process_migration

Example: Process migration

This is the simplest initial version of the system. The hosts are run in separate network namespaces, and connected to the switch via virtual ethernet (veth) pairs.

Running the example

To build the topology, start containers and run the controller, run:

make

To run a xterm session in each network namespace, run:

make terminals

In hosts h2 and h3, run:

./server.sh

to start the server.

In host h1, run:

./client.sh

to start the client.

To migrate a process from the source host to the target host, and update the switch accordingly, run:

make migrate SOURCE=<> TARGET=<>

To cleanup the topology, networks, pods, and containers, run:

make clean

To show logs of e.g. the s1 switch, run:

tail -f ../../load_balancer/logs/s1.log
