HOPI Hybrid OpticalPacket Infrastructure
The Hybrid Optical and Packet Infrastructure
(HOPI) project is examining a hybrid of packet
and circuit switched infrastructures and how to
combine them into a coherent and scalable
architecture for next generation networks.

HOPI Control Plane
What is the Control Plane? The Control Plane
is the set of routing and provisioning protocols
that enable the network to dynamically select and
allocate dedicated resources along a specific
path to meet a users service requirements.

• HOPI has deployed Generalized Multi-Protocol
  Label Swapping (GMPLS) protocols that establish
  Ethernet VLANs across the HOPI backbone
• DRAGON Virtual Label Swapping Router (VLSR) for
  intra-domain provisioning
• GMPLS-OSPF-TE routing and path computation
• GMPLS-RSVP-TE for signaling and light path
  provisioning
• DRAGON Network Aware Resource Broker (NARB) for
  inter-domain
• Listens to IGP for LSAs
• Resource advertisement with topology reduction
  across domains
• Performs inter-domain Path Computation
• AAA and book-ahead scheduling via the
  3d-Traffic Engineering Database

• All control plane software is Open Source and
  freely available to encourage adoption,
  evolution, and maturation

e-VLBI Connecting the Worlds Radio Telescopes
via High-Speed Networks
Correlator

• Very-Long Baseline Interferometry (VLBI) is a
  radio-astronomy technique that uses an array of
  highly coordinated radio telescopes, scattered
  across the globe, to create the equivalent of a
  single large coherent antenna.
• Continuous data rates up to 1-Gbps/telescope are
  now being collected, with demand for increased
  rates in the future. Traditionally, data are
  recorded on magnetic tape or disks and shipped to
  a central correlation facility for processing.
• e-VLBI transmits data from telescope to
  correlator using global high-speed networks data
  may be transmitted either in real-time or
  near-real-time, depending on available network
  facilities.
• For astronomy VLBI provides the highest
  resolution images of any technique available
  images equivalent to the dimples on a golf ball
  at a distance of 3000 miles can be made!
• For geodesy VLBI provides ultra-high-precision
  measurements of the Earth and its motions in
  space the 3-dimensional distances between
  antennas can be measured to a few-mm over the
  entire globe! In addition, the positions of
  radio sources can be measured to about 1
  milliarcsecond!
