2 CGI.br NIC.br - CEPTRO.br 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. 2

10 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) 10

14 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) 14

18 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

19 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 19

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. 24
