“…In (Lai et al, 2008), a method has been proposed, which attempts to establish all possible bypass tunnels based on the available bandwidth between two LSRs around the protected label switched router in MPLS. When a link or a LSR is broken, the LSR that detects the failure chooses a bypass tunnel to reroute traffic for each affected LSPs.…”

Problem statement: Traditional IP networks have many limitations such as routing tables, which can be complex and time consuming. These limitations affect the performance of the network in some applications of triple play services (i.e., voice, video and data) which are characterized as time sensitive applications. Thus, Multi Protocol Label Switching (MPLS) technology has been proposed to speed up the traffic flow in the network using labels. Approach: In this study, an experiment using the Network Simulator NS-2 was performed to evaluate the impact of MPLS technology on the Triple Play Services based on the average throughput of the network, total number of packets received at destination nodes and packet loss rates and this is compared to that provided by traditional IP networks. Results: The results showed that MPLS performs better since it utilizes all the available paths to the destinations. Conclusion: MPLS allows Internet Services Providers (ISPs) to provide better triple play services for end-users

“…Network with MPLS can offer good QoS to delay sensitive traffic such as VoIP, video conferences and meetings. Network failure such as link faults, crash of network elements or congestion are easily handled in MPLS networks [15][16][17][18][19].…”

This paper presents comparison study based on link utilization in the networks running over RIP (Routing information Protocol), OSPF (Open Shortest Path First) and MultiProtocol Label Switching (MPLS). Poor link utilization in case of RIP and OSPF is identified. A detailed simulation study is performed over MPLS network where we have shown MPLS network has utilized most of links resulting in congestion avoidance, low queuing delays.

“…Hence, the Quality of Service (QoS) of real-time applications using UDP is affected by TCP traffic and its flow control mechanism whenever TCP and UDP share the same network resources [2] . Many researches have been conducted for improve the protection mechanisms of MPLS networks using a UDP traffic [3,4] . However, study the behavior of TCP and UDP traffic over MPLS networks in case of failure is an essential issue for fast failure detection and recovery.…”

Problem statement:In only a few years, Multi-Protocol Label Switching (MPLS) has evolved from an exotic technology to a mainstream tool used by service providers to create revenuegenerating services. MPLS provides a high reliable Label Switched Path (LSP). MPLS failures may degrade the reliability of the MPLS networks. Approach: For that reason, many studies have been conducted to keep the high reliability and survivability of the MPLS networks. Unlike User Datagram Protocol (UDP), Transmission Control Protocol does not perform well in case of like-failure of MPLS networks because of its inability to distinguish packet loss due to link-failure. After the recovery time, TCP takes longer time than UDP to continue as it was before the failure. Results: In terms of packet loss, TCP performs better than UDP. However, the receiving rate of the TCP traffic is much worse than UDP traffic. A need for a mechanism to improve the behavior of TCP after a link failure is needed. This study focused on comparing the behavior of different types TCP as well as UDP traffic over MPLS networks in case of link, node or congestion failures. Conclusion: Although extensions of RSVP-TE protocol support fast recovery mechanism of MPLS networks, the behavior of TCP will be affected during recovery time much more than with UDP.
