AtlanticWave-SDX 2.0 Release Notes | ||
================================== | ||
|
||
.. todo:: Write this. | ||
Overview | ||
-------- | ||
|
||
The AtlanticWave-SDX 2.0 project achieves its goals by providing a | ||
standardized interface (SDX-LC) between the SDX Controller and different | ||
OXPOs. This abstraction layer enables the SDX Controller to communicate | ||
with various OXPOs using a consistent data model, regardless of the API | ||
variations in other solutions. | ||
|
||
Software Releases | ||
----------------- | ||
|
||
Sources of SDX Controller, SDX-LC, and the libraries they use (pce and | ||
datamodel) are available at GitHub: | ||
|
||
- https://github.com/atlanticwave-sdx/sdx-controller/releases/tag/2.0.0 | ||
- https://github.com/atlanticwave-sdx/sdx-lc/releases/tag/2.0.0 | ||
- https://github.com/atlanticwave-sdx/pce/releases/tag/2.0.0 | ||
- https://github.com/atlanticwave-sdx/datamodel/releases/tag/2.0.0 | ||
|
||
Docker images are available too:: | ||
|
||
$ docker pull awsdx/sdx-lc:2.0.0 | ||
$ docker pull awsdx/sdx-controller:2.0.0 | ||
|
||
Components | ||
---------- | ||
|
||
- Open eXchange Points (OXPs): Open eXchange Points (OXPs) facilitate | ||
data exchange between networks. | ||
|
||
- Each OXP consists of two essential elements: | ||
|
||
+ Network Orchestrator (OXPO): Automated network configuration, | ||
flow, and traffic engineering policies. | ||
|
||
+ SDX Local Controller (SDX-LC): Acts as a bridge between the OXPO | ||
and the centralized SDX Controller. | ||
|
||
OXPO Selection | ||
-------------- | ||
|
||
- Each OXP's network operation team independently defines and manages | ||
its OXPO. | ||
|
||
- Different OXPOs are integrated into the AtlanticWave-SDX ecosystem. | ||
|
||
- AmLight Open Exchange Point (OXP) leverages the Kytos-ng | ||
Software-Defined Networking (SDN) platform. | ||
|
||
- SAX OXP deploys OESS 2.0 for network orchestration, not included in | ||
this release. | ||
|
||
Inter-Domain Provisioning | ||
------------------------- | ||
|
||
- OXPs open their interfaces to accept provisioning requests and | ||
export topology updates. | ||
|
||
- SDX-LC uses each OXPO's API to retrieve topological information and | ||
push provisioning requests. | ||
|
||
SDX-LC Functionality | ||
-------------------- | ||
|
||
The SDX-LC module facilitates the translation of instructions from the | ||
data model of the centralized SDX Controller to the API of each OXPO. It | ||
simplifies the communication process and ensures compatibility with | ||
existing APIs. | ||
|
||
OXPO API Variations | ||
------------------- | ||
|
||
- Different OXPOs may have variations in their interfaces. | ||
|
||
- Kytos-ng provide APIs for exporting topological data and receiving | ||
service provisioning requests. | ||
|
||
System Design | ||
------------- | ||
|
||
- The system design integrates Kytos-ng OXPOs with SDX-LC. | ||
|
||
- Three approaches are considered for gathering topology data | ||
depending on OXPO support for the AW-SDX 2.0 Topology Data Model | ||
specification. First approach is part of this release: | ||
|
||
- The OXPO supports the AW-SDX 2.0 Topology Data Model specification | ||
and pushes the topology data to the SDX-LC OpenAPI interface | ||
|
||
Additional Elements in SDX Topology | ||
----------------------------------- | ||
|
||
The SDX topology includes elements such as Name, Id, Timestamp, and | ||
Version control for better management and versioning. | ||
|
||
MEICAN Integration | ||
------------------ | ||
|
||
- MEICAN web application offers support to create circuits. | ||
|
||
- It retrieves and maps topology information from the SDX-Controller | ||
endpoint. | ||
|
||
- ORCID/CI Login Authentication is introduced for users. | ||
|
||
- The framework supports adding user permissions based on roles. | ||
|
||
API Testing | ||
----------- | ||
|
||
- API testing ensures functional accuracy, security, performance, | ||
contract compliance, and system reliability. | ||
|
||
- Various types of tests, including unit tests, functional tests, | ||
integration tests, and end-to-end tests, are conducted to validate | ||
the system's behavior and functionality. | ||
|
||
GitHub Setup | ||
------------- | ||
|
||
- The GitHub repository "sdx-continuous-development" contains | ||
submodules for integrating components like Kytos-ng, OXPOs, SDX-LC, | ||
SDX Controller, and Meican. | ||
|
||
- The environment setup script configures the host machine with | ||
necessary tools. | ||
|
||
Building the Environment | ||
------------------------ | ||
|
||
Commands are provided to build the Kytos-ng components, OXPOs, and | ||
MongoDB container. | ||
|
||
Applying Patches | ||
---------------- | ||
|
||
The repository may require patches for specific configurations or bug | ||
fixes. | ||
|
||
Running the Integration | ||
----------------------- | ||
|
||
- Docker Compose is used to orchestrate the system, running containers | ||
for Kytos-ng, SDX-LC, MongoDB, Mininet, and RabbitMQ. | ||
|
||
- These release notes provide an overview of the AtlanticWave-SDX 2.0 | ||
project, its components, system design, and testing procedures. | ||
They highlight the integration of various OXPOs, Meican, and the | ||
importance of API testing for system reliability and | ||
functionality. The GitHub setup and environment building steps are | ||
also detailed. | ||
