Last week, the Telecom technician came to my door again, saying they suspected I had PCDN at home. The basis for suspicion was a large amount of upstream and downstream traffic for 215 consecutive hours (actually, I downloaded very little during this period, less than 1T of downloads in 215 hours, and upload was not even 300G~). I was speechless. My Transmission upload limit is already set to 1024 KB/s, what else do they want me to do?
Just looking at the recent online cases of users being speed-limited or disconnected by operators under the guise of PCDN, it feels like major operators are using PCDN as a catch-all excuse to crack down heavily on users with large upload volumes (this ”large” is relative to average home users; you know, an average home user's upload might not even exceed 1G a day~) so I also felt the danger: after all, I am an old user using a public IP package at a very low price, which makes me a thorn in Telecom's side. If they catch an opportunity to claim I violated the rules and take back my public IP, it would be a huge loss (although I don't really need a public IP right now, but not taking advantage of a good deal is just foolish).
After thinking it over, and combined with the experience of being disconnected by Telecom for 3 days last year, I already had a sense of crisis. So I simply got another Mobile gigabit broadband line, claiming 1000 Mbps downstream and 100 Mbps upstream.

Believe it or not, there really is nearly 130 Mbps upstream:

After more than a week of tinkering, I completed the traffic splitting for the intranet terminals. Terminals related to the home data center go through Telecom, while other applications (including PT downloading) go through Mobile. The Mobile egress is set as my home's default egress, while the Telecom and Mobile egresses serve as backup lines for each other. Now, except for power outages, I no longer worry about access issues for some applications due to broadband problems. Although it was a forced addition of Mobile broadband, I suddenly feel that dual broadband indeed brings a greater sense of security. At the same time, it can be considered as fulfilling my long-held wish for dual broadband~~~.
确实，我电信家宽只跑PT最近也被标记PCDN，第一次去营业厅办完手续后很快解除限制，没过多久又被限制，后来跟我说没得解封，现在是用github上某个项目绕过限速，公网IP还在，但分配的是本省其它地市的IP。以前用过爱快，由于没有硬件加速，且免费版不支持同时绑定多条IPv6，后来改为用mt7986带HNAT的ImmortalWrt，也接入了移动1000M（南方移动贼抠门，千兆宽带上行只给40M），用mwan3简单分流。
我家宽带是老套餐，有公网IPv4而且还可以3拨(3个公网IP)，同时也支持IPv6，所以现在不太想用电信宽带乱折腾，如果被电信趁机收回IPv4公网IP就亏大～。由于我很多年前就玩PT，那时还没PCDN的概念，一个人的上传流量可以顶一个小区，所以在电信本来就是挂了号的重点监控人物，老实说电信对我其实已经很宽容了。去年因为扫描到我爱快上的远程管理口并被通管局跨过电信直接封了我的账号3天，电信后来被我投诉后出来背锅，赔了我一个月网费，所以其实电信在遇到要对付我的时候，都很小心，不会像一般用户那样肆无忌惮的出手。不过，我PT早就毕业了，对上传其实已经无所谓了，加上现在这个形势，我还是想尽量让我电信的流量干净，主要用来给我家庭数据中心中的重要应用使用，所以把PT和其他流量都迁移到移动线路上。但是让我比较惊喜的是，把移动光猫改为桥接，直接用爱快拨号，获得的虽然是100开头的私有移动，但是，NAT类型是”Endpoint-Independent NAT”，PT还是可以玩一下的。
现在运营商都部署了检查pcdn的服务器，一查一个准
如果要查肯定可以准确定位的，不过，现在看来，更多的是用pcdn当万金油进口，整治目标是所有超过”正常用户”上行流量标准之外的用户(包括直播)，有些快递驿站都被封了号，就因为每天扫描上传的流量大了～～。
PCDN现在误判的也是有很多，莫名其妙的
不是误判，要真判断了才有误判的情况，现在纯属是就以”上传”量一刀切，按移动师傅的说法，80%-90%都是冤枉的～。
