Our current solution is to use ipsec/gre tunnels traversing over the Intern= et. The specific needs the new solution must meet are: - The ability to run end-to-end QOS. - Dedicated bandwidth - Support 1gbps transfer rates - Enable communication between 3 locations The options I have looked into so far are: - Layer 2 Ethernet (Virtual Private Line): This service seems to be offered= by a lot of ISPs using various networking techniques. The price point is a= ttractive however packets are forwarded only at best effort across the ISP'= s network which means the quality of the service will directly reflect the = ISP's network performance. - Traditional Leased Line (dsX/ocX): This service seems to be more expensiv= e then wavelength services however meets my needs. - WaveLength Services (oc3-10gig): This service seems to be cheaper then tr= aditional leased lines when comparing similar bandwidth. However, availabil= ity is limited to on-net buildings. This solution meets my needs. - MPLS based VPN solutions: Seems to be a good point to multipoint technolo= gy with QOS offerings. However, the price seems to be around the same as wa= velength services for the amount of bandwidth we require. If the number of = data centers we were looking to connect was larger then this option would b= e more attractive. This solution meets my needs. Based on my needs and what my options are I am leaning towards point to poi= nt wavelength services connecting my 3 locations in a loop like fashion. Are there any other options I should consider? Are my descriptions of the today's possible solutions inaccurate? Are there any thoughts on today's pricing that differs then my findings? Thanks Chris Kleban
