ESnet

• The Energy Sciences Network (ESnet)
• A very high bandwidth ATM network funded by the
  Dept. of Energy for support of its energy
  research programs
• ESnet peers with other commercial research
  networks at the major interconnection points in
  the country
• ESnet supports (some) international links that
  have energy research support aspects.
• ESnet acts as FNALs Internet service provider
• All of the Laboratorys traffic to the commercial
  Internet goes via Esnet
• Few FNAL Collaborators are on the ESnet backbone
  ESnet is our transit network to their Internet
  provider.
• Performance across ESnet tends to be excellent
• Once your data gets off of ESnet, performance may
  degrade...

MREN

• The Metropolitan Research Education Network is
  a Chicago-based advanced research network
• MREN co-resides with the Chicago Network Access
  Point (NAP), a major commercial internet
  connection point
• MREN is an Internet-2 GigaPOP, with high
  bandwidth connections to Internet-2 backbone
  networks.
• FNAL has an OC3 (155Mbps) MREN link
• Used to establish direct network connections with
  other MREN members
• Provides FNAL with an OC3 (155Mbps) connection to
  the Internet-2 network(s).
• Performance is very good current utilization is
  low.

Internet-2

• A consortium to form research network(s) that
  advance development of the next generation
  internet
• One objective is a high performance network for
  general research (ie., the pre-commercialized
  internet).
• Another is to advance internet technology itself
• No commodity internet traffic!
• Univ A lt--gt Univ B via vBNS (Internet-2)
• Univ A non-Internet-2 via commercial ISP
• Universities need 2 Internet connections
• The vBNS is the initial Internet-2 network
• The Abilene network is just coming into
  existence it may replace (or more likely
  augment) the vBNS.

International Connections

• Level of connectivity general performance vary
  by the specific international trans-oceanic
  connection
• ESnet peers with some national networks directly
• CERN, FRG/WIN at Perryman, Maryland
• INFN at Princeton.
• Other national networks use commercial Internet
  service providers.
• STARTAP
• An international connection exchange, located at
  Chicago NAP
• Japan-HEP now connected there CERN will
  reconnect there
• Potentially means optimal connectivity to FNAL
  offers the possibility of early network exotica
  deployment (QOS).
