Code Example: Simulating 5G Network Slicing

To illustrate the concept of network slicing, here’s a simple Python script that simulates the allocation of network resources across different slices:

import random

class NetworkSlice:
    def __init__(self, name, bandwidth, latency):
        self.name = name
        self.bandwidth = bandwidth
        self.latency = latency

class FiveGNetwork:
    def __init__(self, total_bandwidth):
        self.total_bandwidth = total_bandwidth
        self.slices = []

    def create_slice(self, name, bandwidth_percentage, latency):
        bandwidth = self.total_bandwidth * (bandwidth_percentage / 100)
        slice = NetworkSlice(name, bandwidth, latency)
        self.slices.append(slice)

    def simulate_traffic(self):
        for slice in self.slices:
            usage = random.uniform(0.5, 1) * slice.bandwidth
            print(f"{slice.name}: Using {usage:.2f} Gbps with {slice.latency}ms latency")

# Create a 5G network with 100 Gbps total bandwidth
network = FiveGNetwork(100)

# Create network slices
network.create_slice("eMBB", 60, 10)  # 60% bandwidth, 10ms latency
network.create_slice("URLLC", 20, 1)  # 20% bandwidth, 1ms latency
network.create_slice("mMTC", 20, 50)  # 20% bandwidth, 50ms latency

# Simulate network traffic
print("Simulating 5G network traffic:")
network.simulate_traffic()

This script demonstrates how network resources can be allocated to different slices, each with its own bandwidth and latency characteristics. Running this simulation multiple times would show how traffic varies across the slices while respecting the allocated resources.
