The Internet Link protocol or (IL) is a connection-based transport layer protocol designed at Bell Labs originally as part of the Plan 9 operating system and is used to carry 9P. It is assigned the Internet Protocol number of 40. It is similar to TCP but much simpler.
Its main features are:
- Reliable datagram service
- In-sequence delivery
- Internetworking using IP
- Low complexity, high performance
- Adaptive timeouts
