3. JRMS -- An Introduction

The Java Reliable Multicast Service (JRMS)

is a set of libraries and services for building multicast-aware applications.
enables building applications that distribute data from senders to receivers over channels with distributed control over content mix.
includes a dynamic filtering mechanism that uses Java software that is pushed into the network for interpreting the data on the receiver side.
supports multiple reliable multicast transport protocols via a common programming interface, which provides isolation to applications.
supported transport protocols are selectable by applications based on reliability and type of service needs.

The JRMS reliable multicast transport protocol (TRAM) is designed for high scalability.
JRMS includes related services for multicast address allocation, channel advertisement and subscription, authentication and encryption, and receiver group management.
JRMS is designed to be a flexible toolkit to the application developer for authoring new types of network-centric multimedia applications.

--: Provide a platform for building multicast-aware applications organized as a set of libraries and services implemented on end stations
--: Provide applications with access to multiple reliable multicast protocols through a common API which isolates applications from protocol changes, yet allows selecting appropriate protocols based on application needs.
--: Design a highly scalable bulk data transfer protocol for large numbers of receivers which includes support for congestion detection, avoidance, and control
--: Provide services for multicast address allocation, security (authentication and encryption), and administrative policy control
--: Flexibility
--: Add new reliable multicast protocols with minimal impact to applications
--: Provide a mechanism for applying administrative policy to data at the receivers (dynamic filters)
