First Claim
Patent Images
1. A method comprising:
- under control of one or more processors,transmitting a data packet to a destination node, the data packet comprising information of a specific node or path that the data packet is to be routed through; and
determining a health condition of the specific node or path based at least in part on a result of the transmitting of the data packet.

Abstract
In some cases, a network monitoring system may determine an operating or health condition of a node or connection link in a network (e.g., a datacenter network) by preparing an encapsulated data packet according to a tunneling protocol. Depending on a result of routing the encapsulated data packet, the network monitoring system determines whether the node or connection link is functioning normally or is experiencing an issue such as overloading or malfunctioning.

11. One or more computer-readable media storing executable instructions that, when executed by one or more processors, cause the one or more processors to perform acts comprising:
-
determining one or more specific nodes or paths of which operation conditions are to be analyzed; and iteratively encapsulating one or more respective data packets corresponding to the one or more specific nodes or paths to form a test data packet. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A system comprising:
-
one or more processors; memory storing executable instructions that, when executed by the one or more processors, cause the one or more processors to perform acts comprising; including a first data packet within a second data packet, a packet header of the second data packet comprising information associated with a specific node of which operating condition is to be determined and a packet header of the first data packet comprising information associated with a destination node that determines the operating condition of the specific node; and sending out the second data packet. - View Dependent Claims (19, 20)
