v5.0 (2019-09-06)

New module: 5GTANO lightweight life cycle manager (LLCM)

The 5GTANGO LLCM module is an improved version of SONATA's dummy gatekeeper and allows to directly on-board and instantiate 5GTANGO network service packages in an emulated multi-PoP environment. Example 2 shows how to use this new module.

Documentation

• updated Example 1: Manually instantiate VNFs
• updated Example 2: Deploy 5GTANGO service package using 5GTANGO LLCM

Features

• CNF support in LLCM
• Multi VDU/CDU support in LLCM
• E-Tree network support in LLCM
• Integrated vim-emu with Containernet 3.0
• LLCM: Instance-specific env. vars
• LLCM: Custom static placement algorithm
• LLCM: Integrated with tng-cli
• LLCM: Multi-instance support
• LLCM: Port publishing
• Integration with Juju

Bugs fixed

• Glance fake API now works with latest glance and OpenStack clients
• CORS fix for status endpoint
• Improved REST performance
• Fixed chaining support
• Fixed glance fake API

v4.0 (2018-07-31)

This release removes the old project history from GitHub and replaces the master branch of son-emu with a mirror of the master branch of OSM's vim-emu projects. So son-emu is now fully aligned with vim-emu. However, this repository might contain 5GTANGO-specific code in future releases.

Changes since last release:

• Integrated vim-emu with OSM release FOUR
• Re-deploy network services without emulator retart
• Made complete codebase PEP8 compatibles
• Added automated code style checks to the CI pipeline
• Made port deletion process more robust
• Better unit tests
• Cleaned up examples
• Added examples for OSM release FOUR
• Many small bug fixes

v3.1

Minor bugfixes.

v3.0 (2017-09-01)

SONATA's Multi-PoP Emulation Platform

• Improved REST interface management
• Fixed: External dependencies to outdated libraries
• Fixed: VLAN range according to (802.1Q Standard 5.3.1)
• OpenStack-like API extensions
• New OpenStack Neutron-like chaining API
• Support for OpenStack Keystone v3.0 endpoints
• VNF stop script execution (dummy gatekeeper)
• Many minor bugs are fixed!

v2.1 (2017-05-22)

SONATA's Multi-PoP Emulation Platform (main)

• Emulator's dashboard is now automatically served by the REST API server
• Extended dashboard shows with placement graph, IP and MAC of each VNF interface and allows to start an xterm terminal window by double-clicking on the VNF node in the graph.
• REST API updates: export the placement graph in json format (3djs compatible), start a terminal window for a deployed VNF
• Auto-deploy and auto-update functionalities added to dummy gatekeeper endpoint
• Host-based service access points (SAPs)
• Auto-deploy service access points (SAPs)
• Finalized topology for son-profile active mode integration
• Automated volumes support for dummy gatekeeper deployments
• and last but not least: Plenty of bugfixes 👍

OpenStack-like API Endpoints added to SONATA Emulator

We added OpenStack-like API endpoints to son-emu/master. These API endpoints try to simulate the behavior of OpenStack-based VIM APIs and allow to start/stop and manage VNF containers in the attached emulated datacenter (PoP). This allows to use son-emu and its emulated VIMs/PoPs with existing orchestration solutions, like SONATA SP and OSM. These APIs are not a feature complete copy of the original OpenStack APIs but they offer enough functionality for basic SONATA SP and OSM integration.

Available API endpoints:

• Keystone: Endpoint management
• Nova: Start/stop compute instances (VNFs)
• Heat: Deploy (simple) HEAT templates on the emulator
• Glance: List available images (the Docker images available to the emulator). Read only.
• Neutron: Early prototype. Service function chaining support is still work in progress.
