Abstract
A method of determining which of plural protocols are active on a computerized local area network. Each of plural frame types are registered with a link support layer (LSL) which monitors network communications for broadcast frame packets. A frame packet which matches a first one of the frame types is provided from LSL, and protocol header information in the received frame packet is decoded so as to determine protocol used in the frame packet. The first frame type is de-registered from LSL, a first protocol stack corresponding to the determined protocol is initialized using the first frame type, the first protocol stack is loaded, and the first protocol stack registers itself with LSL so that the first protocol stack receives future frame packets which match the first frame type. Thereafter, if LSL encounters any other frame types, the above processing is repeated so as to load and register any other needed protocol stacks.
