Multistage prioritization of packets within a session over internet protocol (SOIP) network
View Patent ↗A method includes receiving, at a first endpoint, session data associated with a first Internet Protocol (IP) packet. The IP packet is associated with a session within a Session over Internet Protocol (SoIP) network and the session is associated with a call. An instruction, based on the session data, is sent from the first endpoint to a second endpoint. The instruction is configured to trigger the second endpoint to modify a priority indicator associated with at least one of the first IP packet or a second IP packet associated with the call.
1. A method, comprising:
receiving, at a first endpoint, session data associated with a first Internet Protocol (IP) packet, the first IP packet being associated with a session within a Session over Internet Protocol (SoIP) network, the session being associated with a call;
identifying, in a priority database accessed by the first endpoint, a transmission priority value associated with the first IP packet; and
sending an instruction from the first endpoint to a second endpoint, the instruction being based on the session data, the instruction being configured to trigger the second endpoint to modify, based on the transmission priority value, a priority indicator associated with a second IP packet associated with the call, wherein the first endpoint and the second endpoint are each configured to transmit signaling packets and media-content packets, wherein the second endpoint does not have access to the priority database and is not configured to modify the priority indicator associated with the second IP packet until the instruction is received.
2. The method of claim 1 , wherein the first IP packet is at least one of a signaling packet or a media-content packet, the signaling packet includes protocol language used to establish the session.
3. The method of claim 1 , wherein the second IP packet is at least one of a signaling packet or a media-content packet, the signaling packet includes protocol language used to establish the session.
4. The method of claim 1 , wherein the instruction is a priority-modification instruction.
5. The method of claim 1 , further comprising receiving, at the first endpoint, session data associated with a third IP packet, the instruction being based on the session data associated with the third IP packet.
6. The method of claim 1 , further comprising receiving the second IP packet from the second endpoint via a connection associated with the session.
7. The method of claim 1 , wherein the session is a first session, the second endpoint transmits the at least one of the first IP packet or the second IP packet via a connection associated with a second session.
8. The method of claim 1 , wherein the session data is at least one of a layer-3 session-layer parameter, a layer-5 session-layer parameter, or an extrinsic parameter.
9. The method of claim 1 , wherein the first endpoint is a session controller, the session data is associated with at least one of a source endpoint or a destination endpoint.
10. The method of claim 1 , wherein the second endpoint is at least one of a session controller, a source endpoint, or a destination endpoint.
11. The method of claim 1 , wherein the session data indicates a status of at least one of a source endpoint or a destination endpoint.
12. The method of claim 1 , wherein the instruction includes a threshold condition, the second endpoint modifies the priority indicator in response to the threshold condition being satisfied.
13. A method, comprising:
receiving, at a first endpoint, a priority-modification instruction defined at a second endpoint, wherein the priority-modification instruction is defined based on session data associated with a first Internet Protocol (IP) packet of a call in a Session over Internet Protocol (SoIP) network, wherein the second endpoint is configured to access a priority database to identify a transmission priority value associated with the first IP packet; and
in response to receiving the priority-modification instruction, modifying, based on the transmission priority value, a priority indicator associated with a second IP packet associated with the call at the first endpoint, the second IP packet being transmitted over the SoIP network based on the priority indicator, wherein the first endpoint and the second endpoint are each configured to transmit signaling packets and media-content packets, and wherein the first endpoint does not have access to the priority database and is not configured to modify the priority indicator associated with the second IP packet until the priority-modification instruction is received.
14. The method of claim 13 , wherein the priority-modification instruction includes a threshold condition, the modifying being based on the threshold condition.
15. The method of claim 13 , further comprising receiving session data associated with the IP packet, the modifying being based on the session data.
16. The method of claim 13 , wherein the IP packet is a first IP packet, the priority-modification instruction is based on session data associated with a second IP packet.
17. The method of claim 13 , wherein the IP packet is at least one of a media-content packet or a signaling packet.
18. The method of claim 13 , wherein the second endpoint is a session controller.
19. The method of claim 13 , wherein the first endpoint is at least one of a session controller, a source endpoint, or a destination endpoint.
20. The method of claim 13 , wherein the priority-modification instruction is based on session data, the session data is associated with at least one of a source endpoint or a destination endpoint.
21. The method of claim 13 , wherein the priority-modification instruction is defined based on session data, the session data includes a value of at least one of a session layer parameter or an extrinsic parameter.
22. An apparatus, comprising:
a processor configured to receive session data associated with a first Internet Protocol (IP) packet, the first IP packet being associated with a session within a Session over Internet Protocol (SoIP) network, the processor being configured to define a priority-modification instruction based on the session data, the session being associated with a call, wherein the processor is configured to access a priority database to identify a transmission priority value associated with the first IP packet; and
an output port configured to send the priority-modification instruction to an endpoint, wherein the priority-modification instruction triggers the endpoint to modify, based on the transmission priority value, a priority indicator of a second IP packet associated with the call, and wherein the output port is configured to send both signaling packets and media-content packets, wherein the endpoint does not have access to the priority database and is not configured to modify the priority indicator of the second IP packet until the priority-modification instruction is received.
23. The apparatus of claim 22 , wherein the IP packet is at least one of a media-content packet or a signaling packet.
24. The apparatus of claim 22 , wherein the session data includes at least one of a value of a layer-3 session-layer parameter, a layer-5 session-layer parameter, or an extrinsic parameter.
25. The apparatus of claim 22 , wherein the endpoint is at least one of a session controller, a source endpoint, or a destination endpoint.
26. The apparatus of claim 22 , wherein the endpoint is configured to modify a priority indicator associated with at least one of a media-content packet or a signaling packet in response to the priority-modification instruction.
