US Classification:

Abstract:

A scheduling system and methodology for use in a network switch element having multiserver, multiple-arbiter architecture. Ingress ports and egress ports coupled to the cross-connect fabric of the network element are provided with multiple ingress and egress arbiters, respectively, for effectuating an iterative arbitration strategy such as RGA or RG. Arbiter architectures include singe-arbiter-per-port; single-arbiter-per-server; multiple-arbiters-per-port; and multiple-arbiters-per-server arrangements, wherein the arbiters can be implemented using RRA, BTA, Flexible Ring, or any other arbiter technology. Depending on the iteration strategy, ingress arbiter architecture and egress arbiter architecture, a variety of iterative, multiserver-capable scheduling algorithms can be obtained, which scheduling algorithms can also be implemented in QoS-aware network nodes.

International Classification:

H04L 12/54

US Classification:

370374, 370383

Abstract:

A look-up table (LUT)-based arbitration (LTA) system and methodology for use in a network switch element. Input control signals generated by ingress and egress entities associated with a cross-connect matrix of the network switch element are encoded into address information that is used for interrogating a storage structure. Pre-computed arbitration results based on a select arbiter scheme are stored into fields associated with the storage structure. When a particular input combination is applied with respect to an arbitration iteration, a selected arbitration result is obtained by querying the appropriate field, which is then decoded into a corresponding selected entity for the arbitration iteration.

US Classification:

370238, 370252

Abstract:

A selective, flow-based datapath architecture is described. A Flow Control Block Manager (FCBM) is located in a flow-based datapath for selectively and intelligently processing packets in the Flow Path. If, according to the FCBM, efficiency gains can be achieved by creating a flow control block and employing flow-based processing on a packet stream, the packets are processed accordingly. If, however, insufficient gains are anticipated the packets are processed in a flow-unaware manner. The FCBM determines the manner in which to process packets based on a set of criteria.

Appl. No.:

11/383741

Inventors:

Gerard Damm - Plano TX, US

Assignee:

Alcatel Lucent - Paris

International Classification:

H04J 1/16

US Classification:

370252

Abstract:

Performance measurements for a network, such as delay, delay variation, and loss, are performed over layer-2. A PM frame is sent from a source MEP (Maintenance End Point) to a destination MEP. The PM frame is timestamped immediately prior to transmission, and the local clock at the destination MEP is noted immediately upon arrival. MIPs (Maintenance Intermediate Points) may also time stamp the PM frame. Preferably, each PM frame has an interval (session) identifier and a sequence number within the interval. The PM frames are received by and sent by PM modules within the nodes of the network. The PM modules include a Sender function for sending an interval of one or more PM frames and a Receiver function for receiving PM frames and computing measurements.

International Classification:

US Classification:

370216

Abstract:

A bridge/router and method are described herein that are capable of avoiding packet replication at layer 2 where there is a failure in a network. In one embodiment, the bridge/router is informed about a fault which occurred within the network. Then, the bridge/router makes a determination about whether or not multiple LSPs would be used to flood/carry the same IP traffic out off a single port. If yes, the first bridge/router chooses one of the LSPs to carry the IP traffic out the single port and then prevents the IP traffic from being carried on the remaining LSP(s) out the single port which avoids the packet replication on a link which is associated with the single port. If no, then the first bridge/router allows the IP traffic to be carried on the LSPs out off more than one port.

Abstract:

A diagnostic tool and method are described herein that are capable of diagnosing and localizing a multicast connectivity flow fault within a layer aggregation network. In one application, the diagnostic tool and method can be used by a customer service representative to diagnose why a customer cannot receive a television channel even though they can receive other television channels within an IPTV network.

Abstract:

A computer-implemented method for facilitating DHCP diagnostic functionality comprises a plurality of operation. An operation is performed for identifying misconfigurations to a DHCP option configuration of a DHCP agent between a DHCP server and a client of the DHCP server. An operation is performed for confirming proper address concentration configuration with respect to the DHCP agent. An operation is performed for snooping on address assignments from the DHCP server to the client of the DHCP server to determine unauthorized ones of the address assignments.

Abstract:

A method and system for logical group endpoint discovery in a data communication network is disclosed. A network endpoint receives from a source a request identifying a logical group and determines whether a port associated with the endpoint is a member of the logical group. If a port associated with the endpoint is a member of the logical group, the endpoint transmits to the source a reply identifying the port and the logical group. The request may be multicast while the reply may be unicast. The logical group may be a VLAN or a multicast group. The source and endpoint are preferably 802. 1ag maintenance endpoints. The request may include an IEEE 802. 1ag continuity check multicast address as a destination address.
