AI Technical Summary

Problems solved by technology

On the one hand, if the link is only partially used, then network resources may be wasted without proper return on investment
On the other hand, if the SLA is violated, then fines need to be paid, which can result in financial loss for the service provider

Embodiment Construction

[0037] The present invention relates to a method and a system for routing a data flow in a communication network and to a method and a system for selecting network resource requirements for the transmission of a data flow within a data communication network.

[0038]Aspects of some embodiments of the invention relate to systems and / or methods for classifying data flows (eg, packets) through a data communications network based on multi-parameter monitoring of current and / or previous network data flow patterns. Optionally, classification of new data streams is performed by a statistical classifier. Optionally, the statistical classifier consists of data collected from multi-parameter monitoring of current and / or previous data flow patterns of the same client used to request the new data flow. Alternatively or additionally, the statistical classifier is formed from data gathered from multi-parameter monitoring of other clients' current and / or previous data flow patterns.

Abstract

A method of classifying data flows through a data communications network for routing is provided, the method comprising: monitoring data flows in a data communications network; generating a statistical classifier based on the monitored flows; receiving a pair of data A request for routing of a flow of data packets in a communication network; classifying said flow based on said generated statistical classifier to predict network resource requirements for transmission of said flow through said network; selecting for said routing of said classified flow; and generating a signal indicative of said selected route, such that said flow is routed in said data communications network via said selected route.

Description

technical field [0001] The present application relates to methods and systems for routing data flows in a communication network and to methods and systems for selecting network resource requirements for transmission of data flows within a data communication network. Background technique [0002] Communication networks, such as cloud and / or data center networks, need to provide for a large number and / or large-size flows in the network while complying with a Service Level Agreement (SLA) associated with each of the flows. SLAs may define penalties for failure to provide a level of service, for example, failure to deliver data packets. Instead, the network is oversubscribed in order to use network resources economically and efficiently, eg, in order to benefit from the statistical multiplexing properties of model packet-based communication networks. [0003] Oversubscription is the act of providing the same resource several times. For example, two streams each requiring 100 M...
