Terminating connections and selecting target source devices for resource requests

Abstract

A device receives, from a client device, a request for a resource, and accesses a table that includes one or more items of information. The device compares information provided in the request to the one or more items of information provided in the table, and terminates a connection for the request at the device when the information provided in the request matches at least one of the one or more items of information provided in the table. The device forwards the request to a network when the connection is not terminated at the device, and selects a target device for the resource when the connection is terminated at the device.

   a processor, coupled to the memory, to:
 receive, from the network device, a request for a resource; 
 select, based on one or more of the local cache information, the resource information, or the network information, a target device that includes the resource,
 the target device including one of the plurality of server devices or the local cache; and 
 
 provide, to the network device, information identifying the target device. 
   
     
     
         33 . The computing device of  claim 32 , where the target device is selected based on one or more of:
 a bandwidth of the network,   costs associated with the network,   a load provided on the network, or   a physical location of the target device in relation to a client device requesting the resource.   
     
     
         34 . The computing device of  claim 32 , where the request includes a domain name and a uniform resource locator (URL) associated with the resource and the processor is further to:
 select the target device for the resource based on the domain name and the URL.   
     
     
         35 . The computing device of  claim 32 , where the target device includes a device associated with a federated service provider network that provides resources to the network in case of failure of the network or components of the network. 
     
     
         36 . The computing device of  claim 32 , where the request includes information identifying at least one of:
