ABSTRACT:
The present disclosure is generally directed to systems and methods associated with data communications. In a particular embodiment, a method for use of multi-protocol labels switching (MPLS) encapsulation with control word communicated over a distributed computer network is disclosed. The method includes providing MPLS virtual circuit label with the control word associated with a data packet selected from one of a customer data packet and an OAM data packet, and communicating the MPLS packet with control word and the data packet over the distributed computer network.In another embodiment, a method of handling a data packet within a computer network is disclosed. The data packet is either an unknown unicast, multicast, or broadcast packet. The method includes encapsulating the packet into a multi-packet label switching label and a control word, the control word having a source site identity and a multi-cast identity; and distributing the packet to a plurality of sites within the computer network.
