摘要： A system and method is provided for providing an initial determination of the type of application recognition processing that is required for incoming traffic, and directing the packets accordingly. The invention is based on optimized resource allocation that uses multiple, application-dependent data paths. An exemplary set of application-dependent data paths includes, for example, Fixed Attribute Table (FAT), Deep Packet Inspection (DPI) and CPU Processing data paths. By using optimized and application-dependent network traffic processing paths, it is possible to achieve a less resource-hungry hardware design than previously contemplated in the prior art, where all traffic proceeded along a single path and was subjected to DPI processing.

摘要： A group of packets are extracted based on data captured from packets transmitted between communication apparatuses, where each packet has an identical transmission source address or an identical transmission destination address, and is transmitted in an identical connection. First and second beginning-packet candidates, which are transmitted within the identical connection, are identified based on a time difference of capturing individual packets included in the group of packets. A message length is calculated from lengths of packets including the first beginning packet candidate, captured before capturing the second beginning-packet candidate and after capturing the first beginning-packet candidate. A position, at which a message length of a message formed by the group of packets is stored, is estimated from the first beginning-packet candidate, based on the calculated message length, and the message formed by the group of packets is detected in accordance with the message length stored at the estimated position.

摘要： Techniques for tracking and adjusting packet flows through a network having a service delivery node and one or more demarc points. Packet flows recognized as they pass through one or more demarc point and flow analytics information corresponding to the packet flows are transferred from the demarc points to the flow identification control unit. The flow analytics information is analyzed within the flow identification control unit and traffic through one or more of the service access platform and the demarc points is adjusted, if necessary, as a function of the flow analytics information analyzed by the flow identification control unit.

摘要： Embodiments of the present invention provide methods and system to reduce needless data traffic in leaf-spine switch fabric. In embodiments, in a static solution, data rates of data flows having a common destination port may be measured and responsive to the data flows having a combined data rate that exceeding a rate limit of the common destination port, one or more of the data flows may be limited. Embodiments may also comprise a global scheduler to provide dynamic data rate controls of traffic flows from source ports to destination ports in which to reduce the handling of data traffic that would otherwise be discarded due to oversubscription.

摘要： A method is provided in one example embodiment and includes receiving at a network element a flow offload decision for a first service node that includes a portion of a service chain for processing a flow; recording the flow offload decision against the first service node at the network element; and propagating the flow offload decision backward on a service path to which the flow belongs if the first service node is hosted at the network element. Embodiments may also include propagating the flow offload decision backward on a service path to which the flow belongs if the flow offload decision is a propagated flow offload decision and the network element hosts a second service node that immediately precedes the service node on behalf of which the propagated flow offload decision was received and a flow offload decision has already been received by the network element from the second service node.
