摘要： The invention provides for employing a complex data structure to optimize the retrieval of data over a network. The complex data structure includes two separate sub-data structures (Trie and List) that separately reference the same data objects in a data store. The Trie sub-data structure is used to fulfill a single data object request. The List sub-data structure is employed with function requests related to several data objects. Each data object is associated with a parent object that includes a list of every reference to the data object in both the Trie and List sub-data structures. A collector object is a type of data object that is associated with a member object and which includes a list of other related data/collector objects. When data associated with the collector object is requested, other data associated with the other data/collector objects on the member object list are automatically retrieved.

摘要： A method, system, machine-readable storage medium, and apparatus are directed towards upgrading a cluster by bifurcating the cluster into two virtual clusters, an “old” virtual cluster (old active cluster) and a “new” virtual cluster (new standby cluster), and iteratively upgrading members of the old cluster while moving them into the new cluster. While members are added to the new cluster, existing connections and new connections are seamlessly processed by the old cluster. Optionally, state mirroring occurs between the old cluster and the new cluster once the number of members of the old and new clusters are approximately equal. Once a threshold number of members have been transferred to the new cluster, control and processing may be taken over by the new cluster. Transfer of control from the old cluster to the new cluster may be performed by failing over connectivity from the old cluster to the new cluster.
摘要翻译：方法，系统，机器可读存储介质和装置旨在通过将集群分为两个虚拟集群，“旧”虚拟集群（旧主动集群）和“新”虚拟集群（新的备用集群）），并在将旧群集的成员移动到新群集中时迭代升级。当成员添加到新集群时，旧集群将无缝地处理现有连接和新连接。可选地，一旦旧集群和新集群的成员数量大致相等，就会在旧集群和新集群之间发生状态镜像。一旦将阈值数量的成员转移到新群集，则可以由新群集接管控制和处理。控制从旧集群传输到新集群可能会通过从旧集群到新集群的连接失败来执行。

摘要： Disclosed are methods and systems for providing persistence across multiple requests in a WAN load-balanced environment. More than one load balancing system may be used to provide persistence while load balancing. One method and system disclosed provides persistence by using modulus arithmetic to load balance requests. Another method and system disclosed provides persistence using topology information contained in the request. Another method and system disclosed provides persistence by storing connection information to refer a timely continuation request of a prior request to the same server the prior request was referred to. When more than one load balancing system is used with this method, the load balancing systems periodically exchange the stored connection information so that each load balancing system may provide persistence to repeat requests.

摘要： A system, apparatus, and method are directed to managing network communications between a client and a server by enabling the client to make decisions involving the selection of alternate network paths. The client and/or the server may be multi-homed to a network. In one embodiment, a link load balancer provides the client with a message and/or path data that enables the client to improve its connections with the server by redirecting network packets using an alternate network path. The message may be based on a static policy at the server, changes in availability of the network connections between the client and server, changes in a quality of the network connections, paths, or the like. Redirecting the network packet by the client may include closing one network connection and establishing another network connection, and/or employing an available alternate network path to re-route network packets towards the server.

摘要： A method and system for accessing network services. A client sends a request for a service. The request includes an address of the client. One or more resolvers receive the request for a service. The one or more resolvers determine at least one service location to return to the client based at least partially on the service requested and the address of the client. The at least one service location is then returned to the client. The service locations returned to the client may also be based on a policy, user preferences, client preferences, or client characteristics.

摘要： A system and method for balancing the load on virtual servers managed by server array controllers at separate data centers that are geographically distributed on a wide area network such as the Internet is described. The virtual servers provide access to resources associated with a domain name request by a client program. When a Primary Domain Name System (DNS) determined the requested domain name is delegated to a EDNS, the EDNS employs metric information and statistics to resolve an IP address for a virtual server that is selected by the EDNS to optimally balance the load and provide access to resources associated with the domain name. The EDNS may load balance name servers. Additionally, the name server load balancing system may bridge disparate content delivery networks. Internet addresses are divided into geographical information that is used to delegate traffic. Also, metric information is collected and analyzed to help distribute the traffic.
