Different Traffic Management Techniques �Service/user differentiation for congestion management �Strategies for mobile data traffic offloading �IP flow mobility for future wireless networks �Virtualization techniques for efficient network sharing

New Approaches in MTM • Deep packet inspection: Is an advanced method of packet filtering that functions at the Application Layer of the OSI reference model. • Innovation of protocols : When increase in real time network demand we need new innovation called lightweight UDP protocols.

• Virtualization: Operators will seek practical implementations of on-demand allocation of real-time service chains and dynamic resource allocation. • Video and encryption: Current network management with upgrades to support new technology In some parts of the world, 60% of traffic on mobile network is encrypted and it will reach 80%. • Inflexible data services: Inflexible billing and management.

Traffic Shaping This technique is used to optimize or guarantee the network performance. v Application based traffic shaping v. Route based traffic shaping

Bandwidth Management Issues �In the present days some end users who consume inordinate bandwidth and unexpected rise in demand from these users forced service providers to introduce network congestion and traffic management practices. �Bandwidth Usage: Cable, DSL and Fiber

Realistic service definitions and acceptable-use policies �The bandwidth congestion would not be so bad if the service providers were transparent and truthful in their service offerings. �The actual speed expectations were never specified Technical problems in the residential broadband market �Users who don't conform to expectations. �Peer-to-peer applications �Video streaming affects other applications �Undesired applications tend to be obfuscated and encrypted

NEUTRAL MANAGEMENT WITH LTE TECHNOLOGY Application-Agnostic prioritization in moderate congestion �The “throttle” capacity. Prioritization of like applications with like prioritization in severe congestion �Quality of Service(Qo. S) Increase in congestion, latency sensitive and bandwidth

Steps to implement in the proposed approach • Initiate a set of Qo. S profiles • The wireless network as an operator an application that should be placed in one of the profiles and receive Qo. S. • The active user device identifies itself to the edge providers default connection and operates application via network. • The edge provider authenticates the user device to use the application. • The wireless carrier sets up Qo. S between the user device and the Internet.

Challenges: • Today mobile broadband is being consumed at ever greater rates. • Because of this higher priority we need better solutions that optimize the mobile bandwidth. • Service providers responsible for congestion of services like streaming video, audio. . etc

Conclusion: • The LTE technology is capable of managing congestion through prioritization protocols. • When with severe congestion , prioritize latency-sensitive while avoiding discrimination among applications, content or services.
