Managing VLAN traffic in a multiport network node using customer-specific identifiers
First Claim
1. A method for managing traffic in a multiport network node comprising:
- establishing a customer-specific virtual local area network (VLAN), wherein the customer-specific VLAN specifies ports that are included in said customer-specific VLAN and wherein the customer-specific VLAN is identified by a customer-specific VLAN identifier (ID) that is a combination of a VLAN ID and a customer ID;
mapping traffic to said customer-specific VLAN; and
broadcasting said traffic to ports that are included in said customer-specific VLAN.

Abstract
A technique for managing traffic in a multiport network node involves establishing customer-specific VLANs within the multiport network node that are identified by a combination of a VLAN ID and a customer ID. Traffic received at the multiport network node is mapped to a customer-specific VLAN and then broadcast to ports that are included in the customer-specific VLAN. Because customer-specific VLANs are identified by a combination of a VLAN ID and customer ID, a service provider can establish and maintain private broadcast domains on a per-customer ID basis. This enables the service provider to expand the number of unique VLAN IDs within the Service Provider Edge Device beyond the 4,096 limitation set by the IEEE 802.1Q standard while maintaining interoperability with the IEEE 802.1Q standard for incoming and outgoing traffic.

9. A method for managing traffic in a multiport network node comprising:
-
receiving traffic at said multiport network node; identifying a virtual local area network (VLAN) identifier (ID) to which said traffic belongs; mapping said traffic to a customer ID; and transmitting said traffic to ports in a customer-specific domain wherein said customer-specific broadcast domain is identified by the customer-specific VLAN identifier (ID) that is a combination of said VLAN ID and said customer ID. - View Dependent Claims (10, 11, 12, 14, 15, 16, 17)
