Abstract: A system and method for providing integrated secured and optimized packet messaging is described. A plurality of request packets staged in a packet queue from a requesting client and specifying content for retrieval from a destination server are categorized. The content is retrieved from the destination server. The retrieved content is optimized for at least one such request packet. The retrieved content is exchanged as secure content protected using a cipher negotiated with the requesting client for at least one such request packet.

Abstract: Systems and methods are described for supporting Quality of Service assurances for communication by and between software applications over a best-efforts networks. Characteristic signatures are generated and referenced to segregate traffic on the network into discrete flows. Traffic engineering protocols, such as MPLS, are used to generate discrete paths in the best-efforts network, and flows are routed on such paths based on pre-set policies. The state of individual paths and the network at large are continuously monitored in order to re-map flows on paths and maintain the QoS assurances.
