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 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： 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： In order to reduce the delay and/or loss of packets caused by the transmission through a large number of routers on the Internet, a direct connection is established between a client (or its proxy) and a server if the client (or its proxy) and the server are connected to the same alternative subnetwork. Control management information, including the type of subnetwork to which each is connected, as well as the address of the client (or its proxy) and the server are transmitted to the other on the Internet in an optional HTTP header field. After receipt of the addressing information, a direct connection is established on the alternative subnetwork between the client (or its proxy) and the server for purposes of streaming information from the server to the client.

摘要： On the Internet, different caches may contain copies of objects that have been copied from originating servers when they were accessed by users. Interconnected caches may have different objects stored thereon that might at some time be requested by a client terminal that is connected to a cache other than the one on which the object is stored. Rather than awaiting a request for a particular object and then querying each neighbor cache to determine whether a copy of the requested object is stored thereon, and then downloading the requested object if it is found, information about the contents of the neighbor caches is exchanged between these caches so that when a request for an object is received, the object can be retrieved from the cache in which it is stored. In the alternative, the object may be retrieved from the originating server if, for example, the object stored in a cache is stale based on the date and time it was last modified in the cache.

摘要： A method includes receiving, at a transmit site, a first stream of packets addressed to an end user device in a first address space. The first stream of packets is encapsulated to form a second stream of packets addressed in a second address space. A first packet of the second stream of packets is assigned to a first radio frequency channel of a plurality of radio frequency channels. A second packet of the second stream of packets is assigned to a second radio frequency channel of the plurality of radio frequency channels. The first packet is transmitted via the first radio frequency channel and, in parallel, the second packet is transmitted via the second radio frequency channel.

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： A method and apparatus that enhances a multicast information stream, such as an IP multicast session, in a communication network is provided. The stream is received through the communication network and is enhanced at substantially the time the first stream is received. The information stream may be enhanced by adding transcribed content, such as content generated by speech recognition software, or translated content, such as from a first language to a second language, to the stream. The information stream may also be enhanced by adding content to the first information stream, such as content is related to the original content. The enhanced stream may be sent to a user as a second multicast information stream. The enhanced stream may be received by the user in place of, or along with, the original information stream. The enhanced content may be sent to the user at the conclusion of the information stream, if desired.
