Cloud-Based Network Tool Optimizers For Server Cloud Networks

摘要

Network tool optimizers for server cloud networks and related methods are disclosed. In part, master filters are defined to segregate and control user traffic, and user filters are defined to forward the user traffic to cloud-based network tools or tool instances. A master user interface and user interfaces for each user are provided so that the master filters and user filters can be defined and managed. A filter rules compiler within the cloud-based network tool optimizer then combines the master filters with the user filters, resolves conflicts in favor of the master filters, and generates filter engine rules that are applied to filter engines within the network tool optimizer for the cloud network. The filter engines then forward packets received at input ports for the network tool optimizer to output ports for the network tool optimizer that are coupled to network tools or tool instances within the cloud network.

主权项

1. A method to control packet traffic for multiple users of cloud resources within a cloud network, comprising:
allowing, through a master user interface, configuration of one or more master filters to determine how packets received from one or more packet sources are forwarded to a plurality of virtual ports, each virtual port being associated with a different user of cloud resources within a cloud network; allowing, through one or more user interfaces, configuration of a plurality of sets of one or more user filters, each set of one or more user filters being associated with a different user of cloud resources within the cloud network and determining how packets from a virtual port associated with that user are forwarded from the plurality of virtual ports to one or more packet destinations; generating filter rules based upon the one or more master filters and the plurality of sets of one or more user filters with conflicts between the master filters and user filters being resolved in favor of the master filters; receiving packets from the one or more packet sources; and forwarding the received packets to the one or more packet destinations based upon the filter rules so that packet traffic for each user is forwarded based at least in part upon the set of one or more user filters for that user; wherein the master user interface displays filter information only for master filters between the one or more packet sources and the plurality of virtual ports, and wherein the one or more user interfaces display filter information only for user filters between the plurality of virtual ports and the one or more packet destinations; and wherein the one or more user interfaces comprise a separate user interface for each user.
