A system operable to: receive a request for an application unit from a first device; generating a key for the application unit; look up segment cache indices corresponding to the application unit, according to the key; and determine whether the segment cache indices are available. Where the segment cache indices are available, the system may retrieve a segment cache using the segment cache indices; and then retrieve the application unit using the retrieved segment cache. Otherwise, where the segment cache indices are not available, the system may communicate the request to a second device to receive a response from the second device including the segment indices. Further, the system may receive the response from the second device; store a segment index sequence for the application unit in an application optimizer cache based on the response; and retrieve the application unit via the segment index sequence.

A system and method collects information for VPN traffic from non edge routers that are coupled to edge routers and identifies the path the traffic took and the customer corresponding to the VPN. The system and method also identifies the ingress router coupled to the non edge router from which the traffic was collected. The system and method may assign identifiers to route targets.

System and method for identifying an ingress router of a flow when no IP address is associated with the interface from which the flow was received

A method and apparatus for transparently transforming a multicast stream is provided. The method includes transforming the multicast stream in a content engine. The multicast stream has a first bandwidth. The content engine receives a request for the multicast stream from a multicast receiver with a second bandwidth availability. Thereafter, the content engine transforms the multicast stream to a multicast stream with a third bandwidth. The third bandwidth is less than or equal to the second bandwidth. The transformed multicast stream is sent to the multicast receiver.

System and method for identifying VPN traffic paths and linking VPN traffic and paths to VPN customers of a provider

In one embodiment, an optimizing device is used to suppress transmission of redundant data over networks. The first optimizing device receives information regarding associated optimizing devices associated with a second optimizing device. The information regarding the associated optimizing devices is received from the second optimizing device. Moreover, the first optimizing device receives information regarding indices identifying redundant data. The redundant data comprises data transmitted by the second optimizing device to the associated optimizing devices. The information regarding the indices identifying the redundant data is received from the second optimizing device.
