RESIDENTIAL USER VIEWPOINT


A FUTURE WITH NEW POSSIBILITIES

> Home networking> Personal communications

• Integrated telephone system• Videoconferencing

> Online gaming> Multimedia streaming

• Radio service• Television service• VoD

> Network integration• FMC• Collaborative networks

> Added value services• Home automation• E-care


ROUTERS PROMOTED TO GATEWAYS

SO…..

> ‘Broadband’ is a term that has been used for a long time• In home and core networks it has been consolidated• In access networks it was just marketing….

> Now broadband is really reaching the residential environment• Several Mbps are now reaching users’ houses• New services are being offered to promote faster penetration

– P2P is the killer application so far

> However it is not just broadband what matters• In order to succeed some technologies have to be adapted into the

new framework• Provision of QoS, authentication, homogeneous signaling, etc.


TECHNICAL CHALLENGES EXAMPLES

> QoS

> FMC

> Signalling

> NAT

> Authentication

> Multicast

> Management

CLICK! MODULAR ROUTER

> Click! is a modular software-router developed by MIT.• Now supported by:• Web site http://www.read.cs.ucla.edu/click/

> There are two ways to run Click:• At the application level: only receives frame copies• As a Linux kernel module: this is it!!
