US 2011/0235644 A1 · METHOD AND SYSTEM FOR TRANSPARENT LAN SERVICES IN A PACKET NETWORK

Abstract

A network apparatus includes a customer network portion having a customer premises equipment (CPE) bridge configured to connect to internal network entities of the customer network portion and to edge bridges of a provider network portion interconnecting separate customer network portions. The CPE bridge is configured to determine a transparent local area network service (TLS) for a packet received from one of the internal network entities based on a media access control (MAC) address of a destination of the packet in a different separate customer network portion. The CPE bridge is also configured to modify the packet to indicate the determined TLS, for the provider network portion to utilize to transmit the packet based on the determined TLS to a second CPE bridge associated with the destination, without the provider network utilizing the destination MAC address.

Claims10

Dependent claims

A packet processing device comprising:

a first memory device storing a forwarding information database that includes only addresses after forwarding state reduction, each said address aggregating many customer service instances, and
a second memory device storing a service instance storage database containing all customer service instances, storing an original un-reduced address for each.

Dependencies are inferred from the claim text.
