The Internet has had a 40-year-old's birthday, although the media coverage of its placid, but the real mid-life crisis has really come, one of which has been advertised and touted the a core technology, which the Internet can be a nuclear strike against the the system can automatically bypass the failure to find the network path, only when the communication endpoint failure of communication on the Internet will be interrupted. typical dynamic inter-domain routing is BGP-4, OSPF, and is within ISIS.
dynamic routing The direct result: relatively telephone network, the router already can not go on very complex, the world has more than 300,000 route and no signs of slowing down. Of course, CCNA training also can fire up, so after the FA to enter the threshold of a complex technology also too high.
Ipbaobao done on this issue are considered, then only use the dynamic routing of all, the original about 5:
1) the experimental nature of the Internet even aware network planning to do, it can not be unified planning, the network does not know how to do painting, which led to the Internet without the basic network architecture, the path can be dynamic and unpredictable;
2) network is not planning , of course, closely related to this address allocation will only be a lack of unified planning, and address allocation ago no one could predict in advance (a) where the address is located, who has, after the distribution can only know about the location and has a people;
3) year of telecommunications technology has developed, FR, and no practical optical communications, the Internet link is very reliable bottom; 4) router is based on the common server prior, very reliable, and the software is basically a teacher led a group of students doing;
4) non-commercial operation, interconnection of nodes and links are operated by schools and research institutions, and may be closed at any time;
5) political 忽悠 needs. Network the command center of the war, while we Americans during the Cold War nuclear strike against the network is also unbeatable, the Soviets could not nervous?
There may be more reasons, but at least it is now obvious question 5 a: 1) network planning is required, but also can be planned, otherwise the consequences are serious; 2) address can be unified planning, it should be a unified plan; 3) the bottom link has been very reliable; 4) router hardware and software has been dedicated only to of the. last, ipbaobao follow-up will be dedicated to the author to clarify: purely 忽悠. On the contrary, APPA has to work hard but because it was severely criticized by the military.
more and more research and evidence shows that the Internet needs to Byebye a dynamic routing said.
