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： 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： 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： On the Internet (106), rather than retrieving a frequently requested Web object from its originating server (105) in response to a request from a client terminal (101, 102), the object rather can be retrieved from a cache (103) within the Internet Access Service Provider (IASP) (104), which connects the client terminal to the Internet. What is stored in the cache may, however, not be the most recent version of the object. Distinct from providing the Web object itself, information about changes to the object is provided by the server in response to a cache request that is asynchronous to a request from a client for the object. Such information about changes to an object includes the date and time when the object was last modified, the byte size of the modified object, and information on the type of content of the object. After receiving this information about changes to an object, the cache may then request that a copy of the object be downloaded to it.

摘要： We have realized that for a connection over a large data network, such as an Internet connection that couples a web access device to a terminal server connected to an applications server, delays associated with the process of downloading large data files over such a connection, occur primarily in the leg of the connection that couples the applications server to a terminal server while little congestion is typically observed in the leg of the connection that couples the Internet access device to the terminal server. The aforementioned delay is reduced by establishing a separate connection from the applications server to the Point Of Presence server outside or independently of the backbone of the large data network thereby allowing users to receive enhanced grade of service for file transfer operations.
摘要翻译：我们已经意识到，对于通过将网络访问设备耦合到连接到应用服务器的终端服务器的大型数据网络的连接，发生与通过这样的连接下载大数据文件的过程相关的延迟主要是在将应用服务器耦合到终端服务器的连接中，通常在将因特网接入设备耦合到终端服务器的连接中通常观察到拥塞很少。通过在大数据网络的骨干网之外建立与应用服务器到存在点服务点的单独连接，可以减少上述延迟，从而允许用户接收文件传输操作的增强等级的服务。

摘要： A system and method for providing anonymous voice communications using the telephone network under the direction of an on-line data network. A call broker receives call setup information from on-line session participants, such as chat room participants, after providing callback telephone numbers and, as appropriate, billing information. In one illustrative embodiment, a user (the call initiator) present in a chat room session establishes a data connection to a telephone company site using, e.g., an Internet web browser to establish a Call Broker session. The Call Broker then provides session information (such as a telephone company URL) and a Participant Authorization Code (PAC), which information is passed to a selected chat participant in the current chat room. When the chosen participant uses the received URL to access the telephone company site, and enters the received participant code and a call-back number, the telephone company completes voice links to the initiator and the selected participant and bridges these links together. Other embodiments permit adding additional parties, and engaging the chat server to negotiates with the Call Broker to establish a PAC that is made available to all chat participants. These and other embodiments of the present invention permit participants in an on-line chat or similar text-based session to retain their anonymity while extending their communications to voice calls.

摘要： A caching scheme for spatially distributed databases in which a central database maintains all information to be stored. A plurality of local databases include copies of the information stored in the central database. For each data record in the central database, there is at most one copy of the data record in the set of local databases.The caching scheme includes a method for serving database requests in which a service request is made to a first local database located in the area from which the request originates. If the first local database fails to service the request, the central database services the request. After serving the request, a second local database that contains the data record is identified and the data record therein is destroyed. A new copy is written to the first local database.

摘要： A plurality of users communicate in a plurality of real-time text conversations (e.g., “chat sessions”) in a client-server message processing environment using messages including a conversation index, a conversation-initiator ID and a list of message recipients. Each conversation is maintained at client terminals in an individual window. Dropping and controlled adding of conversation participants is attended by message updates to other participants. Alternative peer-to-peer message handling reduces the processing burden on servers while allowing clients to perform control and display functions. Voice or other non-text messages are also communicated using described techniques.
