OPTIMIZED TECHNIQUE TO FORWARD BROADCAST TRAFFIC TO DESTINED USER NETWORK INTERFACE (UNI) PORTS IN A PASSIVE OPTICAL NETWORK (PON)

摘要

Optimized technique to forward broadcast traffic to destined user network interface ports in a passive optical network. The present invention relates to forwarding broadcast traffic in a gigabit passive optical network (GPON) and, more particularly, to an optimized technique for forwarding broadcasting traffic to destined user network interface (UNI) port in an optical network unit (ONU) of a GPON. The broadcast traffic is generally replicated and flooded to all the UNI ports, leading to overloading of the ONU software/hardware. Also data security gets compromised as broadcast traffic is flooded to all the UNI ports and can traffic may be spoofed by any person sharing the same ONU. A network VLAN is added to the broadcast frame, and a network customer VLAN mapping is used to categorize, replicate and forward received broadcast traffic to destined UNI ports configured by the service provider after performing configured egress behavior for each customer VLAN.
