Abstract: A method and apparatus is disclosed herein for a resource allocation protocol. In one embodiment, the apparatus comprises a resource allocation engine to allocate physical resources to primary and redundant virtual infrastructures, wherein, when the resource allocation engine allocates virtual infrastructures, physical resources of redundant virtual infrastructures are shared across multiple primary virtual infrastructures.

Abstract: A method and apparatus is disclosed herein for live replication. In one embodiment, the method comprises replicating a source server to create a replica server, assigning a routable Internet Protocol (IP) address to the replica server; and migrating one or more, but not all, on-going connections from the source server to the replica server.

Abstract: A method and apparatus for layered rateless coding are described. In one embodiment, the method comprises dividing content into a plurality of content layers based on priority; expanding each layer into an encoded layer using an erasure code at a coding rate to produce a plurality of encoding layers, wherein the coding rate for each layer is set based on the priority and reduces as the priority of the content layers increases; concatenating a plurality of encoding layers produced by passing the plurality of layers through fixed rate precoders; and performing rateless encoding on the concatenated plurality of encoding layers to produce rateless encoding blocks.

Abstract: Wireless access efficiency is improved in a multi-hop, multiple-flow network by optimizing multi-flows over the entire network. This approach also benefits individual flows. These mechanisms apply joint routing and traffic-shaping techniques to multiple-flows at intermediate hops. Even though the routing and traffic-shaping techniques may adversely affect flows at some hops, when considered over multiple hops (for a given flow) and over multiple flows (for a given hop or number of hops), significant performance may be achieved for all flows. System performance is achieved by controlling the routing paths of multiple flows in a multi-hop, multi-flow wireless network, and applying traffic shaping in a systematic way, rather than relying on an opportunistic (i.e., randomly or independently optimized) approach. In a multi-hop environment, additional advantages of transparency to both the originating application (at the application layer) and terminating application (at the application layer) are achieved.

Abstract: An apparatus, a method, and a computer program product for effective communication routing of unicast and broadcast data traffic in wireless ad-hoc networks are presented. The routing technique separates the signaling and data transmission portions of a data frame such that the length of the signaling portion is independent of the length of the data portion. In the signaling portion, reservations are able to be performed and confirmed, while the data portion also includes a reservation confirmation portion which allows reservations made in during the signaling portion of the frame to be confirmed immediately prior to transmission of the data. In addition, the present invention also provides a mechanism for dynamically adjusting reservations.
