What are the benefits of a multispeed network?
What will be an ideal response?
The purpose of a multispeed network (one with a backbone) is to provide the fastest network speed, while keeping costs down. Rather than have the entire network operate at a higher speed with very expensive equipment, a multispeed network uses a high-speed backbone to connect other network segments.

As a second example, consider the communication paradigm referred to as queued RPC, as introduced in Rover [Joseph et al. 1997]. Rover is a toolkit to support distributed systems programming in mobile environments where participants in communication may become disconnected for periods of time. The system offers the RPC paradigm and hence calls are directed towards a given server (clearly space-coupled). The calls, though, are routed through an intermediary, a queue at the sending side, and are maintained in the queue until the receiver is available. To what extent is this time-uncoupled? Hint: consider the almost philosophical question of whether a recipient that is temporarily unavailable exists at that point in time.
