20120093161 | METHOD AND SYSTEM FOR TAGGING PACKETS ROUTED TO CUSTOMER PREMISES DEVICES VIA CLUSTERS OF DEDICATED CUSTOMER INTERFACES - A method of routing traffic to customer premises devices (CPDs), each CPD being reachable via a dedicated customer interface (DCI) from among a plurality of DCIs grouped into clusters included in respective outside plant units (OPUs). Packets destined for the CPDs are received. A destination DCI and a destination OPU for each packet is determined. The destination DCI for a particular packet destined for a particular CPD is determined by identifying the DCI via which the particular CPD is reachable. The destination OPU for the particular packet is determined by identifying the OPU that includes the destination DCI. For each particular OPU that is the destination OPU for one or more packets, the packets are buffered and transmitted via an interface for the particular OPU. For each particular DCI that is the destination DCI for one or more packets, tagging each packet with an indication of the particular DCI. | 2012-04-19 |
20120093162 | REORDERING PACKETS - There are disclosed processes and apparatus for reordering packets. The system includes a plurality of source processors that transmit the packets to a destination processor via multiple communication fabrics. The source processors and the destination processor are synchronized together. Time stamp logic at each source processor operates to include a time stamp parameter with each of the packets transmitted from the source processors. The system also includes a plurality of memory queues located at the destination processor. An enqueue processor operates to store a memory pointer and an associated time stamp parameter for each of the packets received at the destination processor in a selected memory queue. A dequeue processor determines a selected memory pointer associated with a selected time stamp parameter and operates to process the selected memory pointer to access a selected packet for output in a reordered packet stream. | 2012-04-19 |
20120093163 | METHOD OF CONTROLLING ACCESS OF DEVICES TO COMMUNICATION MEDIUM IN DISTRIBUTED NETWORKS - Method of controlling the access of devices to the communication media in distributed networks of CSMA (Carrier Sense Multiple Access) type is characterized by that each time before the packet transmission attempt, if the communication medium is detected to be idle, the prespecified fixed time interval equal to the minimum interpacket space is timed out during which the random numbers of time slots defining the order of media access are selected from the fixed number of slots of equal width using the pseudorandom number generator in every node where the probability of a selection of a particular slot is geometric with a characteristic parameter defined as the ratio of the probability of a selection of a given slot to the probability of a selection of the next slot, which changes from zero to one as a discrete function of the state of the node's counter, and after that the time interval of random delay corresponding to the selected random is assigned. After the minimum interpacket space the phase of known sequential priority access is started and subsequently, the random delay assigned previously is timed out and at the same time the state of the communication medium is sensed again, and if the communication medium is still sensed idle, it is made available to the node with the lowest number of the slot randomly selected. After completing a given packet reception, the states of the counters in all the nodes in a given network segment are increased by the increment defining the number of expected packets that will be generated in a result of the reception of the transmitted packet reduced by one, and next, the cycle is repeated. During the data packet transmission the collisions are detected optionally in the communication medium by the collision detectors, and next, the states of the counters are changed in the nodes with the use of the corresponding control signals obtained from the collision detectors, and in case the communication medium is detected to be idle after the time equal to the sum of the minimum interpacket space and the time delay defined by the prespecified fixed maximum number of slots, the states of the counters in all the nodes in a given network segment are decreased by one with the use of the control signals obtained from the communication medium state detectors. | 2012-04-19 |
20120093164 | Method and Apparatus for Generating Constraint Route - A method and an apparatus for generating a constraint based routing are disclosed in the present invention. The method includes: when computing a routing with a constraint condition, directly computing paths from a head node to a tail node of the routing, and comparing the paths that are computed with the constraint condition of the routing, and adding one or more paths which satisfy the constraint condition of the routing to a result set of routing computation.

20120093165 | METHOD AND NODE DEVICE FOR NEGOTIATING ASSOCIATED CHANNEL CAPABILITY BETWEEN NODES - The present invention includes: receiving a Path message that is sent by an upstream node and carries an ACH capability of the upstream node; creating a new Path message and sending the new Path message to a downstream node, where the new Path message includes the ACH capability of the upstream node; receiving a Resv message that is sent by the downstream node and carries information about an ACH capability of the downstream node; and creating a new Resv message and sending the new Resv message to the upstream node, where the new Resv message includes the ACH capability of the downstream node. In the embodiments of the present invention, the ACH capability can be negotiated between nodes on an LSP so that a node on the LSP can know an ACH capability of another node, which avoids loss or erroneous forwarding of a special packet transmitted on an ACH. | 2012-04-19 |
