Advanced Load Balancing Algo

Server Core uses default Round Robin algorithm provided by Synapse Problems : Nodes are heterogeneous in terms of performance

& locations

High risk of allocating high performing & available nodes to low performing & available services and vice versa

Solution : Advanced round robin algorithm based on

performance & availability of nodes & services

Measuring Node’s availability & Performance

Availability : Node total Contribution

Performance : Node Benchmark

Define node weight as

Measuring WS’s availability and performance

Availability : hit rate (request count)

Performance : web service size

where c is the performance constant in both cases

2/1/2009MOINC Server Manager 5

Clustering and Service Grouping Predefined no of domains Decide boundaries for domains based on statistics of

weights

Both nodes and web services grouped in the same manner

As a result, clusters and service groups are mapped

Agent Benchmarking

Agent is benchmarked according to Linpack Algorithm

2/1/2009MOINC Server Manager 8

Verifying Benchmarking algo

Why we need to verify benchmark Algorithm ?

Benchmark directly used for credit calculating

All the source code is freely available

Attacks can be happen from malicious participants

How verification happens ?

Agent send the MD 5 hash value with idle request and compared with the initial hash value
