摘要： An example method is provided in one example embodiment and may include receiving a session request for a user equipment (UE) at a node, wherein the session request includes a timestamp for the UE and a retry count; determining if the session request is a stray session request; and maintaining session information for an existing session for the UE at the node if the session request is a stray session request. The method can include identifying the received session request as a stray request if the timestamp received in the request is less than a timestamp stored for an existing session for the UE. The method can also include identifying the received request as a stray request if the timestamp received is equal to the timestamp stored for the existing session and if the retry count received is less than or equal to a retry count stored for the session.

摘要： The present invention provides improved methods and devices for managing network congestion. Preferred implementations of the invention allow congestion to be pushed from congestion points in the core of a network to reaction points, which may be edge devices, host devices or components thereof. Preferably, rate limiters shape individual flows of the reaction points that are causing congestion. Parameters of these rate limiters are preferably tuned based on feedback from congestion points, e.g., in the form of backward congestion notification (“BCN”) messages. In some implementations, such BCN messages include congestion change information and at least one instantaneous measure of congestion. The instantaneous measure(s) of congestion may be relative to a threshold of a particular queue and/or relative to a threshold of a buffer that includes a plurality of queues.

摘要： A virtual network is overlaid upon physical networks. The virtual network is a layer-2 network that expands an organization's LAN using virtual MAC addresses. A VN device driver shim intercepts LAN packets and their virtual MAC and IP addresses and encapsulates them with physical packets. As new nodes are created, a VN switch table is expanded so that all nodes on the virtual network can reach the new node. A copy of the VN switch table is stored on each node by a virtual network management daemon on the node. A VN configuration controller in a central server updates the VN switch tables. Organizations can expand their virtual network as nodes are created at remote cloud computing providers without action by the staff at the cloud computing provider. Hybrid cloud virtual networks include on-premises physical and virtual-machine nodes, and off-premises guest nodes and instances.

摘要： The present invention relates to the security of general purpose computing devices, such as laptop or desktop PCs, and more specifically to the detection of malicious software (malware) on a general purpose computing device. A challenge in detecting malicious software is that files are typically scanned for the presence of malicious intent only once (and subsequent rescanning is typically performed in a simplistic manner). Existing methods in the art do not address how to most effectively rescan collections of files in a way that tries to optimize performance and efficacy. Accordingly we present novel methods, components, and systems for intelligently rescanning file collections and thereby enabling retroactive detection of malicious software and also retroactive identification of clean software. These methods may also be useful if additional information is now available regarding a file that might be useful to an end-user or an administrator, even though the file's core disposition might not have changed. More specifically, we describe methods, components, and systems that perform data analytics to intelligently rescan file collections for the purpose of retroactively identifying malware and retroactively identifying clean files. The disclosed invention provides a significant improvement with regard to efficacy and performance compared to previous approaches.

摘要： Techniques for system (syslog) messages are provided. As syslog messages are generated a dual sequence number is maintained for each syslog message. The first sequence number is consistent for each syslog message and represents a total number of syslog messages received. The second sequence number is maintained as a total message count for a specific session for which a syslog message is assigned.

摘要： In one embodiment, separate rate meters are maintained for each flow enqueued an increased at a target rate while a packet from the flow occupies the head of a shared transmit queue. The meter value is decreased by the packet length when a packet in enqueued or dropped. The next packet that occupies the head of the shared transmit queue is dropped if the meter value corresponding to the flow is greater than a threshold.
