ONE WAY DELAY MEASUREMENT METHOD FOR COMPUTER NETWORKS

摘要

THE PRESENT INVENTION DISCLOSES A METHOD FOR ACCURATELY MEASURING ONE WAY DELAY IN A COMPUTER NETWORK COMPRISING THE STEPS OF PROVIDING A CRYPTOGRAPHIC PROTOCOL TO SECURE THE COMMUNICATION BETWEEN INTERNET CONTROL MESSAGE PROTOCOL (ICMP) TIMESTAMP REQUEST PACKETS OF A CLIENT DEVICE AND INTERNET CONTROL MESSAGE PROTOCOL (ICMP) TIMESTAMP REPLY PACKETS OF A DEVICE SYSTEM, THEREBY PREVENTING A POTENTIAL INTRUDER FROM USING THESE INTERNET CONTROL MESSAGE PROTOCOL (ICMP) TIMESTAMP PACKETS TO OVERCOME THE TIME-BASED AUTHENTICATION PROTOCOL IN THE NETWORK.
