Abstract:
1. A system for transmitting digital information from a first network element to a second network element in an Ethernet frame switched data network, the system including: in said first network element a writing unit that defines which bits of a frame data field of a minimum sized Ethernet frame correspond to padding bits in a frame data field of said minimum sized Ethernet frame on the basis of a type of an information unit placed in said frame data field and on the basis of a predetermined rule and to write said digital information into a first portion of the padding bits, and in said second network element a reading unit that reads said digital information from said padding bits, wherein said writing unit writes flag data into a second portion of the padding bits of said frame data field of said minimum sized Ethernet frame, said flag data indicates whether said first portion of the padding bits represent said digital information.
