摘要： Methods and Systems are provided for a distributed Provider Edge (PE). A single Virtual Routing and Forwarding device (VRF) is associated with a single customer site. The VRF includes a single routing table (RIB) and a single forwarding table (FIB). The VRF also includes a plurality of Virtual Private Network (VPN) Protocol Instance Modules (VRP), where each VRP is associated with a different VPN from the customer site. Each VRP accesses the RIB directly and the FIB indirectly to acquiring addressing/routing information for a received data packet. Moreover, each VRP uses a data plane of the VRP to communicate the data packets to a PE backbone device. In turn, the PE backbone device uses the data plane to communicate with each of the VRPs, and the PE backbone device communicates with one or more tunnels.

摘要： Methods and systems for a distributed provider edge are provided. According to one embodiment, a one-to-one association is formed between a Virtual Routing and Forwarding device (VRF) of a provider edge device (PE) of a service provider and a customer site. The VRF includes a routing information base (RIB) and a forwarding information base (FIB). A network interface module is instantiated within the VRF for each network interface employed, such as an intranet, extranet, Virtual Private Network (VPN) and/or Internet interface. A first packet is received at the PE via a first network interface. A first network interface module associated with the first network interface accesses the RIB to acquire routing information for the first packet. A second packet is received via a second network interface. A second network interface module associated with the second network interface accesses the RIB to acquire routing information for the second packet.

摘要： Methods and systems are provided for bridging heterogeneous media packets using a single processor resource having a virtual bridge. Network interfaces associated with heterogeneous media channels relay network packets to the virtual bridge. The virtual bridge accesses metadata associated with the relayed network packets and translates the network packets between media formats. The translated network packets are then relayed to an appropriate network interface. In one embodiment, the virtual bridge is dynamically configurable within the processing resource.

摘要： Methods and systems for bridging network packets transmitted over heterogeneous media channels are provided. According to one embodiment, a network-computing device comprises multiple network interfaces (netmods) and a shared processing resource. The shared processing resource executes a virtual bridging application representing a single bridging domain for all network packets received by the network-computing device. A translation data structure defines translations between a first framing media format and an intermediate format and between the intermediate format and a second framing media format. If the virtual bridging application determines a network packet is to be relayed between a netmod operable to receive network packets encapsulated within the first framing media format and a netmod operable to transmit network packets encapsulated within the second framing media format, then it uses the translation data structures to translate the network packet before relaying the network packet.

摘要： Methods and systems for bridging Ethernet frames transmitted over heterogeneous media channels are provided. According to one embodiment, multiple Ethernet frames encapsulated within multiple in-bound media transmissions having different media formats are received via a first set of multiple network interfaces of a network-computing device. The multiple in-bound media transmissions are relayed via a switch fabric of the network-computing device to a virtual bridge application running on a processing resource shared by the network interfaces and which acts as a single bridging domain for all Ethernet frames. The virtual bridge application encapsulates the multiple Ethernet frames within multiple out-bound media transmissions by performing media agnostic Ethernet bridging of the multiple Ethernet frames. The multiple Ethernet frames are transmitted by relaying, via the switch fabric, the out-bound media transmissions to a second set of the multiple network interfaces.
