MUMBAI, India, June 24 -- Intellectual Property India has published a patent application (202441098112 A) filed by Hewlett Packard Enterprise Development Lp on December 11, 2024, for Efficient Internal Latency Measurement In Network Devices.
Inventor includes Venkatavaradhan Devarajan.
The application for the patent was published on June 12, 2026, under issue no. 24/2026.
Abstract: In a network, a network device can receive, at the forwarding hardware of the network device from a processor of the network device, a packet with an indicator indicating the packet to be a delay measurement packet via a processor port of the processor. The network device can tag, using the forwarding hardware, the packet with a first timestamp indicating a time when the forwarding hardware receives the packet. The network device can then forward, using the forwarding hardware, the packet to an egress queue of an egress network port of the network device. The network device can retrieve, using the forwarding hardware, the packet from the egress queue and tag the packet with a second timestamp indicating a time when the forwarding hardware retrieves the packet for forwarding. The network device can include, using the forwarding hardware, a delay indicated by the first and second timestamps into the packet.
