TCAM Based Load Balancing

Catena uses a cross function of IP-ACL entries along with TCAM FIB to bucket the traffic streams to multiple
egress interfaces.

Hash-Load Balancing

Catena uses source IP or destination IP to determine the egress interface. Egress interface ports are bundled
using the link aggregation control protocol (LACP), and hash algorithms are used for symmetric load balancing.
