Aggregation benefits
BIX.BG (public peering) is VERY FINANCIALLY EFFECTIVE FOR SET UP OF NUMEROUS PEERING SESSIONS with comparatively small peering partners with fixed costs per port and NO INCREASE OF THE COST when new peers are added.
Private Peering provides at least one separate physical port for every peer, rental of lines, taxes for cross-connections and other. Usually the traffic with many of the peers varies with large inclinations and with private peering all the physical connections have to be circumspect according to the maximum quantity of the traffic. The total volume of the traffic for every member is stable and variations are limited to the boarders of the actual peers. With BIX.BG the whole traffic passes through one port and the fluctuations of the traffic volume to the different peers do not demand change of the network.
For companies which exchange relatively large traffic volumes it is MUCH MORE CONVENIENT TO USE 10GE PORTS OF BIX.BG.
For Private Peering one should use the relatively expensive 10Gbps ports for both peers or should build several 1Gbps lines, which is sometimes technically inconvenient and certainly expands all expenses.
With Private Peering if the traffic between two peers reaches 1.1Gbps there should be an increase of the speed to 10Gbps, which is extremely expensive as an investment in equipment that is not effectively used. Another possibility is to create one more 1Gbps connection, which means that two additional ports, new physical line, and new cross-connections will be needed. Do not forget that the above actions need cooperation of both sides of the peering. Due to the aggregation of traffic, through BIX.BG an investment in one 10Gbps port can provide traffic for much bigger number of peers without having new 10Gbps port for each one.
