Handling of HTTP Video Streams
According to one embodiment, a network device examines content-type fields of a Hypertext Transfer Protocol (HTTP) response message in response to a request for a selected content type. Thereafter, the priority level and/or the quality of service (QoS) level of communications is modified during transmission of a data stream having the selected content type.
1 . A method of managing traffic to clients on a digital network comprising:
examining, at a network device, a Hypertext Transfer Protocol (HTTP) response message for a selected content type;
identifying, at the network device, a data stream with the selected content type; and
modifying, at the network device, the data stream upon determining that the data stream has the selected content type.
2 . The method of claim 1 , wherein the modifying of the data stream includes increasing a priority of the data stream.
3 . The method of claim 1 , wherein the change to the handling of the modifying of the data stream includes lowering a priority of the data stream.
4 . The method of claim 1 , wherein the modifying of the data stream includes dropping the data stream based on the data stream being the selected content type.
5 . The method of claim 1 , wherein the selected content type is a multipurpose Internet Mail Extensions (MIME) type indicating a video stream.
6 . The method of claim 1 , wherein the selected content type is Flash.
7 . The method of claim 1 , wherein the selected content type is Javascript.
8 . The method of claim 1 , wherein the identifying of the data stream and modifying the data stream is applied on a per-user basis.
9 . The method of claim 1 , wherein the network device is a switch, controller, or router.
10 . The method of claim 1 , wherein the network device is an access point (AP).
11 . The method of claim 1 , wherein the modifying of the data stream further includes increasing a Quality of Service (QoS) of the data stream.
12 . The method of claim 10 , wherein the examining of the HTTP response messages, the identifying of the data stream, and the modifying of the data stream are applied for a subset of clients in communications with.
13 . The method of claim 10 , wherein the examining of the HTTP response messages, the identifying of the data stream, and the modifying of the data stream are applied on a per-client basis for clients in communications with the AP.
14 . A non-transistory machine readable medium having a set of instructions stored in a memory which when executed on a network device which are part of a network, causes a set of operations to be performed comprising:
examining a Hypertext Transfer Protocol (HTTP) response message for a selected content type:
a data stream with the selected content type; and
modifying the data stream upon determining that the data stream has the selected content type.
15 . The machine readable medium of claim 14 where the network device is an access point (AP).
16 . A method comprising:
examining, at a network device, a Hypertext Transfer Protocol (HTTP) response message in response to a request for a selected content type; and
modifying, at the network device, one of a priority level and a quality of service (QoS) level of communications during transmission of a data stream having the selected content type.
17 . The method of claim 16 , wherein the modifying of the one of the priority level and the QoS level includes increasing the priority level of the communications for transmitting the data stream.
18 . The method of claim 16 , wherein the modifying of the one of the priority level and the QoS level includes lowering the priority level of the communications for transmitting the data stream.
20 . The method of claim 16 , wherein the modifying of the one of the priority level and the QoS level is performed on a per-user basis.
