TCP/IP protocol details volume 1 Study Notes series 3-IP Routing Chapter 9 IP routing This chapter describes the basis of the TCP/IP protocol cluster. IP routing ensures that the correct transmission path can be found for the datagram. If it cannot be found, the sender will
do ISPs control and manage their networks while entering the light internet age? Speed can kill! Control is important if you are playing a car at a 15m.p.h speed on Disney's Autotopia, but you're not going to get hurt. On the other hand, if you find yourself on the Indianapolis500, then, the high performance of the brakes, tires, and driving the controls provided, will be very important for your survival. This article will assume that we have enter
1. Route Selection Protocol The core of routing protocol is routing algorithm, the router uses routing protocol to generate routing table, which can realize the "best" path of the netw
1. Several issues restricting BGP scalability BGP is an IP network protocol currently used on the Internet. It provides stable and secure routing protocols for intercommunication between operators and provides a wide range of routing control mechanisms. To better control routing
Currently, HSRP routing protocols are widely used. So I have studied the application of HSRP routing protocols on campus. I would like to share this with you and hope it will be useful to you. With the increasing popularity of the Internet, people are increasingly dependent on the network. At the same time, this puts forward higher requirements on Network stabili
The RIP routing protocol is mainly a routed-based program. At the same time, routed runs on Unix systems. When the RIP routing protocol is enabled on the network, the network has a powerful function to automatically update the route table. However, some major internal gateway protocols, such as RIP/RIP2, OSPF, or IGRP/
For the router protocol this term, probably many people have been familiar with, especially the current network development quickly, Internet Router Protocol is also constantly improving, but also appeared a lot of new features. The wide application of information technology in various fields has promoted the rapid development of information exchange network, in
The use of routes greatly expands the performance of the network. Next, we will analyze some characteristics of the IBGP routing protocol. Through the introduction of this article, we can understand the routing features in this regard. With the development of the network, ISP needs to connect to the INTERNET through mu
As a key device in the Internet, routers and L3 switches have been widely used. As people have high requirements on the quality of network services, the functions and performance indicators of routers and L3 switches become more and more important. Route tests include consistency tests, interoperability tests, functional tests, and performance tests. The routing protoco
problem, a huge internet, how to believe that so many hop-on route stitching up a complete path is really the most optimized? The answer is clearly definite, and the question is how to prove it.Routing algorithms in the book, the routing algorithm is basically divided into distance vector algorithm and link state algorithm, the respective protocol masterpiece is
In the age of the Internet, we often encounter problems with the distance vector routing protocol. Next we will introduce the knowledge about the distance vector routing protocol, including how to determine the adjacent router to your network. Why is it important to determi
redirection packets (corresponding to the above d, m mark) For example, if an IP data packet is sent to the default route option B in host a, and then B checks the route table to know that the correct route is C, B forwards it to C. At the same time, also, send an ICMP redirection packet to a, indicating that the correct part is C. (Note: These are only the route tables of hosts on the LAN) 5. Dynamic Routing Pro

IETF is setting up a new working group to solve the scalability problem in the Internet routing system. This problem is caused by the Division of network traffic between various operators. The Working Group will be built on a proposal from the Cisco engineer team to build a new tunneling mechanism for Internet edge and core routers. This new approach, known as LI

The RIP Protocol requires that each vro in the network maintain the distance record from itself to each other destination network .? In the RIP Protocol, "distance" is also
This chapter describes the basis of the TCP/IP protocol cluster. IP routing ensures that the correct transmission path can be found for the datagram. If it cannot be found, the sender will be notified of a failure to issue the message. The information used in the route finding process is maintained in two ways: each host maintains its own route table (print the current route table using route print in windo

Global Optimization Principle for Internet IP routing by Hop-Dijkstra algorithm proof, route-dijkstraI made up half of what I wrote over the weekend and achieved a perfect day.One fact we know is that there are too many IP addresses and it is impossible to manage them in a unified manner, either on the data plane or on the control/management plane. Therefore, the IP pro
