以下是使用Python实现DWRR差分加权轮循算法的示例代码:
```python
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:
```python
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。
