A programmable ATM multicast service with congestion control

This paper presents a design and implementation of a ATM multicast service based on programmable and active network concepts. It aims to address the d esign and implementation issues of creating new network services-multicast in this case-through a set of corba-based network interfaces, and with a ja va based user codes injection mechanism for supporting customization of net work services. We demonstrate the feasibility of our prototype through the implementation of a wavelet video multicast application with active filters implanted at intermediate nodes for supporting heterogeneous receivers and the implementation of a congestion control scheme. The performance of the prototype over an ATM test-bed is measured and evaluated.
