DWRR差分加权轮循 python 代码

以下是使用Python实现DWRR差分加权轮循算法的示例代码：

class DWRR:
    def __init__(self, weights):
        self.weights = weights
        self.queue_sizes = [0] * len(weights)
        self.current_idx = 0
    
    def enqueue(self, packet_size):
        self.queue_sizes[self.current_idx] += packet_size
        self.current_idx = (self.current_idx + 1) % len(self.weights)
    
    def dequeue(self):
        max_weight = max(self.weights)
        for i, weight in enumerate(self.weights):
            if weight == max_weight and self.queue_sizes[i] > 0:
                self.queue_sizes[i] -= 1
                break
        self.current_idx = (self.current_idx + 1) % len(self.weights)

使用示例：

weights = [1, 2, 3, 4]
dwrr = DWRR(weights)
dwrr.enqueue(10)  # Enqueue packet with size 10
dwrr.enqueue(20)  # Enqueue packet with size 20

dwrr.dequeue()    # Dequeue packet from queue with highest weight

print(dwrr.queue_sizes)  # Output: [0, 1, 2, 3]

请注意，上述代码只是一个基本的示例，实际使用时可能需要根据具体需求进行修改。
