{{distinguish|Network Description Language}}
'''NDL''' ('''Network Definition Language''') was a compiler on Burroughs Large and Medium Systems computers used to create a network definition file for a data communications controller (DCC) and object code for a data communications processor (DCP) that interfaced between a message control program (written in DCALGOL) such as (RJE), (MCSII) or (CANDE) and the computer's line adaptors and terminal network.<ref>Burroughs B6700/B7700 System software handbook (form no 5000722)</ref><ref>Burroughs Network Definition Language (form no 7000078)</ref>
Burroughs Network Definition Language allowed many parameters of the mainframe communications adapter, modems (where used), protocol and attached terminal to be defined. However it treated the low-level operation of the multi-drop protocol, including the modulus of sequence numbers and the algorithm used for CRCs etc. as primitives.
