The router uses the identification information to consult access data stored for the client node and returns an acknowledgement message to the access node, indicating whether access is permitted. If access is granted, the access node streams the multicast channel to the client node. Modifying the multicast request message using the access node to include identification information allows the access control to be performed in a more centralized manner while retaining the security of a port-based access control. | 2011-06-23 |

The transit level router components receive the forwarded packet and forward the packet to a respective network. The mapping, or other assignment, of portions of the FIB associated with the distributed routing environment is managed by a router management component. | 2011-06-23 |
20110149965 | DISTRIBUTED ROUTING ARCHITECTURE - A hierarchical distributed routing architecture including at least three levels, or layers, for receiving, processing and forwarding data packets between network components is provided. The core level router components receive an incoming packet from a network component and identify a distribution level router component based on processing a subset of the destination address associated with the received packet. The distribution level router components that receiving a forwarded packet and identify a transit level router component based a second processing of at least a subset of the destination address associated with the received packet. The distribution level router components maintain address routing information a first and second memory. The transit level router components receive the forwarded packet and forward the packet to a respective network. The mapping, or other assignment, of portions of the FIB associated with the distributed routing environment is managed by a router management component. | 2011-06-23 |
20110149966 | Header Processing Engine - Roughly described, a header processing engine for a network interface device has a header recognizer to parse the headers of a data packet stored at a buffer to identify the type and position of each header in the packet; a constructor unit; and a processor including an execution pipeline. The header recognizer is configured to, for each header: select in dependence on the header type commands stored at a command memory; and form one or more messages for the constructor unit identifying the selected commands and the position of the header in the data packet. The commands selected for the packet headers are collectively such as to, if executed by the constructor unit, cause the constructor unit to generate a data structure which operates to cause the processor to process of the packet headers without accessing the data packet at the buffer. | 2011-06-23 |
20110149967 | SYSTEM AND METHOD FOR TRANSMITTING NETWORK PACKETS ADAPTED FOR MULTIMEDIA STREAMS - A system and a method for transmitting network packets are provided. The system includes an information module, a scheduling module, and a forwarding module. The information module receives and records media information of a plurality of multimedia streams. The scheduling module calculates a guaranteed bit rate of each multimedia stream according to the media information provided by the information module, and rearranges isochronous packets of the multimedia streams in the first time slots of a plurality of clock cycles according to the guaranteed bit rates so that the transmission of the isochronous packets satisfies the guaranteed bit rates. The length of each clock cycle is a predetermined length. The length of the first time slot and the predetermined length are in a predetermined ratio. The forwarding module transmits all the packets of a clock cycle to a network at every a time interval of the predetermined length. | 2011-06-23 |
20110149968 | METHOD FOR CONTROLLING INTERNET NETWORK - An Internet network control method is disclosed. When an inter-layer interworking occurs in the Internet network, an upper layer transmits control information on layers related to the interworking to the layers. Therefore, a uniform system for packet exchange in the Internet network is provided. Additionally, since a packet header of a packet transmitted among the layers includes an identifier (ID) regarding a slice, information may be distributed in a centralized system or a distributed system. | 2011-06-23 |
20110149969 | Method of Controlling Data Propagation Within a Network - The present invention provides a method of limiting the frequency of floods within a data network, the floods arising as a data frame is routed to an unknown destination, the method comprising the steps of: (a) receiving ( | 2011-06-23 |
