The ethernet switch sends a periodic isotick signal to begin the isochronous interval. Bandwidth remaining after the isochronous interval is then allocated to the IEEE 1394-2000 asynchronous traffic, until the start of the next isochronous interval. | 2010-03-04 |
| 20100054244 | TIME SYCHRONIZATION METHOD AND RELAY APPARATUS - A time synchronization method for synchronizing times of a first apparatus and a second apparatus includes transmitting, by the first apparatus, a packet to the second apparatus, the packet including the time of the first apparatus, providing, by a relay apparatus that relays the packet, a value to the packet, the value indicating a reception time upon the reception of the packet, providing, by the relay apparatus, a difference between the value provided to the packet in the providing of reception time and a current time to the packet upon the transmission of the packet, the difference serving as a delay value, and executing, by the second apparatus, a control for time synchronization based on the time of the first apparatus included in the packet and the delay value provided to the packet. | 2010-03-04 |
| 20100054245 | SYSTEM AND METHOD FOR MULTICASTING IN AN INTERNET PROTOCOL VIRTUAL PRIVATE NETWORK ENVIRONMENT - A method is provided in one example implementation and includes sending a PIM join message to the second spoke router by the hub router. The second spoke router dynamically determines each interested remote spoke router by parsing a hub-sent PIM message and accordingly constructs the multicast routing entry such that the first and second spoke routers establish multicast communication independent of a hub router. In more specific embodiments, the PIM join/prune messaging includes a list of each downstream spoke router that sent a PIM join/prune, in a new attribute. The PIM join/prune message is sent by the hub router towards a multicast source. A new receiver-list attribute is created that the hub router populates with a non-broadcast multi-access (NBMA) address for each interested spoke router. | 2010-03-04 |
| 20100054246 | CONVERGENCE OF MULTICAST TRAFFIC - A multicast data packet sent from a source node is received by a transit node. The multicast data packet includes a source address and a multicast group address. A hardware cache miss is detected at the transit node for the multicast data packet. The multicast data packet is hardware-flooded onto ports of the network. The flooding consists of forwarding a copy of the multicast data packet to neighbor nodes of the transit node based on virtual local area network (VLAN) membership. A cache-miss copy of the multicast data packet is sent to an out-of-line processing unit where it is processed in software. The processing includes establishing, via a hardware abstraction layer, a hardware cache entry for the multicast data packet. The cache-miss copy is not forwarded onto the network. | 2010-03-04 |
| 20100054247 | METHOD AND DEVICE FOR MANAGING MULTICAST GROUPS - A method for managing multicast traffic in a data network, and devices using said method. The hosts store for each multicast group an included source record and an excluded source record, and the network interfaces of the hosts send to the router a message containing information about the included source record and information about the excluded source record. The router also stores for each multicast group an included source record and an excluded source record, and updates them when it receives through its network interface a message from the hosts containing information about an included source list and/or information about an excluded source list. The devices are a router, host equipment and network equipment compatible with the method. | 2010-03-04 |
