NRO, the RIRs collective, is still working on this. It's listed as an open

It's very unlikely that ICANN, which sees the NRO as it's address support
organization, will move on this before NRO does.

Is your burstable bandwidth cost high enough to pay 100K for a gear
just to meet the commitments ? NAGIOS/CACTI monitoring alerts sent to
someone (which may be hired help from any place in the world) would
probably beat that in cost effectiveness.
The performance requirement is where a line is dra
Hi.
Are there solutions already available implementing 40GBASE-LR4,
100GBASE-LR4 and 100GBASE-ER4 draft standards ? By solutions it means
both switches with CFP-MSA/QSFP/CXP ports and the modules.

Manage Engine flow receiver with no user sessions viewing statistics
runs at 100% CPU for 200+ Mbps unsampled traffic. It's suited to SMBs
only.

My vote goes to proprietary ring protection from the vendor you choose:
- EAPS (Extreme)
- REP (Cisco)
- MRP (Foundry/Brocade)
- EPSR (Allied Telesis)
Although EAPS is implemented in all Extreme switches, select models
from the other vendors implement ring protection, but these models
also do othe

As IP traffic is assumed to be self-similar, my EE origins tell me to
look for parameters that could measure it from stochastic process
theory. On a Google search this paper sounded interesting:

On shared media like radio access, every unwanted packet means less
performance you will get out of the network. This can be done by NAT,
stateful filtering with public IPs or stateless filtering with public
IPs; the advantage of doing NAT is making it easier for the end-point
software to know that
Covad telling you they don't keep logs is different from them not
really having the logs... but, if they really don't keep logs, they

Besides the other solutions listed, you can also take a look at Arbor
