摘要： Cross-service connectivity between use of the telephone network and use of an e-mail data network is provided by enabling a recipient of an e-mail message to receive e-mail messages through an alias e-mail address which is directly associated with the recipient's telephone number. Thus, the alias e-mail address consists of the recipient's telephone number as the recipient name at a well-known and publicized common domain name server. A sender therefore addresses an e-mail message to the recipient to that alias e-mail address using the recipient's alias telephone number name. A message addressed to the alias e-mail address is sent to a translation server at that known domain name, where the alias telephone number-recipient name is translated to the actual e-mail address comprising the recipient's actual name and associated domain name server, and the message is then forwarded to that recipient at that actual e-mail address. Such aliasing capabilities are effected through a registration process in which the recipient registers for such a service and provides to the translation server his or her actual e-mail address and associated telephone number to which senders of messages to that recipient can use to address e-mail messages.

摘要： A mobility support technique provides home agents and foreign agents in mobility aware access networks. Participating mobile hosts are assigned a home address that is used by other hosts as the mobile host's address. The home address actually addresses the home agent provided in the mobility aware access network. The home address provides additional privacy to the mobile host because it does not identify the mobile host's home premises network where the mobile host resides permanently absent any mobility of the mobile host. By providing home agents and foreign agents in a mobility aware access network, the agents may cooperatively establish optimal routing paths for data transmitted to a mobile host. The agents may identify a pseudo home agent, an agent in a mobility aware access network located near to a transmitting mobile host, that acts as the home agent of a destination mobile host. The pseudo home agent tunnels data directly to the destination mobile host without requiring the data to be routed first to the true home agent. In this regard, the pseudo home agent establishes a more direct routing path between the transmitting and destination mobile hosts.

摘要： Unicast endpoint clients on an IP Unicast network are provided access to Multicast sessions on an IP Multicast network through a Multicast-Unicast gateway server. The server obtains information about sessions on the Multicast network and makes such information available to a Unicast client on the Unicast network upon request by the client. Upon being presented with a list describing the subject matter of each session, the user at the Unicast client selects the session to which he or she wants to join, which causes the Multicast-Unicast server to join the appropriate session on behalf of the requesting client. All packets then received by the server from the Unicast client are address-translated to the appropriate Multicast session address and vice versa. The Unicast client is then able to participate in the Multicast session as both a sender and receiver of packets to and from other Unicast and Multicast clients which are active.

摘要： Proposed is a system and method for providing Intelligent Network services. In one embodiment, the system of the present invention includes a database interacting with a socket redirector installed on a client computer. In one method implemented using the system of the present invention, a socket redirector intercepts a standard Internet Protocol (IP) socket call from a client software application and identifies parameters within the socket call. If the redirector is able to determine that the identified parameters are addressed to the most appropriate socket for accommodating the software application's request, the IP socket call is sent to network software where the socket call is used to form packets which are sent over the network to the requested socket. If the redirector is unable to determine that the identified parameters are addressed to the most appropriate socket for accommodating the request, the redirector requests instructions from a database. The socket redirector then modifies the IP socket call parameters using the instructions received from the database and sends the modified IP socket calls to network software for processing as described above.

摘要： A system and method are disclosed for the repair of IP multicast sessions. A repair server polls multiple transmit servers to accumulate as many of the packets missing from the multicast session as possible. A network includes a source of multicast packets in a multicast session and a plurality of multicast recipients in that session. A repair server in the network provides the packets it receives to the recipients. The repair server includes a missing packet detector. There is a plurality of retransmit servers in the network buffering portions of the packets they respectively receive during the session. The repair server maintains an ordered list of the retransmit servers that are most likely to have buffered copies of packets missing from the session. When the repair server detects that there are packets missing from the session it has received, it uses the ordered list to sequentially request the missing packets from respective ones of the plurality of retransmit servers.

摘要： In a multicast capable IP network implemented over an ATM network, each client terminal on a multimedia conference, for each media type it transmits, is assigned a multicast IP address and a port number (together known as a socket) on which to transmit packets, wherein each assigned multicast IP address is unique and different than the multicast IP address assigned to any other client for any media type. Each client terminal then selects, for each media type, which clients on the conference it wants to receive packets from. Only packets that are in fact requested by a client are routed over the multicast IP network to the requesting client. A single special purpose Multicast Address Resolution System (MARS) server is associated with the conference when the conference is established. Each client terminal uses that MARS server, whether on the same or different IP sub-networks, but on a common ATM network, for purposes of mapping the multicast IP addresses used in the conference into a set of unicast ATM endpoint addresses used by the ATM-connected client terminals. Similarly, when a specific conference uses a Multicast Server, a single special purpose Multicast Server is used for all clients on the conference, whether on the same or different IP sub-networks, for purposes of establishing point-to-multipoint ATM connections to the conference endpoints.

Each client terminal then selects, for each media type, which clients on the conference it wants to receive packets from. Only packets that are in fact requested by a client are routed over the multicast IP network to the requesting client. When a conference originator establishes the conference, a number of multicast IP addresses are allocated for later assignment to the clients during the conference. As each client joins the conference, it is assigned a multicast IP address from the allocated group for each media type it will transmit. Those assigned addresses are then marked as unavailable for assignment to any other client that subsequently joins the conference. When the original client later exits the conference, its assigned multicast IP address(es) is (are) marked as available for assignment to a later joining client. At the conclusion of the conference, all multicast IP addresses allocated to the conference are marked as available for use in another conference.

摘要： A endpoint client (111-1) on an IP Unicast network (107) that is provided access to a Multicast session on an IP Multicast network (101) through a Multicast-Unicast gateway server (MUS) (120) is enabled to re-Multicast that session to other endpoint clients (111-2) on the network to which it is connected or to endpoint clients (134, 135) on any Multicast-capable sub-network (132) to which it is directly connected. To act as a re-Multicaster, the endpoint client receiving Unicast-addressed packets from the session from the MUS, re-translates these Unicast-addressed packets to Multicast-addressed packets by translating the Unicast address in the distribution field of each packet's header into a Multicast address and overwriting the Unicast address in each header with the Multicast address. When an endpoint client on the same or connected sub-network as the re-Multicaster desires to join a session that is being re-Multicast, it needs only connect to that Multicast address. A endpoint client on a Unicast network can elect to be a re-Multicaster of packets from a session as long as that same session is not being re-Multicast by another endpoint client on any sub-network on which the electing re-Multicaster is connected or a Multicast router is not forwarding packets from the session onto the sub-network.
