Abstract: A system and method for receiving, from one or more ingress routers, a first set of records including data corresponding to network traffic, receiving, from one or more egress routers, a second set of records including data corresponding to network traffic and creating a multicast traffic matrix using at least a portion of the data included in the first and second sets of records.

Abstract: A method of and system for monitoring traffic in a multicast network including determining at a first time a first packet count representing a quantity of packets associated with a multicast group transmitted from at least one source, and received by a router, determining at a second time a second packet count representing a quantity of packets associated with the multicast group, transmitted from the at least one source, and received by the router, the second time being after the first time, comparing the second packet count to the first packet count, and initiating an alarm in response to the second packet count being less than a predetermined value greater than the first packet count. A status for multiple routers can be obtained, comprising a difference between the quantity of the first and second packet counts, and indicating a warning in response to at least one of the plurality of router status being less than the predetermined value.

Abstract: A system for allowing a wide selection of components to affect a desired result in the positioning business. Up to nine axes of coordinated motion are offered each of which may use a servomotor, a single or double rod air cylinder. The control for the system is a series of digital commands that cause the cylinder to accelerate, decelerate, maintain a given velocity, stop or pause and repeat a series of commands. It uses a low power servo system which, when activated, opens an air valve to an air cylinder which then moves until the valve actuator is turned off by the cylinder thus causing the air cylinder to follow the lower power servo system.
