Abstract
In one embodiment, a reservation proxy monitors for received connectivity check messages or beginning-of-media-flow indication messages. When either type of message is observed, the reservation proxy requests resource allocation for a media flow associated with the received message. The amount of resource allocation requested may be coordinated by exchanging messages with a call controller or policy server for one of the endpoints of the media flow, or the amount of resource allocation may be identified within the received message.
Claims20
An apparatus, comprising:
- a processing device;
- and
- a memory coupled to the processing device comprising instructions executable by the processing device, the processing device operable when executing the instructions to:
- monitor for a message having a predetermined message type that corresponds to a beginning of a media flow;
- identify a priority value that corresponds to the media flow;
- receive packets for the media flow, the packets having an indicated priority;
- replace the indicated priority with the identified priority value;
- and
- forward a representation of the packets that includes the identified priority value.
An apparatus, comprising:
- a processing device;
- and
- a memory coupled to the processing device comprising instructions executable by the processing device, the processing device operable when executing the instructions to:
- monitor for a message having a predetermined message type that indicates a beginning of a media flow;
- identify a resource requirement or priority value that corresponds to the media flow in response to detecting the message;
- when the resource requirement is identified, request reservation of network resources for the media flow according to the identified resource requirement;
- and
- when the priority value is identified, format received packets corresponding to the media flow using the identified priority value before forwarding the formatted packets from a network device to a remote device.
A method, comprising:
- monitoring for a message having a predetermined message type that corresponds to a beginning of a media flow;
- identifying a priority value that corresponds to the media flow;
- receiving packets for the media flow, the packets having an indicated priority;
- checking if the indicated priority is different than a priority represented by the identified priority value;
- formatting the indicated priority according to the identified priority value when the indicated priority is different than the identified priority value according to said checking;
- and
- forwarding a representation of the packets that includes the formatted priority.
