Abstract
Abstract An improved method and apparatus are provided for queuing and triggering the flow of data across ATM networks. A connection is established between an insertion server and a client multiplexer. The insertion server prepares a timing response and establishes a transmit queue threshold for a pending trigger point for inserting data. The insertion server enqueues data. Responsive to receiving a timing request from the client multiplexer, the insertion server sends the timing response. Responsive to receiving a stream request from the client multiplexer, the insertion server transfers the enqueued data. The client multiplexer includes a timer for identifying an offset time between sending the timing request and receiving a timing response from the insertion server. The client multiplexer uses the offset time to set a count down timer for sending the stream request. The client multiplexer processes the data transferred by the insertion server and optionally sends a stop stream command to the insertion server.
