30 years ago...

We had one telco

They had some services

They sold the end equipment Most fascinating service was call forwarding

when there was no answer

The telco was responsible for everything, andlegislation was written to target only them And, they where owned by the government

20 years ago

We started to get competition

First political decisions where made thatsaid that competition was to be enabled Number portability

More than one company selling phones More than one cellphone provider

Today a different world

Many telcos

Competition regarding new services Not only telephony uses telco equipment Internet has taken off

With Internet, global reach at zero cost Globalization is here

Computers and Internet

Everything is in the future a computer, a networkedcomputer of course!

At its simplest your TV, your phone, your addressbook, your agenda, your micro-wave, you car, your... andyour laptop are all networked computers

The Internet belongs to all of us - or at least we allown a bit of it

Each of us has our own personal Internet and some ofit we may choose to share Increasingly each of us runs part of the infrastructure

Convergence?

Information = Software

Anyone can create Information Anyone can create Software

Anyone can distribute Information

Anyone can deploy Services

My piece of the Internet?

When a person or organisation connect to

the Internet, the network and servicesprovided end up being a piece of theInternet

Protection (and robustness) start at home

You have a lock on your door, and do not askroad authorities to keep burglars out!

Interconnection The connection of Service Providers in order to exchange traffic

between them

Inter-Service Provider IP Backbone

The collection of interconnected GRX and IPX Providers

networksIP Backbone Provider A business entity that provides Inter-Service Provider IP Backbone

Service. Either a GRX or an IPX/GRX Provider

Interworking The ability for a service offered to subscribers of one network to

communicate with a similar service offered to subscribers of adifferent network

IPX IP Packet eXchange. The entity providing the IPX functions. In theinterconnection context, IPX is used to mean an interconnection atthe service level. Also refers to the collection of all theinterconnected IPX Providers networks

IPX Provider A Provider that offers IPX services and may also offer GRX

services

MMS Multimedia Messaging Service

MNO-G A GPRS/UMTS Mobile Network Operator that connects only to a

GRX Network. The services they offer over the GRX network are ona bilateral basis with no guarantees of QoS end-to-end

MNO-I This Service Provider is a GPRS/UMTS Mobile Network Operator

who connects to either a GRX and IPX network or an IPX networkonly.

and transit connectivity models described above, where they facilitate a Service Providersconfiguration and agreement management and the cascading of charging.

The different types of traffic may require processing by separate proxies functions availablewithin the Inter-Service Provider IP Backbone. It is an implementation issue whether thesefunctional entities will be separate or combined into one network node.

Figure 3 - Proxy in Inter-Service Provider IP Backbone

Figure 3 above shows the high-level architecture of bilateral Service Provider traffic traversingthe Proxy element within Inter-Service Provider IP Backbone using any type of IP based traffic.The user plane may or may not go through the proxy depending on each service requirement.

5.6 Types of Service Provider and Interconnectivity Allowed

There are three different types of Service Provider. They are classified according to the type(s)of IP Backbone Provider(s) they connect to. This section describes each type and the

!Performance critical NGN-type services cannot be routed via GRX networks whereQoS policies are not enforced

!MNO-G type Mobile Networks are protected from malicious attacks originating fromNGNO networks and vice versa.

!MNO-I type Mobile Networks can optionally be protected from malicious attacksoriginating from NGNO networks.

6.5.4 IP Addressing

Internet routers should not be able to route to the IP addresses advertised to the Inter-ServiceProvider IP Backbone. The IP Backbone Providers and Service Provider networks shall be

totally separated from public Internet, from an IP routing perspective.

Currently, Inter-Service Provider IP Backbone networks use IPv4 addressing and there is noplan to introduce native IPv6 addressing in the foreseeable future. It is intended that IPv6 issupported by tunnelling the IPv6 traffic over IPv4 between Service Providers where required.

Both IP Backbone Providers and Service Providers who employ IPv6 in their network shouldassume full responsibility for all network adjustments necessary for maintaining connectivity to

all other IP Backbone Providers and/or Service Providers that deploy IPv4.

An IP Backbone Provider is responsible for the denial of IP spoofing attacks originated by itsService Provider customers, i.e. only traffic from valid IP address ranges is allowed to flow toother customers or other IP Backbone Providers.

Next 30 years?

Consumers will choose themselves Services must be reachable from everywhere

We will see fewer service providers, not more Internet will carry every information service Consumers will pay for Internet access

New processes will help people go green All discussions around NGN and oldbusiness models will (finally) be dead, but it willbe a blood bath
