The granted patent US12074854B1 describes a system and method for evaluating the performance of services provided by servers through the use of a probe. The probe is equipped with one or more processors that receive a start beacon packet, which initiates a test of the service. Following this, the probe identifies a series of encrypted data packets exchanged between a client device and the servers. The system is designed to determine the key information necessary for decrypting these packets, allowing the probe to log at least one of the packets for further evaluation. The logging process is initiated upon receipt of the start beacon packet, and the probe can also receive a stop beacon packet to indicate the end of the test, preventing any additional data packets from being logged thereafter.

Additionally, the patent outlines various functionalities of the probe, including the ability to receive key information from the client device and to decrypt the logged packets using this information. The system supports security protocols such as Transport Layer Security (TLS) or QUIC for encrypting the data packets. The probe can parse the headers of the data packets to verify source IP addresses and ensure that the logged packets correspond to the initial test parameters. The patent also includes provisions for storing both encrypted and decrypted data packets in the log, facilitating a comprehensive analysis of the service's performance based on the captured data.
