Code Example: Simulating 5G Network Slicing

To illustrate the concept of network slicing in 5G, here’s a simple Python simulation:

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, latency):
        if sum(slice.bandwidth for slice in self.slices) + bandwidth <= self.total_bandwidth:
            new_slice = NetworkSlice(name, bandwidth, latency)
            self.slices.append(new_slice)
            print(f"Slice '{name}' created successfully.")
        else:
            print(f"Error: Not enough bandwidth to create slice '{name}'.")

    def simulate_traffic(self):
        for slice in self.slices:
            traffic = random.randint(0, slice.bandwidth)
            print(f"Slice '{slice.name}': {traffic} Mbps used out of {slice.bandwidth} Mbps allocated. Latency: {slice.latency} ms")

# Create a 5G network with 1000 Mbps total bandwidth
network = FiveGNetwork(1000)

# Create network slices for different use cases
network.create_slice("eMBB", 500, 10)
network.create_slice("URLLC", 200, 1)
network.create_slice("mMTC", 300, 30)

# Simulate network traffic
print("\nSimulating network traffic:")
network.simulate_traffic()

This code demonstrates a basic simulation of network slicing in a 5G network, allocating bandwidth and latency characteristics to different slices for various use cases.
