The use of the Internet has become very important in our daily life. Therefore, the quality of the network is becomes very important. There are several protocol and technology in the Internet network. In this paper we analyzed Multi-Protocol Label Switching (MPLS) compared to Non MPLS. We compared the throughput, packet loss, and Jitter. We used the tools such as Iperf, Wireshark and routing table...
Traffic Engineering is an efficient tool to balance the network flows and, thus improving the network performance with limited network resources. The goal of traffic engineering is to find an efficient and robust routing to balance the flows with changing traffic. Multiple traffic matrices are good representatives of the changing traffic. The emergence of Software Defined Networking (SDN) provides...
Method for calculating routing cost of MPLS network is presented in the work. This method allows to minimize routing cost, taking into account traffic fractal properties, choice of traffic transmission path and quality of service requirements. The method uses values of the Hurst parameter and value of normalized spread of traffic values, which makes it possible to apply it to self-similar and multifractal...
Segment Routing (SR) has been recently introduced to enable efficient traffic engineering while simplifying control plane operations. Thanks to the source routing paradigm, traffic flows can be dynamically routed along the network, effectively exploiting network resources. In this paper, dynamic SR operations for multi-layer networking are presented and experimentally demonstrated. In particular,...
Multicast forwarding in the context of IP-MPLS networks for services like VPLS has important scalability issues. Alternatives to per-VPLS tree construction based on aggregation of multipoint requests onto shared trees have been studied. Other works have focused on stateless forwarding based on Bloom filters. Both suffer from some type of forwarding anomalies. This paper proposes the combination of...
With constant evolution of the Internet, many of its even well-established properties continue to change. This study re-evaluates the stability and diversity of Internet paths and whether it is affected by the widely deployed Multi-Protocol Label Switching (MPLS). In particular, using traceroutes between large number of source-destination pairs with the Internet Control Message Protocol (ICMP) extensions...
This paper describes a centralized routing algorithm based on permutation of M traffic flows entering the network. The proposed approach is significantly less complex than combinatorial approach and can be used as load-balancing tool. The main advantage of such approach is that many non-perspective flow permutations could be eliminated from the calculation very early. If a new flow enters the network...
Virtual Private Networks (VPNs) implemented by Multi Protocol Label Switching (MPLS) tunnels appear in the service offer of many Internet Service Providers (ISPs). Due to the number of technologies that they involve and to the intricacy of their interactions, provisioning, setup, and maintenance of VPNs is a cumbersome task, whose complexity is usually mitigated by using advanced network management...
Energy consumption has become a limiting factor for deploying large-scale distributed infrastructures. This work1 seeks to improve the energy efficiency of backbone networks by providing an intra-domain Software Defined Network (SDN) approach to selectively turn off a subset of links. We propose the STREETE framework (SegmenT Routing based Energy Efficient Traffic Engineering) that dynamically adapts...
Today's over the top (OTT) video service providers take advantage of content distribution networks (CDNs) and adaptive bitrate (ABR) streaming where a video player adjusts resolutions based on end-to-end network conditions. Although the mechanisms are useful to improve user-perceived video quality, they do not resolve the root causes of congestion problems. To pinpoint a bottleneck and improve video...
Guided by the concept of the next generation broadcasting, China's broadcasting network is undergoing a migration from the DVB based system to an all IP-based one so that triple-play services can be delivered to enhance the competitiveness of the Chinese broadcasting service providers. This change happens primarily to the backbone networks, which are IP/MPLS based. The integrated services will introduce...
MPLS (Multiprotocol Label Switching) is one of the possible methods used to create a data circuit switching behavior even if the underlying telecommunication network is a routed/switched packet network. If inside the network there is a path hierarchy, the common approach is to transmit the entire label stack, using one label for each path in the hierarchy. For optimization, a single LSP (Label-Switched...
We consider the problem of providing network protection that guarantees the maximum amount of time that flow can be interrupted after a failure. This is in contrast to schemes that offer no recovery time guarantees, such as IP rerouting, or the prevalent local recovery scheme of Fast ReRoute, which often over-provisions resources to meet recovery time constraints. To meet these recovery time guarantees,...
In VANET networks, V21 communication is a way of making better useshared resources and leverages services provided through access RSU (Road Side Units) deployed on roadsides, This mode is inadequateapplications related to road safety because the network infrastructure are not performing as to delivery times. MPLS is heavily taxed proving the most appropriate solution for migrating to converged networks...
Since conventional routing algorithm is easily leading to the problem that some segments of a network are quite congested while other segments along alternative routes are under utilized, this thesis proposed a new load balance algorithm called load balance algorithm using deviation path. Multiple Protocol Label Switching (MPLS) uses its explicit routing technology to implement traffic engineering...
Most single-packet IP trace back approaches that have been proposed demand routers to log the packet digests to trace back, which lead to the linear growth of the storage overhead as the forwarded packets are increasing. This paper proposes a novel single-packet IP trace back approach based on the routing path to alleviate the burden of routers. Our approach introduces the relevant theories of label...
In this paper we show data plane restoration measurements for restoration under backbone link failures for a large network with IP/MPLS OSPF routing and also for the same backbone with Traffic Engineering (TE) and Fast Reroute (FRR) deployed. Our study is unique as we analyzed a significant quantity of measurements obtained from a production network over a 14-month period encompassing many link failures...
As a result of the higher speed of bandwidth communication link, routing forwarding node is drawing us more attention. IP switching technology has been approved on the basis of the various analysis of the IP switching technology. We can get the three-layer IP routing technology system, which can bring us the shorter interval while transmitting dates and enhance the stability to support the transition...
Multiprotocol Label Switching (MPLS) [3] is a protocol widely used in commercial operator networks to forward packets by matching link-specific labels in the packet header to outgoing links rather than through standard IP longest prefix matching. However, in existing networks, MPLS is implemented by full IP routers, since the MPLS control plane protocols such as LDP [8] utilize IP routing to set up...
In this paper, we propose a high-speed packet transmission mechanism using source switching label information. In the proposed mechanism, switches within core network can simply switch packets to next port using source switching label information since ingress nodes transmit packets inserting the end-to-end path information in label header. Unlike MPLS (Multiprotocol Label Switching), it is unnecessary...
