ABSTRACT:
Token Ring network packet having a header and an information field is prepared for transmission over an Ethernet network by the steps of removing the header information from the Token Ring packet, and associating a second header with the information field of the Token Ring packet, wherein the second header is compatible with the Ethernet network. More particularly, to prepare an IEEE 802.5 Token Ring network packet for transmission on an Ethernet network the Access Control ("AC") and Frame Control ("FC") fields are removed, the order of the destination address ("DA") field is reversed, the order of the source address ("SA") field is reversed, a Virtual Local Area Network ("VLAN") type field is added, a VLAN identification ("ID") field is added, and a length value field is added. The information field from the Token Ring packet is retained. However, if the newly formed tunneled packet would otherwise be smaller than the minimum size for an Ethernet packet the information field may be padded with null bits until the minimum size for an Ethernet packet is achieved.
