International Classification:

H04L 12/26
H04L 12/851
H04L 9/08

Abstract:

A method for network flow metadata processing at a network packet broker includes, receiving, as input at the network packet broker, network flow metadata, the network flow metadata including a network flow statistic generated by a network device regarding packets in the network flow. The method further includes accessing, by the network packet broker, a network flow metadata processing rules database and identifying a network flow metadata processing rule to apply to the network flow metadata. The method further includes processing, by the network packet broker, the network flow metadata using the network flow metadata processing rule. The method further includes forwarding, by the network packet broker and based on results of the processing, egress network flow metadata to a network tool.

Abstract:

Systems and methods are disclosed for drop detection and protection with respect to packet monitoring in virtual processing environments. Tap agents monitor and capture packets from the network traffic associated with network applications running within these virtual processing environments. Sequence numbers are added in packet encapsulation before tap packets are forwarded to tool agents. The tool agents then use the sequence numbers to detect packet drops within the tap packets. After drop detection, the tool agents send drop detection messages to an agent controller, and the agent controller generates and sends reconfiguration messages to the tap agents based upon the drop detection messages. The tool agents can also send drop detection messages directly to the tap agents. The tap agents adjust their operations based upon the reconfiguration messages and/or the drop detection messages to reduce packet drops within subsequent tap packets communications.
