A system of route target filtering includes an import filter receiving a plurality of routes having a next hop routing information. The import filter accepts a first subset of the routes according to an import target policy. The system further includes a re-export filter also receiving the plurality of routes. The re-export filter modifies the next hop information of a second subset of the routes, and distributes the modified routes.

System and method of virtual private network route target filtering

A system and method for topology constrained Quality of Service (QoS) provisioning between a plurality of sites in a Virtual Private Network (VPN) is disclosed. The method comprises enabling graphical definition of relationships between the plurality of sites of the VPN and enabling graphical definition of at least one QoS rule for at least one pair of sites of the plurality of sites of the VPN based at least in part on the defined relationship.

System and method for topology constrained QoS provisioning

A system and method for topology constrained routing policy provisioning between a plurality of sites in a Virtual Private Network (VPN) is disclosed. The method comprises enabling graphically defining of relationships between the plurality of sites of the VPN; and automatically generating at least one routing rule for each site of the VPN based at least in part on the defined relationship.

A method for allocating and resizing a link on a communication medium is provided. The utilization of an allocated link is monitored and an unused bandwidth thereof is determined. Upon request for allocation of a second link, at least a portion of the unused bandwidth is included in the bandwidth of the second link allocated. A network including two nodes and a communication medium terminated thereby is operable to provide a plurality of communication links and is operable to resize the bandwidth of the allocated links is provided. The network is operable to monitor the utilization of an allocated bandwidth of an allocated link and deallocate a part of the allocated bandwidth that is non-utilized by the allocated link. The deallocated bandwidth, or a portion thereof, may then be included in a bandwidth allocation made for allocation of an additional link.

System and method for resizing the physical link bandwidth based on utilization thereof

Methods and apparatus are provided for processing messages for access to information stored in an open directory. A Lightweight Directory Access Protocol (LDAP) LDAP Validation Proxy (LVP) is used to intercept LDAP request messages intended for the directory, validates the LDAP requests according to a schema description and optionally provides side-effects. The schema validation and LDAP message processing is modularized according to object classes representing the data stored in the directory and according to services provided. The schema is enforced by validating LDAP messages. This modularization provides a controlled message processing granularity and enables multi-threaded concurrent processing of multiple LDAP messages. The LVP has the capability of generating LDAP requests in processing LDAP messages. The LVP also intercepts and processes LDAP responses issued by a directory and intended for clients.
