Problems solved by technology

Unfortunately, QoS algorithms are becoming more and more intricate, making QoS configuration even more complicated
Typical network administrators with little or no knowledge of QoS algorithms are unlikely to effectively configure QoS parameters and cannot adjust QoS parameters as business conditions change

Embodiment Construction

[0011] Various traditional network architectures provide flow-based or classification-based QoS mechanisms. Flow-based mechanisms include Integration Services (IntServ or IS), which employs the Resource Reservation Protocol (RSVP) to make network resource reservations for each specific flow or data passing through the network.

[0012] Classification-based mechanisms include Differentiated Services (DiffServ or DS), sometimes called "provisioned QoS." Instead of reserving resources for specific flows, DiffServ divides traffic into ordered service classes

[0013] (COSe), and then treat these classes as aggregate flows on a hop-by-hop basis. The current IP implementation of DiffServ defines eight COSes. To achieve this goal, DiffServ provides a standard method of encoding the existing Type of Service (TOS) field in the header of an IP packet into DS bytes, the most significant bit being defined as DSCP. Additional information in the DS byte defines per-hop behavior.

Abstract

A system and method for dynamically adjusting QoS configuration and a network in which said system or said method is employed. In one embodiment, the system includes: (1) a QoS control engine configured to identify traffic types of packets conveyed through a network and maintain statistics indicating a traffic mix of the network and (2) a QoS configuration database coupled to the QoS control engine and configured to contain QoS configuration information corresponding to the traffic types and provide at least some of the QoS configuration information for carrying out QoS with respect to the network in response to a request from the QoS control engine.

Description

technical field [0001] The present application generally relates to network management, and more particularly, to systems and methods for dynamically adjusting quality of service (QoS) configurations based on real-time traffic. Background technique [0002] With the advent of next-generation networking, agencies are increasingly relying on their networks to deliver Internet Protocol (IP) communications and mission-critical information. With the trend toward IP telephony and converged applications becoming a reality, there is now a greater need to incorporate QoS into the network infrastructure. QoS includes a set of mechanisms that give priority to delay-sensitive applications and make the network more efficient and reliable for all applications. [0003] QoS is designed to sequence traffic and allocate network resources so that information reaches its destination smoothly and predictably. It enables traffic to be classified based on shared characteristics, allowing priori...
