METHOD AND SYSTEM OF CACHE DISCOVERY IN A PEER-TO-PEER ENVIRONMENT
An approach is provided for cache discovery in a peer-to-peer system. A request is received from a peer node based on a network address assigned to a plurality of network caches, wherein the peer node is configured to operate in a peer-to-peer environment. In response to the request, a closest one of the network caches is determined based on a closest instance of a network address.
1 . A method comprising:
receiving a request from a peer node, configured to operate in a peer-to-peer environment, based on a network address assigned to a plurality of network caches;
in response to the request, determining a closest one of the network caches based on the network address.
2 . A method as recited in claim 1 , wherein the determination of the closest network cache is based on a routing protocol that utilizes the network address.
3 . A method as recited in claim 1 , further comprising:
designating the network caches to be accessible by a non-subscriber; and
generating a route announcement specifying routing information for accessing the network caches based on the designation.
4 . A method as recited in claim 1 , wherein the network address provides a one-to-many association, and the peer-to-peer environment is hybrid.
5 . A method as recited in claim 4 , wherein the network address is an Anycast address.
6 . A method as recited in claim 4 , wherein the network caches are maintained by one or more Internet Service Providers (ISPs).
7 . A computer-readable storage medium bearing instructions that are arranged, upon execution, to cause one or more processors to perform the method of claim 1 .
8 . An apparatus comprising:
a communication interface configured to receive a request from a peer node, configured to operate in a peer-to-peer environment, based on a network address assigned to a plurality of network caches; and
a processor coupled to the communication interface and configured to determine, in response to the request, a closest one of the network caches based on the network address.
9 . An apparatus as recited in claim 8 , wherein the determination of the closest network cache is based on a routing protocol that utilizes the network address.
10 . An apparatus as recited in claim 8 , wherein the processor is further configured to generate a route announcement specifying routing information for accessing the network caches based on determining whether the network caches are to be accessible by a non-subscriber.
11 . An apparatus as recited in claim 8 , wherein the network address provides a one-to-many association, and the peer-to-peer environment is hybrid.
12 . An apparatus as recited in claim 11 , wherein the network address is an Anycast address.
13 . An apparatus as recited in claim 11 , wherein the network caches are maintained by one or more Internet Service Providers (ISPs).
14 . A system comprising:
a plurality of network caches configured to store media objects, wherein the plurality of network caches is assigned a common network address; and
a router in communication with the network caches and configured to receive a request from a peer node based on the network address, wherein the router is configured to determine a closest one of the network caches based on the network address and to direct the request to the determined closest network cache.
15 . A system as recited in claim 14 , wherein the determination of the closest network cache is based on a routing protocol that utilizes the network address.
16 . A system as recited in claim 15 , wherein the determination of the closest network cache is further based on location of the request.
17 . A system as recited in claim 14 , wherein the router is further configured to generate a route announcement specifying routing information for accessing the network caches based on determining whether the network caches are to be accessible by a non-subscriber.
18 . A system as recited in claim 14 , wherein the network address provides a one-to-many association.
19 . A system as recited in claim 18 , wherein the network address is an Anycast address.
20 . A system as recited in claim 18 , wherein the network caches are maintained by one or more Internet Service Providers (ISPs).
