An efficient elastic enforcement layer (EEL) for realizing security policies is deployed in a cloud computing environment based on a split architecture framework. The split architecture network includes a controller coupled to switches. When the controller receives a packet originating from a source VM, it extracts an application identifier from the received packet that identifies an application running on the source VM. Based on the application identifier, the controller determines a chain of middlebox types. The controller further determines middlebox instances based on current availability of resources. The controller then adds a set of rules to the switches to cause the switches to forward the packet toward the destination VM via the middlebox instances.

A controller performs network-wide congestion control in a split architecture network. The controller receives flow statistics from switches for each entity that communicates via the network. The controller chooses a most congested link as a bottleneck link based on a packet loss rate that is derived from the flow statistics and estimated for each entity on each link of the network. The controller identifies a target path in the network that passes through the bottleneck link and carries the most traffic, and calculates a throttling probability for each sharing entity that shares the target path based on the capacity of the bottleneck link, capacity of the first link of the target path, bandwidth consumption and packet loss rate of each sharing entity. The controller then transmits the throttling probability of each sharing entity to the ingress switch of the target path to reduce the congestion on the bottleneck link.

Flow monitoring tasks are assigned to a set of switches in a split architecture network to optimize network-wide flow monitoring. The assignment maximizes the number of monitored flows and reduces overhead of the flow monitoring. A controller receives an estimated traffic volume for each path in the network. The controller calculates, for all of the switches and all of the paths, sampling fractions that maximize the number of the flows sampled by the switches. In response to a request for setting up a new flow to traverse one of the paths in the network, the controller assigns the new flow to one of the switches that are located on the one of the paths, based on the sampling fraction for the assigned switch and the one of the paths, the bandwidth constraint and the memory constraint.

A network element controls congestion in a link of a packet data network. A congested link is identified and a throttle rate is determined for one or more of the traffic groups traversing the congested link. The central controller determines the throttle rates using a weight of the group and the current traffic rate of the group through the link. The throttle rates are sent to switches to throttle traffic for each affected group.

A method implemented in a network element to determine an autonomous system (AS) path pre-pending (ASPP) vector for an AS of the network element that accounts for AS business relationship induced policies and global impact of ASPP decisions by using comparable paths between AS in a network for application of network management strategies, the comparable paths grouped by path types defined by local preference polices, the method including gathering AS level topological data for the network, categorizing AS link relationships in the topological data, computing the comparable paths for each AS pair, and applying any one of a load balancing process, back-up path provisioning process or traversal avoidance process to the comparable paths to determine an ASPP vector for the AS of the network element.

A method for localized congestion exposure within a local loop in a cellular network that is performed by a localized congestion exposure receiver node of the local loop. The method includes receiving downlink packets destined for a downstream user device. The downlink packets have headers that indicate a level of congestion experienced by the downlink packets. The headers also indicate a level of expected downstream congestion declared by an upstream node. The method also includes forwarding the downlink packets to the downstream user device through a wireless connection. The method further includes sending packets upstream that have feedback indicative of the level of congestion experienced by the downlink packets and any congestion experienced within the localized congestion exposure receiver node.

A system receives, at a server, an action request from a client associated with bookmarks, where the bookmarks identify user designated documents. The system accesses bookmark records stored at the server based on the action request and acting on the bookmark records in a manner specified by the action request.
