Abstract: In one embodiment, the method includes determining, at a first network element, whether to turn on compression of a header for a packet transport protocol used for a communication flow between the first network element and a second network element. The determining is based on a type of the communication flow, and the packet transport protocol is a protocol for transport of packets between the first and second network elements. The method further includes sending a compression mode indictor to the second network element along with a context identifier. The compression mode indicator indicates the determination, and the context identifier for use in identifying the communication flow.

Abstract: A multiprocessor configuration includes a plurality of processing groups connected to form both a first and second communication path, and an interpath connection connecting the first and second communication paths. The first and second communication paths and the interpath connection provide allow communication between processors in different processing groups even if one processing group fails and, thus, creates a discontinuity in both the first and second communication paths. One or more processors in each processing group may be operable to perform fault recovery in response to a detected failure in another processing group.

Abstract: A cellular communications network providing multi-hyperband capability comprises a mobile switching center acting as a data administration and call control center for a plurality of cells, each cell divided into one or more sectors. A plurality of communications links connect the mobile switching center to associated cells. Each sector is capable supporting one or more hyperbands. Entities representing sector-specific data are differentiated from hyperband-specific entities. Thus, a sector-related message transmitted via the communications links comprises a cell and sector number key and a plurality of parameters related to the cell and sector number, and a hyperband-related message transmitted via the communications links comprises a hyperband key, wherein the hyperband key corresponds to one of the supported multiple hyperbands, and a plurality of parameters related to the hyperband corresponding to the hyperband key.

Abstract: A method allowing a plurality of resources allocators to allocate use of resources (e.g., processing resources) without communicating with each other. The resource allocators are independent of one another and allocate the resources based upon availability notifications from a plurality of resources. Availability of a resource is based upon a characteristic of the resource (e.g., resource occupancy) and may be determined by the resource comparing the characteristic to a threshold.
