20080198740 | Service take-over system of multi-host system and method therefor - A service take-over system of a multi-host system and a method therefor are provided, in which the multi-host system includes a service host and at least one standby host with their operating state monitored mutually via a heartbeat mechanism. When the service host for providing a service externally fails, an external public IP address for providing a service externally of the service host is taken over to a standby host. A service environment required for taking over the service of the service host to the standby host is prepared. The preparation state of the service environment is detected, and access request data packets via the external public IP address to the service are dropped before the service environment gets ready. The service is taken over after the service environment is ready, and the access request data packets to the service are received, so as to provide the service externally. | 2008-08-21 |
20080198741 | Method for Providing Alternative Paths as a Rapdid Reaction to the Failure of a Link Between Two Routing Domains - The present disclosure relates to a method for providing substitute routes in rapid response to the failure of a link between two routing domains in a packet-oriented network. After the failure of a link has been identified, substitute routes are provided for routes which have been interrupted by said failure by locally selecting alternative routes and propagating messages along the substitute routes. In order to provide substitute routes, an inter-domain router checks whether the router contains a substitute route. If there is no substitute route, a request message is transmitted to at least one adjacent inter-domain router and the transmission of at least one substitute route is thus requested. If there is a substitute route in the adjacent inter-domain router, the inter-domain router making the enquiries is informed of this in a response message. The present disclosure thus results in the improved provision of substitute routes in response to disruptions in inter-domain routing. | 2008-08-21 |
20080198742 | METHOD AND SYSTEM FOR TESTING STATEFUL NETWORK COMMUNICATIONS DEVICES - The testing of stateful network devices at near wire-speed operation is accomplished by a tester that delivers realistic client-side and the server-side traffic to stateful network device under test, where the realistic traffic can simulate legal packets of a plurality of TCP sessions that are expected to be transferred over each connection between the tester and the device under test. The simulated traffic in a session is independent of previous states of the session or received packets. The packets are generated by the tester based on a predefined scenario. The scenario can define the type of the session (http, ftp, email, any combination of those, etc.) the content, the size of a message, number of connections in the session, missing packets, bit rates, etc. For each scenario, one or more scripts can be created. The scripts can simulate problems so that the operation of the device under test can be monitored. | 2008-08-21 |
20080198743 | DATA FLOW CONTROL FOR SIMULTANEOUS PACKET RECEPTION - Embodiments of the present invention provide methods, a module, and a system for calculating a credit limit for an interface capable of receiving multiple packets simultaneously.

20080198744 | ACCESS CONTROL FOR PACKET-ORIENTED NETWORKS - The invention relates to a method for access control to a packet-oriented network. An admissibility check for a group of packets is carried out by means of a threshold value for the traffic volume between the network input node and the network output node for the flow. The transmission of the groups of data packets is not permitted when an authorisation of the transmission would lead to traffic volume exceeding the threshold value. A relationship between the threshold values and the traffic volume in partials stretches or links may be formulated by means of the proportional traffic volume over the individual partial stretches. Using the capacities of the links the threshold values for pairs of input and output nodes can be fixed such that no overload occurs on the individual links. Within the above method a flexible reaction to the drop-out of links can be achieved by means of a resetting of the threshold values. Furthermore the inclusion of other conditions is possible, for example relating to the capacity of interfaces to other networks or special demands on transmission of prioritised traffic. | 2008-08-21 |

If r has a predetermined relationship to f, then the UDP packet is added to the dispatch queue, otherwise the UDP packet is discarded. The value for f is based on the current dispatch queue load, the network quality, the retransmission rate, and the allowable drop rate. Thus, the determination as to whether to drop UDP packets or not is configurable by an administrator and also adaptable to the current network and dispatch queue conditions. | 2008-08-21 |

20080198836 | Method and Apparatus For Synchronization in Wireless Communication System - For a transmission signal for a wireless communication system and a method and apparatus for performing synchronization processing for the transmission signal provided by the present invention, the principal ideas is that, a synchronization sequence is respectively inserted into a group of transmission datum according to predetermined time offsets to form a group of transmission signals. The synchronization sequences inserted into the transmission datum are obtained respectively by performing a phase modulation for the same known basic synchronization sequence according to the predetermined phase offsets, dispersed in the same transmission signal period without overlapping with each other, and transmitted by different transmit antennas. By using the transmission signals and the structure of their synchronization sequences, the receiver side only needs to search a part of the received signals, then one of an expected group of synchronization sequences, served as the main synchronization sequence, can be acquired quickly, and based on this, the synchronization positions of the transmission signals from other transmit antennas can be estimated, at the same time, by using the phase offsets between the synchronization sequences and the basic synchronization sequence, the transmission signals from different transmit antennas can be distinguished effectively. | 2008-08-21 |
20080198837 | System and method for transmitting and receiving signal in communication system - Disclosed is a method for transmitting and receiving a signal in a communication system, and a system for supporting the method. To this end, a first communication system transmits data during a first time slot and receives data during a third time slot, and a second communication system, differing from the first communication system, transmits data during a second time slot and receives data during a fourth time slot. The first and second time slots are defined by downlink frame transmission intervals which exist in the entire frame transmission interval allocated for the first communication system, and the third and fourth time slots are defined by uplink frame transmission intervals which exist in the entire frame transmission interval allocated for the first communication system, wherein the first to fourth time slots do not overlap each other. | 2008-08-21 |
20080198838 | APPARATUS AND METHOD FOR SOFT MEDIA PROCESSING WITHIN A ROUTING SWITCHER - A routing switcher performs various soft signaling processing within the router using one or more internal soft media processors (central processing units) to enable flexible solutions. The routing switcher includes a plurality of inputs and outputs operably connected by a cross-point matrix where the inputs are dynamically coupled to one or more of the outputs. The routing switcher also includes a soft media processor connected to the cross-point matrix as well as being dynamically coupled between some inputs and outputs. The soft media processor receives a signal from an input via the cross-point matrix and performs one of at least two signaling processing functions resident on the soft media processor and outputs a processed signal from one or more of the routing switcher's outputs. | 2008-08-21 |
