Critical questions in a multi-operator network

1. How can a deal be made between different operators, with different services, without putting a new cost structure upon the operators?

2. What is the required critical mass (in terms of end-users) to support multiple operators and ISPs?

Cash flow schemes – the basics

Network Owner -> Operator

Operator -> Service Provider - Connection fee per user and connection

depending on service.- Monthly fee per user and service.- Example of another fee, depending on

specific case, is an establishing fee for the ISP/Service.

Service Provider -> Customer- Same as above plus margin and other fees.

Scenario 1

Ring TopologyAll the networks connected to their

neighbors forming a ring.

Pros and Cons…..

Easier and cheaper to implement.

Not scalable and not optimal.Many more problems with business

Scenario 2

STAR TopologyThe networks and the service providers connectedto a central exchange point.

Pros and ConsOptimal Solution. Very scalable. Easy to implementin the given networks.With SOLIX, the expenses are not high forimplementation.

Introduction to Solix

- SOLIX is a internet exchange operated partially by KTH.- Has a backbone which can form the central structure in STAR topology.- Is reliable and industry trusted.- Easy for technical solution implementation.- Is scalable.

Solution

- Concentrate on STAR topology.- SOLIX is the center of exchange.- The concept of Virtual LANS will be utilized.- Kista IP and OpenNet networks to be connected as a test bed.- Future general solution depends heavily on the test bed.
