Case 1: 1 TCP flow and 1 UDP flow with same rates (Traffic without QoS)

Same flows with DiffServ over MPLS test-bed:

Case 2: 2 UDP flows with same rate but different packet sizes (Traffic without QoS)

With DiffServ over MPLS:

Case 3: Single UDP flow with link failure

Path recovery with conventional OSPF

Same flow with DIffServ over MPLS (MPLS FRR):
