History of Wunet

Wunet Concepts

  • Virtual Node
    • Vaddr (Virtual address)
  • Vnet (Virtual Network)
    • Vlink (Virtual Link)
  • Subscribe/Unsubscribe

Wunet Features

  • UDP Encapsulation:
    • Each packet is encapsulated in UDP packet
  • Virtual Addresses:
    • There are unicast addresses(e.g., 21, 200) and
    • Multicast addresses(e.g., 2200110011 = x832303BB) addresses.
      • Any address with high-order bit set is mcast addr; i.e., any decimal number greater than 2^31-1 = 2,147,483,647.
  • Packet Types: DATA, SUBSCRIBE, UNSUBSCRIBE
  • Routing:
    • Packets are routed by (vnet, vaddr)
  • Route Learning:
    • A router will add a reverse route for any incoming packet with a source address not found in the routing table
  • Joining/Leaving Multicast Group:
    • A host joins/leaves a multicast group using SUBSCRIBE/UNSUBSCRIBE
  • Multicast tree is formed for each vnet through SUBSCRIBE packets that travel up the multicast tree
  • Missing Routes:
    • Unicast Data: Flood all downstream links when there is no route.
    • Multicast Data: Send subscriptions upstream when there is no route.
