Abstract: A scheduling method includes classifying, by a PC, terminals into delay-sensitive terminals and delay-insensitive terminals according to their traffic types; setting an initial value and a maximum value of a poll failure counter of each of the delay-sensitive terminals; polling each of the delay-sensitive terminals; determining whether there exists a delay-sensitive terminal of which a current value of the poll failure counter is less than the maximum value; and if there exists no delay-sensitive terminal of which the present value of the poll failure counter is less than the maximum value, sequentially polling the delay-sensitive terminals and the delay-insensitive terminals.

Abstract: Disclosed are methods and apparatus for redirecting fiber channel data that is transmitted between a first and a second node, such as a host and target, in a storage area network (SAN) to an intelligent node that facilitates implementation of a service on such redirected data. Such redirection is provided transparently with respect to the first and second nodes without significantly reconfiguring the existing infrastructure of the first and second nodes. In a specific Fiber Channel implementation, the redirection is accomplished without rewiring any of the nodes in the network fabric or reconfiguring zones or virtual storage area networks (VSANs). In general, such redirection is accomplished by rewriting the data as it traverses on a path between the first and second node towards an original destination (e.g., the first or second node) so that the data is redirected to an intelligent node.

Abstract: A data transmission method and apparatus for performing a data transmission between end terminals of a telecommunication network, where the data is transmitted from at least one of the end terminals using the first data bearer. Then, data transmission is switched from the first to the second data bearer, if a predetermined bearer need condition has been determined or in order to obtain a subscriber identity used for gathering charging data. The network service provided by the operator can be improved, since the bearer switching allows an increase of the overall speed of the data transmission, an adaptation of the bearer bandwidth to the data amount, and a provision of the subscriber identity. The first data bearer may be a USSD or SMS data bearer, and the second data bearer may be a circuit-switched data bearer or a GPRS bearer, or vice versa.

Abstract: Techniques for synchronizing routing data include determining whether conditions are satisfied for one-way transfer with an adjacent router. If it is determined that conditions are satisfied for one-way transfer of routing table data with the adjacent router, then a refresh-notice message is sent from the initiating router to the adjacent router. The refresh-notice message includes data that indicates a particular direction for transfer of routing table data. If the particular direction is inbound, then a copy of an adjacent routing table is received without sending a copy of the initiating router's own routing table. If the particular direction is outbound, then a copy of the own routing table is sent without receiving a copy of the adjacent routing table.

Abstract: A high speed data packet switch comprising input and output ports and a switch fabric to link each input port to each output port wherein each connection between input and output ports comprises a dynamic buffer memory for storing at least one data packet for a minimum specified storing time is disclosed. When a data packet is received through an input port, it is written in all individual dynamic memory buffers connected to this input port so as to have a copy of the incoming data packet ready to go through any output port to support unicast, multicast and broadcast traffic. Given the architecture of the data packet switch and its control algorithm, dynamic memory buffers neither need to be refreshed nor their contents have to be restored after reading.

Data of a service different from the transmitted data of the broadcast or multicast service is transmitted via the second downlink physical channel. The MAC layer comprises a first MAC sub-layer handling a dedicated transport channel and a second MAC sub-layer handling a common or shared transport channel.

Abstract: A radio communication scheme applicable to UMTS providing packet data services, such as multimedia broadcast and multicast services (MBMS), to one or more users by modifying (augmenting) certain existing radio communication protocols while employing a new transport channel (a point-to-multipoint DSCH), and/or by establishing new physical downlink shared channels (C-PDSCH and D-PDSCH). An RLC layer is provided in a single CRNC so that the same MBMS can be transmitted to a plurality of terminals via a point-to-multipoint DSCH, without having to repetitively provide many RLC layers in many SRNCs. Alternatively, a C-PDSCH (physical downlink shared channel for control) and a D-PDSCH (physical downlink shared channel for data) are established to allow periodic transmission of MBMS, permitting users to simultaneously access one or more MBMS.

The first network configuration data represents the topology of an upstream part of the data communication network located upstream of the downstream processing module and contains the upstream processing module.

Abstract: A method of interfacing for packet and cell transfer between a first layer device and a second layer device, which includes dividing control information into an in-band portion and an out-of-band portion, transmitting the in-band portion in the data path, and transmitting the out-of-band portion outside of the data path.

Abstract: Communications in a wireless communication system based on two or more communication standards are configured for delivery to cell sites or to subscribers using a digital link having channels assigned to the two or more communication standards. A T-1 level can be divided into twenty four channels that are assigned to two or more mobile standards, and subscriber or network communications based on the two or more standards can be delivered to, for example, radio transmitters associated with the mobile standards. Channel allocation can be revised based upon requested capacity associated with the mobile standards.

Abstract: A method of assigning resources within a network element within which a traffic termination point or AAL2 termination point has been established is described. The network element accepts a connection request, and it is then ascertained whether available resources have sufficient capacity to establish the requested connection. In the event that there is sufficient capacity, it is ascertained whether the termination points defined in relation to the available resources fragments the resources such that the connection cannot be established. If the resources are so fragmented, then one or more of the termination points are reallocated, without breaking the connection to which they relate, thereby defragmenting the resources sufficiently that the requested connection can be established.
