The real-time traffic comprises a first and second traffic class (HRT, SRT). Real-time traffic of the first and/or second traffic class (HRT, SRT) is transmitted from a transmitter to a receiver. It is detected by the receiver whether an error has occurred during the transmission of the real-time traffic and the error is reported to the transmitter. At least part of the real-time traffic of the second traffic class (SRT) is re-transmitted by the transmitter if the transmitter has received an error report from the receiver within a predetermined time period. | 08-05-2010 |
| 20110041025 | METHOD OF COMMUNICATION, IN PARTICULAR WITH CAPABILITY OF FRAME ABORTION OR RETRANSMISSION INDICATION, BETWEEN A TRANSMITTER AND A RECEIVER BASED ON FRAMES AND CORRESPONDING COMMUNICATION NODE - A method of communicating between a transmitter and a receiver based on frames is provided. An error detection code is added to each frame to be transmitted by the transmitter. The frames to be transmitted by the transmitter are transmitted and the transmitted frames are received by the receiver. An error detection code is re-computed based on the received frames by the receiver. At least one frame which has been correctly received based on a comparison of the error detection code of each frame with the re-computed error detection code of each received frame is acknowledged. An error indication frame is sent by the receiver when an error is detected based on the comparison result. If a retransmission condition is detected by the transmitter by receiving an error indication frame from the receiver or if no acknowledgement frame was received by the transmitter from the receiver in a predetermined time interval, the currently transmitted frame is aborted and the transmitter inserts a trailer. As a further possibility instead of inserting a trailer, the start of retransmission can be indicated by using a retransmission indicator. | 02-17-2011 |

| 20110078255 | METHOD AND SYSTEM FOR MANAGING A CONNECTION IN A CONNECTION ORIENTED IN-ORDER DELIVERY ENVIRONMENT - To manage a connection in a connection-oriented in-order delivery environment, a connection is established between a client and a server in an in-order delivery environment where the message exchange is based on a reliable network and, an unreliable network, also taking traffic classes for real-time operation into account. In comparison to present examples message overhead sequence numbers can be saved and the number of messages can be streamlined and reduced. Further, some error cases are also discussed taking also the bandwidth allocation by forwarding of messages across routers into account. | 03-31-2011 |
| 20110078313 | METHOD AND SYSTEM FOR MANAGING A CONNECTION IN A CONNECTION ORIENTED IN-ORDER DELIVERY ENVIRONMENT - The present disclosure provides a system and method of establishing a connection between a client and a server in an in-order delivery environment. The disclosed system and method includes a client configured to request establishing a connection by sending a first type of message to a server, and the server is configured to confirm the ability of establishing the connection by sending to the client a second type of message leading to the server being connected. The first type of message starts a first client timer measuring a first predefined time period as a first maximum response time and receipt of the second type of message or a data message stops the first client timer. The connection is closed by sending a third type of message. | 03-31-2011 |
| 20110138096 | Methods and Systems for Reliable Link Startup - Link startup systems, methods and devices associated with interconnects are described. Asymmetric lane connections are supported by, for example, independent renumbering of the connected lanes after an initial discovery process. Low-power, hibernating states of devices are supported by, for example, initialing alternating between transmission of startup and wakeup sequences over the interconnect between devices. | 06-09-2011 |
| 20110161777 | Reliable Packet Cut-Through - A cut-through data packet mechanism is described. Forwarding of a cut-through data packet by an intermediary node enables packet transmission of the cut-through data packet to begin prior to performing a frame CRC on the packet. The CRC is instead performed while transmission of the packet is occurring. If one or more errors are found in the cut-through data packet, then a packet trailer indicating such errors is transmitted toward an endpoint node that receives the cut-through packet. | 06-30-2011 |
