Abstract: A system and methods for automating membership discovery in a distributed computer network is presented. A first virtual circuit label switch path (LSP) associated with a first VPLS is established between a first multi tenant unit (MTU) and an attached provider edge (PE) device. A first label mapping message (LMM) is communicated over the first virtual circuit LSP and received at the PE device. The PE device broadcasts the LMM to a plurality of additional PE devices. In addition, methods for automating membership discovery for adding and deleting virtual private LAN service (VPLS) sites are presented. A virtual circuit forwarding equivalence class (VC-FEC) type packet utilized in the various methods and system is also disclosed.

Abstract: Methods for automating membership discovery in a distributed computer network are presented. A particular method includes establishing a Multi-Protocol Label Switching (MPLS) tunnel and Targeted Label Distribution Protocol (LDP) signaling channel between a first Provider Edge (PE) device and a plurality of PE devices. A first Virtual Private LAN Service (VPLS) site is added to a Multi-Tenant Unit (MTU) device associated with the first PE device. A first LDP Label Mapping Message is sent to the first PE device from the MTU device. The first LDP Label Mapping Message is broadcast to the plurality of PE devices from the first PE device. A second LDP Label Mapping Message is sent to the MTU device from the first PE device to establish a virtual circuit label switch path between the MTU device and the first PE device. A second VPLS site is added to the MTU device without sending an associated LDP Label Mapping Message to the first PE device. A respective one VPLS site of the first VPLS site or the second VPLS site is deleted using a configuration command.

Abstract: A particular method includes measuring port usage data related to each of a plurality of physical ports associated with a link aggregation group. A bandwidth requirement of a requested media stream is estimated and added to a traffic load at each of the plurality of physical ports to produce an estimated total traffic load of each of the plurality of physical ports. When the requested media stream includes non-video data, the requested media stream is sent to a destination device via a physical port that selected in accordance with a static bandwidth allocation. When the requested media stream includes video data, the requested media stream is sent to the destination device via a least loaded physical port that is dynamically identified based on the estimated traffic loads of each of the plurality of physical ports.
