Tier 1 ISP
What was SPNP?
It is important for a quality-of-service concept to develop and
implement a price model for the interconnection between
different networks that is not only volume-based but also
explicitly quality-based. …
Since the permanent implementation of defined quality
parameters causes higher costs than best effort traffic, a network
operator will only guarantee this quality if the forwarding network
pays appropriate prices which are higher than those for besteffort. ….
The individual “original ISP” will bill its customers accordingly. The
commercial service and content providers will send the majority
of all QoS data packets, so they will also bear the bulk of the
(Kruse (2008) Network Neutrality and Quality of Service, Intereconomics, January/February, pp.25-30.
Perpetuating an 'unpaid peering' approach for IP Interconnection that developed
when traffic patterns were largely symmetric can hamper the incentive to invest in
transport capacity and network quality.
By proposing a charging principle that is well tested and has delivered efficient results
ETNO is not trying to bring back the circuit switched architecture of the PSTN. The
main aim is to promote , where appropriate, a charging principle which re‐aligns costs
and revenues by assuring that the agents are accountable for the costs they incur.
The sending party pays principle would not be imposed but commercially negotiated.
If “bill & keep” were to be replaced by SPNP then the ISP providing access could
exploit the physical bottleneck for traffic exchange and derive monopoly
profits, requiring regulatory intervention.
ETNO’s proposed end-to-end SPNP approach to data transmission is totally
antagonistic to the decentralised efficient routing approach to data transmission
of the Internet. The connection-oriented nature of end-to-end SPNP, with its
focus on charging based on the actual volumes or value of the traffic, would
represent a dramatic change from the existing charging framework operating on
Finally, it is worth pointing out that ETNO’s proposals do not seem to have taken
account of the fact that the request for the data flow usually stems not from the
CAP but from the retail Internet access provider’s own customer (who “pulls”
content provided by the CAPs, and from whom the ISP is already deriving
