Service class ID for multimedia streams over IP networks
Systems and methods can operable to provide a service class identifier field for packets transmitted over a network. Systems can include an interface, a control device and a transmitter. The interface can receive a data packet comprising a packet header and payload, and the packet header can include a differentiated services code point field. The control device can identify one or more network traffic parameters of a data stream associated with the received data packet and modify the data packet to include one or more service class identifier codes associated with the data packet. The transmitter can forward the modified data packet to a network device suited to interpret the service class identifier codes through one or more intermediate routers.
1. A computer-implemented method, comprising:
receiving a data packet at a first network device, the data packet comprising a packet header and payload, the packet header including a differentiated services code point field;
identifying one or more network congestion parameters of a network associated with the first network device;
modifying the differentiated services code point field within the data packet to include service class identifier codes based on the identified one or more network congestion parameters, the service class identifier codes identifying quality of service settings tailored to applications operable to interpret the service class identifier codes;
forwarding the modified data packet to a second network device suited to interpret the service class identifier codes through one or more intermediate routers that are not suited to interpret the service class identifier codes, wherein the service class identifier codes comprise: a hand-held definition video setting using a 1 Mbps data rate; a standard definition video setting using a 3 Mbps data rate; a high definition video setting using an 8 Mbps data rate; and, a three-dimensional high definition video setting using a 12 Mbps data rate.
2. The method of claim 1 , wherein the service class identifier codes comprise control for one or more of bandwidth management, priority, latency, or scheduling algorithms.
3. The method of claim 1 , wherein the intermediate routers comprise routers on a public network.
4. The method of claim 3 , wherein the first and second network devices comprise one or more of a cable modem termination system, set top box, video server, cable modem, embedded multimedia terminal adapter, or combinations thereof.
5. The method of claim 3 , wherein the first and second network devices are operable to use the differentiated services code point field to provide signaling to change one or more transmission parameters associated with a data stream.
6. A system, comprising:
an interface operable to receive a data packet, the data packet comprising a packet header and payload, the packet header including a differentiated services code point field;
a control device operable to identify one or more network traffic parameters of a data stream associated with the received data packet;
the control device being further operable to produce a modified data packet modifying the received data packet to include one or more service class identifier codes, the one or more service class identifier code being selected based on the identified one or more network traffic parameters;
a transmitter operable to forward the modified data packet to a network device suited to interpret the service class identifier codes, the modified data packet being transmitted through one or more intermediate routers that are not suited to interpret the service class identifier codes, wherein the service class identifier codes comprise: a hand-held definition video setting using a 1 Mbps data rate; a standard definition video setting using a 3 Mbps data rate; a high definition video setting using an 8 Mbps data rate; and, a three-dimensional high definition video setting using a 12 Mbps data rate.
7. The system of claim 6 , wherein the service class identifier codes comprise control for one or more of bandwidth management, priority, latency, or scheduling algorithms.
8. The system of claim 6 , wherein the intermediate routers comprise routers on a public network.
9. The system of claim 8 , wherein the system comprises one or more of a cable modem termination system, set top box, video server, cable modem, embedded multimedia terminal adapter, or combinations thereof.
10. The system of claim 8 , wherein the system is operable to use the differentiated services code point field to provide signaling to change one or more transmission parameters associated with a data stream.
11. The system of claim 6 , wherein the service class identifier codes identify quality of service settings tailored to applications operating on a receiving network device operable to interpret the service class identifier codes.
12. One or more non-transitory computer readable media comprising program code operable to be executed by a processor and upon execution causing the processor to control one or more modules operable to:
receive a data packet, the data packet comprising a packet header and payload, and the packet header including a differentiated services code point field;
identify one or more data transmission parameters of a data stream associated with the received data packet, the data transmission parameters including at least one network congestion parameter;
modify the differentiated services code point field to include a service class identifier code based on the identified at least one network congestion parameter; and
forward the modified data packet to a network device suited to interpret the service class identifier codes through one or more intermediate routers that are not suited to interpret the service class identifier codes, wherein the service class identifier codes comprise: a hand-held definition video setting using a 1 Mbps data rate; a standard definition video setting using a 3 Mbps data rate; a high definition video setting using an 8 Mbps data rate; and, a three-dimensional high definition video setting using a 12 Mbps data rate.
13. The one or more computer readable media of claim 12 , wherein the service class identifier codes comprise control for one or more of bandwidth management, priority, latency, or scheduling algorithms.
14. The one or more computer readable media of claim 12 , wherein the intermediate routers comprise routers on a public network.
15. The one or more computer readable media of claim 14 , wherein the network device comprises one or more of a cable modem termination system, set top box, video server, cable modem, embedded multimedia terminal adapter, or combinations thereof.
16. The one or more computer readable media of claim 14 , wherein network devices are operable to use the differentiated services code point field to provide signaling to change the one or more transmission parameters associated with the data stream.
17. The one or more computer readable media of claim 12 , wherein the service class identifier codes identifying quality of service settings tailored to applications operable to interpret the service class identifier codes.
