The primary issue with anycast routing protocol is the tradeoff between performance and reliability. An anycast routing protocol that can provide shorter end-to-end delay does not always has lower packet loss, and vice versa. This paper focuses on achieving short end-to-end delay and low packet loss, and proposes an enhancement to the anycast routing protocol called the nearest Protocol Independent Multicast - Sparse Mode (PIM-SM) extension. This extension supports two load-balancing schemes, i.e. shortest-path and round-robin.
