IP Unicast Forwarding Scenarios

The IP (IPv4 or IPv6) unicast packet (Figure 1) is hashed based on the format of the packet when the packet is received on the inbound board (upstream board). The hash factor can be:
  • 2-tuple <source IP address, destination IP address>,
  • 4-tuple <source IP address, destination IP address, source port number, destination port number>,
  • 5-tuple <source IP address, destination IP address, source port number, destination port number, and protocol number>
Therefore, the result of the load balancing depends on the IP addresses and the TCP/UDP port number of the traffic.

Default hash factors of IP unicast traffic depends on the type of the inbound board.
