VPLS and RPR

I am getting a lot confused on proposing VPLS or RPR for the metro solution. Can anyone guide me on the plus and minus or comparisons on VPLS and RPR technologies ????

Some links could be really usefull.

Thanks in advance

Re: VPLS and RPR

Based on my understanding, VPLS and RPR cannot be compared to each other since they are two different technologies to perform different functions although these two technologies can work hand in hand. VPLS would give you ethernet multipoint connectivity across many packet-switched technologies. RPR/ Resilient Packet Ring I believe would give you resiliency in the network with theoretical response of 50ms-200ms in fail-over as compared to ethernet technologies like RSTP, STP and Cisco's DPT.

Re: VPLS and RPR

hi,

But i thought both compete each other when asked the basic question what technology one wants to deploy when planning for a metro network. Even service providers are inviting solutions with option A of vpls or option B of RPR when deploying new networks.

But as you pointed out I too couldnt get hold to something which compares both, so i presume that could be either both cant be directly compared or my search engine is dying ;-)

Thanks for the reply

Re: VPLS and RPR

In my opinion, it would be best if it'll have RPR for resiliency and fast-failover. VPLS if your customers would later require ethernet multipoint connections in the future. I would like to have all my links to have RPR/DPT if possible because I don't want downtime.
