Multiple non-conflicting actions associated with filter rules may be located and applied to a packet using a single ACL lookup by causing action records to be created from ACEs in the ACL, and then causing the ACL lookup to return the action record rather than any one particular ACE. Radix tables may be created to enable a search engine to quickly locate the appropriate action record based on a particular set of attributes associated with the incoming packet. The action record can contain multiple actions taken from multiple ACEs that apply to the particular packet. By grouping all the actions into an action record, and then searching for an action record that applies to the packet, it is possible to apply all non-conflicting actions to the packet regardless of the number of ACEs that are used to specify those actions. Since all the actions are located together, the actions of all ACEs may be applied to a packet using a single ACL lookup.

Method and apparatus for implementing filter rules in a network element

A system, device, and method for managing connection establishment and related services in an optical communication system uses an optical service agent to manage the connection establishment and related services on behalf of a user. The optical service agent may negotiate various connection and connection-related services, model connections, reserve communication services, establish connections on behalf of the user, and aggregate multiple optical communication paths over a connection, to name but a few. The optical service agent may interact with an optical communication network and/or various peer users in order to obtain and reserve communication services.

A system, device, and method for distributing routing information in an optical virtual private network establishes an initial bootstrap topology and distributes the routing information over the initial bootstrap topology. Each node establishes a communication connection to one and only one lower priority peer node if such a lower priority peer node exists. If more than one lower priority peer nodes exist, then one of the lower priority peer nodes is selected and the communication connection is established to the selected lower priority peer node.
