SIP Load Balancing

SIP load balancing scales and optimizes a SIP infrastructure. SIP registration and SIP proxy traffic can be handled in separate service groups, whose servers can be monitored with separate application-layer SIP health checks for registration or non-registration traffic. SIP over TCP/TLS infrastructures can be optimized further by using the load balancer to offload SSL processing from the SIP servers.

Session Initiation Protocol (SIP) has gained widespread acceptance within the last few years, notably deployed for Voice over IP (VoIP) networks. SIP is a session-based protocol in the OSI model, or application-layer protocol in the TCP/IP model, that enables the creation, management, and tear-down of SIP traffic for VoIP, as well as other messaging and media applications.

The A10 AX Series of Application Delivery Controllers' SIP load balancing feature provides SIP application intelligence with advanced health checks to efficiently manage SIP traffic for VoIP, messaging and other media applications.
