The version field in a PDU (Protocol Data Unit) is typically encoded as a single byte. This byte specifies the version of the protocol being used for the communication. For example, in the Simple Network Management Protocol (SNMP), the version field is encoded as a single byte with the value 0×00 representing version 1, 0×01 representing version 2c, and 0×02 representing version 3. Other protocols may use different values or encoding schemes for the version field, but it is typically a small, fixed-size field that is easy to parse and interpret.
