The Open Shortest Path First (OSPF) protocol is a link-state Interior Gateway Protocol (IGP) developed by the Internet Engineering Task Force (IETF).
Using Dijkstra's shortest path algorithm, OSPF calculates the shortest path for all routers in an area of the AS to efficiently use network bandwidth and ensure scalability. The AS may be divided into multiple interconnected networks, such as a wide area network (WAN). Thetopologyis visible onl...
It exchanges reachable routing information between ASs, establishes inter-AS paths, prevents routing loops, and applies routing policies between ASs. BGP has three earlier versions: BGP-1, BGP-2, and BGP-3. The currently used version is BGP-4. ...

Traditional WANs forward packets based on the shortest path. As a result, the resource utilization of both the cloud and the network is unbalanced. Some nodes are full of resource data while some nodes are idle or their resource utilization is low. As the overall network traffic increases year...
Routing Information Protocol (RIP).This dynamic routing protocol uses hop count to find the most direct path between the source and destination network. Open Shortest Path First (OSPF).This is a link-stating protocol based on another algorithm, the Shortest Path First (SPF) algorithm. It uses ...
“traversal queries” based on connections and apply graph algorithms to find patterns, paths, communities, influencers, single points of failure, and other relationships, which enable more efficient analysis at scale against massive amounts of data. The power of graphs is in analytics, the ...
A switch forwards a data packet based on the physical address (MAC address). For theIPprotocol, the switch is transparent. That is, when forwarding a data packet, the switch does not and needs not know theIP addressof the source or destination machine. It only needs to know the destinatio...
