A method for connecting a first communication system with a third communications system, by passing through a second communications system, is disclosed. A first frame is received from the first communications system, where the first frame has a multicast address as a destination address. The multicast address requires the frame to be transmitted onto the second multicast address is translated into a functional address. The functional address is written into a second frame, and the second frame is transmitted onto the second communications system. A station receiving the second frame translates the functional address into a multicast address and writes the multicast address into the destination address field of a third frame, and transmits the third frame onto the third communications system.

A connection apparatus for connecting a first communication system with a second communication system and a third communication system. A first frame is received from the first communication system, where the first frame has a multicast address as a destination address, and where the destination address requires the first frame to be transmitted onto the second communication system. The multicast address is translated into a functional address, and the functional address is written into a second frame transmitted onto the second communication system. The second frame is received and is transmitted onto a third communication system, and the functional address is translated into a multicast address for the third communication system, and the multicast address is written into a destination field of the frame as it is transmitted onto the third communication system. The second communication system may be a token ring system based upon an IEEE 802. 5 standard, and the functional address may be written into a DSAP field and into a PROTOCOL TYPE field of an 802.

There is provided a method that includes (a) including in a dataset, data indicative of a time, (b) executing a hash function on the dataset to yield a hash value, and (c) employing the hash value as a password for a user to access a device. There is also provided a method that includes (a) including in a dataset, data indicative of a time, (b) executing a hash function on the dataset to yield a hash value, (c) determining that the hash value matches a password from a user, and (d) granting to the user, access to a device. There are also provided systems that perform the methods and storage devices that contain instructions for causing processors to perform the methods.
