Question on 95th percentile and Over-usage transit pricing

Hello NANOG, I have a fundamental question regarding 95th percentile pricing. I will make some prerequisite assumptions to set $/Mbps values before posting my actual question. Eg., For 1Gbps commitment, I will pay roughly $3/Mbps. Similarly for 10Gbps, 100Gbps I may pay $2/Mbps and $1/Mbps. This appears like a sub-linear economy of scale pricing model followed in transit pricing. Now if I commit 1 Gbps over a 10Gbps provisioned link, I will pay fixed monthly fee of $3000 for the 95th peak not exceeding the committed rate of 1Gbps. Now if my 95th peak is above the committed rate, say, 2Gbps or 4 Gbps or 8 Gbps, I believe I have to pay: $3000 + [over-usage_bandwidth_charges] monthly. Question: Does this over-usage bandwidth charge a linear cost function or is it sub-linear like the committed bandwidth pricing? I mean, will it cost me the same $/Mbps as over-usage charges for all 2Gbps, 4Gbps and 8Gbps 95th percentile peaks? or is it Over-usage_charges(2Gbps) > Over-usage_charges(4Gbps) > Over-usage_charges(8Gbps) ? I will be grateful for the replies! With regards Pradeep Bangera Research Assistant Institute IMDEA Networks Madrid, Spain
