Multi Protocol Labelling System (MPLS) – Why Important

Filed under: Network Protocols — admin @ 5:26 pm

Why is MPLS such a widely used networking technology

Multiprotocol Label Switching (MPLS) is a technology designed to divert or route network traffic around congestion and failures, therefore it speeds up network traffic flow. Without any involvement from the user, it makes it easier to manage. It’s called multiprotocol because not only does it work with the Internet Protocol (IP), but also with various other network protocols and ATM. Wireless service providers use this piece of technology because it improves quality of service. Not only that, it also minimizes delays and it helps keep things on track with customers, in terms of service level agreements.

MPLS plays a strong role in improving network performance without companies or individuals spending or investing.

One of the significant functions of MPLS is that it provides new capabilities in 4 important areas:

  • Quality of service (QoS),
  • Virtual Private Networks (VPNs),
  • Traffic engineering, and
  • Multiprotocol support.
  • It is a technique that is popular and readily adopted for the reason that it’s effective. A lot of networks are dealing with increased mixtures of traffic nowadays. For instance, if you have a client that needs to provide streaming video and audio to their customers online. Also those companies that require a lot of bandwidth for their online processes, or those Internet entrepreneurs or individual businesses that need a reliable Internet connection?

    MPLS provides network operators a lot of flexibility to divert traffic around congestion and bottlenecks, and it’s fast and cost-efficient, thus providing an excellent solution to most Internet network problems.

    Although MPLS is a secure technology, it is still essential for users of internet services to be aware of security issues and take precautionary steps to protect their networked systems.

    Carrier Ethernet for Mobile Backhaul: Background

    Filed under: Carrier Ethernet,Metropolitan Ethernet Networking — admin @ 10:47 pm

    The Metropolitan Ethernet Forum (MEF)[1] has been a major focal point in the move towards Ethernet in the MAN scope. Several documents available from the MEF, and information from industry presentations in a number of places provide details of how Ethernet can increase the efficiency of network communications outside a LAN environment.

    Delving into this information allows us to see how Ethernet would be deployed in a wider networking scope, and expected benefits.

    This is one of a series of articles published at infrastructurecomputing.com looking at the possibilities of Ethernet in Metropolitan Area Networks (MAN).

    Synchronous Ethernet for Transport Synch

    In an article, “Synchronous ethernet: a method to transport synchronization“, by Ferrant, J.-L.; Gilson, M.; Jobert, S.; Mayer, M.; Ouellette, M.; Montini, L.; Rodrigues, S.; Ruffini, S.
    published in Communications Magazine, IEEE, Vol. 46, Issue 9, September 2008, the authors discuss the evolving transport architecture, covering some of the synchronization distribution problems to many endpoints where mobile backhaul and TDM emulation occur.

    From this article, it would appear that synchronous Ethernet suits both the Ethernet and synchronization architectures, which has partially enabled development in standardization bodies.

    Further development in Synchronous Ethernet standards is being directed at enabling interworking with and migration from existing SONET/SDH-based transport infrastructure.

    From research reports and comments appearing in a number of places, it appears that Synchronous Ethernet will  not be subject to the normal packet delay variation and traffic load conditions that can occur in packet based networks. Research results are being made available which show that Synchronous Ethernet can achieve  a very high level of performance, which will lead to highly robust system implementations. It is intended to summarize some publicized research results in later posts.  Any reports or information relating to further research outcomes relating to Synchronous Ethernet would be welcome.
