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： Systems and techniques are described for ensuring that policies are consistently applied to traffic across an overlay network. An application identifier associated with a forward traffic flow and a corresponding reverse traffic flow can be determined by a device that routes packets of both the forward traffic flow and the corresponding reverse traffic flow. Next, an overlay header can be added to each packet in the forward traffic flow and to each packet in the corresponding reverse traffic flow, wherein the overlay header comprises the application identifier, a policy identifier, and a policy action. Each device in the overlay network can then apply the policy action specified in the overlay header of each packet that it routes.

摘要： Systems and techniques are described for compressing strings by using a tree data structure. Specifically, for each string in a sequence of strings, the embodiments can traverse the tree data structure by matching characters of the string with characters associated with nodes of the tree data structure until either (1) all characters in the string have been processed, or (2) a current character in the string does not match a corresponding character in a current node of the tree data structure. Next, a first node identifier associated with the current node can be returned if all characters have been processed. Otherwise, a new node can be created in the tree data structure to store the remaining characters in the string, and a second node identifier associated with the new node in the tree data structure can be returned.

摘要： Systems and techniques are described for configuring path selection in a network. The network can comprise a first router, a second router, a third router, a fourth router, and an intermediary device. The second router can be configured to use Differentiated Services Code Point (DSCP) while routing packets so that packets with a first DSCP value are routed through the third router, and packets with a second DSCP value are routed through the fourth router. The intermediary device can be configured to: (1) transparently intercept a packet forwarded by the first router to the second router, (2) determine whether the packet is to be routed through the third router or the fourth router, (3) modify a DSCP field in the packet based on said determining, and (4) forward the packet to the second router.

摘要： Systems and techniques are described for path selection. A packet can be transparently intercepted at an intermediary device. Next, the intermediary device may modify one or more bits in the header of the packet. The intermediary device can then forward the packet to the next hop device. In some network configurations, the modifications to the one or more bits in the header of the packet may cause a downstream device to select a path that is different from the path that would have been selected by the downstream device if the one or more bits in the header of the packet had not been modified. A path selection policy can be used to determine whether or not one or more bits in the header of the packet are to be modified.

摘要： Systems and techniques are described for performing minimally invasive monitoring of path quality in a network. Specifically, path quality requests and measurements can be piggy-backed on the data traffic that is flowing through a secure connection between two network nodes. For example, path quality requests and measurements can be inserted into the TFC padding field of IP/ESP packets that are being communicated between two IPsec devices. The disclosed embodiments ensure that the number/frequency of measurements increases/decreases naturally in proportion to the amount of traffic flowing, and that the measurement data does not get differential treatment in the network as they are intrinsically bound to the data packets being monitored.

摘要： A method and system that takes advantage of processes that are efficient for determining the topology of small to medium size networks to determine individual network topologies for such networks, and then merges these individual topologies into a consolidated topology for the entire network. Each of the processes that determines the topology of the smaller networks provides the determined network topology, as well as a list of factors that may be relevant in the determination of how the given topology might be attached to any other given topology, such as the identification of a node that is not included in the given topology, or other indications of external connections. The merging process is configured to substantially restrict its analysis to these factors, thereby limiting the extent, and therefore the time consumed, by this stitching and merging process.

摘要： Embodiments provide systems, methods, and computer program products for dynamically hooking multiple levels of application code. A server receives identifying information that identifies a target function of a target application to hook. The server pauses a target process of the target application. The server locates the target function within the target application code based on the received identifying information. The server then hooks the located function outside of the target application, thereby creating hooked code during application runtime.

摘要： In a network that includes intermediary nodes, such as WAN accelerators, that transform messages between nodes, an end-to-end path of the messages is determined. The determined end-to-end path is used in subsequent analyses of message traces, to identify timing and other factors related to the performance of the network relative to the propagation of these messages, including the propagation of the transformed messages. A variety of techniques are presented for determining the path of the messages, depending upon the characteristics of the collected trace data. Upon determining the message path, the traces are synchronized in time and correlations between the connections along the path are determined, including causal relationships. In a preferred embodiment, a user identifies an application process between or among particular nodes of a network, and the system provides a variety of formats for viewing statistics related to the performance of the application on the network.
