Title: LAYER-2 EXTENSION SERVICES
Abstract:
Methods, apparatuses, and systems for providing layer-2 extension services through a non-routed ground segment network, are described. The method includes providing a Layer-2 (L2) interface between a node of the non-routed ground segment network and a service provider, assigning a virtual tagging tuple to the service provider and receiving service provider traffic at a node of the non-routed ground segment network. The method further includes tagging the service provider traffic with the virtual tagging tuple, and switching the tagged service provider traffic through the non-routed ground segment network according to the virtual tagging tuple. The methods, apparatuses, and systems are particularly useful satellite communications systems having a layer- 2 switching infrastructure. Preferably, the vertical tagging tuple is implemented as a VLAN tag according to the IEEE 802. IQ standard.
