JXTA

• Collection of open peer-to-peer protocolsAny
  connected device can participate in P2P
  networkOperating system- and language-independent
  Basic services and infrastructure for
  communication in NAT and firewall constrained
  network
• Virtual groupsCollections of peers providing
  equivalent servicesMembership authentication
• Pipes virtual connections between
  peersJxtaSockets implementation of familiar
  socket API over P2P Can use JXTA discovery
  features via XML-based advertisements

H2O over JXTA
List of currently registered kernels

• Resource sharing on the P2P networkH2O uses JXTA
  via the JXTA-enabled RMIX
• Dynamic kernel groupsAd-hoc collaborations with
  custom authentication services
• JXTA enabled Name ServiceAutomatic discovery of
  JXTA-enabled kernelsInformation propagated over
  the JXTA network
• Network delay monitoringName Services monitor
  delay times for each kernelsPluglet deployment
  decisions can be made on the basis of observed
  delays
