Abstract: The method, apparatus and system of detecting whether a router is compromised and configured to place malicious packets onto the network are disclosed. In one embodiment, a method for detecting a malicious router includes performing hash on a current ingress packet received via the network packet payload to generate ingress packet hash values. Further, includes performing hash on current egress packet that is associated with the current ingress packet to generate egress packet hash values. The generated ingress packet hash values and the egress packet hash values are then compared. Then the router is checked to determine whether it is potentially compromised and configured to place the malicious packets based on the outcome of the comparison.

Abstract: A method and apparatus for detecting predefined signatures in packet payload is disclosed. In one embodiment, a method of string matching in a network packet payload includes performing hash on a current search string received in the network packet payload to generate respective search string hash values, storing the search string hash values in a hash buffer, performing rehash using the search string hash values to generate an associated search string rehashed value, performing a parallel search of the search string rehashed value against Content Addressable Memory (CAM) entries to determine if the search string rehashed value matches with one of the CAM entries, and identifying the current search string in the network packet payload as a match with one of the CAM entries based on the outcome of performing the parallel search.

Abstract: The embodiments described herein provide a method, program and computing network for processing a content request received via a computing network. The method comprises the steps of receiving an incoming request for content from a remote computing device, determining the content type requested by the incoming request and delivering the request to one of a plurality of servers according to the determined content request type.

Abstract: Data-type-based spanning tree reconfiguration includes determining volumes for one or more types of data transmitted in information flows in an existing spanning tree in a network. The spanning tree is reconfigured based on one or more of the volumes and the types of data transmitted in the flows.

Abstract: Load-aware spanning tree reconfiguration includes determining volumes for information flows in an existing spanning tree in a network. The spanning tree is reconfigured based on the volumes to provide higher-volume information flows with shorter paths in the reconfigured spanning tree.
