1. A method of inverse multiplexing digital data from a source node to a destination node over a connection consisting of a plurality of transmission links, said data containing a series of ATM data cells, comprising steps of:
- at a connection start-up, the source node sending to the destination node ATM sequence number cells informing the latter of a specific round robin order in which the series of ATM data cells are to be transmitted over the connection;
the destination node sending ATM sequence number cells whose receive ready field is set to indicate that the destination node is ready to receive ATM data cells in said specific round robin order from the plurality of transmission links; and
the source node sending each ATM data cell in said series of ATM data cells to the destination node in said specific round robin order.

Abstract
In ATM networks, digital data in ATM cells are sent to a destination node over more than one transmission link in round robin fashion. This is called inverse multiplexing. At connection start-up, the source node informs the destination node of the specific round robin fashion of the transmission links so that the ATM cells are reassembled in a proper sequential order.

9. A method of inverse multiplexing digital data from a node to another node over a connection consisting of a plurality of transmission links, said data containing a series of ATM data cells, comprising steps of:
-
whenever the connection is to be reconfigured, a first node of the two nodes sending to the other node ATM sequence number cells whose sequence number field is set to indicate a specific round robin order in which the series of ATM data cells are to be transmitted over the connection; the other node, in response to the first node, sending ATM sequence number cells whose receive ready field is set to indicate the other node is ready to receive ATM data cells in said specific round robin order from the plurality of transmission links; and the first node sending each ATM data cell in said series of ATM data cells to the other node in said specific round robin order. - View Dependent Claims (10, 11, 12)
