Network Virtualization Operations Using a Scalable Statistics Collection Framework

摘要

Some embodiments provide a scalable framework to retrieve statistics relating different aggregated entities. In some embodiments, the aggregated entity is a pair of ports. The pair of ports can be physical ports of one or more physical forwarding elements. The pair of ports can be logical ports of one or more logical forwarding elements. In some embodiments, the aggregated entity is a machine or a group of machines. In some embodiments, the aggregated entity is an access control list (ACL).

主权项

1. A network comprising:
at least one forwarding elements to process packets for a set of one or more machines, wherein the forwarding element comprises a flow stats exporter to export flow statistics of each flow that is tagged with a tag that identifies a machine in the set of machines; and a network manager having an aggregator to receive the statistics from one or more flow stats exporters and aggregate the statistics in order to provide a total statistics relating to the set of machines.
