Method and system for collecting topology information
First Claim
1. A method comprising:
- identifying, by a sensor, a topology trace packet;
modifying, by the sensor, a payload of the topology trace packet to include a sensor identifier, of the sensor, without modifying a header of the topology trace packet; and
sending, by the sensor and after modifying the payload of the topology trace packet, the topology trace packet in a direction of a node identified by a destination address of the topology trace packet.

Abstract
A method of providing topology information about a network to a topology manager is disclosed. The network includes a plurality of sensors each having a sensor ID, and the method includes performing the following steps at each of the plurality of sensors: receiving a stream of packets and identifying a topology trace packet in the stream of packets, wherein the topology trace packet has a destination address and an ID of a previous sensor, including the sensor ID in the topology trace packet, sending the topology trace packet to the destination address, forming a report message so as to include the sensor ID, the previous sensor ID, sending the report to the topology manager; and, providing network addresses of adjacent nodes to the topology manager.

16. A non-transitory computer-readable medium storing instructions, the instructions comprising:
one or more instructions that, when executed by a sensor, cause the sensor to; identify a topology trace packet; modify, to obtain a modified topology trace packet, a payload of the topology trace packet to include a sensor identifier, of the sensor, without modifying a header of the topology trace packet; and send the modified topology trace packet in a direction of a node identified by a destination address of the modified topology trace packet. - View Dependent Claims (17, 18, 19, 20, 21)
