  • Network latency measurement and analysis system
    Patent number: 10735307
    Abstract: Deploying a point of presence (PoP) changes traffic flow to a cloud service provider. To determine if the PoP improves the performance of a cloud service to a client, actual network latencies between the client and the cloud service are measured. In more complex scenarios, multiple PoPs are used. The client sends multiple requests for the same content to the cloud provider. The requests are sent via different routes. The cloud provider serves the requests and collates the latency information. Based on the latency information, a route for a future request is selected, resources are allocated, or a user interface is presented. The process of determining the latency for content delivered by different routes may be repeated for content of different sizes. A future request is routed along the network path that provides the lowest latency for the data being requested.

  • Equal cost multiple path group failover for multicast
    Patent number: 10728173
    Abstract: A method of forwarding a multicast packet by a physical forwarding element is provided. The method receives a multicast packet that identifies a multicast group. The method scans a multicast tree associated with the multicast group to identify an ECMP group for forwarding the multicast packet to a member of the multicast group. The method calculates a group of hash values on several fields of the packet and uses a first hash value in the group of hash values to identify a first path in the ECMP. The method determines that the identified path has failed. The method uses a second hash value to identify a second path in the ECMP. The method forwards the multicast packet to the multicast member through the second path.
