Mediation Collection features

[NSPF-290198] Implement Telemetry for cloud native - Phase 2

Release introduced: 23.11

Cloud-native Telemetry (CN TLM) is introduced for the collection of statistics for devices supporting the gRPC/gNMI protocol. CN TLM micro services enhance collection performance and scalability while allowing MDM to focus its resources on mediation tasks. Note that in this release MDM will continue to support the collection of SNMP statistics for multi-vendor devices and the collection of accounting statistics.

[NSPF-272671] OAM GUI App Enhancements 23.11

Release introduced: 23.11

Feature description

This feature improves the GUI by:

automating filtering GUI operations
handling non-nodal OAM results

Customer benefits

These enhancements enhance the usability and visualizing test and test-suite results.

[NSPF-184018] RESTCONF: Search Enhancements (Paging)

Release introduced: 23.11

Feature Description

This feature incorporates paging functionality in Model Device Configurator (MDC) API, which allows users to handle large data sets by specifying the number of items per page and utilizing pagination parameters.

Customer Benefit

Paging functionality improves performance and reduces bandwidth usage when working with large datasets, as only the requested subset of data is retrieved. Moreover, it improves GUI navigation.

[NSPF-271841] [MDM-OAM] OAM API to retrieve all test results given a test type

Release introduced: 23.11

Feature Description

This feature focuses on developing a RESTConf call to enable the retrieval of OAM test results for a particular test type. The API not only allows specifying the test type (e.g. OAM-PM DMM), but also applying filters such as time range and fields.

Customer Benefit

The API/RESTConf call streamlines the process of retrieving test results by providing a convenient and efficient method. Users no longer need to manually search through all the OAM tests. Users have the flexibility to apply various filters to refine their search for test results. They can specify a specific test type, define a time range, and select specific fields of interest. This level of customization allows users to retrieve only the relevant data, eliminating the need to sift through irrelevant or redundant information.

[NSPF-262067] [MDM-OAM] Multi-vendor TWAMP Light - Test Adaptor

Release introduced: 23.11

Feature Description

Two-Way Active Measurement Protocol (TWAMP) provides a standards-based method for measuring the IP performance (packet loss, delay, and jitter) between two devices. TWAMP Light is an optional model included in the TWAMP standard. TWAMP Light uses the standard TWAMP packet format but provides a lightweight approach to gathering ongoing IP delay, jitter and synthetic loss performance data.

Customer Benefit

The feature enables vendor-agnostic TWAMP Light from NSP. This feature provides a generic TWAMP Light model, which is the basis for developing TWAMP Light adaptors for third-party devices. MV support requires the development of adaptors to support this capability. Review support in the target vendor and family.

[NSPF-267421] Modeled Device Configurator: RESTCONF support for with-defaults query params ('report-all' & 'explicit')

Release introduced: 23.4

Feature Description

RESTCONF protocol supports two query parameters called 'report-all' and 'explicit' for handling the default values of the data nodes as described in RFC 8040, the behavior of each query is:

When 'report-all' is used, the information in the response includes all the values, regardless of whether the values are the same as the default values or not.
When 'explicit' is used, the information that has non-default values is included in the response.

Customer Benefit

These query parameters can be used with GET and GET-config methods to retrieve data resources from network devices via Model Device Configuration using RESTCONF protocol. By using these query parameters, the client can choose how to handle default values and get a more accurate representation of the data resources on the device.

Moreover, this feature is used by NSP applications to improve their efficiency by using 'report-all' and 'explicit' to obtain the required parameters.

[NSPF-262021] NSP YANG Framework Extensions: Improvements in the support of WHEN clause

Release introduced: 23.4

Feature Description

Yet Another Next Generation (YANG) is a data modelling language for the definition of data sent over network management protocols such as the NETCONF and RESTCONF.

YANG provides statements in RFC 6020 to model the data used for network management.

Customer Benefit

The feature enables the support for when statements. The "when" statement makes its parent data definition statement conditional. The node defined by the parent data definition statement is only valid when the condition specified by the "when" statement is satisfied.

Use subject to agreed restrictions on disclosure and use.
