History • Mexican LD markets opens in 1996 • New carriers were created and new networks were built • New networks included cross-border fiber routes to U.S.A. • Infrastructure were deployed between carriers for voice interconnection (co-location) • All new infrastructure allow rapid Internet growth in México

  3. History • Carriers became the dominant ISPs • Peering were built using existing infrastructure • Interconnections using E3, STM-1 and STM-4 circuits • Terms and conditions negotiated between both operator involved • Most of the current peerings were deployed between 2000 and 2003 • As of today no NAP has been built for tier 2 providers

  4. Typical high level considerations • Link utilization must keep below 80% utilization • No transit provided • List of prefix exchanged on a regular basis as a normal operational procedure • Each operator decides how to filter incoming advertisements • Use of BGP communities to change local preference attribute and influence traffic balance when there are more than one peering circuit
