There is always someone claims his network could reach availability 99.9% or so, but I don't understand how a network availability should be measured or figured out. Is there any paper on this? Focusing on SLA of a network, ISP network or PoP site should not carry only one type of business traffic ( e.g. broadband access, MPLS-VPN, L2 VPN etc.), if we consider it simply by taking network as a single system optimization will surely be of no usage. Looking at PoP site , is there any recommendation on its design? a layer-2 access model is better than router based system?
