Bgp

Direct Server Return (DSR) is a networking technique that allows a backend server to learn the original request’s source IP address and respond directly, even behind a load balancer. This results in reduced latency and improved throughput, as well as the ability to filter traffic based on client IP.

The Border Gateway Protocol (BGP) is used for routing information between so-called autonomous systems (AS). A common use case for BGP is for routing traffic between Internet Service Providers (ISPs) — or in large private networks.
