The TCP/IP protocol suite is the standard requirement for all applications that need to communicate over the Internet. As TCP/IP applications are unable to specify the QoS parameters needed for most Asynchronous Transfer Mode (ATM) services, we tend to use the GCRA Algorithm.
The purpose of Cell-Rate Guarantees for Traffic across ATM Network is to provide QoS. ATM is a connection-oriented switching technology, utilizing statistical multiplexing of fixed-length packets, known as cells.
The purpose of traffic control is to minimize congestion. In an ATM network when the Source Machine continuously sends cells to the Destination Machine through the Router Machine, there will be a possibility of occurring congestion. When congestion occurs the Routing Machine cannot accept more cells and hence these cells will be discarded. This causes regeneration and retransmission of the discarded ATM cells.
The objective of this project is to simulate an overflowing ATM network and establish a router with congestion control based on the GCRA algorithm.
This system can be implemented in a real network to control the traffic occurred in a network. Users can get to know the status of the router whether the router is busy controlling the inflow and outflow of data to transfer data to the destination.
In this System, using several algorithms viz. Leaky bucket algorithm and Virtual scheduling algorithm congestion can be avoided. Leaky Bucket Algorithm continuously receives and sends the data at a particular interval of time to avoid congestion or flooding of data. Virtual scheduling algorithm monitors the congestion occurrence, when congestion occurs it intimates or warns the user and simultaneously intimates when the router is free and data transferred successfully to destination.
