The Internet technology as approved by the IETF organization has defined different services. One is the integrated services (IntServ) and the other the differentiated services (DiffServ) architecture. Another is the RSVP Protocol according to which Quality of Service can be implemented with accuracy and richer functionality. | 01-21-2010 |
20100115384 | METHOD FOR PACKET-SWITCHING TRANSMISSION OF MEDIA DATA AND DEVICE FOR PROCESSING MEDIA DATA - The invention relates to a method for packet-switching transmission of media data and a device for processing media data. Media data may be video, audio or text data, or other data. Transmission of the data is usually effected according to a streaming method. The data is therein transmitted in packets and re-assembled in the receiving device. For Internet applications, the real-time transport protocol is very widely used in the transmission of data streams. However, this data transmission protocol does not enable a secure transmission which is based on a repetition of the defectively transmitted data. Sequence counters are used according to this protocol so that left-out data packets can be detected in the receiving device. According to the invention, it is provided that error information data is inserted in the destination media data record which is generated from the received data in the receiving device when, according to the transmission protocol, transmission errors are detected in the analysis of the data packets received. The transmission errors are then documented in the destination data record. The stored error information can be analyzed upon reproduction of the destination data record so that it can be evaluated, in particular, whether the recorded original data is so seriously defective that a new recording is inevitable. In particular, this is advantageous in video production where it is necessary to quickly evaluate whether a recorded film or video scene is of acceptable quality (if necessary, taking potential retouching into account) or whether it must be repeated and recorded again. | 05-06-2010 |
20100135332 | METHOD FOR SYNCHRONIZING A CLOCK OF A NETWORK COMPONENT WITH A CLOCK OF FURTHER NETWORK COMPONENT AND NETWORK COMPONENT THEFOR - The invention relates to a method for synchronizing a clock of a network component with a clock of a further network component communicatively connected to the network component in a network and a network component, whereby the method comprises the following steps: determining a set of forward transition delays for transmission of messages from the network component to the further network component and a set of corresponding backward transition delays for transmission of messages from the further network component to the network component, selecting a minimum forward transition delay from the set of forward transition delays, selecting a minimum backward transition delay from the set of backward transition delays, deriving an estimated value for an offset between the clock of the network component and the clock of the further network component from the selected minimum forward transition delay and minimum backward transition delay, and adjusting the clock of the network component in accordance with the estimated value for the offset estimate. | 06-03-2010 |

20110096849 | OPTIMIZED SELECTION OF TRANSMISSION PROTOCOL RESPECTING THRESHOLDS - In the method for management of data transmissions in a network, switching means are provided, by means of which a change can be carried out between a first data transmission type and a second data transmission type, as alternative data transmission types between a transmitter and a receiver. The change is carried out on the basis of at least one respectively predetermined criterion. The first data transmission type corresponds to a transport protocol based on rate-based overload control. The second data transmission type corresponds to a transport protocol based on RTT-based overload control. | 04-28-2011 |
20110099178 | Method for providing a table of station-specific information in a network of distributed stations, and network station for carrying out the method - After every bus reset operation in an IEEE 1394 network, the network is reconfigured. This involves a table with further station-specific information being created after the bus initialization phase, the tree structure identification phase and the self identification phase. This is done by making requests to the individual network stations. Each network station returns its station-specific information to the requesting network station. It has become apparent that in some cases a response from the network station to which a request has been sent is returned only after the request has been repeated a plurality of times or in the extreme case even not at all. So as not to delay the creation of the network node information table unnecessarily for such cases, the invention proposes creating the table in two phases. In the first phase, all that information which has been received up to a time determined by a first abort criterion is sorted into the table. Next, the still incomplete table is enabled for use by an application program in the requesting network station. In the second phase, the still missing station-specific information is then requested again and is sorted into the table when it is delivered by the stations to which requests have been sent. After a time determined by a second abort criterion, the further request for the still missing station-specific information is terminated and the table is closed in this state and is provided for use by the application software. | 04-28-2011 |
20120102243 | METHOD FOR THE RECOVERY OF A CLOCK AND SYSTEM FOR THE TRANSMISSION OF DATA BETWEEN DATA MEMORIES BY REMOTE DIRECT MEMORY ACCESS AND NETWORK STATION SET UP TO OPERATE IN THE METHOD AS A TRANSMITTING OR,RESPECTIVELY,RECEIVING STATION - In the method, data are transmitted between a first memory allocated to a source computer and a second memory allocated to a target computer via a network by remote direct memory access. On the source computer side, a predetermined number of directly consecutive transmission buffers is selected from a continuous buffer memory area and transmitted in a single RDMA transmission process to the target computer. On the target computer side, an RDMA data transfer is executed over the entire continuous buffer memory area and a buffer sequence procedure. The buffer sequence procedure causes the received buffers to be supplied to the target application in the transmitted sequence. | 04-26-2012 |
20120219014 | METHOD AND SYSTEM FOR IMPLEMENTING QUALITY OF SERVICE MANAGEMENT IN INFINIBAND NETWORKS - The present invention relates to a method and a system for processing image data. The method includes receiving a request by a quality of service QoS manager from a user application to reserve bandwidth for transmitting data over the network. The method further provides for acquiring a network representation by the QoS manager from a subnet manager for evaluating network bandwidth for transmitting the data over the network. The method also performs the steps of sending a request by the QoS manager to the subnet manager to set network parameters if network bandwidth is available sufficient for transmitting the data over the network, and converting the network parameters by the subnet manager into subnet management packets SMPs. Finally, the method provides for allocating by the QoS the network, the bandwidth for transmitting the data. | 08-30-2012 |
