P4Mite

P4mite - resource aware load balancer

Overview

There are multiple folders in the project:

1. The switches
2. The application
3. SmartNIC-LB

Switches

There are three switches implemented:

cd switches

To bring P4Mite switch up

./setup_switch.sh p4mite_switch.p4

To bring ECMP switch up

./setup_switch.sh ecmp_switch.p4

To bring round robin switch up

./setup_switch.sh round_robin.p4

For each switch, there is a Python script containing the configurations. The configuration files should be updated based on the physical connections and IP addresses in the testbed. In our case:

• The client: 10.50.0.1
• The server: 10.50.0.6
• The SmartNIC: 10.50.0.16

Applications

There are 5 ones in the applications folder:

1. p4mite_agent.py: The agent monitoring server and measure latency using tcpdump

cd applications
sudo tcpdump --immediate-mode -n -i <INTERFACE_NAME> | sudo python3 p4mite_agent.py <SERVER_ADDR> <ACCELERATE_ADDR> <THRESHOLD>

2. Microbenchmark: a synthetic workload

To run the microbenchmark's server

cd applications/microbenchmark/server

# To see the options
python3 server_bite_report.py -h

# An example:
python3 server_bite_report.py -H <HOST_ADDR> -P <PORT>

# Run multiple instances:
./run.sh

To run the client:

cd applications/microbenchmark/client

# To see the options
python3 client_multi_port.py -h

#By defaults the client sends the request to ports [10001,10020] of the server.
# An example:
python3 client_multi_port.py -H <HOST_ADDR> -N <NUMBER_OF_REQUESTS> -R <SENDING_RATE>

3. VGG16:

there are two version of the server for VGG16. One version uses TensorFlow (server_udp_reporting.py), and the other version uses TensorFlow lite (server_udp_arm.py).

cd applications/vgg16/server

# To run TensorFlow version
python3 server_udp_reporting.py -H <HOST_ADDR> -P <PORT>

# To run TensorFlow lite version
python3 server_udp_arm.py -H <HOST_ADDR> -P <PORT>

# To see help
python3 server_udp_reporting.py -h
python3 server_udp_arm.py -h

VGG16's client

cd applications/vgg16/client

#By defaults the client sends the request to ports [10001,10020] of the server.
python3 client_udp_multi_ports.py -H <HOST_ADDR> -N <NUMBER_OF_REQUESTS> -R <SENDING_RATE>

# To see help:
python3 client_udp_multi_ports.py -h

4. KNN:

KNN's Server:

cd applications/knn/server

python3 server_knn_reporting.py <HOST_ADDR> -P <PORT>
# To see help:
python3 server_knn_reporting.py -h

KNN's Client:

cd applications/knn/client

#By defaults the client sends the request to ports [10001,10020] of the server.
python3 client_udp_multi_ports.py -H <HOST_ADDR> -N <NUMBER_OF_REQUESTS> -R <SENDING_RATE>

# To see help:
python3 client_udp_multi_ports.py -h

5. DNS

DSN's Server:

cd applications/dns/server
python3 dns.py

DNS's client:

cd applications/dns/client
python dnsclient.py --server <SERVER_ADDR>:5053 -R <RATE> 'example.com'

SmartNIC-LB

cd SmartNIC-LB

sudo python3 lb.py -H <LB_ADDR or SmartNIC_ADDR> -P <PORT>

# To see the help:
python3 lb.py -h
