Service class ID for multimedia streams over IP networks

摘要

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.
