NettetInternet approach to scalable routing Intra-AS routing –Routing among hosts, routers in same AS (“network”) –All routers in AS must run same intra-domain protocol –Routers in different AS can run different intra-domain routing protocol –Gateway router: at “edge” of AS, has link(s) to router(s) in other AS’es Inter-AS routing NettetInternet inter-AS routing: BGP • BGP (Border Gateway Protocol): the de facto inter-domain routing protocol – “glue that holds the Internet together” • BGP provides each AS a means to: –eBGP: obtain subnet reachability information from neighboring ASs. BGP “speakers”. –iBGP: propagate reachability information to all AS-internal ...

Nettetrun the same intra-AS routing protocol. Special gateway routers in the various ASs run the inter-autonomous system routing protocol that determines the routing paths among the ASs. The problem of scale is solved since an intra-AS router need only know about routers within its AS and the gateway router(s) in its AS. NettetInter-domain routing. Inter-domain routing is data flow control and interaction between Primary Domain Controller (PDC) computers. This type of computer uses various computer protocols and services to operate. It is most commonly used to …

Nettet5. Intradomain routing protocols ignores the internet outside the AS (autonomous system). Interdomain routing protocol assumes that the internet contains the collection of interconnected AS (autonomous systems). 6. Some Popular Protocols of this routing are RIP (resource information protocol) and OSPF (open shortest path first). NettetEach AS has only one gateway router: • Intra-AS routing algorithm has determined the least-cost path from each internal router to the gateway router • Upon receiving the packet, gateway router forwards the packet on the one link that leads outside the AS. • The AS on the other side of the link then takes over the responsibility
