Methods and apparatus for supporting active link status during LAN interface reset and reconfigurations. Under one aspect, during normal operations traffic is transmitted over an Ethernet link coupling a first link partner to a second link partner. In response to a network interface re-configuration event, transmission of traffic over the Ethernet link is paused while keeping the Physical layer (PHY) of the Ethernet link active. The configuration of the first link partner is updated while the transmission of traffic is paused and the PHY of the Ethernet link is active. Upon completion of the configuration update, the link partners resume transmission of traffic over the Ethernet link. Additional schemes are provided that support re-configuration of network interfaces that support link and per priority flow control. According to another aspect, separate power domains are used for the PHY and the MAC circuitry, enabling the MAC circuitry to be reset via a power cycle while maintaining power to the PHY circuitry.

The invention relates to a method for detecting a multimedia communication problem. In one aspect, this is implemented by an execution entity, in a processing phase. A message(s) is received that belongs to at least one stream to be monitored relating to at least one media stream. A correspondence between the received message(s) and rule(s) associated with a stream(s) to be monitored is verified. If verified an error detection massage is sent to a checking entity separate from the execution entity, via a rule management entity.

The present application discloses a method for transmitting wireless network data, a sending terminal and a receiving terminal, wherein the method includes: sending data messages to a receiving terminal based on an initial window value and an initial aggregation depth; receiving response messages fed back by the receiving terminal, and determining a current maximum bandwidth and a current window value based on representation information of the response messages; calculating a current maximum aggregation depth according to the current maximum bandwidth; and sending data messages to the receiving terminal according to the current window value and the current maximum aggregation depth, and providing the current maximum aggregation depth to the receiving terminal, so that the receiving terminal feeds back the response messages according to the current maximum aggregation depth. The technical solution provided by the present application can improve the data transmission efficiency.

A wireless transmit/receive unit (WTRU) is configured to, on a condition that a serving grant having a non-zero value is too small for transmission of a single protocol data unit (PDU) from any scheduled medium access control-d (MAC-d) flow, transmit scheduling information (SI). The WTRU is further configured to produce a trigger on the condition that the serving grant is too small and the transmission of the SI is based on the produced trigger.

The present invention discloses a packet control method and a node device, to improve reliability of a data flow in a transmission process. The method includes: After receiving a pause frame, a first node automatically applies, based on adjustment information that is of a send queue of a data flow and that is recorded in a state record set, the pause frame to all queues associated in an adjustment process of the send queue of the data flow. In this way, a packet loss problem in a data transmission process can be avoided without adjusting an XOFF/XON threshold of a receive queue and without increasing a quantity of pause frames in a network system, thereby improving reliability of the data flow in the transmission process.

In one embodiment, a method includes sending a first flow control signal to a first stage of transmit queues when a receive queue is in a congestion state. The method also includes sending a second flow control signal to a second stage of transmit queues different from the first stage of transmit queues when the receive queue is in the congestion state.

A transfer device for coupling a priority signal and a standard signal includes a reception unit configured to receive a plurality of signals transmitted from a device connected to a path different from a forwarding path, a separation unit configured to separate the signals into the priority signal and the standard signal, an identifier reference unit configured to reference an identifier added to the standard signal, an identifier sort unit configured to sort the standard signal by the identifier, a signal coupling unit configured to couple the plurality of standard signals, a multiplexing unit configured to multiplex the priority signal and the standard signal, a priority control unit configured to determine a transfer order of the signals, a transmission unit configured to transmit the signals to a device connected to the forwarding path, an interrupt transfer processing unit configured to perform interrupt processing in a case where the priority signal arrives during transfer of the standard signal, a signal division unit configured to divide the standard signal, an identifier addition unit configured to add the identifier to the standard signal divided, and a transmission suspending unit configured to suspend transfer of the standard signal until transfer of the priority signal is completed.

A user terminal 12-1 can wirelessly or preferentially connect to a router 14 to communicate with an upper network 18, and can communicate with another network 20 via a mobile line. An ONU 16 generates a disconnection notification in a case where congestion exceeding a reference is recognized in the PON communicating with the upper network 18, and generates a connection notification when the congestion is resolved. The router 14 stores the user terminal 12-1 that can communicate with another network 20 among the user terminals 12-1 to 12-4 being connected. In addition, the router 14 disconnects the connection with the user terminal 12-1 that can communicate with another network 20 when the disconnection notification is generated, and attempts reconnection with the user terminal 12-1 that has been disconnected when the connection notification is generated.

In order to implement a method for data flow control in a network with reduced overhead, a first subscriber transmits data symbols in data frames to a second subscriber. The second subscriber forwards and/or processes the data frame. If there is a delay in forwarding and/or processing the data frame, the second subscriber instructs the first subscriber to pause the transmission of the data frames with a granularity of one data symbol. After the pause, the first subscriber continues to transmit the data frames with a granularity of one data symbol.

The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for performing transmission of a SR bundle in a wireless communication system, the method comprising: configuring that the UE transmits a SR bundle, wherein the SR bundle includes repeated transmissions of a SR, starting to transmit the SR bundle to a BS when the SR is triggered, and stopping the transmission of the SR bundle immediately even if at least part of the repeated transmissions of the SR has not yet been transmitted, when SR cancellation condition is met.
