Some Practical Issues in the Design and Implementation of Group Communication Services

摘要

The main objective of the proposed research was to investigate four important practical issues in the understanding, design, and implementation of group communication services. These issues were (1) Performance: maintain good overall performance of group communication services under several different operating conditions, (2) Semantics: design a small set of powerful group communication semantics to ensure ease of implementation and good performance of the applications built using these services, (3) Flow control: design and evaluate efficient general purpose flow-control techniques that handle temporary buffers in group communication services and Real-time responsiveness: investigate the feasibility of designing and implementing real-time responsive group communication services implemented in distributed systems that are not completely synchronous.
