emu-vim

Requirements

• needs the latest Dockernet to be installed in the system
• the wrapper uses standard Python imports to use the Dockernet modules
• Uses ZeroMQ based RPC to open a cloud-like interface that can be used by a demo CLI client
• pip install import zerorpc
• This will be replaced / extended by a REST API later

Project structure

• emuvim/ all emulator code
• api/ Data center API endpoint implementations (zerorpc, OpenStack REST, ...)
• cli/ CLI client to interact with a running emulator
• dcemulator/ Dockernet wrapper that introduces the notion of data centers and API endpoints
• test/ Unit tests
• example_topology.py An example topology script to show how topologies can be specified

Run

• First terminal:
• sudo python example_topology.py
• Second terminal:
• TODO add CLI commands here (e.g. request the start of a new compute resource)

TODO

• DCemulator
• ...
• Cloud-like reference API with CLI for demonstrations
• Write CLI client
• Start compute
• Stop compute
• Re-factor endpoint API so that API objects can be more or less statless (ask DCEmulator for available DCs instead of maintaining a own list)
• Create an Ansible-based automatic installation routine
• Add resource constraints to datacenters
• Check if we can use the Mininet GUI to visualize our DCs?

Features

• Define a topology (Python script)
• Add data centers
• Add switches and links between the,
• Define API endpoints in topology
• call startAPI from topology definition and start it in a own thread
• make it possible to start different API endpoints for different DCs
• DCemulator
• correctly start and connect new compute resources at runtime
• remove and disconnect compute resources at runtime
• do IP management for new containers
• list active compute resources
