First, the nature of the routing algorithm

The algorithm is correct and complete ; the algorithm in the calculation should be as simple ; algorithm can adapt to changes in the network ; algorithm is stable and fair of.

 

 

 

The size of the Internet is very large, the environment is very complex, so the Internet is divided.

 

Second, the autonomous system 

AS (Autonomous System);

An autonomous system (AS) is a group of devices in a network under a regulatory agency;

AS own internal network management, provide one or more AS an outside (the) inlet.

 

Agreement autonomous internal routing system called: interior gateway protocol (RIP, OSPF)

Agreement autonomous external routing system called: Exterior Gateway Protocol (BGP)
