WebFrame Format. An FDDI frame is very similar to that defined by the traditional token ring, but there are only eight fields. The Token and frame format for the FDDI shown in Figure (a) and (b), respectively. The Control token structure is very much similar to the Token ring case. Eight fields make up the FDDI frame. They are: WebData (and Padding) The Data field carries the user data or NCP packets. This field is sometimes called the Payload field. FCS The Frame Check Sequence field uses the same format as it does in HDLC. It contains a 2- to 4-byte cyclic redundancy check (CRC).
