When you will look at the difference between mpls line vs leased line, you will understand that the Businesses today have multiple options when they need to establish connectivity between different offices. MPLS and Internet leased lines are two major alternatives evaluated against each other for such WAN connectivity in this article. While MPLS is deployed as a full mesh and is a unified data carrying solution, a leased line links two sites and is an end-user connection with predetermined bandwidth.
Wide Area Network (WAN) is an important component of corporate infrastructure for most businesses today. There are several technologies to connect multiple, geographically distant sites using WAN technologies. These include Ethernet, asynchronous transfer mode (ATM), frame relay and fibre broadband.
All of these have their own strengths and weaknesses, which primarily depend on the kind of traffic transmitted through them and the need for latency, security and reliability.
Leased lines, another common way to establish a symmetric telecommunication link between two sites, can be used for voice, data and Internet services. It offers a guaranteed and predetermined bandwidth between physically distant sites. The connectivity provided by a leased line is not shared with any other subscriber and the speed is therefore symmetric for both downloads and uploads.
MPLS line is a full mesh technology, providing point-to-point connection between multiple sites. It is highly secure and provides Quality of Service (QoS) to ensure that priority applications like VoIP are not affected by other lower priority applications. MPLS also allows for dynamic routing which makes it an ideal solution for traffic engineering.
While most of the older technologies including legacy leased lines had similar objectives, Multi-Protocol Label Switching (MPLS) emerged as a sound alternative to bring all of them into one cluster. It played to the strengths and negated the limitations of each of these technologies.
MPLS is essentially a packet switched data transmitting network technology that can transport numerous variations of traffic such as IP packets, as also native ATM and Ethernet frames. It is a better substitute for many other protocols and has a solution that calls for fewer overheads while delivering connection-oriented services for variable-length frames.
Replacing older connectivity methods at a fast pace, MPLS dispenses the signalling protocol and cell-switching gear of ATM. It also emphasises that we do not need ATM cells anymore in the hub of modern networks. This is because the networks used today are so quick that even full-length packets (measuring up to 1500 bytes) do not lead to real-time queuing impediments.
How Does MPLs Work?
When it comes to MPLS vs. leased lines, knowing the functionality becomes crucial. Every data packet in the MPLS set up is assigned a label. Also, this label is the basis of all packet forwarding decisions, and it alleviates all the need to evaluate the packet contents.
How Does It Work?
Now, to better understand MPLS vs. leased lines, get insight into how ILL works. As the name suggests, the internet leased lines are ‘leased’ by the business enterprises, thus, enabling bandwidth availability to the users.
Clients essentially rent these plans for enabling high-speed internet connectivity between the different locations. The internet leased lines are made of pure fiber optics, which helps them in delivering high-speed internet service. They function by sending across strokes of light via these cables. These transmitted data possess the capability to travel at the speed of light. Moreover, this leased line connectivity is not shared by someone else but only with the customer.
