Abstract
A method includes receiving a request for an edge cache address, and comparing a requestor address to an anycast group. The method can further include providing an anycast edge cache address when the requestor address is in the anycast group. Alternatively, the method can further include determining an optimal cache server, and providing a unicast address of the optimal cache server when the requestor address is not in the anycast group.
Claims20
A system comprising:
- a memory that stores instructions;
- and
- a processor that executes the instructions to perform operations, the operations comprising:
- causing traffic associated with a request from an anycast group to enter a network at a same router when the anycast group is in a stable network;
- and
- causing the traffic to enter the network at multiple routers when the anycast group is in an unstable network.
A method, comprising:
- facilitating, by utilizing instructions from a memory that are executed by a processor, entry of traffic associated with a request from an anycast group into a network at a same router when the anycast group is in a stable network;
- and
- facilitating entry of the traffic into the network at multiple routers when the anycast group is in an unstable network.
A non-transitory computer-readable device comprising instructions, which, when loaded and executed by a processor, cause the processor to perform operations, the operations comprising:
- facilitating entry of traffic associated with a request from an anycast group into a network at a same router when the anycast group is in a stable network;
- and
- facilitating entry of the traffic into the network at multiple routers when the anycast group is in an unstable network.
