摘要： Serial clustering uses two or more network devices connected in series via a local and/or wide-area network to provide additional capacity when network traffic exceeds the processing capabilities of a single network device. When a first network device reaches its capacity limit, any excess network traffic beyond that limit is passed through the first network device unchanged. A network device connected in series with the first network device intercepts and will process the excess network traffic provided that it has sufficient processing capacity. Additional network devices can process remaining network traffic in a similar manner until all of the excess network traffic has been processed or until there are no more additional network devices. Network devices may use rules to determine how to handle network traffic. Rules may be based on the attributes of received network packets, attributes of the network device, or attributes of the network.

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： 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： 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. 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 traffic is monitored and an optimal framing heuristic is automatically determined and applied. Framing heuristics specify different rules for framing network traffic. While a framing heuristic is applied to the network traffic, alternative framing heuristics are speculatively evaluated for the network traffic. The results of these evaluations are used to rank the framing heuristics. The framing heuristic with the best rank is selected for framing subsequent network traffic. Each client/server traffic flow may have a separate framing heuristic. The framing heuristics may be deterministic based on byte count and/or time or based on traffic characteristics that indicate a plausible point for framing to occur. The choice of available framing heuristics may be determined partly by manual configuration, which specifies which framing heuristics are available, and partly by automatic processes, which determine the best framing heuristic to apply to the current network traffic from the set of available framing heuristics.
