METHODS AND SYSTEMS FOR CLASSIFYING TRAFFIC FLOWS BASED ON PACKET PROCESSING METADATA
Methods and system for directing traffic flows to a fast data path or a slow data path are disclosed. Parsers can produce packet header vectors (PHVs) for use in match-action units. The PHVs are also used to generate feature vectors for the traffic flows. A flow training engine produces a classification model. Feature vectors input to the classification model result in output predictions predicting if a traffic flow will be long lived or short lived. The classification models are used by network appliances to install traffic flows into fast data paths or the slow data paths based on the predictions.
Switch with network services packet processing by service software instances
Virtual machine environments are provided in the switches that form a network, with the virtual machines executing network services previously performed by dedicated appliances. The virtual machines can be executed on a single multi-core processor in combination with normal switch functions or on dedicated services processor boards. Packet processors analyze incoming packets and add a services tag containing services entries to any packets. Each switch reviews the services tag and performs any network services resident on that switch. This allows services to be deployed at the optimal locations in the network. The network services may be deployed by use of drag and drop operations. A topology view is presented, along with network services that may be deployed. Services may be selected and dragged to a single switch or multiple switches. The management tool deploys the network services software, with virtual machines being instantiated on the switches as needed.
