An apparatus and system are disclosed for reducing network traffic using a shared network response cache. A request filter module intercepts a network request to prevent the network request from entering a data network. The network request is sent by a client and is intended for one or more recipients on the data network. A cache check module checks a shared response cache for an entry matching the network request. A local response module sends a local response to the client in response to an entry in the shared response cache matching the network request. The local response satisfies the network request based on information from the matching entry in the shared response cache.

Shared network response cache

A method is disclosed for reducing network traffic using a shared network response cache. The method intercepts a network request to prevent the network request from entering a data network. The network request is sent by a client and is intended for one or more recipients on the data network. The method checks a shared response cache for an entry matching the network request. The method sends a local response to the client in response to an entry in the shared response cache matching the network request. The local response satisfies the network request based on information from the matching entry in the shared response cache.

Mechanisms are provided for resolving a domain name. The mechanisms send a request, from a resolver executing on the data processing system, to a name server requesting a resolution of a domain name into an address. A response to the request is received that includes a local address. The local address has a scope that is local to a site and is not global in scope. A determination is made as to whether the local address corresponds to a domain associated with the resolver. Communications are then performed with a device corresponding to the domain name using the local address in response to a determination that the local address corresponds to a domain associated with the resolver.

Using unique local unicast addresses in a global domain name server

Mechanisms are provided for assigning addresses for use in communications between computing devices. With these mechanisms, a centralized domain name registrar server assigns a unique global identifier to a domain of a site such that the unique global identifier uniquely identifies the domain. The unique global identifier is received in a data processing system from the centralized domain name registrar server. The site is divided into a plurality of sub-domains and a unique sub-domain identifier is assigned to each sub-domain in the site such that the unique sub-domain identifier uniquely identifies a corresponding sub-domain in the site. The global identifier for the domain of the site and the sub-domain identifiers of the sub-domains in the plurality of sub-domains are provided by the data processing system to routers of the site for use in associating addresses with devices of the site.
