摘要： In a computer implemented method an address book is dynamically generated in a distributed mail service system. The distributed mail service system includes a plurality of client computers connected to a mail service system via a network. Mail messages are stored in message files of the mail service system. Each mail message is parsed and indexed to generate a full-text index of the mail service system. An address book mail message is generated, each address book mail message including address information. The address book mail messages are stored in the message files, and parsed and indexed into the full-text index file. A query is composed using a particular one of the plurality of client computer systems to search the full-text index to locate and retrieve selected ones of the address book mail messages as the dynamic address book.

摘要： In a computerized method for labeling data records, data records are received in an index server. The records are parsed into words, and the words are stored in a full-text index. Labels are added to the data records and the full-text index. The data records are accessed by searching the full-text index using queries including the words and the labels of the data records. Labels can be removed from the full-text index.

摘要： A computer implemented method for filtering mail messages in a distributed computer system. The distributed mail service system includes a plurality of client computers connected to a mail service system via a network. Mail messages are stored in message files of the mail service system. Each mail message is parsed and indexed to generate a full-text index of the mail service system. A query is composed, the query includes terms and operators. The query is stored in the mail service system as a named filter query. A new mail message received by the mail service system is parsed, indexed and searched to determine if the content of the new mail message does not match on the named filter query, in which case an inbox label and an unread label to the new mail message.

摘要： A computer implemented method for down-loading mail messages in a distributed computer system. The distributed mail service system includes a plurality of client computers connected to a mail service system via a network. Mail messages are stored in message files of the mail service system, a particular mail message includes a primary component encoded in a first format, and at least one secondary component encoded in a second format different than the first component. The particular mail message is requested by a particular one of the plurality of client computer systems. The secondary component is replaced with a hot-link. The primary component and the hot-link are sent to the particular client computer.

摘要： In a computer implemented method, a client computer connected to a public network such as the Internet makes a request for an intranet resource to a tunnel of a firewall isolating the intranet from the Internet. The request is made in a public message. The tunnel sends a message to the client computer to redirect to a proxy server of the tunnel. The client computer send a token and the request for the resource the proxy server. If the token is valid, the request is forwarded to the intranet, otherwise, the user of the client computer must first be authenticated.

摘要： A distributed computer system includes a multiplicity of concurrently active processes. Each object is owned by one process. Objects are accessible to processes other than the object's owner. Each process, when it receives a handle to an object owned by any other process, sends a first "dirty" message to the object's owner indicating that the object is in use. When a process permanently ceases use of an object handle, it sends a second "clean" message to the object's owner indicating that the object is no longer in use. Each object's owner receives the first and second messages concerning usage of that object, stores data for keeping track of which other processes have a handle to that object and sends acknowledgement messages in return. The receiver of an object handle does not use the handle until its first message is acknowledged. Periodically, the object's owner sends status request messages to other processes with outstanding handles to that object to determine if any of those processes have terminated and updates its stored object usage data accordingly. A garbage collection process collects objects for which the usage data indicates that no process has a handle. The first and second messages include sequence numbers, wherein the sequence numbers sent by any process change in value monotonically in accordance with when the message is sent. Object owners ignore any message whose sequence number indicates that it was sent earlier than another message for the same object that previously received from the same process.

摘要： A mesh connected local area network provides automatic packet switching and routing between host computers coupled to the network. The network has a multiplicity of cut-through, nonblocking switches, each capable of simultaneously routing a multiplicity of data packets. Low host-to-host latency is achieved through the use of cut-through switches with separate internal buffers for each packet being routed. The switches are interconnected with one another and are coupled to the host computers of the network by point to point full duplex links. While each switch can be coupled to ten or more network members, i.e., switches and hosts, each link is coupled to only two network members and is dedicated to carrying signals therebetween. Whenever a new switch or link is added to the network, and whenever a switch or link fails, the switches in the network automatically reconfigure the network by recomputing the set of legal paths through the network.

摘要： Methods and systems are provided for a cancellation server maintaining a database of identifiers of cryptographic puzzles. A cryptographic puzzle is created from a unique identifier and a timestamp, and is attached to an electronic mail message, along with the puzzle's solution. The recipient verifies that the solution is correct and that the timestamp is current, and further queries the cancellation server with the puzzle identifier. If the identifier does not exist in the database, then the recipient knows the received message is legitimate. If the identifier already appears in the database, the received message can be automatically removed from the recipient's computer.
