Abstract
An option request protocol allows dynamic negotiation of options between a host computer and a control unit of a computer network. The protocol is manifested as an exchange of novel control messages over a control link used to establish logical data links for communication between the host and control unit. The options negotiated by the control message exchange generally pertain to additional functions performed by the control unit or host, or additional parameters for communication over the data links coupling the control unit and host.
