The next generation communication system will provide high quality multimedia service in a more flexible and intelligent manner. In this paper, we propose a new SIP over MPLS network architecture to achieve this goal. To integrate SIP protocol with the traffic engineering function of MPLS network seamlessly and facilitate SIP call setup, the SIP-MPLS traffic aggregation server (TA server) is hi...

Abbildung 1: AH und ESP im Transport-und Tunnelmodus (vereinfachte Darstellung) Der Transportmodus hat den Vorteil, dass jedem IP-Paket nur wenige Bytes hinzugefügt werden. Demgegenüber bietet der Tunnelmodus eine höhere Sicherheit, weil das gesamte IP-Paket authentifiziert bzw. verschlüsselt wird.on Authority (RA) und Certificate Authority (CA) zusammen, die in einem Trust Center angesiedelt s...

This paper addresses the problem of designing a capacity management/traffic engineering procedure for an IP/MPLS over ASON/GMPLS scenario. We suggest TRIDENT, a procedure whose main goal is to dynamically provide the bandwidth required to transport through an ASON the MPLS–LSPs already established at the IP/MPLS client network. TRIDENT relies on automatically triggering demands to set up or tea...

Data center interconnectivity is particularly very important and essential for emerging applications such as cloud computing and financial trading. Current data center architectures are built using Ethernet switches or IP routers both with significant cost and performance deficiencies. We propose for the first time, extending MPLS-TP into the data-center. To this end, a new look-up protocol for...

ABSTRACT: MPLS is a promising technology which provides efficient routing and high speed switching. In recent years, emerging internet applications demand for high quality of service (QoS) guarantees. This paper mainly focuses on protection of data flow over MPLS network in case of any failure occurs in node/link. Network survivability can be affected by the faults in MPLS network. Existing app...

MPLS (Multi-Protocol Label Switching) and DiffServ (Differentiated Services) provide means to implement various QoS types in IP networks. While MPLS enhances the classical IP networks by supporting efficient connection control through explicit label-switched paths (LSPs), DiffServ allows differentiated QoS parameters commitments to be supported on the same IP backbone for different classes of s...

The WWW has been the preferred technology used to provide information and e-services over the Internet. However, one major limitation of Web servers is that they treat all requests equivalently, without using priority schemes or different levels of service. Various methods to introduce such differentiated service are possible. MultiProtocol Label Switching (MPLS) can be an useful tool to extend...

IP (Internet Protocol) has been traditionally routed over ATM (Asynchronous Transfer Mode) via Virtual Circuits (VCs) or Multi-Protocol over ATM (MPOA). These methods proved to have a complicated operation mode; therefore, the necessity for a simpler method is required. All these necessities can be supported by the Multi-Protocol Label Switching (MPLS) since it integrates the most important cha...

PTIT, Ho Chi Minh 1 This paper presents the ability to quickly reroute traffic around error or congestion in a Label Switched Path (LSP) of MPLS networks. When label switched path established unusable (e.g. due to a physical link or switch failure) data may need to be re-routed over an alternative path. This paper include 5 parts. Part 1 introduce the essential of alternative path in MPLS when ...
