  • Patent number: 6073176
    Abstract: A stack group bidding protocol (SGBP) establishes systems as members of a stack group connected together through one or more networks. When an event, such as establishment of a point-to-point link, occurs on one of the systems, a bid request is sent to each stack group member. Each stack group member then bids for the event. The bid is based on dynamic bid weighting criteria that varies depending on the computation capacity of the member at the time the bid request is initiated. A multichassis multilink PPP (MLP) protocol utilizes the SGBP to conduct multilink PPP sessions for links that either originate or terminate on different physical systems. A L2F forwarding protocol is used in combination with multichassis MLP to forward the links from one system to another system and offers location transparency.

  • Patent number: 6065040
    Abstract: An apparatus and method retracts a mobile agent from a second execution environment back to a first execution environment, the retraction being performed by the first environment sending a retraction request, and the second execution environment establishing a connection to the first execution environment in response. The second execution environment searches for an agent under its control corresponding to an agent identity in the retraction request, and converts the corresponding agent, if located, to a bit sequence and returns the bit sequence to the first execution environment via the connection. Sending the bit sequence through the established connection safely alleviates firewall issues because a connection is established from the inside of the firewall to the outside.

  • Patent number: 6065060
    Abstract: A high speed modem is provided which targets the use of a selectable, desirable portion of the total available bandwidth of a channel for achieving a data rate which nevertheless far exceeds that of conventional voice-band modems. In a preferred embodiment, the invention is implemented in an Asymmetric Digital Subscriber Loop (ADSL), and the nominal data rate is achieved using an analog front end (AFE) with subband filtering which causes an upstream transceiver to use only a selected number of available sub-channels for downstream data transmission and allows slower sampling rate for the AFE. The data rate of the modem is increased in a multiplicative fashion through modular expansion of a bank of AFEs to increase the number of transmitted downstream sub-channels.

  • Patent number: 6055574
    Abstract: A method of providing a service, to a plurality of terminals on a communication network, through a server on the communication network includes the following steps: 1) coupling a correlator to the network which links a unique name for the server to multiple network addresses; 2) providing a set of multiple computers on the network, each of which performs the service and is assigned a different one of the multiple network addresses; and, 3) incorporating a network address selector on the network which directs any one of the terminals to a single one of the computers, when an operator of that one terminal generates a request for the service which includes the unique name of the server. Due to this method, the server has a virtual single network address which means that from the point of view of an operator of a terminal, the service is being provided by a single computer on the network that has a single network address that corresponds to the server's unique name.

  • Patent number: 6055578
    Abstract: Delay times are modified in an Ethernet network device having captured the media channel by increasing the interframe spacing (IFS) between data packets. The modified IFS interval, increased by adding a delay interval to the minimum interpacket gap (IPG) interval after a first user-selectable number of consecutive successful transmissions, enables other network stations to transmit data during the deferral interval. The Ethernet network device maintains the modified IFS for a limited deferral interval, based upon a predetermined time interval, a number of successful transmissions by other network stations, or a second user-selectable number of consecutive successful transmissions. Additional delay intervals may be added if the network station continues to exceed the predetermined number of consecutive successful transmissions. Burst transmission can also be optimized by counting the consecutive successful transmissions only after detecting an attempted transmission by another network station.
