摘要： Methods, apparatuses and systems directed to improving the efficiency of bandwidth allocation schemes by adapting to slow-start mechanisms associated with network communications protocols, such as the TCP/IP protocol suite. In one implementation, the present invention scales down the initial target rate assigned to a data flow to a fraction of an initial estimate of the effective rate capacity of the communications path between two hosts. As packets are received, the target rate is gradually increased, eventually up to the detected rate capacity of the communications path. Implementations of the present invention improve the efficiency of bandwidth allocation by reducing the over-allocation of bandwidth to data flows during the slow-start phase, leaving more bandwidth available to other data flows.

摘要： Methods, apparatuses and systems directed to an aggregate bandwidth utilization control scheme including fair share bandwidth allocation and dynamic allocation of bandwidth in response to detected traffic utilization. In one implementation, the present invention includes a weighted, fair share aggregate bandwidth allocation mechanism that dynamically responds to observed bandwidth utilization to provide unutilized or excess bandwidth to flows and partitions that require it. In another implementation, the present invention features a weighted fair share allocation scheme for hierarchical partition configurations. In other implementations, the present invention provides a per-flow target rate assignment mechanism that prevents spiraling decline of data flow rates.

摘要： A method for controlling data rate at an application layer. The method, in a particular implementation, includes identifying an application-layer message corresponding to a network application, wherein the application-layer message is transmitted in a first direction from a first host to a remote host and is operable to cause the remote host to transmit one or more responsive messages to the first host. A queuing delay is computed for the application-layer message and transmission of the application-layer message across a link to the remote host is delayed according to the queuing delay wherein the computed queuing delay is based at least in part on utilization of the link in a direction opposite the first direction of network traffic corresponding to the network application.

摘要： A method for enforcing a network policy is described herein. In the method, a network socket event request from an application executing in a first context is intercepted by an agent prior to the request reaching a transport layer in the first context. A context refers to virtualization software, a physical computer, or a combination of virtualization software and physical computer. In response to the interception of the request, the agent requests a decision on whether to allow or deny the network socket event request to be communicated to a security server executing in a second context that is distinct from the first context. The request for a decision includes an identification of the application. The agent then receives from the security server either an allowance or a denial of the network socket event request, the allowance or denial being based at least in part on the identification of the application and a security policy. The agent blocks the network socket event from reaching the transport layer when the denial is received from the security server. In one embodiment, the method is implemented using a machine readable medium embodying software instructions executable by a computer.

摘要： Methods, apparatuses and systems directed to an adaptive partitioning mechanism responsive to observed latency conditions in a communications network. Embodiments of the present invention can be configured to adapt to changing network conditions and ensure that selected network applications meet desired QoS levels. In one implementation, the present invention provides a mechanism that adjusts the minimum bandwidth setting corresponding to a given partition in response to observed latency. According to one implementation, a latency threshold is configured relative to local queuing latency or a latency metric corresponding to the network itself. A process modulates the minimum bandwidth setting associated with one or more partitions in response to observed latency relative to the configured threshold.
