However, there VPLS tends to be marketed at an attention Overheads, for example, will have to include are key operational differences between the grabbing, affordable price.

But it’s one of the most topical and one of the most important. A wires only service is precisely that but many So with VPLS marketed as the next big thing we businesses fail to plan for the hidden costs ask ‘is it?’ And ‘is it right for you?’ that will inevitably follow further downstream. In some respects it’s a case of ‘read the small print.’ vPLS is in fact Layer 2 technology and has been available in various iterations for many years. It runs over mPLS which is Layer 3 and altogether more flexible. So which is the newest and which is best? Well, let’s again put the acronyms to one side and focus on some straightforward business considerations to assist decision making.
  4. 4. RELIABILITY BEYOND THE WAN In a climate where business continuity and In an age of austerity it is sometimes too easy So is there a solution in vPLS? Yes. But drill system resilience is all important, consider too to ‘knee-jerk’ to the marketing message of into the detail and really understand how the fact that vPLS relies on static routing.
