  • Patent number: 11218393
    Abstract: A method for performing a performance measurement on a multipoint packet flow transmitted in a packet-switched subnetwork. A monitoring network of measurement points is implemented in the subnetwork. All packets have a marking value, which is periodically switched between first and second marking values. Each measurement point receiving a marked packet updates a couple of performance parameters, one per each marking value. Since not all the measurement points receive the same packets of the multipoint packet flow, to provide a performance measurement a cluster of measurement points is firstly identified in the monitoring network, which possesses the following property: each packet received at the input of the cluster is also received at the output of the cluster, if no packet loss occurs. The performance parameters provided by input and output measurement points of the identified cluster are then used for providing the performance measurements.

  • Patent number: 10812632
    Abstract: A system includes network interface controller (NIC) and a host processor. The host processor may run a hypervisor or OS which may manage virtual network activity for virtual machines (VMs) and/or applications. The NIC may provide a physical function to the hypervisor to support network activity by the VMs and/or applications. Some VMs and/or applications on the network may bypass the hypervisor and access virtual functions from the NIC. The NIC may execute a configurable flow analyzer (CFA), which may perform flow processing operations on the network traffic. The CFA may access flow configuration and management parameters maintained by the hypervisor to control implementation of the flow processing operations. Performing the flow processing operations on the traffic for the VMs and/or applications bypassing the hypervisor or OS may extend management by the hypervisor or OS to these VMs and/or applications.
