Abstract: Techniques are described for forwarding packets in a VPLS using multi-homing PE routers configured in an “active-active” link topology. As described herein, a PE router receives a packet from a multi-homed VPLS customer site, and processes the packet to determine a portion of a MAC domain to which the packet corresponds. When the packet is determined to correspond to a portion associated with the PE router, the PE router forwards the packet to the destination in accordance with forwarding protocols executing on the PE router. When the packet is determined to correspond to a portion associated with a second PE router, the PE router forwards the packet to the second PE router via a pseudowire that is external to the VPLS domain, and the second PE router forwards the packet to the destination in accordance with forwarding protocols executing on the second PE router.

If the packet is not a routed packet, a search is performed in the MAC table to locate an entry in the MAC table that identifies an egress port for the packet.

Abstract: Some embodiments of the invention provide a robust scaling-out of network functionality by providing a software layer, called the network hypervisor, that sits between the network forwarding functions (i.e., the forwarding plane) and the network control interfaces (i.e., the control plane). The network hypervisor of some embodiments provides a logical abstraction of the network's forwarding functionality, so that network operators make their control decisions in terms of this abstraction, independent of the details of the underlying networking hardware. The network hypervisor of some embodiments may then “compile” commands placed against this abstraction into configurations of the underlying hardware. Accordingly, in some embodiments, there are two design challenges: (1) the choice of the network abstraction, and (2) the technology needed to compile the logical “abstract” controls into low-level configurations.

Abstract: A distributed switch may include a hierarchy with one or more levels of surrogate sub-switches (and surrogate bridge elements) that enable the distributed switch to scale bandwidth based on the size of the membership of a multicast group. Moreover, each surrogate may optimize the hierarchy according to one or more optimization criteria. For example, each surrogate in the hierarchy may have the necessary information to ensure that if the next surrogate in the hierarchy is unavailable, the data may be routed to a backup surrogate. The selected hierarchy may be further optimized by skipping surrogates (or a surrogate level) such that the data intended for a skipped surrogate is sent to a surrogate in a lower-level of the hierarchy. This may better utilize the connection interfaces in the transmitting sub-switches and eliminate any unnecessary surrogate-to-surrogate transfers.
