Abstract
THE PROBLEM OF COMPUTING WEIGHTS ON THE LINKS AND ROUTING DATA IN SHORTEST PATHS KNOWN AS OPEN SHORTEST PATH FIRST WEIGHTS SETTING PROBLEM (OSPFWSP) IS NONDETERMINISTIC POLYNOMIAL TIME CLASS )NP) COMPLETE)OSPFWSP IS DEFINED AS GIVEN ASET OF TRAFFIC DEMANDS BETWEEN ORIGIN- DESTINATION PAIRS, THE OPEN SHORTEST PATH FIRST WEIGHT SETTING PROBLEM CONSISTS IN DETERMINING WEIGHTS TO BE ASSIGNED TO THE LINKS SO AS TO MAKE EFFICIENT USE OF NETWORK RESOURCES. IN THE THESIS, A PROBLEM OF OPEN SHORTEST PHATH FIRST (OSOF) TRAFFIC ROUTING IN HYBRID NETWORK IS STSTED.THREE DIFFERENT METHODS ARE PROPOSED FOR SOLVING AND IMPLEMENTED IN REAL ENVIRONMENT. ALSO THREE PROPOSED ALGORITHMS ARE INTRODUCED FOR SOLVING OSPFWS PROBLEM THE PROPOSED ALGORITHMS USED DIFFERENT TECHIQUES FOR OPTIMIZING WEIGHTS .
