3 GRNET3 a Gigabit dark fiber network for Research & Education

4 GRNET3 country-wide dark fiber Basic characteristics 35 PoPs Fiber optic pair: 8410 Km MANs Athens+Thessaloniki DF local loops in 33 cities (to be delivered)

5 GRNET3 IP architecture GRNET3 continues to provide IP services: IP routers installed at major Greek cities IP routers connected with 2,5G PoS framed lambdas implemented via GRNET s DWDM equipment Clients aggregated to the local GRNET3 routers by using 1GbE framed lambdas implemented via GRNET s DWDM equipment For clients with high requirements (called Power Clients PC) and traffic overcoming 1Gbps, an IP aggregation architecture is implemented 10Gbps uplinks are aggregated to a major PoP using DWDM and then served at the IP layer 5

6 GRNET: a human network as well Members of the academic and research community Core network Task force Staff from GRNET HQ National and EU structural funds groups Development of GRNET3 action

7 GRNET NOC Collaborative development and management of the network Basic and advanced services Computing Storage Cloud Media

8 GR-IX (Greek Internet Exchange) Neutral Multi Gigabit Greek ISP interconnection Local traffic stays in Greece
