time-stamping

It is a method proposed by Lamport, used to sequencing events in a distributed machine without the use of clocks. This process is intended to order events consisting of the transmission of codes. Each machine 'i' in the network used to maintain a counter Ci. Each time a system transmits a code; it adds its counter by 1 and selected the time-stamp Ti to the code. When a message is get, the receiving system 'j' puts its counter Cj to 1 more than the largest of its current number and the incoming timestamp Ti. At every site, the ordering of codes is calculated by the following principle: For messages x from site y and i from site j, x goes beyond y if one of the following conditions true....(a) if Ti
