Abstract: A packet repeater is connected between an IEEE-1394 host terminal and a PPP server. The host terminal transmits a PPP packet containing the physical address of an IEEE-1394 device. During a discovery stage of a PPP connection, the packet repeater receives a PPP packet from the terminal, copies the physical address contained in the packet to an entry of a management table, and successively receives packets from the server and copies the physical address of the server and a session identifier respectively contained in the packets to that entry of the table. During a session stage of the connection, the packet repeater receives a PPP packet either from the terminal or the server and determines the destination of the packet according to the physical address of one of the terminal and the server which is set in the table corresponding to a session identifier of the packet.

Abstract: A handle administration system is described in which software agents receive handles to various resources that they can use to obtain the resources. The described embodiments provide multiple states that can be assumed by the handles. An unassigned state is provided in which handles are not assigned to a particular resource, nor can they be dereferenced to obtain pointers to any resources. An assigned state is provided in which handles are assigned to a particular resource and can be dereferenced to obtain a pointer to the resource. A suspended state is provided in which the handles are assigned to a particular resource but cannot be dereferenced to obtain a pointer to that resource. Advantageously, a suspended handle can be reinstated to assume the assigned state. In one embodiment, the handle system is implemented by incorporating a suitable field in a handle database that is used to indicate that a handle is suspended. In another embodiment, no additional fields are necessary.

Abstract: A method of communicating frames of management information includes loading a frame of management information from one of a plurality of stations into a respective one of a plurality of buffers. Whether the frame contains more than a predetermined number of bytes is determined. If an end of the frame is loaded into the respective one of the buffers, then a frame presence flag associated with said one of the plurality of stations is set. A request signal is transmitted to a station management module if the frame contains more than the predetermined number of bytes or if the buffer already contains management information associated with a previously loaded frame. The plurality of stations is polled to determine whether respective frame presence flags have been set.

Abstract: In order to prevent unnecessary APIPA process from being executed in a LAN environment which does not adopt APIPA, an ICMP echo request for a predetermined IP address is broadcast. Whether there are more than N apparatuses using APIPA is checked based on the replies, and if there are, IP address setting by APIPA is executed. In a LAN environment which adopts APIPA, whether the IP address to be assigned to an apparatus is already being used by another apparatus is checked. If the date and time when the another apparatus was assigned the IP address is earlier than the date and time when the apparatus was assigned the IP address, APIPA is executed to decide the IP address of the apparatus.

Abstract: A secure streaming content delivery system provides a plurality of content servers connected to a network that host customer content that can be cached and/or stored, e.g., images, video, text, and/or software. The content servers respond to requests for customer content from users. The invention load balances user requests for cached customer content to the appropriate content server. A user makes a request to a customer's server/authorization server for delivery of the customer's content. The authorization server checks if the user is authorized to view the requested content. If the user is authorized, then the authorization server generates a hash value and embeds it into the URL which is passed to the user. A content server receives a URL request from the user for customer content cached on the content server. The request is verified by the content server.

Abstract: Automated techniques are described that provide continuous, uninterrupted operation of the secure packet tunnels in spite of access link flooding attacks. A system is described that includes a source device and a destination device coupled to a network. The source and destination devices may comprise, for example, edge routers that couple local area networks to the network via access links. The source device and the destination device establish a packet tunnel that has a source network address and a destination network address. Upon detecting a network attack, the destination device selects a new network address for at least one of the source network address and the destination network address and establishes a new packet tunnel with the source device. The source network address and the destination network address may comprise port numbers, Internet Protocol (IP) addresses, or other information describing the source and destination devices.

Abstract: A method, system, and program for selective mirrored site access from a communication are provided. When composing a communication, multiple mirrored site addresses are embedded with a target site address. The sender may request to enter the mirrored site addresses or a browser supplies the mirrored site addresses. At each client system receiving the communication, selections of site addresses accessible for each intended recipient are detected. Thus, each client system, when outputting the communication, displays the selection of mirrored site address accessible to the intended recipient accessing that client system.

Abstract: A method that allows the normalization of traffic data that is simultaneously transferred to a network intrusion detection system (NIDS) and monitored end-systems located in a network, such as a TCP/IP network, in which packets of data such as IP datagrams, are fragmented and reassembled. Accordingly, the information of received fragments and/or the topology of the network comprising the network intrusion detection system (NIDS) and the monitored end-systems are entered into a normalization table, that is dynamically established and maintained. Subsequently packets of data such as IP datagrams are modified, redirected or discarded in case that ambiguities are detected when comparing information contained in the normalization table with information contained in the headers of the received data packets.

Abstract: The invention enables one or more agents to gather information from at least one server on a network and automatically provide this information to an inbox on a server and then providing it to an inbox on a mobile device if a wireless connection to the mobile device is available. A server agent facility provides for preprocessing requests for information from the mobile device, including, collecting the information out of band, filtering the collected information, and packaging the information for delivery in a format suitable for the mobile device. A server agent within the server agent facility may actively collect the information based on a variety of factors, including but not limited to, time, event(s), user profile, mobile device profile, request(s), alert(s), and historical behavior.

Abstract: A method is disclosed for balancing a load of clients of a network across a plurality of communications providers. Connection data that includes information on attempts to connect to the network and whether each attempt was successful is collected. A time-independent demand curve for each of the communications providers representing a likelihood of successful connection as against client load is determined, based on the collected connection data. The load of clients is then apportioned across the communications providers based on the time-independent demand curve for each of the communications providers.

Abstract: A system is provided for peer-to-peer messaging. The system includes a first client machine which may transmit a sequence of messages related to a subject. The transmission of each message can be in the form of multicast delivery or reliable unicast delivery. At least one second client machine communicates with the first client machine. Each such second client machine may receive at least a portion of the sequence of messages transmitted in the multicast form of delivery from the first client machine, and determines if there is an interest in the subject of the sequence of messages. The second client machine may determine if any messages in the sequence have not been received if there is an interest, and can transmit a request for re-transmission to the first client machine. The request identifies any messages of the sequence that were not received so that such messages can be re-transmitted by the first client machine to the at least one second client machine in the form of reliable unicast delivery.
