20080205395 | Receiving multicast traffic at non-designated routers - A multicast stream is received. At a non-designated router, a multicast stream is received with respect to which the non-designated router is not a designated router responsible for sending the multicast stream to a host. The received multicast stream is discarded. | 08-28-2008 |
20100303071 | SYSTEM AND METHOD FOR CONVERTING UNICAST CLIENT REQUESTS INTO MULTICAST CLIENT REQUESTS - A system and method converting a unicast client request into a multicast client request is provided, the method comprising: receiving the unicast client request; mapping the unicast client request destination IP address and unicast client request destination port to a multicast record, wherein the multicast record contains a multicast destination internet protocol (IP) address and wherein the multicast destination IP address corresponds to the unicast client request destination IP address and unicast client request destination port; and transmitting the multicast client request that mirrors the received unicast client request to a plurality of destination servers using the multicast destination IP address that corresponds to the unicast client request destination IP address and unicast client request destination port. | 12-02-2010 |
20110044339 | SERVER-SIDE LOAD BALANCING USING PARENT-CHILD LINK AGGREGATION GROUPS - Various exemplary embodiments relate to a method and related network node including one or more of the following: establishing, at the network node, a first Child Link Aggregation Group (CLAG), wherein the first CLAG includes at least one link to a first downstream node; establishing, at the network node, a second CLAG, wherein the second CLAG includes at least one link to a second downstream node; establishing, at the network node, a Parent Link Aggregation Group (PLAG), wherein the PLAG includes the first CLAG and the second CLAG; receiving, at the network node, a packet including an address of a destination of the packet; determining that the destination of the packet is associated with the PLAG; and transmitting the packet over both the first CLAG and the second CLAG. | 02-24-2011 |
20110293021 | PREVENT AUDIO LOSS IN THE SPLICED CONTENT GENERATED BY THE PACKET LEVEL VIDEO SPLICER - A method and apparatus for packet level splicing of transport streams including encrypted content wherein the audio packets having a presentation timestamp (PTS) value greater than that of a last video frame within the primary or from-stream are dropped prior to splicing. | 12-01-2011 |
20110296437 | METHOD AND APPARATUS FOR LOCKLESS COMMUNICATION BETWEEN CORES IN A MULTI-CORE PROCESSOR - A lockless processor core communication capability is provided herein. The lockless communication capability enables lockless communication between cores of a multi-core processor. Lockless communication between a first core and a second core of a multi-core processor is provided using a message queuing mechanism. The message queuing mechanism includes a message queue, a first bitmap, and a second bitmap. The message queue includes a plurality of messages configured for storing data queued by the first core for processing by the second core. The first bitmap includes a plurality of bit positions associated with respective messages of the message queue, and is configured for use by the first core to indicate availability of respective queued message data. The second bitmap includes a plurality of bit positions associated with the respective messages of the message queue, and is configured for use by the second core to acknowledge availability of the respective queued message data and to indicate reception of the respective queued message data. | 12-01-2011 |
20120009895 | METHOD AND APPARATUS FOR RELIABLE TRANSMISSION OF CHARGING DETAIL RECORDS - A charging detail record transmission capability is provided herein. A mobile gateway (MG) generates charging detail records (CDRs) intended for delivery to a charging gateway function (CGF). The CDRs are propagated toward both a first and second charging data function (CDFs). The first and second CDFs buffer the CDRs. The first CDF is configured for propagating CDRs toward the CGF. The second CDF is configured for propagating CDRs toward the CGF when the first CDF fails. The CGF is configured for acknowledging receipt of CDRs to the first or second CDF from which the CDRs are received. The first CDF is configured for acknowledging, to the second CDF, receipt of acknowledgment messages from the first CDF. The second CDF is configured for, upon failure of the first CDF, initiating a process for determining which of the CDRs buffered at the second CDF need to be propagated to the CGF in order to ensure that none of the CDRs generated by the MG are lost due to the failure of the first CDF. | 01-12-2012 |
