This often results in a path that passes through the data transfer and is not the best path curre

ideas Defense methods against such traffic attacks include: Set up a hard Firewall Rent anti-DDoS nodes Rent CDN to distribute target traffic Disadvantages Set up a hard firewall: the price of 2G hard defense on the market is about 10 W, and the cluster defense cost is even higher. Although the hardware-level defense performance is high, the traffic flood is also a hit, and the side effects cannot be underestimated. Rent anti-DDoS nodes: Anti-
