Data prioritization system and method therefor
A system and method of prioritizing data for use with a shared bandwidth communication network provides the benefit of prioritizing some data traffic over other data traffic. The prioritization may occur at least at a gateway to the shared bandwidth communication network. The prioritization may be implemented by selectively supplying data to clients such that some data traffic is prioritized over other data traffic. An interface may be provided to communicate data between one or more clients and the shared bandwidth communication network.
1. A system for prioritizing communication in a shared bandwidth communication network comprising:
an interface coupled to one or more clients via the shared bandwidth communication network, the interface configured to receive requests from the one or more clients for response by one or more network destinations and to forward responses to the one or more clients via the shared bandwidth communication network so that they are received at a first rate and order; and
a front end interposed between the interface and the one or more network destinations, the front end configured to receive the responses and forward the responses to the interface in accordance with a second rate and order, whereby the clients receive the responses at a rate and order controlled by the front end rather than the interface, wherein the front end is communicatively coupled to the one or more network destinations via an enhanced bandwidth network that has a first network protocol different from a second network protocol of the shared bandwidth communication network, the front end is further configured to convert the responses from the first network protocol to the second network protocol.
2. The system of claim 1 , wherein the one or more clients are one or more end user devices of the shared bandwidth communication network.
3. The system of claim 1 , wherein the front end is further configured to manipulate communication parameters selected from the group consisting of window size, window expansion rate, and window contraction rate to effectively prioritize certain of the responses over others of the responses.
4. The system of claim 1 , wherein the shared bandwidth communication system is coupled to the Internet to allow communication between the one or more clients and the Internet.
5. The system of claim 2 , wherein the front end is configured to provide different levels of service to the one or more clients based on one or more of content type, end user identity, end user history and session statistics.
6. The system of claim 1 , wherein the front end is further configured to prioritize the responses for forwarding through the interface.
7. The system of claim 1 , wherein the front end is further configured to cache at least one response and respond to a future request from the one or more clients by supplying the cached response.
8. The system of claim 7 , wherein the front end is configured to update the cached response in the cache prior to receiving the future request.
9. The system of claim 1 , wherein the front end is further configured to establish a priority for at least one response based on a packet type of the at least one response.
10. A method, relative to a communication system including an interface coupled to one or more clients via a shared bandwidth communication network, wherein the interface receives requests from the one or more clients for response by one or more network destinations and wherein the interface forwards responses to said one or more clients so that they are received in a first rate and order, the method comprising:
interposing a front end between the interface and the one or more network destinations, the front end configured to receive the responses and forward the responses to the interface in accordance with a second rate and order, whereby the clients receive said responses at a rate and order controlled by said front end rather than said interface, wherein the front end is further configured to receive the responses via an enhanced bandwidth network that has a first network protocol different from a second network protocol of the shared bandwidth communication network and convert the responses from the first network protocol to the second network protocol.
11. The method of claim 10 , wherein the one or more clients are one or more end user devices of the shared bandwidth communication network.
12. The method of claim 11 , wherein the front end is further configured to provide different levels of service to the one or more clients based on one or more of content type, end user identity, end user history and session statistics.
13. The method of claim 10 , wherein the front end is further configured to manipulate communication parameters selected from the group consisting of window size, window expansion rate, and window contraction rate to effectively prioritize certain of the responses over others of the responses.
14. The method of claim 10 , wherein the front end is further configured to cache at least one response and respond to a future request from the one or more clients by supplying the cached response.
15. A front end relative to a communication system including an interface coupled to one or more clients via a shared bandwidth communication network, wherein the interface receives requests from the one or more clients for response by one or more network destination and wherein the interface forwards responses to said one or more clients so that they are received in a first rate and order, the front end configured to receive said responses and forward said responses to said interface in accordance with a second rate and order, whereby said clients receive said responses at a rate and order controlled by said front end rather than said interface, and wherein the front end is further configured to receive the responses via an enhanced bandwidth network that has a first network protocol different from a second network protocol of the shared bandwidth communication network and convert the responses from the first network protocol to the second network protocol.
16. The front end of claim 15 , wherein the one or more clients are one or more end user devices of the shared bandwidth communication network.
17. The front end of claim 16 , wherein the front end is further configured to provide different levels of service to the one or more clients based on one or more of content type, end user identity, end user history and session statistics.
18. The front end of claim 15 , wherein the front end is further configured to manipulate communication parameters selected from the group consisting of window size, window expansion rate, and window contraction rate to effectively prioritize certain of the responses over others of the responses.
19. The front end of claim 15 , wherein the front end is further configured to cache at least one response and respond to a future request from the one or more clients by supplying the cached response.
