ABSTRACT:
A system for transporting downstream and upstream traffic between service providers and end user terminals is provided. The system may include an apparatus having multiple egress ports configured for transmitting downstream traffic received from the service providers towards nodes adapted for replicating the traffic, at one network layer, and further transmitting the replicated traffic toward the end user terminals. The system may further include a merging unit coupled to ingress port of another apparatus receiving upstream traffic from the user end terminals, where the merging unit is adapted for merging the upstream traffic, at a different network layer, according to which service provider the upstream traffic received from the end user terminals is intended to and for transmitting the merged traffic toward the service providers.
