First, be clear:The bandwidth is calculated according to small b.The flow is calculated according to the Big B.Suppose a website traffic is 4000gbyte/month, many people do not have the concept, this is how much bandwidth (unit is Mbit/s)? And how much IP access can this 4000GB traffic support?First, you figure out how much PV your site has (page visits, 1 Independent IPs may have multiple PV)And then we'll
