摘要:
A method of scheduling cells into an asynchronous network for a circuit emulation service, comprises estimating the virtual clock of each connection by on-line traffic measurement, determining the lateness of the head-of-the-line cell for each connection, and giving highest priority to the latest cell.
摘要:
A method is disclosed for traffic policing in packet-based, broadband networks, such as ATM networks. The method comprises the steps of monitoring the arrival of incoming cells, and advancing a reference clock on a step of I if an arrival is late but not later than I, where I is an increment, and if an arrival is later than I assuming a new busy period and setting the reference clock at the arrival time.
摘要:
A method includes providing a first set of location data using a first coordinate system that corresponds to a first building and a second set of location data using a second coordinate system that corresponds to a second building. A third set of location data is generated from the first and second sets of location data by converting the first set of location data from the first coordinate system to a third coordinate system and converting the second set of location data from the second coordinate system to the third coordinate system.
摘要:
A telecommunications system including a plurality of switches defining an Ethernet ring; a plurality of virtual local area networks defined on the Ethernet ring, defining a number of virtual local area networks (VLANs) equal in number to the number of links; and a ring recovery system configured to recover from a link failure by rerouting traffic to a destination on the Ethernet ring via a VLAN not including a failed link
摘要:
A system and method for operating a communications system network, the method including operating an access point (AP) acting as a network controller in a frequency hopping network, the AP communicating with other communication devices of the network over m number of frequencies using a hopping sequence of at least some of the m number of frequencies and a dwell time d for the plurality of frequencies; and operating a communication device seeking to establish synchronized communication with other communication devices of the frequency hopping network without any cross-AP coordination, the communication device scanning all of the m number of frequencies using a scanning time s for each of the m number of frequencies; and, wherein the scanning time s is no greater than 1/m of the AP dwell time d.

摘要:
A method and system, the method including determining a frequency quality measurement value for each of a plurality of frequencies a network coordinator can use in a frequency hopping sequence for communicating with a client, classifying each of the plurality of communication frequencies into one of a plurality of different categories based on a relative ranking of the determined frequency quality measurement value of each of the plurality of frequencies, generating, by the network coordinator, a frequency hopping sequence to be used for communication between the network coordinator and the client, the generated hopping sequence including only select frequencies from the plurality of frequencies in a predetermined number of future time slots that minimize a probability of a predetermined number of consecutive frequency hop failures in the predetermined number of future time slots, and notifying the client of the generated frequency hopping sequence to be used for communication.
摘要:
A method includes displaying a reference polar coordinate system on a display screen, and displaying a radiation pattern image on the display screen in juxtaposition with the displayed reference polar coordinate system. In another aspect, an angled line is drawn on a display screen to represent the proposed layout of a leaky coaxial cable. A point of interest is selected that is spaced from the proposed cable layout, and one of the segments of the cable is determined as likely to produce a dominant level of irradiation with respect to the point of interest.
