Appl. No.:

11/709512

Inventors:

Mohammed T. Shaikh - Fremont CA, US

International Classification:

H04L 12/28

US Classification:

370235, 370231

Abstract:

Negotiation of RSVP reservations prior to the setup of a call, rather than negotiating reservation parameters during the call. RSVP reservation parameters are negotiated prior to ringing a device, rather than after. In some embodiments, this is achieved by including information in the initial call signaling elements. This added information allows negotiation with each device in the proposed data path to determine, prior to ringing the terminating device in the data path, whether each of the devices can support the proposed data link.

US Classification:

370352, 370401, 370467, 379 9315, 709228

Abstract:

Methods and systems for optimizing interworking between various communication protocols are provided. The method comprises establishing a communication connection between a first endpoint and a second endpoint, wherein the first endpoint communicates over a first communication protocol and wherein the second endpoint communicates over a second communication protocol; and monitoring communication between the first and second endpoints such that communication messages that are transmitted by the first endpoint over the first communication protocol can be mapped to counterpart messages to be received by the second endpoint over the second communication protocol, and communication messages that are transmitted by the second endpoint over the second communication protocol can be mapped to counterpart messages received by the first endpoint over the first communication protocol.

Parameswaran Kumarasamy - San Jose CA, US
Jayesh Chokshi - Cupertino CA, US
Vinay Pande - San Jose CA, US

International Classification:

G06F 15/16

US Classification:

709230000

Abstract:

In accordance with at least one embodiment of the present invention, a communication apparatus includes a communication unit configured to send and receive messages on a network. Each message has a message header configured to include a plurality of header fields, where the message header includes a suppression header field that indicates a request to suppress at least one header field in at least one subsequently sent or received message. The communication apparatus is configured to establish a suppressed header field message exchange session with a peer on the network so that at least one subsequent message exchanged between the communication apparatus and the peer is free of at least one suppressible header field.

Appl. No.:

11/448280

Inventors:

Mohammed Taher Shaikh - Fremont CA, US
Viraj Raut - Santa Clara CA, US

Assignee:

Cisco Technology, Inc. - San Jose CA

International Classification:

H04L 12/28

US Classification:

370351

Abstract:

Techniques and systems for inter-working between different protocols are disclosed. In one embodiment, a protocol inter-working system can include: (i) a first server that can connect to a first gateway, where the first server and the first gateway can operate in a first protocol; (ii) a second server that can connect to a second gateway, where the second server and the second can operate in a second protocol; and (iii) a controller that can connect to the first and second gateways, where the controller can translate a first indicator in the first protocol to a second indicator in the second protocol. The first and second protocols can include H.323 and session initiation protocol (SIP), for example. The first and second indicators can each include a message waiting indicator (MWI), for example.

International Classification:

H01f 1000

US Classification:

427 36

Abstract:

Method of providing a substrate with a patterned metal layer disposed thereon, wherein a patterned metal mask is employed in conjunction with ion milling to form the pattern in the metal layer on the substrate. The metal mask as contemplated herein is made of a metallic masking mterial taken from the group consisting of vanadium, tantalum, titanium, and a titanium-tungsten alloy--vanadium being a preferred material because of its resistance to erosion or etching from ion milling coupled with its relatively fast etch rate in a plasma atmosphere. This method has particular application to magnetic bubble domain technology, wherein successive layers of a magnetically soft material, vanadium, and photoresist are deposited on a magnetic film capable of supporting magnetic bubble domain propagation. The layer of magnetically soft material is typically permalloy, and upon being patterned in a selected configuration, defines a bubble propagation path on the magnetic bubble-supporting film. The photoresist layer is selectively exposed to the predetermined pattern by a source of energy, such as an E-beam, X-ray or ultra violet light.
