Appl. No.:

10/103299

Inventors:

Anthony Walker - Newport Beach CA, US
Craig Barrack - Irvine CA, US

Assignee:

Zarlink Semiconductor V.N. Inc. - Irvine CA

International Classification:

H04J003/06

US Classification:

370/508000, 375/356000

Abstract:

A method of and apparatus for detecting drift between two clocks is presented. The apparatus comprises a hardware implementation of a clock drift evaluator. The evaluator monitors received packets associated with a data stream, and extracts a time stamp generated by a source clock from each packet. A difference d between the extracted time stamp and the local time is compared against a d_ref value to determine whether the packet was received early or late. On a prescribed schedule, the degree of late and early receipt of packets is compared against a tolerance level to determine whether a relative drift exists between the pacing of the source clock and the pacing of the local clock. The detection of drift between the two clocks provides support for service level guarantees in provisioning data streaming services in packet-switched environments.

US Classification:

370/389000

Abstract:

A method of context switchover continuity is disclosed in which a context is sent from a transmitting entity to a receiving entity. Initial first and second context state entries are maintained in respective tables at the transmitting entity and at the receiving entity. The initial first and second context state entries include context state information about the context. New reconfigured first and second context state entries are created at the transmitting entity and the receiving entity having reconfigured context state information. The new reconfigured first and second context state entries are activated so as to enable the sending of a reconfigured context from a transmitting entity to a receiving entity. A plurality of contexts are included, and each of the plurality of contexts has respective initial first and second context entries in the respective tables. The respective initial first and second context entries are active entries and the new reconfigured first and second context state entries are latent entries until the step of activating.

Abstract:

A cover for protecting a cellular phone comprising: a top edge; a bottom edge; side edges, where the side edges connect the top edge and bottom edge; an outer surface; and a plurality of tentacles, where said tentacles extend from the outer surface. During use the top edge, bottom edge and side edges extend over the outer edges of the cellular phone to provide suitable protection for the cellular phone.
