摘要： WAN optimization devices and content delivery networks together optimize network traffic on both private networks and public WANs such as the internet. A WAN optimization device intercepts and optimizes network traffic from clients within a private network. The WAN optimization device communicates this first optimized network traffic to the nearest edge computer in the content delivery network via a public WAN, such as the internet. This edge computer further optimizes the network traffic and communicates the doubly optimized network traffic via the content delivery network to a second edge computer nearest to the network traffic destination. The second edge computer converts the doubly optimized network traffic back to its original format and communicates the reconstructed network traffic from the second edge computer to the destination via a public WAN. Licensing and configuration portals configure WAN optimization devices for specific network protocols, types of network traffic, applications, and/or cloud services.

摘要： Digital certificates are distributed to WAN optimization modules in organization and content delivery networks to securely optimize network traffic. The content delivery network identifies edge WAN optimization modules for use with each combination of organizations and their cloud services and distributes digital certificates accordingly. Peering digital certificates for establishing inner connections between organization and edge WAN optimization modules are exchanged via one or more management portals. Shadow digital certificates for establishing outer connections between WAN optimization modules and clients are generated in the form of certificate signing requests. Configuration information identifies any additional cloud services associated with a given cloud service and generate corresponding additional certificate signing requests. Certificate signing requests are digitally signed by a certificate signing authority associated with the organization and then returned via the one or more management portals to the allocated edge WAN optimization modules. Digital certificates may be rotated for security purposes.

摘要： A single-ended optimized storage protocol enables storage clients or other devices to direct a remote data storage to copy data. In response to commands via the protocol, a remote data storage can copy portions of a data stream at the remote data storage to destination storage locations within the same or a different data stream. The protocol may be utilized for optimized transfer of data via a network to a remote data storage. An initial data stream is divided into segments. Redundant segments are removed from the data stream to form an optimized data stream, which is transferred to the remote data storage. Commands are issued to the remote data storage using the protocol to direct the remote data storage to reconstruct the initial data stream at the remote data storage using the optimized data stream and optionally segments from other data streams previously transferred to the remote data storage.

摘要： Network devices include hosted virtual machines and virtual machine applications. Hosted virtual machines and their applications implement additional functions and services in network devices. Network devices include data taps for directing network traffic to hosted virtual machines and allowing hosted virtual machines to inject network traffic. Network devices include unidirectional data flow specifications, referred to as hyperswitches. Each hyperswitch is associated with a hosted virtual machine and receives network traffic received by the network device from a single direction. Each hyperswitch processes network traffic according to rules and rule criteria. A hosted virtual machine can be associated with multiple hyperswitches, thereby independently specifying the data flow of network traffic to and from the hosted virtual machine from multiple networks. The network device architecture also enables the communication of additional information between the network device and one or more virtual machine applications using an extended non-standard network protocol.

摘要： Virtual storage arrays consolidate data storage at a data center for physical and virtual computer systems at one or more branch network locations. Standalone and virtualized computer systems at a branch network location load, execute, and store their operating systems, applications, and data using virtual storage arrays and do not require any built-in or external non-volatile data storage devices such as hard disk drives or solid-state drives at the branch network location. The virtual disks of the virtual storage array are mapped to physical data storage at the data center and accessed via a WAN using storage block-based protocols. A storage block cache at the branch network location includes storage blocks prefetched based on knowledge about the computer systems at the branch network location and the behavior of their operating systems and applications.

摘要： Virtual storage arrays consolidate branch data storage at data centers connected via wide area networks. Virtual storage arrays appear to storage clients as local data storage; however, virtual storage arrays actually store data at the data center. Virtual storage arrays overcome bandwidth and latency limitations of the wide area network by predicting and prefetching storage blocks, which are then cached at the branch location. Virtual storage arrays leverage an understanding of the semantics and structure of high-level data structures associated with storage blocks to predict which storage blocks are likely to be requested by a storage client. Virtual storage arrays may use proximity-based, heuristic-based, and access time-based prefetching to predict high-level data structure entities that are likely to be accessed by the storage client. Virtual storage arrays then identify and prefetch storage blocks corresponding with the predicted high-level data structure entities.

摘要： Virtual storage arrays consolidate branch data storage at data centers connected via wide area networks. Virtual storage arrays appear to storage clients as local data storage; however, virtual storage arrays actually store data at the data center. The virtual storage arrays overcomes bandwidth and latency limitations of the wide area network by predicting and prefetching storage blocks, which are then cached at the branch location. Virtual storage arrays leverage an understanding of the semantics and structure of high-level data structures associated with storage blocks to predict which storage blocks are likely to be requested by a storage client in the near future. Virtual storage arrays determine the association between requested storage blocks and corresponding high-level data structure entities to predict additional high-level data structure entities that are likely to be accessed. From this, the virtual storage array identifies the additional storage blocks for prefetching.

摘要： Network proxies reduce server latency in response to series of requests from client applications. Network proxies intercept messages clients and a server. Intercepted client requests are compared with rules. When client requests match a rule, additional request messages are forwarded to the server on behalf of a client application. In response to the additional request messages, the server provides corresponding response messages. A network proxy intercepts and caches the response messages. Subsequent client requests are intercepted by the network application proxy and compared with the cached messages. If a cached response message corresponds with a client request message, the response message is returned to the client application immediately instead of re-requesting the same information from the server. A server-side network proxy can compare client requests with the rules and send additional request messages. The corresponding response messages can be forwarded to a client-side network proxy for caching.
摘要翻译：响应于来自客户端应用程序的一系列请求，网络代理减少了服务器延迟。网络代理拦截消息客户端和服务器。拦截的客户端请求与规则进行比较。当客户端请求匹配规则时，代表客户端应用程序将其他请求消息转发到服务器。响应于附加请求消息，服务器提供相应的响应消息。网络代理拦截并缓存响应消息。随后的客户端请求被网络应用程序代理拦截，并与缓存的消息进行比较。如果缓存的响应消息对应于客户端请求消息，则响应消息立即返回到客户端应用程序，而不是从服务器重新请求相同的信息。服务器端网络代理可以将客户端请求与规则进行比较，并发送其他请求消息。相应的响应消息可以转发到客户端网络代理进行缓存。
