N2  - This Research study is directed towards t he problems of  Routing in packet switched communication networks. Its a function  performed in the third layer (network layer) of the OSI 7 layer  architecture.  The objective of good routing is to achieve overall minimum  time delay for packet transmission. Delay occurs because of  queueing and processing delay in the nodes , propagation delay in  the channels. From the basics of queueing theory it is seen that  the expression for time d e lay (it is called the objective  function) is a non- linear function in terms of the link flows,  capacities of the channels etc.  The function  methods; Gradient  software package  methods have been  for time delay has been minimized by using two  Projection Method and by using NPSOL , a  for minimizing non- linear functions. Th ese  implemented for few representative networks .  A comparison between the optimal routing and the best fixed  routing has been done.  It is concluded that in optimal routing , the time delay is  mini mi zed by distributing the packets over the available links in  the network in a correct manner.
