CGI.br
The Brazilian Internet Steering Committee (CGI.br) purpose is for coordinating and integrating
all Internet service initiatives in Brazil, as well as promoting technical quality, innovation
and the dissemination of the services available. The CGI.br is comprised of members from the
government, the corporate sector, the third sector and the academic community, and as such
constitutes a unique Internet governance model for the effective participation of society in decisions
involving network implementation, management and use.
NIC.br
The Brazilian Network Information Center (NIC.br) is a non-profit civil entity that implements
the decisions and projects designed by CGI.br.
CEPTRO.br
The Center of Study and Research in Network Technology and Operations (CEPTRO.br) is
responsible for services and projects that aim to improve the quality of Internet in Brazil,
working more specifically with Internet infrastructure.
PTTMetro/PTT.br is part of CEPTRO.br activities.

PTTMetro – Brazilian Metropolitan IXP Project
PTTMetro (PTT- Internet Exchange Point) is the project of the
Brazilian Internet Steering Committee (CGI.br) that provides the
necessary infrastructure for the direct interconnection between the
diverse networks that operate in a metropolitan region.

PTTMetro – PTT.br – Project # Operation
PTTMetro
CGI.br project started in 2004 and is still active.
PTT.br
Operation division responsible to deploy and maintain PTTMetro locations.
PTT.br has a partnership to support its operation with entities that host PIX
on all locations. Not complete list of PIX's hosts types:
● National Education and Research Network (RNP)
● Academic (e.g. Universities)
● Information Technology Government Companies (e.g. Procempa, Prodest, Prodepa)
● Internet Data Centers (IDC)
● Internet Service Providers (ISP)
● Internet Network Providers (NSP)

PTTMetro/PTT.br – IXP Locations
All PTTMetro Locations are Isolated
The main purpose for PTTMetro locations is to allow the local traffic to
stay in the location.
The Brazilian Internet Steering Committee do not intend to interconnect PTTMetro
Locations and compete with telecommunications companies.
PTTMetro project stimulates and support inter locations transport services done
by participants companies.
PTTMetro have defined some transport modes in order to optimize common
resources and reduce costs that are already in production
(e.g. Campinas <=> São Paulo by Fasternet company)

PTTMetro/PTT.br - Financial Model HighLights
PTTMetro / PTT.br costs are sustained by CGI.br / NIC.br, despite
Autonomous Systems (AS) participants needs for ports (number and capacity).
Each participant AS has only costs to reach one or more Interconnection Points (PIX)
of a specific PTT.br location in order to access its peering fabric.
There is no startup and recurrent fees for AS participants at all PTT.br locations.
18
PTTMetro/PTT.br – Operational Responsibilities
NIC.br
PTT.br is responsible for:
Installation, Management, Administration, Monitoring and Supporting all IX locations.
Always keeping Neutrality and High Quality as main targets.
Highlight: PTT.br is responsible to provide enough capacity to sustain bandwidth demand
on connection between PIX: (e.g. 1GE, 10GE, nx 10GE with DWDM).
PIX - Interconnection Point
Each entity that hosts a PTT.br PIX is responsible to provide continuous and high quality:
● IDC Infrastructure
Rack Space, Electrical Energy, Refrigeration, Physical Security,
Operational Hand, etc
● Dark Fiber Pair (preferably redundant) to Central PIX

Multi-Lateral Peering Agreements (MLPA)
IP (v4/v6) traffic exchange between all participants.
BGP sessions established between participants and IXP route servers.
Different MLPA VLANs for IPv4 and IPv6.
Bilateral Peering Agreements (BPA)
Shared VLAN Mode
IP traffic exchange only between participants.
Use the same MLPA VLANs.
Dedicated VLAN Mode
IP traffic exchange only between participants (e.g. Internet Transit).
Use a dedicate VLAN for each peering agreement.
