A bureau uses s5500+s2300 Network Way, because the upstream light path resources are less, so in the Community adopt S2300 Cascade Way, Cascade uses 5 class twisted pair, the user uses the PPPOE Way to surf the internet. After opening, some two-level switch users reflect slow internet speed. Process steps:The first step, the

request is more time-consuming, but these are the problem of the statistical platform, we can not solve.Iv. finalWell, about the statistical code, universal existence of the two trap art has been demonstrated and provide a solution to the method, you can view the webmaster's own website, if you feel that the art is not reliable, their own use of the test time to know, after all, dry this line is to rely on data to speak!In addition to the statistical

Symptom descriptionA certain Bureau adopts the MA5200 + 2403F networking mode. Due to the small amount of upstream optical resources, the 2403F cascade mode is adopted in the residential area, and the cascade mode adopts five category of twisted pair wires, you can use PPPOE to access the Internet. Some second-level switch users report that the Internet access speed
