Source/Destination DAG (SP-DAG)
The SP-DAG uses a hash of source IP (from client) and destination IP address (server). This
mode should be used when source and destination ports are hardcoded (for example 5060). In that
case, a BIG-IP system requires multiple client IP address or multiple
server IP addresses. Keep in mind, most connections are initiated by the client and that's the
"Source DAG" option. In this case, the "Destination DAG" could be a single IP, but the source
client IP should have more that a single IP address.
Key Points
- IP Address Based
- Works best when number of clients is equal to or more than the number of TMMs in BIG-IP system.
- Performance will be impacted if clients consist of only a few SIP Proxy connections. In this case the IP Address entropy will be too low to load balance the incoming packets across available TMMs.
