Resilience

We wish a shared editor to be resilient to network conditions including packet loss, link failure, and failure of any participating end system. In combination with the scalability requirement, the necessity to tolerate link or end-system failures implies that a distributed, replicated data model is appropriate. Resilience to packet loss can be achieved through redundancy, through retransmission, or through network reservation. Network reservation as is not widely available and we will aim to show that it is unnecessary for this sort of application.
