Description

METHOD AND SYSTEM FOR NETWORK TRAFFIC MANAGEMENT FIELD OF THE INVENTION [0001] Embodiments of the present disclosure generally relate to network performance management systems. More particularly, embodiments of the present disclosure relate to methods and systems for network traffic management. BACKGROUND [0002] The following description of the related art is intended to provide background information pertaining to the field of the disclosure. This section may include certain aspects of the art that may be related to various features of the present disclosure. However, it should be appreciated that this section is used only to enhance the understanding of the reader with respect to the present disclosure, and not as admissions of the prior art. [0003] Wireless communication technology has rapidly evolved over the past few decades, with each generation bringing significant improvements and advancements. The first generation of wireless communication technology was based on analog technology and offered only voice services. However, with the advent of the second-generation (2G) technology, digital communication and data services became possible, and text messaging was introduced. 3G technology marked the introduction of high-speed internet access, mobile video calling, and location-based services. The fourth-generation (4G) technology revolutionized wireless communication with faster data speeds, better network coverage, and improved security. Currently, the fifth-generation (5G) technology is being deployed, promising even faster data speeds, low latency, and the ability to connect multiple devices simultaneously. With each generation, wireless communication technology has become more advanced, sophisticated, and capable of delivering more services to its users. [0004] In a communication network, there are various nodes, components, functional units, and flows that perform various tasks assigned for the functioning of the network. However, due to the complex architecture of the network, it is very difficult to perform analysis and tracking of various network related functions such as getting insight into network flows, identifying any anomaly in traffic patterns, deviation in application performance, subscriber session debugging and to have collaborative troubleshooting across different network domains (say 5GC, IMS etc.). Also, to make informed decisions regarding network infrastructure management and planning, it is further required to monitor the performance of the application as well as the entire network. [0005] Further, over the period of time various solutions have been developed to track and analyse the network flows, however such methods and systems are not reliable and efficient due to various factors such as consume more time in analysis, have limited deployment capabilities, require more specific hardware components for deployment, cost increasing systems, and the like. [0006] Thus, in order to improve the radio access network capacity and performance, as well as to overcome the above limitation, there is an imperative need in the art for unified and collaborative approach to analyse and debug subscriber sessions as well as to track performance and statistics of applications and network, which the present disclosure aims to address.
