Description: Interdomain Policy refers to the rules and guidelines governing routing between different autonomous systems (AS) in the context of the Border Gateway Protocol (BGP). In networking, an autonomous system is a set of IP addresses and routers under the control of a single administrative entity that presents a common routing policy. Interdomain Policy is crucial for managing data traffic on the Internet, as it allows different AS to communicate and decide how to route traffic between them. This policy is based on attributes such as path length, local preference, and routing policies defined by each AS. Implementing these policies ensures that traffic is directed efficiently and that the preferences of each network are met, which may include considerations of cost, performance, and security. In summary, Interdomain Policy is an essential component for the functioning of Internet routing, facilitating the interconnection and cooperation between multiple independent networks.
