Multiprotocol Label Switching (MPLS)


As the name suggests, Multiprotocol Label Switching (MPLS) is a protocol, which is used to shape a network's traffic flow and intensify its speed. It enables several packets to be transferred at the switching level that is Layer 2 instead of them having to be sent up to the routing level, better known as Layer 3. The ingress router labels every packet that forays into the Internet Service Provider’s (ISP) network. As per the labeling, the succeeding routing switches then forward the packets. After this step, the egress router takes over operations and proceeds with forwarding the original IP packet to its destination by discarding the labels.

Devices operating as egress or ingress routers are generally referred to as Provider Edge (PE) routers. On the other hand, ones functioning solely as transit routers have received the title of Provider (P) routers.  It is important to note that the labeling plays a vital role in determining the path that will be followed by the packet. These paths, which are referred to as label-switched paths (LSPs), enable service providers to determine beforehand the ideal way for specific types of traffic to be directed within a public or private network.


About MPLS
MPLS functions via the frame relay and Internet Protocol (IP), Asynchronous Transport Mode (ATM) network protocols. Its naming was largely influenced by this association. Moreover, either of these protocols could be employed to form a label-switched path. The idea behind its creation back in the 1990s was to save time that routers would otherwise have spent in installing and reviewing routing tables. Contrary to popular belief, MPLS is not only applicable to private networks but also to several provider networks such as the Internet backbones. In recent times, MPLS is extended by Generalized Multi-Protocol Label Switching (GMPLS) to operate lambda switching, time division multiplexing (TDM), and different types of switching technologies apart from packet switching.


How MPLS can be used
Service providers may derive multiple benefits when using MPLS. When the LSPs, which are capable of meeting particular service level agreements (SLAs) on packet loss, traffic latency, jitter, and downtime, are defined by service providers, they could succeed in enhancing the quality of service (QoS). MPLS encourages traffic separation and even supports the formation of virtual private LAN services (VPLS), virtual private networks (VPNs), and virtual leased lines (VLLs).


Opt for MPLS services by reputed providers like Tikona Infinet, TikonaDigital NetworksEnterprise Services arm. With MPLS, service providers may benefit from the elimination of cell tax and the reduction in the number of networks that require management. The best part about this is that the user address space does not face intervention from MPLS. Therefore, users have the option of maintaining their addresses or even utilizing private (net10) ones. One of the reliable service providers, Tikona Infinet of Tikona Broadband offers MPLS services on its VPN backbone.

Stringent network design ensures the security of MPLS networks, which although a challenge, is not difficult to accomplish. However, MPLS is certainly a boon for service providers as they have better control over their networks, which consequently enables them to offer quality services to users.
