METHODS AND APPARATUS FOR DETECTION OF A NAT DEVICE

摘要

A method for detection of a network address translation (NAT) device in a network is described herein. An edge network device detects a first packet at an edge port of the edge network device. A second packet is detected at the edge port of the edge network device. It is determined whether a time to live (TTL) value associated with the first packet is different from a TTL value associated with the second packet. Where the TTL value associated with the first packet is different from a TTL value associated with the second packet, it is determined that a NAT device is connected to the edge port. Where the TTL value associated with the first packet is the same as a TTL value associated with the second packet, it is determined that a NAT device is not connected to the edge port.
