(c) Cisco Systems, Inc - - -Introduction ------------- - -NFVbench can be decomposed in the following components: -- Configuration -- Orchestration: - - - Staging - - Traffic generation - - Results analysis - -Configuration -------------- -This component is in charge of getting the configuration options from the user and consolidate them with -the default configuration into a running configuration. - -default configuration + user configuration options = running configuration - -User configuration can come from: -- CLI configuration shortcut arguments (e.g --frame-size) -- CLI configuration file (--config [file]) -- CLI configuration string (--config [string]) -- REST request body -- custom platform pluging - -The precedence order for configuration is (from highest precedence to lowest precedence) -- CLI configuration or REST configuration -- custom platform plugin -- default configuration - -The custom platform plugin is an optional python class that can be used to override default configuration options -with default platform options which can be either hardcoded or calculated at runtime from platform specific sources -(such as platform deployment configuration files). -A custom platform plugin class is a child of the parent class nfvbench.config_plugin.ConfigPlugin. - -Orchestration -------------- -Once the configuration is settled, benchmark orchestration is managed by the ChainRunner class (nfvbench.chain_runner.ChainRunner). -The chain runner will take care of orchestrating the staging, traffic generation and results analysis. - - -Staging -------- -The staging component is in charge of staging the OpenStack resources that are used for the requested packet path. -For example, for a PVP packet path, this module will create 2 Neutron networks and one VM instance connected to these 2 networks. -Multi-chaining and VM placement is also handled by this module. - -Main class: nfvbench.chaining.ChainManager - -Traffic Generation ------------------- -The traffic generation component is in charge of contrilling the TRex traffic generator using its python API. -It includes tasks such as: -- traffic check end to end to make sure the packet path is clear in both directions before starting a benchmark -- programming the TRex traffic flows based on requested parameters -- fixed rate control -- NDR/PDR binary search - -Main class: nfvbench.traffic_client.TrafficClient - - -Traffic Generator Results Analysis ----------------------------------- -At the end of a traffic generation session, this component collects the results from TRex and packages them in a format that -is suitable for the various output formats (JSON, REST, file, fluentd). -In the case of multi-chaining, it handles aggregation of results across chains. - -Main class: nfvbench.stats_manager.StatsManager |
