Abstract: One embodiment of the invention provides apparatus and a method for handling an incoming packet at a port in a network. The port belongs to one or more partitions, and at least one service level is associated with each of the partitions. When a packet is received at the port, a partition key and a service level are extracted from the packet. The extracted partition key is used to determine the partition to which the received packet belongs. The service level extracted from the packet is then compared against the service level(s) associated with the determined partition in order to authenticate the packet. In another embodiment, the service level is correlated against a destination identifier from the packet instead of the partition key.

Abstract: A system and method for describing multiple packets to a communication module or device without requiring descriptors for each packet. A device driver for the communication apparatus receives a set of packet headers and a set of packet payloads from an upper layer protocol. The headers may be received in a header buffer, and the payloads may be received in a separate data buffer. Or, the packets may be received, in assembled form, in a single buffer. The device driver configures a single descriptor to describe the multiple packets to the communication apparatus. The descriptor includes base address(es) of the buffer(s) in which the headers, payloads or assembled packets are stored, and the lengths of the individual headers, payloads or assembled packets. If the buffer contents are not packed, the descriptor may also include offsets of the headers, payloads or packets.

Abstract: A method and system for buffering media at an initiating station. In response to a user request to initiate a packet-based real-time media session, such as a “push-to-talk” session for instance, the initiating station acquires a data connection. The station then determines that it has acquired a data connection, such as by determining that it has received incoming packet-data, and responsively begins receiving and buffering media, such as voice, from a user. Once the station successfully establishes the requested media session, or a leg of the session, the station then begins transmitting the buffered media to a remote endpoint.

Abstract: A flow control method and system including an algorithm for deciding to transmit an arriving packet into a processing queue or to discard it, or, in the case of instructions or packets that must not be discarded, a similar method and system for deciding at a service event to transmit an instruction or packet into a processing queue or to skip the service event. The transmit probability is increased or decreased in consideration of minimum and maximum limits for each flow, aggregate limits for sets of flows, relative priority among flows, queue occupancy, and rate of change of queue occupancy. The effects include protection of flows below their minimum rates, correction of flows above their maximum rates, and, for flows between minimum and maximum rates, reduction of constituent flows of an aggregate that is above its aggregate maximum. Practice of the invention results in low queue occupancy during steady congestion.

Abstract: The present invention provides a data transfer method for use in a CDMA system operating in the TDD mode. A data signal is transmitted in the form of a data stream of data bursts of different users between a first station and a second station via a multiplicity of antennas, and a reference signal is transmitted in connection with the specific data burst. In a first step, a reference signal is transmitted from the second station to the first station. In a second step, a channel estimation is performed in the first station based on the reference signal that is received from the second station. In a third step, the first station transmits a data burst to the second station via the multiplicity of antennas, it being possible to modify the transmission signals of various antennas having various amplitude and phase factors in accordance with the channel estimation.

This may be implemented in a point to multipoint communications system.

Abstract: Commercially available platforms with performance characteristics are linked with network systems via standardized interfaces. Such a link, however, requires major interventions in the structure of said system. The inventive method reduces the necessary steps by means of a message-based concentration on the network bandwidth or a multiple thereof and a line-based concentration on the bandwidth of one of the peripherals during communication, thereby scheduling at least one interface of the allocated control device.

Abstract: A gateway enables mutual data communication between two or more networks by connecting the networks and forming a bypass path between the two networks to enable data communication therebetween when the gateway does not support a normal data communication mode. The gateway can form at least one physical communication path between the networks through the gateway even if the gateway cannot support a normal communication mode and/or power is interrupted to the gateway. Further, in spite of abnormal conditions, such as abnormal power supply to the gateway, if the bypass path is not formed, a user can compulsorily form the bypass path, thus improving reliability of a network system.
