Interface and Protocol Expertise

This chart reflects many interfaces and protocols that TELE-WORX consults on. This chart is not intended to be exhaustive; only the primary protocol acronyms are indicated above. Further, several protocols in this chart reflect encyclopedic collections of functions that may span multiple layers. The chart above, therefore, is intended to be illustrative and not necessarily definitive.

Assignment of a protocol stack to a particular transport technology that is supported by a particular network management application is not as rigorous as this chart may suggest. For example, there are many instances of SONET network equipment managed with TL1 or SNMP through a TCP/IP stack.

SIDEBAR

Assignment of a protocol to a layer is generally made according to its functionality when no formal assignment has been documented by a standards body or industry forum. Reference to contemporary writing about interfaces and protocols exposes significant disagreements even among the experts about layer assignment. In the case of Ethernet, the philosophy of the designers was not entirely consistent with the OSI reference model of layers and layer functionality, and several protocols in the Ethernet suite spill into the adjacent layer of OSI functions.
