Abstract: A switching node (3) for providing admission control in a network comprises a number of separate priority queues (6) for receiving packets having different priority levels. Priority levels (1) to n provide guaranteed delay services, priority levels n+1 to m provide guaranteed loss services, and priority level Pm+1 provides best effort service. Measuring means 51 to 5m continually measure the average bit rate entering each priority level buffer P1 to Pm, except the lowest Pm+1. When a request arrives with a kth priority level, the network capacities for priority levels l=k..Pm are calculated. For all choices of l, the measurements of traffic loads of levels l and higher are taken into account. These capacity requirements are necessary to guarantee the quality of service for all flows already admitted to the lower priority queues. These capacities are compared to the network capacity, and if there is sufficient capacity, the request is accepted. Otherwise, the request is rejected.

Abstract: The invention relates to a method and a system for congestion management in a Frame Relay network. The method comprises determining the virtual channel associated with a frame to be transmitted when it is received at a network node. In order for the relay capacity of the network to be equitably divided between all subscribers (a) data is buffered at the input boundary of the subscriber node to virtual-channel-specific buffers (621...62n), (b) congestion notifications (M) are transmitted in a backward direction from the network nodes to the subscriber node of the virtual channel whose frame is received at that particular moment, and (c) the amount of traffic supplied towards the network from the subscriber node buffer corresponding to said virtual channel during a certain interval having a predetermined length is controlled on the basis of the contents of congestion notifications (M) received from the network during said interval.

Abstract: A virtual reality system has a database for defining one or more three-dimensional virtual spaces. A communication unit establishes a communication between the database and a user, and a data communication unit communicates data from the database to the user so that the user's computer may display a portion of a selected virtual space on the user's head mounted display. The communications unit also receives data corresponding to the position, orientation, and/or movement of the user relative to a reference point and uses the data to define a virtual being within the virtual space, wherein the position, orientation, and/or movements of the virtual being are correlated to the received data. Preferably, the data communicated to the user typically corresponds to the portion of the virtual space viewed from the perspective of the virtual being. The system defines other virtual beings within the database in response to position, orientation, and/or movement data received from other users, and the portions of the virtual space communicated to the other users may correspond to the perspectives of their associated virtual beings. The system periodically updates the database and communicates the updated portions of the database to the users to reflect changes in perspective of the virtual beings and changes in the position of moving objects within the virtual space. The system also supports audio communication with the users. To reduce the amount of data communicated between the computer and each user, visual and sound priority spaces may be defined within the portion of the virtual space data communicated to the user, and elements within selected priority spaces may be updated in priority over other priority spaces.

Abstract: Techniques for managing preamble transmission and processing on a shared communication medium are disclosed. An access point or an access terminal, for example, may generate a preamble for silencing communication on a communication medium with respect to an upcoming data transmission, configure the preamble to identify one or more target devices for the silencing, and transmit the preamble over the communication medium in advance of the data transmission. Conversely, the access point or the access terminal may receive a preamble (as a receiving device) over a communication medium, identify one or more target devices for silencing communication on the communication medium with respect to an upcoming data transmission based on the preamble, and selectively silence communication over the communication medium based on itself (as the receiving device) being among the one or more target devices.

Abstract: Techniques are disclosed to increase security of a wireless access point (WAP). In embodiments, a cellular network provider has an arrangement with an owner of a WAP for cellular network customers to connect to the Internet through that WAP. The WAP may broadcast a SSID for cellular network customers only when a virtual private network (VPN) is established between the WAP and a server of the cellular network provider. If the VPN disconnects, then the WAP stops broadcasting this SSID until the VPN is reestablished.

Abstract: In order to provide flexible scaling and dynamic reconfiguration, a wireless local area network controller includes a virtual dataplane with one or more virtual machines. These virtual machines pre-calculate processing parameters for packets in a data flow. For example, the pre-calculated processing parameters may include: encapsulation parameters, quality-of-service parameters and priority parameters. Subsequently, when one of the virtual machines receives a packet in the data flow on an input port, the virtual machine modifies information in a header of the packet based on one or more of the pre-calculated processing parameters and information associated with the data flow (which specifies the one or more pre-calculated processing parameters). Then, the virtual machine transmits the packet on an output port. In this way, the virtual machine maintains a fixed inter-packet time between packets in the data flow.

Abstract: A message flow shaping approach for a network element capable of message routing is presented. The network element is configured to receive one or more logical ingress message flows and to output one or more logical egress message flows, wherein a flow priority level is allocated to each ingress and egress message flow. A method implementation of the technique presented herein comprises the step of the determining a message flow congestion state per flow priority level at an egress side of the network element. The method further comprises the step of triggering a message flow shaping operation. The message flow shaping operation is triggered per flow priority level at an ingress side of the network element dependent on the congestion state determined for at least one associated flow priority level at the egress side.
