    Abstract: A data transmission method quickly and reliably transfers data (e.g., a computer file) from a source to recipients. While the frames are being transmitted, negative acknowledgments from recipients are received by the source. These acknowledgments indicate which frames require retransmission. After all frames have been transmitted out, a retransmission is performed by the source for only those frames which the acknowledgments indicate require retransmission. Additional retransmissions can occur. This multi-pass data transfer technique requires only negative acknowledgements to be sent by the recipients. Features include the ability to set the transmission rate and to define multicast groups. Also, it is possible to determine the capacity of links of unknown capacity using a "multicast network probe" feature of the invention, and to determine the frame error rates of known-capacity links by utilizing the same feature. A "multicast ping" feature of the invention can be used to determine the connectivity between a source and members of a multicast group. "Speed groups" can be set up after determining link capacities, or if they are already known, whereby the recipients connected to the source by the fastest links receive all of the data while slower-link recipients receive only a portion of the data, on the first pass. The number of recipients which can receive the data from the source can be greatly increased by using a "negative acknowledgement collection" scheme whereby "replication points" (preferably routers) collect individual negative acknowledgements and forward them as a unit to the next level.

    Abstract: To make registration and confirmation of groups and confirmation of data transmission more scaleable, particularly for large groups, the size of a host list pruned in subsequent transmission. This host list management can be achieved by (a) creating a message that includes a list of one or more receivers;(b) sending the message over a network; (c) receiving over the network one or more replies from one or more of the receivers; (d) identifying each receiver for which one of the replies was received and establishing another message that includes the list with the identified receivers; (e) sending the message established in step (d) over the network; (f) creating a modified list by removing the identified receivers from the list; and (g) if there are one or more receivers on the modified list, repeating steps (c), (d), (e), (f), and (g) using the modified list as the list.

    Abstract: This invention relates to a system and method for managing a session during which data is sent to receivers, wherein retransmission of the data to the receivers can be automatically rescheduled if the receiver did not receive some or all of the data. An object of the invention is to send content to receivers that did not or could not receive data during a multicast data transmission session. In accordance with this and other objects of the invention, one aspect of the invention relates to a method of managing a session during which data is sent to receivers. A first message is sent over a network a message to a list comprising at least one receiver, the first message relating to receiving data during a first session. Replies are received over the network from the receivers on the list. Based on the replies received, each receiver on the list that will not be receiving data during the first session is identified. After the first session is complete, a second message is sent over the network to the receivers identified as not receiving data during the first session. The second message relates to receiving data during a second session. In this manner, receivers that did not receive data during the first session can automatically be invited to join a second session for receiving data when the first session is complete. Thus, the second session can serve as an automatic recovery session for those receivers that do not receive data during a regular data session.

    Abstract translation: 本发明涉及一种用于管理数据发送给接收机的会话的系统和方法，其中如果接收机没有接收到一些或全部数据，则可以自动重新调度数据到接收器的数据。 本发明的目的是在多播数据传输会话期间向不接收或不能接收数据的接收机发送内容。 根据本发明的这个和其它目的，本发明的一个方面涉及一种管理会话的方法，在该会话期间将数据发送到接收机。 通过网络将消息发送到包括至少一个接收器的列表的第一消息，所述第一消息涉及在第一会话期间接收数据。 从列表中的接收者通过网络接收回复。 根据接收到的答复，识别出在第一个会话期间将不会接收数据的列表上的每个接收者。 在第一个会话完成之后，第二个消息通过网络发送到在第一个会话期间被识别为不接收数据的接收者。 第二个消息涉及在第二个会话期间接收数据。 以这种方式，在第一次会话期间没有接收到数据的接收机可以自动被邀请加入第二个会话以在第一个会话完成时接收数据。 因此，第二会话可以用作在常规数据会话期间不接收数据的那些接收机的自动恢复会话。
