The networking protocol module is responsible for implementing the details of a particular protocol (e.g., Qnet).
Each protocol component is packaged as a shared object (e.g., lsm-qnet.so). One or more protocol components may run concurrently.
For example, the following line from a buildfile shows io-pkt-v4 loading the Qnet protocol via its -p protocol command-line option:
io-pkt-v4 -dne2000 -pqnet
Qnet is the QNX Neutrino native networking protocol. Its main purpose is to extend the OS's powerful message-passing IPC transparently over a network of microkernels.
Qnet also provides Quality of Service policies to help ensure reliable network transactions.
