Summary:Abstract: "The ISIS toolkit is a distributed programming environment based on support for virtually synchronous process groups and group communication. We present a new suite of protocols in support of this model. Our approach revolves around a multicast primitive, called CBCAST, which implements a fault-tolerant, causally ordered message delivery. This primitive can be used directly, or extended into a totally ordered multicast primitive, called ABCAST. It normally delivers messages immediately upon reception, and imposes a space overhead proportional to the size of the groups to which the sender belongs, usually a small number
We conclude that process groups and group communication can achieve performance and scaling comparable to that of a raw message transport layer - a finding contradicting the widespread concern that this style of distributed computing may be unacceptably costly.
