for IP networks. It is a unique technology of the cisco platform and ensures that when the network edge or access link fails, user communication can be quickly and transparently restored, and redundancy is provided for this IP network. How HSRP works: HSRP allows you to quickl

Brief Introduction to the configuration process of OSPF-based Huawei switch routing protocol. The configuration of Environment Parameters in Huawei switch routing will be covered in the following text, including the relevant configuration process, will be displayed to you. Invest in the world of Huawei switch routing.

Socket lookup cache Routing Mechanism of Linux kernel protocol stack Is it faster to query the route table? Or is it faster to query the socket hash table? This is not the root of the problem. The root cause of the problem is how to use the two effectively, so that the two can become partners rather than competitors. What's going on? We know that if a data packet is to arrive locally, it will go through two

IGRP Protocol IGRP (Interior Gateway Routing Protocol) is a dynamic distance vector Routing Protocol designed by Cisco In The Middle Of 1980s. Use a combination of user configuration scales, including latency, bandwidth, reliability, and load. By default, IGRP sends a route

RIP Theory SectionHow RIP routing protocols work:v Regular Updates (periodicupdates): Updates are sent each time a specific period of the cycle is passed. Neighbor (neighbors): A router that shares the same data. v Broadcast Update (broadcastupdate): When the router is first activated, it uses the simplest method to send update information to the broadcast address. v fullRoutingtable update: broadcasts its entire
