TROUBLESHOOTING MECHANISM FOR TRACKING PACKAGES ON NETWORK FUNCTION VIRTUALIZATION PLATFORM

摘要

new troubleshooting mechanism for packet tracking in a network role virtualization platform, which aims to identify the defective virtual network function for diagnosing problems in data packet forwarding in network function virtualization environments. network function virtualization? nfv), where a single server is capable of running thousands of instances of virtual functions to simplify problem detection in internal packet processing from a centralized user interface to trace management and configuration. Using the nfv platform's traffic classifier module, the engine assesses once if the transmitted data packet matches any configured tracking criteria, combining packet tracking in service chain processing and a centralized interface for managing and configure traces based on user information, service packs, and traffic profiles. The troubleshooting mechanism presented here is the tracking of packets throughout the service chain, allowing the identification of all functions that received, processed and sent a particular set of packets. trace criteria processing is performed at the time of packet classification, which occurs when the packet enters the platform, reducing the processing load of virtualized functions that do not need to re-evaluate packets against configured trace criteria.
