Looks like youve clipped this slide to already. NETCONF vs RESTCONF NETCONF is a protocol defined by the IETF to address some of the challenges with CLI scripting by providing a standards-based method to "install, manipulate, and delete the configuration of network devices". /Parent /Catalog /S With the NETCONF capabilities in mind, the natural service automation flow is the NETCONF operation (on the running data store), editing the configuration in the candidate configuration datastore, validate the configuration, then the commit operation (to apply the configuration in the candidate datastore to the running data store), and finally the unlock operation. 405 /MediaBox R /S NETCONF uses XML as data format to exchange data. /Transparency . R RESTCONF achieves this by implementing a subset of the interaction [ Thanks for contributing an answer to Stack Overflow! NETCONF has the concept of datastores: candidate (working copy to manipulate with no impact on the current configuration, for prevalidate), running (complete and active configuration), startup (configuration loaded by the device at startup). Standards for pulling and pushing configurations from/to devices are desirable. In order to achieve this goal . network-programming; grpc; router; ietf-restconf; netconf; Brema. The all is the equivalent of NETCONF . It is required to be able to fetch separately configuration data, operational state data, and statistics from devices, and to be able to compare these between devices. Two of them are text-based, the third one (Protocol Buffers) is binary encoding not unlike ASN.1 BER used by SNMP. RESTCONF, specified by the IETF [RFC8040], specifies an HTTP-based protocol that provides a programmatic interface for accessing data defined in YANG, using the datastore concepts defined in the Network Configuration Protocol (NETCONF). In the world of data model-driven management, what is important is the set of YANG data modules from which APIs are deduced. << And if the existing tool chain (for example, storage and compute) is centered around HTTP, the RESTCONF option might be best one.

NETCONF permits the operator to specify the target datastore for an operation typically only 3 datastores are provided (startup, running and candidate), however the copy-config command may use a URL as the source or target if the NETCONF server implements the :url capability.

Starting in Junos OS Release 20.3, you can configure multiple outbound HTTPS clients, and you can . And finally, operators can access the orchestrator north-bound interface to manage their services (based on the service delivery YANG modules). 3 What this means is that RESTCONF interactions are one-and-done. 0 NETCONF defines configuration datastores and a set of Create, Read, Update, Delete (CRUD) operations that can be used to access these datastores. 19 As such, it is a requirement to support both data-oriented and task-oriented access control.
