Bi-Lateral Vs. Multi-Lateral
TDMMinutes
ISP
VoIP
Bi-Laterals: TDM wholesale voice minutes transactions implies a commercial relationship – typically wholesale
termination between 2 parties
No such thing as Multi-Lateral in TDM since there is no “peering fabric” and every TDM minute has a $
Value
Off-sets: closest thing to “peering” in TDM minutes an agreement where bi-lateral debts negate one another occurs at Layer 2 in the non-analogous OSI model
Bi-Lateral Vs. Multi-Lateral: TDMMinutes
ISP Peering: interconnecting at Layer 2
Bi-Lateral Peering: directly between 2 parties who agree to connect
typically a “free” exchange of IP traffic occurs on a Public Peering Fabric or via a Private Peering
Interconnect (Loop, Cross Connect)
Multi-Lateral Peering: Multiple parties all agree to send and receive traffic with each other via a Peering Fabric
typically a “free” exchange of IP traffic some instances include “paid peering”
• costs less than IP transit• costs more than “free”
Bi-Lateral Vs. Multi-Lateral: ISP
VoIP Peering: The interconnection of two, or more networks Several definitions at Layers 2, 3, 5 and 7
Layer 2 Peering: through a common Ethernet switch most similar to traditional ISP peering distributed peering is possible
Layer 3 Peering: VoIP interconnections through the public Internet gateways interconnecting through the cloud usually wholesalers avoiding TDM transport
Layer 5 ENUM: can occur through both the Internet and an Ethernet Fabric
ENUM – Bi-Lateral and, or Multi-Lateral
Layer 7 SIP: can occur through both the Internet and an Ethernet Fabric
SIP Peering - Bi-Lateral
