QLLC: Qualified Logical Link Control
Qualified Logical Link Control (QLLC) is an IBM-defined data-link layer protocol that allows SNA data to be transported across X.25 networks. When SNA is used over X.25, it uses the qualifier-bit (Q-bit) in the X.25 packet header to indicate special link control information. This information is relevant for SNA control between the two systems communicating with each other but is of no concern to X.25 link control.
