cb-network v0.0.4 for Café Mocha release

The cb-network's overall structure and control mechanism have been improved. The big changes included in this release are essential for cb-network to move towards supporting adaptiveness, fault-tolerance, lightweightness, and ease of use.

Feature

• Major structural change of cb-network to the event-driven architecture
• Update configuration and control mechanisms of both cb-network server (controller) and agent for the followings:
  • Operate multiple Cloud Adaptive Networks (CLADNets)
  • Manage the overall CLADNet information on the distributed key-value store
  • Support concurrency
• Improve AdminWeb for the followings:
  • Support multiple Cloud Adaptive Networks (CLADNets)
  • Create the desired CLADNet CIDR block by the user
  • Check CLADNet connectivity and latency
• Add scripts to build and run agent for easy deployment
• Containerize cb-network server (controller)

Test

Prerequisites

• A distributed key-value store cluster is running
• The cb-network server (controller) is running

Tested with

• CB-Tumblebug v0.3.12
• CB-Spider v0.3.19

Test environment

NOTE - 1 VM is deployed in each region.

Cloud Service Provider (CSP) - Region pairs:

• Amazon Web Services (AWS) - Sydney, Australia
• Alibaba Cloud - Tokyo, Japan
• Google Cloud Platform (GCP) - Changhua County, Taiwan
• Microsoft (MS) Azure - California, United States

Note

• Use Golang v1.16
• Use Ubuntu 18.04 LTS (AWS, GCP, Alibaba Cloud) or 20.04 LTS (MS Azure)

Test scenario

• Create an MCIS (a logical group of VMs) by CB-Tumblebug API (Of course, CB-Spider is used.)
• Install and run the cb-network agent to the MCIS for configuring a CLADNet by CB-Tumblebug API
• Check if the CLADNet is successfully configured and running by Weave Scope
