The method additionally includes adjusting the bandwidth used by the first endpoint to a second bandwidth that is different than the first bandwidth based on a second priority level that is different than the first priority level. | 07-28-2011 |
20110261835 | EXECUTING AND SUPPORTING A MULTIPLE BANDWIDTH RESERVATION REQUEST - In one embodiment, a method includes obtaining a first message that includes at least a first bandwidth request that specifies a first bandwidth and a second bandwidth request that specifies a second bandwidth. The first bandwidth is a preferential bandwidth. The method also includes determining whether the first bandwidth may be allocated, and storing the first bandwidth and the second bandwidth in a stored reservation state if the first bandwidth may be allocated. If the first bandwidth may not be allocated, the method includes determining whether the second bandwidth may be allocated. The second bandwidth in the stored reservation state if it is determined that the second bandwidth may be allocated. In one embodiment, if the second bandwidth may be allocated, the first bandwidth is removed during process prior to sending the message to a subsequent node upstream. | 10-27-2011 |
20110299553 | Technique for Reducing Resources Allocated to an Existing Reservation in a Data Network - A technique that allows existing reservations to be partially preempted by higher-priority reservations. An intermediate node receives a request to reserve resources for the higher-priority reservation. The higher priority entitles the reservation to acquire resources allocated to existing lower priority reservations, if necessary. If sufficient unallocated resources are not available on the preempting system to accommodate the higher-priority reservation, an error message is generated and forwarded by the intermediate node towards a receiver associated with the reservation that is to be partially preempted. The error message contains an error code and an amount of resources available on the intermediate node. The receiver processes the error message including selecting a reservation to be torn down, tearing down the selected reservation and re-reserving resources for remaining reservations, as necessary. | 12-08-2011 |
20120005351 | METHOD AND APPARATUS FOR TRANSMITTING AN APPLICATION IDENTIFIER ACROSS APPLICATION ELEMENTS - In one embodiment, a method includes generating a Session Description Protocol (SDP) construct, the SDP construct being arranged to be included in a first signaling flow. The method also includes providing an attribute in the SDP construct. The attribute identifies an application type associated with a first traffic flow. Finally, the SDP construct is forwarded on the first signaling flow. | 01-05-2012 |
20120106326 | SYNCHRONIZED BANDWIDTH RESERVATIONS FOR REAL-TIME COMMUNICATIONS - A method of initiating a communication session includes transmitting, using a call signaling protocol, a call invitation from a first node over a network for receipt by a second node. The call invitation comprises a list of one or more codecs available to the first node for use when transmitting data over a network. The call invitation additionally comprises a traffic specification associated with each of the one or more codecs. The traffic specification associated with each of the one or mode codecs comprises a plurality of bandwidth attributes that describe the flow of data when transmitting data using each of the one or more codecs. | 05-03-2012 |
20130114426 | METHOD AND APPARATUS FOR POOLING BANDWIDTH ACROSS DISPARATE BANDWIDTH RESERVATIONS - In one embodiment, a method includes obtaining a message associated with a data flow that includes a first indicator that identifies an amount of requested pool bandwidth and a second indicator that identifies a pool with which the data flow is associated. The pool is associated with a plurality of data flows that includes the data flow.

Finally, the method includes reserving approximately the amount of requested bandwidth when it is determined that reserving the amount of requested bandwidth would not cause the overall bandwidth allocation to exceed the maximum pool bandwidth allocation. Reserving approximately the amount of requested bandwidth includes increasing the overall bandwidth allocation by the amount of requested bandwidth. | 05-09-2013 |
