Dedicated shared byte cache
View Patent ↗The present invention relates to methods, apparatus, and systems for providing peer-to-peer network acceleration. The system includes a content server configured to transfer content based on received requests for content. The system further includes a proxy server coupled with the content server. The proxy server is configured to receive content from the content server and to forward the received content. Furthermore, the system includes client systems coupled with the proxy server. The client systems each include a personal byte cache and are configured to receive content from the proxy server, to store content in the personal byte caches, to synchronize the personal byte caches with each of the plurality of client system's portions of a shared byte cache, and to retrieve content from the shared byte cache.
1. A system for implementing a dedicated shared byte cache, the system comprising:
a gateway in communication with a content server, the content server configured to transfer content based on received requests for content, the gateway including a gateway accelerator module, wherein the gateway accelerator module includes a proxy server, the proxy server configured to receive content from the content server and to forward the content;
a satellite in communication with the gateway, the satellite configured to transmit the received content;
a subscriber terminal in communication with the satellite, the subscriber terminal configured to the content; and
a plurality of client systems in communication with the subscriber terminal, the plurality of client systems each including a personal byte cache and configured to receive the content from the proxy server, to store the content in the personal byte caches, to synchronize the personal byte caches with each of the plurality of client system's portions of a shared byte cache at a dedicated shared byte cache server that is coupled to each of the plurality of client systems, and to retrieve the content from the shared byte cache.
2. A system for implementing a dedicated shared byte cache as in claim 1 , wherein a request for content comprises identifying whether a sequence of bytes associated with content is stored in the dedicated shared byte cache server, and requesting the sequence of bytes from the dedicated shared byte cache server.
3. A non-transitory machine-readable medium having sets of instructions stored thereon which, when executed by a machine, cause the machine to:
generate, at a plurality of client systems, requests for content;
communicate, from the plurality of client systems to at least one content server via at a proxy server, the requests for the content;
receive the content requested by each of the plurality of client systems at the corresponding client system;
store, within a personal byte cache associated with each of the plurality of client systems, the requested content; and
synchronize each of the personal byte caches with a shared byte cache at a dedicated shared byte cache server coupled to each of the plurality of client systems, wherein each of the plurality of client systems is apportioned a portion of the shared byte cache.
4. A machine-readable medium as in claim 3 , wherein the sets of instruction, when executed by the machine, further cause the machine to:
receive, at the dedicated shared byte cache server, content from a first client system of the plurality of client systems;
store the content in the shared byte cache,
receive a request from a second client system that includes a byte range in the cache that is associated with the first client system;
retrieve a sequence of bytes identified by the byte range from the shared byte cache in response to the request from the second client system; and
retrieve, by the second client system, the sequence of bytes from the shared byte cache.
5. A machine-readable medium as in claim 3 , wherein the sets of instruction, when executed by the machine, further cause the machine to, in response to the proxy server transferring content to the plurality of client systems, store, at the proxy server, a record for each of the plurality of client systems of the content stored within the personal byte caches.
6. A method comprising:
generating, at a plurality of client systems, requests for content;
communicating, from the plurality of client systems to at least one content server via at a proxy server, the requests for the content;
receiving the content requested by each of the plurality of client systems at the corresponding client system;
storing, within a personal byte cache associated with each of the plurality of client systems, the content; and
synchronizing each of the personal byte caches with a shared byte cache at a dedicated shared byte cache server coupled to each of the plurality of client systems, wherein each of the plurality of client systems is apportioned a portion of the shared byte cache.
7. The method of claim 6 further comprising:
receiving, at the dedicated shared byte cache server, at least a portion of the content from a first client system of the plurality of client systems;
storing the portion of the content in the shared byte cache,
receiving a request from a second client system that includes a byte range in the cache that is associated with the first client system;
retrieving a sequence of bytes identified by the byte range from the shared byte cache in response to the request from the second client system; and
receiving, by the second client system, the sequence of bytes from the shared byte cache.
8. The method of claim 6 further comprising, in response to the proxy server transferring content to the plurality of client systems, storing, at the proxy server, a record for each of the plurality of client systems of the content stored within the personal byte caches.
