Adaptive Real-Time Traffic Engineering using Software Defined Networks, BSCS Projects

Introduction
In continues development environment the traditional network cannot meet
the requirements of today’s dynamic and real-time application. Programmable
Software Defined Networking (SDN) is a developing design that is dynamic,
sensible, and capable to improve the innovation of network application, making it
perfect for the high-transmission capacity to dynamic nature applications. SDN main
idea is to decouple the control layer and data forwarding layer. Traditional systems
join these two planes on the similar gateway. SDN has a logically centralized controller
that has globally responsible for all control decision and communicate the wide
forwarding plain to the network. We can control all the changes and deployment very easily by SDN. This new engineering model gives an approach to automatically design the switches at runtime and to deal with the system assets in a more effective manner.
It improves the system administrator to give data transfer capacity “on request”. SDN can improve the quality of service (QoS) framework by introducing network reconfiguration and provide high-level policies. SDN provides the dynamic QoS by which other application neither effected.
Traffic Engineering (TE) is the research-based important application of SDN. We can improve all resources utilization and quality of service (QoS) to meet all network requirements by Traffic Engineering. For traffic engineering analyzing of network traffic is important. If traffic is analyzed then we can do traffic engineering according to requirements. Traffic can be analyzed by port-based classification. In this thesis over main work is to analyze the traffic and identify the
data packets and then assign bandwidth according to requirement. Identification of traffic is done by Port Number, Statistical analysis and DPI (Deep Packet Inspection).We use DPI to analyze the network traffic.
