Techniques to facilitate verification of in-situ network telemetry data of data packet of data traffic of packet-switched networks are described herein. A technique described herein includes a network node obtaining a data packet of data traffic of a packet-switched network. The data packet includes an in-situ network telemetry block. The network node obtains telemetry data and cryptographic key. The cryptographic key confidentially identifies the network node. The node encrypts at least a portion of the telemetry data based on the cryptographic key to produce signed telemetry data and updates telemetry-data entry of the in-situ network telemetry block. The telemetry data and signed telemetry data is inserted into the telemetry-data entry. The node forwards the data packet with the updated telemetry-data entry to another network node of the packet-switched network.

Verification of in-situ network telemetry data in a packet-switched network

A die-to-die repeater circuit includes a transmit circuit coupled to a die-to-die interconnect, the transmit circuit including at least one flip flop to function as a part of a linear feedback shift register (LFSR) to transmit a value across the die-to-die interconnect for design for test (DFT) to check proper operation of the die-to-die interconnect, and a receive circuit coupled to the die-to-die interconnect, the receive circuit including at least one flip flop to function as part of a multiple input shift register (MISR).

In one embodiment, a service configured to execute on trusted participant devices authenticates network service devices each having identifying information and one or more offered services, and creates an entry into a secure digital ledger for each authenticated network service device and associated offered services, each entry based on the identifying information and the one or more offered services for a corresponding network service device. Upon receiving an advertisement for an advertised service from an advertising device attached to a given trusted participant device, the service then requests and may receive an authentic ledger entry from the secure digital ledger for the advertised service. In response to either validating or failing to validate authenticity of the advertised service based on the authentic ledger entry, registration at the given trusted participant device of the advertised service for the received advertisement from the advertising device may either be permitted or denied, respectively.

Authenticated service discovery using a secure ledger

In one embodiment, a sleep proxy device identifies one or more services offered by a first node in the network. The sleep proxy device announces the one or more identified services to a second node in the network on behalf of the first node. The sleep proxy device intercepts an attempt by the second node to use the one or more services offered by the first node. The sleep proxy device causes the first node to switch from a low power state to an awake state, based on the intercepted attempt.
