摘要： A technique for end-to-end admission control of real-time packet flows is disclosed. In one particular exemplary embodiment, the technique may be realized as a method for end-to-end admission control of real-time packet flows in a network having a plurality of network elements. The method may comprise transmitting at least one probe packet from a first network element to a second network element via a network path, determining, at least one intermediate network element on the network path, at least one flow rate associated with a plurality of packets, marking at least one predetermined bit in the at least one probe packet if the at least one flow rate is greater than a predetermined rate, and controlling an admission of additional packets into the network based at least in part on the marking of the at least one predetermined bit in the at least one probe packet.

摘要： Wireless networks and devices are ubiquitous today. For service providers to offer customers QoS and Service Level Agreements (SLAs) means in part providing resilient connectivity of wireless devices with good signal strength, good Signal to Noise and Interference Ratio (SNIR), and adequate useable bandwidth. Doing so requires that devices transmitting and receiving packets use over-the-air bandwidth efficiently and manage over-the-air congestion. According to embodiments of the invention QoS measurements and controls are incorporated only in the network (i.e. APs or controllers) and therefore QoS and SLAs can be achieved with all deployed client stations versus standards based approaches that require additional capabilities in network nodes, client stations and in most cases modifications to the applications. SLAs can be provided exploiting embodiments of the invention for traffic prioritization, capacity improvements through load distribution, and adjacent channel interference mitigation discretely or in combination with standards based mechanisms.

摘要： A flow admission control module for IP traffic types monitors network topology and usage. A new flow is not admitted if it is determined that the flow would push the utilization of available bandwidth reserved for the traffic type on a link in the associated path beyond a predetermined threshold. The admission control module may, as a result of dynamic changes to network topology capacity, re-compute the link utilization for effected active flows The admission control module may also account for protection regimes in flow admission calculations.

摘要： A flow based routing method and apparatus selects a path from a plurality of different paths for assignment to a flow. The path is selected based on a traffic performance measurements which identify relative congestion and performance of the different paths, so that traffic flows can be diverted away from network congestion points, thereby allowing network resources to be load balanced at a flow granularity. The present invention may be configured on physical or virtual links on an NE to enhance the forwarding of packets using the primary link and one or more alternate links to any given destination.

摘要： An embodiment of the present invention includes a technique to provide anti-replay protection with QoS queues. A single global anti-replay window is maintained to have global lowest and highest sequence numbers for an Internet protocol security (IPSec) security association (SA). The single global anti-replay window is associated with individual differentiated services code point (DSCP) or DSCP group, the individual DSCP or DSCP group corresponding to individual per-DSCP anti-replay windows. A received packet having a sequence number is pre-processed before packet processing using the single global anti-replay window. The received packet is post-processed after packet processing using the individual per-DSCP anti-replay windows.
