Abstract: A network performance monitor for a computer. The performance monitor maintains a baseline for communication paths between a networked computer and other networked computers connected. The network performance baseline is established and maintained by measuring and updating network performance parameters of the communication paths. The network performance parameters are updated using values obtained during time intervals when the communication path consumed a bandwidth approximately equal to its estimated bandwidth. If congestion is detected on the network or the network is underutilized, values of the network performance parameters obtained during that interval are not used to update the network performance parameters. Some performance parameters in the baseline, such as minimum and maximum bandwidth values may be updated by computing a moving average of each parameter. Asymmetric weight values for updating the moving average may be selected based on a direction of change of a value of a network parameter.

Abstract: Embodiments of the invention employ specially adapted P2MP and MP2P transmission techniques to communicate traffic of a TDM based SCADA system over an IP/MPLS based network. Advantageously, by specially adapting P2MP and MP2P transmission techniques to carry TDM based SCADA traffic over an IP/MPLS network, an existing TDM based SCADA system can be migrated to an IP/MPLS network and operated in an easy to manage and bandwidth efficient manner as compared to a solution that employs point-to-point connections between a SCADA master node and subsystems over an IP/MPLS network. Furthermore, since TDM based SCADA equipment would not need to be replaced with IP based SCADA equipment in such a migration, significant equipment and installation costs associated with such replacement can be avoided.

Abstract: In general, techniques are described for measuring packet data unit (PDU) loss in a L2 virtual private network (L2VPN) service, such as a VPLS instance. In one example of the techniques, provider edge (PE) routers that participate in the L2VPN measure known unicast and multicast PDU traffic at the service endpoints for the instance to determine unicast PDU loss within the service provider network. As the routers learn the outbound service (i.e., core-facing) interfaces and outbound local (i.e., customer-facing) interfaces for L2 addresses of customer devices that issue packets to the VPLS instance, the routers establish respective unicast transmit and receipt counters for the service endpoints that serve the customer devices. In another example, PE routers that participate in the L2VPN measure multicast PDU traffic at the service endpoints for the instance and account for internal replication by intermediate service nodes to determine multicast PDU loss within the service.
