摘要： A data access request from an application for access to a data resource is received from a first application. The data access request is analyzed to identify application-specific behavior indicating a type of data access for the data resource. The WAN acceleration functionality of a first device is configured for network traffic optimization based on the type of data access for the data resource. The analysis of the data access request may be based on attributes of the data access request, the data resource, and/or an access control restriction. The network traffic optimization may be adapted to optimize network traffic to a first portion of the data resource that is different than a second portion of the data resource associated with the data access request or to a second data resource separate from the data resource associated with the data access request.
摘要翻译：从第一应用接收来自应用程序访问数据资源的数据访问请求。分析数据访问请求以识别指示数据资源的数据访问类型的特定于应用程序的行为。基于数据资源的数据访问类型，将第一设备的WAN加速功能配置为网络流量优化。数据访问请求的分析可以基于数据访问请求，数据资源和/或访问控制限制的属性。网络流量优化可以适于优化与数据资源的第一部分不同于与数据访问请求相关联的数据资源的第二部分的网络流量或者与从数据资源相关联的数据资源分离的第二数据资源数据访问请求。

摘要： In a system where transactions are accelerated with asynchronous writes that require acknowledgements, with pre-acknowledging writes at a source of the writes, a destination-side transaction accelerator includes a queue for queue writes to a destination, at least some of the writes being pre-acknowledged by a source-side transaction accelerator prior to the write completing at the destination, a memory for storing a status of a destination-side queue and possibly other determinants, and logic for signaling to the source-side transaction accelerator with instructions to alter pre-acknowledgement rules to hold off on and pursue pre-acknowledgements based on the destination-side queue status. The rules can take into account adjusting the flow of pre-acknowledged requests or pre-acknowledgements at the sender-side transaction accelerator based at least on the computed logical length.

摘要： Systems and methods, including computer program products, providing high-availability in server systems. In one implementation, a server system is cluster of two or more autonomous server nodes, each running one or more virtual servers. When a node fails, its virtual servers are migrated to one or more other nodes. Connectivity between nodes and clients is based on virtual IP addresses, where each virtual server has one or more virtual IP addresses. Virtual servers can be assigned failover priorities, and, in failover, higher priority virtual servers can be migrated before lower priority ones. Load balancing can be provided by distributing virtual servers from a failed node to multiple different nodes. When a port within a node fails, the node can reassign virtual IP addresses from the failed port to other ports on the node until no good ports remain and only then migrate virtual servers to another node or nodes.

摘要： A system of network proxies distributes data to multiple servers. Each network proxy is associated with a server. A network proxy intercepts a client request for data. If the network proxy determines that the request can be served using a copy of data stored on the local server, rather than the data stored on a remote server, it diverts the request to the local server. If the network proxy determines that the request cannot be served using a data from the local server, the network proxy diverts the request to a remote server storing the primary copy of the data. A server map specifies the locations of the primary copies of data. When a primary copy of data is updated on one of the servers, the associated network proxy propagates the updated data to the other servers. The servers can provide data from files, e-mail services, databases, or multimedia services.

摘要翻译：网络代理系统将数据分发到多个服务器。每个网络代理与服务器相关联。网络代理拦截客户端数据请求。如果网络代理确定可以使用存储在本地服务器上的数据副本来提供请求，而不是存储在远程服务器上的数据，则会将请求转发到本地服务器。如果网络代理确定不能使用来自本地服务器的数据来服务请求，则网络代理将请求转发到存储数据的主副本的远程服务器。服务器映射指定数据的主副本的位置。当数据的主副本在其中一个服务器上更新时，相关的网络代理会将更新的数据传播到其他服务器。服务器可以从文件，电子邮件服务，数据库或多媒体服务中提供数据。
