Posted on May 15 2009. Question # 1 Consider the network given above with each link associated with its cost. Apply Dijkstra’s algorithm in order to find the least cost path from node A to node F. Clearly show the operation details by indicating each step and filling up the table below with the appropriate tentative (temporary) and permanent labels. Algorithm Step # Tentative (Temporary) Labels Permanent Labels 1 2 ... Solution: Algorithm Step # Tentative Labels Permanent Labels 1. Working node A: B(2,A) C(1,A) D(4,A) C(1,A) 2. Working node C: D(3,C) F(5,C) B(2,A) B(2,A) 3. Working node B: E(3,B) D(3,C) F(5,C) D(3,C) 4. Working node D: E(3,B) F(5,C) (Nothing new) E(3,B) 5. Working node E: F(4,E) F(4,E) The least cost path from A to F=ABEF with cost 4. Question # 2 You are managing the IP network of a school.
