Filed:

Feb 15, 2000

Appl. No.:

09/504783

Inventors:

Edmund Colby Munger - Crownsville MD
Douglas Charles Schmidt - Severna Park MD
Victor Larson - Fairfax VA
Michael Williamson - South Riding VA

Assignee:

Science Applications International Corporation - San Diego CA

International Classification:

G06F 15173

US Classification:

709225, 709229, 709245

Abstract:

A plurality of computer nodes communicate using seemingly random Internet Protocol source and destination addresses. Data packets matching criteria defined by a moving window of valid addresses are accepted for further processing, while those that do not meet the criteria are quickly rejected. Improvements to the basic design include (1) a load balancer that distributes packets across different transmission paths according to transmission path quality; (2) a DNS proxy server that transparently creates a virtual private network in response to a domain name inquiry; (3) a large-to-small link bandwidth management feature that prevents denial-of-service attacks at system chokepoints; (4) a traffic limiter that regulates incoming packets by limiting the rate at which a transmitter can be synchronized with a receiver; and (5) a signaling synchronizer that allows a large number of nodes to communicate with a central node by partitioning the communication function between two separate entities.

US Classification:

709241, 709242, 370232, 370234, 370237

Abstract:

Methods and systems allowing a plurality of computer nodes to communicate using weighted transmission paths are provided. A load balancer distributes packets across weighted transmission paths according to transmission path quality, which is monitored and updated from time to time. As transmission quality on a specific transmission path decreases, the weight assigned to that transmission path is reduced. Similarly, weights may be increased if transmission quality improves. The weights assigned to various transmission paths may correspond to a relative number of packets to be transmitted on each respective transmission path. The transmission path for each packet can be selected based on the weights of the various transmission paths. Using weights based on transmission quality, transmission paths with higher transmission quality are used more often than transmission paths with lower transmission quality, resulting in more efficient communications.

International Classification:

B60P 7/02

US Classification:

29610016, 292256, 292DIG 49

Abstract:

A protective cover assembly for covering a space defined by at least one wall. The protective cover assembly includes a plurality of rails coupled to one another to form a frame for securing a material over the space. At least one support bow spans the space to support the material. Clamp mechanisms are coupled to the ends of the support bow for securing the protective cover assembly over the space. The clamp mechanisms include a latch member for engaging the wall and a handle for biasing the latch member against the wall. The clamp further includes a link for interconnecting the support bow to the frame. A collar is coupled to the link for guiding the handle and the latch member between an operational position and a stowed position along the link.

Abstract:

A tonneau cover for selectively enclosing a space within a cargo box. The cover has an elongate channel laterally extending between a proximate end located proximate a side edge of the cover and a distal end at which the channel terminates. The cover includes a clamp mechanism slidably engaged with the channel, and the clamp mechanism includes a handle, a block member slidably received in the channel, an elongate rod member coupled to the handle, and a latch or hook member connected to the rod member. The latch member is moveable between a clamped position for operatively engaging a portion of the cargo box and a released position for spacing the latch member from and placing the latch member out of operative engagement with the cargo box. The handle and rod member are positioned in the channel in the clamp mechanism stowed position.
