Here’s a simplified example of how network slicing might be configured using a hypothetical SDN controller API:

import requests
import json

# SDN Controller API endpoint
API_ENDPOINT = "https://sdn-controller.example.com/api/v1/network-slices"

# Define a network slice for a low-latency application
low_latency_slice = {
    "name": "LowLatencySlice",
    "description": "Network slice for ultra-low latency applications",
    "qos_parameters": {
        "latency": "1ms",
        "bandwidth": "1Gbps",
        "reliability": "99.999%"
    },
    "isolation_level": "high",
    "resource_allocation": {
        "cpu": "4",
        "memory": "8GB",
        "storage": "100GB"
    }
}

# Create the network slice
response = requests.post(
    API_ENDPOINT,
    data=json.dumps(low_latency_slice),
    headers={"Content-Type": "application/json"}
)

if response.status_code == 201:
    print("Network slice created successfully")
    print("Slice ID:", response.json()["slice_id"])
else:
    print("Failed to create network slice")
    print("Error:", response.text)

This example demonstrates a basic approach to programmatically creating a network slice for a low-latency application. In a real-world scenario, the configuration would be more complex and would need to integrate with the specific SDN and NFV platforms in use.
