-- An alternative version of the same strategy is to use machine dependent format for messages local to the machine (perhaps also for messages between the same type of machine), and then to use a canonical format on the network. This requires very little more overhead than the strategy of always using a canonical format, yet avoids the cost of translations in the most important cases. This strategy is actually implemented by the Accent (and now Mach) IPC systems. It is possible because messages contain type information describing the fields in them. Non-local messages are implemented by a server which translates the messages and sends them over the net. At the same time, the anonymous nature of the port abstraction allows applications to remain ignorant of whether the messages they send are local or not. Rob --
