Internet Protocols for Networked Virtual Environments

Common Internet Protocols

• Internet Protocol

  • End to End connectivity between source and destination hosts(s) across heterogeneous transmission media, including fragmentation and Time to Live (TTL) services

• TCP

  • Point-to-point connection with reliable transmission using acknowledgement and retransmission, providing stream-based data semantics.

• UDP

  • Lightweight data transmission with "best efforts" delivery (e.g. no reliability guarantees), providing packet-based data semantics.

• Broadcasting

  • "Best effort data transmission to all hosts on a LAN. Appropriate for small LANs and low-bandwidth transmissions

• Multicasting

  • Efficient, "best efforts" data transmission to multiple destination hosts whose individual identities are anonymous to the transmitter. Appropriate for the Internet and large scale systems.
