    Abstract: Lookup requests received by a domain name service (DNS) are processed based on the actual location of data associated with a requested content page rather than a domain mapping of IP addresses. A DNS server which receives a request initiates a query for the location of user data associated with the request based on an object handle contained in a domain name of the request. The location data is used to construct an IP address which is provided in response to the IP lookup request received by the DNS server. The DNS system may be used to provide IP addresses for a scaled web-based networking service, alternate versions of a service and a service implementing rolling upgrades.

    Abstract translation: 基于与所请求的内容页面相关联的数据的实际位置而不是IP地址的域映射来处理由域名服务（DNS）接收到的查找请求。 接收请求的DNS服务器基于包含在请求的域名中的对象句柄来发起与请求相关联的用户数据的位置的查询。 位置数据用于构建响应于DNS服务器接收的IP查询请求而提供的IP地址。 DNS系统可用于为缩放的基于网络的网络服务，服务的替代版本和实施滚动升级的服务提供IP地址。

    Abstract: A dynamic selection of a communications link between a storage controller and one of a plurality of storage servers is provided so as to enhance the performance of the storage system. The storage system includes a plurality of storage devices, a corresponding plurality of virtual storage controllers coupled to the storage devices and a virtual storage controller. The virtual storage controller includes a host interface, a server interface, a stored table and a processing unit. The stored table includes a list identifying the active links between the server interface and each virtual storage server and, for each active link, a corresponding performance value. The processing unit is programmed to receive from a host a request for a storage operation on selected data, determine which active link has the most favorable performance value and direct that the requested storage operation be performed by the virtual storage server coupled to the virtual storage controller over the active link having the most favorable performance value.

    Abstract: The present disclosure is directed to a system and method of selecting a virtual private network access server. In a particular embodiment, the method includes receiving a request from a client device to access a network resource via a virtual private network (VPN). The method also includes sending operational data related to each of a plurality of VPN access servers to the client device. The method also includes receiving a selection of one of the plurality of VPN access servers from the client device and communicatively connecting the client device with the selected one of the VPN access servers.

    Abstract: A router device and a cut-through path control method capable of carrying out the load balancing at an intermediate router device which actually has a multi-path information, without requiring a special processing at the edge router are disclosed. At a router device at which multi-path exists, one router among a plurality of routers that can possibly be a next hop router is selected so as to contribute to a load balancing, according to a whole or a prescribed part of information regarding a state of cut-through path set up in which the router device is involved, at a time of setting up a cut-through path in the multi-path, and a prescribed control for setting up the cut-through path with that one router as the next hop router is carried out. Also, one cut-through path that contributes to the load balancing when a route change is made is selected among cut-through paths for which the route change at the router device is possible, and a route of that one cut-through path is changed so as to contribute to the load balancing.

    Abstract: Disclosed is an apparatus and method for distributing traffic to one or more selected cache systems or servers. In general terms, a content addressable memory (e.g., a TCAM) is utilized to distribute traffic among a plurality of cache systems or servers. The content addressable memory is populated with a plurality of entries. Each entry within the content addressable memory generally indicates an action to be performed on a packet, such as to redirect the packet or to forward the packet to its original destination. When the action indicated by the content addressable memory is to redirect the packet, the content addressable memory also indicates where (e.g., to which cache system) to redirect the packet.
