1.2 How might the clocks in two computers that are linked by a local network be synchronized without reference to an external time source?
The procedure is subject to inaccuracy because of contention for the use of the local network from other computers and delays in the processing the messages in the operating systems of A and B.
For a local network, the accuracy is probably within 1 ms.
Migration of resources (information objects) is performed: to reduce communication delays (place objects in a server that is on the same local network as their most frequent users); to balance the load of processing and or storage utilisation between different servers.
An Ethernet switch must maintain routing tables giving the Ethernet addresses and network id for all hosts on the local network (connected set of Ethernets accessible from the switch).
