Client-Server Assignment for Internet Distributed Systems

Overview Introduction Problem Definition Problem Model Solution Conclusion

Introduction Internet - Distributed System Example: ,IMS

Features: 1. Communication Load  Clients assigned to two different servers.  Clients assigned to same server. 2. Load Balancing  Use fewer servers. Servers are heavily loaded

Observations:

Problem Definition  Optimal client server assignment for a pre-specified trade-off between load balance and communication load. Emerging Applications: 1.Social networks Eg: Facebook 2.Distributed database system, Eg: MapReduce

Communication Model

Communication Load

Load Balance

Semidefinite Programming

Conclusion 1. Hard problems could be formulated as a optimization problem and solved. 2. optimization problems, are widely used in tremendous number of application areas, such as transportation, production planning, logistics etc.
