Thus the paper proposes a new asynchronous transfer mode (ATM) switch architecture also known as barrel switch. It is made from n/2*n identical element switches which are kept around a cylindrical pattern and connected with each other.
The switch has following smart features
The switch architecture suites for high speed (<2.4 Gbps) cell switching.
It is non blocking and multistage self routing in nature.
The connections copied can be realized by the switch.
For switch implementation, building block method is applicable thus full scalability is achieved.
The cell loss rate and delay characteristic has been discussed by use of computer simulation result. Under random traffic, simulator result proves that 64*64 barrel switch has adequate cell loss rate and mean delay characteristics to an actual ATM switching system.
