Cooperation with Brazil

["Paulo Rodrigues" <>]

Hi all,

 

I am presently a visiting scholar at UCLA but I shall be returning to UFRJ (University of Brazil, formerly Federal University of Rio de Janeiro) by the end of this year, where I manage a VOIP and Telephony over ATM and IP group at UFRJ Computer Center.

We have developed an H.323v1/SIP signaling gateway and also we have been testing a telephony over ATM solution called Sphere from Marconi. We are in the verge of interconnecting two PBXs (NEC NEAX-2400) across an existing  municipal ATM backbone (via circuit emulation at first step) and waiting for a H.323/PSTN GW solution soon (maybe Cisco based) to start playing with VOIP in a larger scale and maybe initiating some trunking experiments over the Internet.

 

As telephone is an expensive resource in Brazil (we have impulses every few seconds even for local calls), one of the midterm goals is to take advantage of the new high speed infrastructure being deployed and allow VOIP and Telephony over IP services nationwide, for universities and research community.

As I have been involved in activity planning for future joint US/Brazil Internet 2 cooperation, I believe that extending these goals to cover some international experiments is quite desirable and a way to explore QoS, MPLS and other traffic engineering solutions over our OC-3 international link.

 

A good starting point would be to get information on Internet2 VOIP testbed and identify institutions willing to establish telephony and VOIP experiments with Brazil.

 

If you have any contributions and pointers in the above directions I would deeply appreciate.

 

Wishful Thanks,
