5 Things To Keep In Mind in MPLS Vs VPN |
Posted: March 1, 2017 |
If we talk about establishing connectivity between offices or networks, there are several options to consider. However, the major question is whether to use a leased line, a VPN (virtual private network) or MPLS (Multiprotocol Label Switching). With all these three established connectivity, technologies differ. Lease lines are physical units. VPNs can be delivered over different layers of networks and MPLS is a network traffic routing mechanism that can also be used to provide VPN services. Here are five factors to consider if we talk about MPLS VPN. CostPrice is obviously a determining factor between MPLS and IP VPN. Lease lines are the most expensive in this series. VPNs are more affordable, and it remains available in different layers (most secure is layer 2 VPN, layer 3 VPNs are faster to install and cheaper). However, layer 3 VPNs are also prone to risks. MPLS are more efficient when it comes to rely on IP-based routing. SecurityIf we talk about security, leased lines win the debate as they are dedicated to a particular customer’s network. VPNs, if used over public internet, are least secure. Here, MPLS lies in the middle. It is not a dedicated line. Still, it depends on shared network element. ReliabilityOn terms of reliability, leased lines take a lead. VPNs may vary as traffic makes its way from one network to another. It shares a virtual route with other traffic. MPLS allows prioritize traffic routes and establish quality service levels. ScalabilityLease lines are the most challenging to scale as it needs time for installation. Expense is another factor. Layer 3 VPNs are easy to install, but it may become complicated to manage with the growth of business. MPLS here is widely accepted as an efficient technology that can be easily mapped. Need of operational dataThis factor includes the type of flowing data and requirements of business. Does the business need only point to point communication? Or, does it vary from point to multi-points? A network covering multiple locations must be capable enough to communicate with all others. In catering to the complex network needs, lease lines fail. MPLS are well provided with point to point as well as one to multiple capabilities for communication. These are some factors that clearly divide lease lines, MPLS and VPN.
