Actually, it is not true that Layer 2 Ethernet is 'best effort'.=20
It depends.=20
There are Layer 1 Ethernet products that involve no Layer 2 switching or =
Layer 2 routing, just an efficient and transparent mapping of Ethernet =
into SDH/SONET.=20
And some of those products can be upgrade in 50 meg increments from 100 =
to 1,000 megs.=20
After you have outgrown your GigE, then you can migrate to a LAN PHY 10 =
GigE link using affordable LAN interfaces and keeping your network =
'untainted' by SONET/SDH.=20

Hello Nanog,
I'm currently looking into what are the options for enabling =
inter-datacenter communication.
Our current solution is to use ipsec/gre tunnels traversing over the =
Internet. 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 attractive 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 =
expensive then wavelength services however meets my needs.
- WaveLength Services (oc3-10gig): This service seems to be cheaper then =
traditional leased lines when comparing similar bandwidth. However, =
availability is limited to on-net buildings. This solution meets my =
needs.
- MPLS based VPN solutions: Seems to be a good point to multipoint =
technology with QOS offerings. However, the price seems to be around the =
same as wavelength 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 be more attractive. This solution meets my needs.
Based on my needs and what my options are I am leaning towards point to =
point 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
