Abstract

An apparatus for calculating a cost of receiving multicast data from a multicast session. A multicast network includes at least one multicast service, each multicast service including at least one multicast session. The apparatus receives a request to establish a connection to the multicast session, stores a start time for the connection and an end time for the connection and, after termination of the connection, calculates the cost of receiving the multicast data The apparatus can receive a subsequent request to extend the connection, the subsequent request specifying a new end time for the connection, and store the new end time for the connection. Alternatively, the apparatus can receive a subsequent request to terminate the connection, the subsequent request specifying a new end time that precedes the end time for the connection, and store the new end time for the connection.
