Evaluating the Impact of Communication Architecture on the Performability of Cluster-Based Services

Kiran Nagaraja, Neeraj Krishnan, Ricardo Bianchini, Richard P. Martin, Thu Nguyen
2002
We consider the impact of different communication architectures on the performability (performance + availability) of cluster-based servers.  ...  In particular, we use a combination of fault-injection experiments and analytic modeling to evaluate the performability of two popular communication protocols, TCP and VIA, as the intra-cluster communication  ...  Our work here focuses more closely on cluster-based servers, and in particular the impact of faults affecting the communication system on service performability.  ...
