If two communicating entities are in different hosts connected by a network,there is a risk that PDUs will not arrive in the order in which they were sent,because they may traverse(71)paths through the network. If each PDUs is given a unique number,and numbers are assigned(72),then it is a logically simple task for the receiving entity to reorder(73)PDUs on the basis of sequence number. A problem with this scheme is that,with a(74)sequence number field,sequence number will repeat.
