A programmable multicast service in ATM

This paper presents a design and implementation of a ATM multicast service based on programmable and active network concepts. It aims to address the design and implementation issues of creating new network services, multicast in this case, through a set of Corba-based network interfaces, and with a Java-based user code injection mechanism for supporting customization of network 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 support of heterogeneous receivers. The performance of the prototype over an ATM test-bed is measured and evaluated.
