Difference between MPLS and GMPLS

Both MPLS and GMPLS are closely related terms, hence it is easy to get confused between the two. This article will explore all the key differences between MPLS and GMPLS. Before exploring the dissimilarities, let us first understand the concept of MPLS & GMPLS and how they operate. 

How does MPLS work?

MPLS stands for Multiprotocol Label Switching. It is a protocol that shapes and speeds up network traffic flows. MPLS forwards packets at Layer 2 which is a switching level, rather than Layer 3 which is the router level. The key function of the MPLS is to tag the internet traffic with a label in order to distinguish the Label Switched Paths or LSPs. Once it tags the traffic, it determines the best link to forward the packets along with the label to use on the next hop. MPLS uses a different labels for each hop which is generally chosen by the router. This allows the implementation of simple and fast forwarding engines which are often executed in the hardware. 

How does GMPLS work? 

GMPLS stands for Generalized Multiprotocol Label Switching. The GMPLS is conceptually similar to MPLS. However, it used as a physical property of data stream to comprehend which LSP it belongs to instead of using an explicit label to distinguish a Label Switched Path LSP at each Label Switched Router LSR. 

GMPLS is also used to establish Label Switched Paths for circuit traffic in addition to packet traffic. It uses the Time Division Multiplexed (TDM) link and Wavelength Division Multiplexed (WDM) link to switch traffic on a continuous basis. This leads to well-organized application in the data plane with no per-packet lookups. Hence GMPLS is an ideal protocol to operate high bandwidth networks. 

MPLS and GMPLS Protocols

With MPLS only the forwarding mechanism is defined, therefore it uses other protocols to establish Label Switched Paths (LSPs). This task is performed by two separate protocols i.e. a signaling protocol and a routing protocol. Moreover, static provisioning can also be used establish MPLS LSPs. This can be done by configuring each network element with the appropriate transit/ingress/egress information.

MPLS and GMPLS Routing Protocols

The main function of the routing protocols is to distribute network topology information from the network so that the course of an LSP can be calculated automatically. Generally, interior gateway protocol, such as OSPF or IS-IS is utilized. This is mainly because MPLS networks normally covers a single administrative domain. Traffic engineering (TE) extensions are used to avoid any single point of failure and establish LSPs with guaranteed QoS characteristics.
