| Hybrid Two-Step Performance Measurement Method | ||||||||||||||
|
The development and advancements in network operation automation have brought new measurement methodology requirements. Among them is the ability to collect instant network operational state as the packet being processed by the networking elements along its path through the domain. That task can be solved using on-path telemetry, also called hybrid measurement. An on-path telemetry method allows the collection of essential information that reflects the operational state and network performance experienced by the packet. This document introduces a method complementary to on-path telemetry that causes the generation of network telemetry information. This method, referred to as Hybrid Two-Step (HTS), separates the act of measuring and/or calculating the performance metric from collecting and transporting network operational state. The HTS packet traverses the same set of nodes and links as the trigger packet, thus simplifying the correlation of informational elements originating on nodes traversed by the trigger packet. | |||||||||||||
| Bootstrapping Remote Secure Key Infrastructure (BRSKI) Cloud Registrar | ||||||||||||||
|
Bootstrapping Remote Secure Key Infrastructures (BRSKI) defines how to onboard a device securely into an operator-maintained infrastructure. It assumes that there is local network infrastructure for the device to discover. On networks without that, there is nothing present to help onboard the device. This document extends BRSKI and defines behavior for bootstrapping devices for deployments where no local infrastructure is available, such as in a home or remote office. This document defines how the device can use a well-defined "call-home" mechanism to find the operator-maintained infrastructure. This document defines how to contact a well-known Cloud Registrar, and two ways in which the device may be redirected towards the operator-maintained infrastructure. The Cloud Registrar enables discovery of the operator-maintained infrastructure, and may enable establishment of trust with operator-maintained infrastructure that does not support BRSKI mechanisms. This document updates RFC 8995 (BRSKI). | |||||||||||||
