Comparison of real bandwidth of several IDC data centers in Shanghai

Currently, Shanghai telecom resources can be roughly divided into several types:
1. shanghai Changxin: Shanghai 163G bandwidth access, the telecom branch has of the total egress in Shanghai. Currently, all the machine rooms of this company are distributed as follows: wusheng (Shanghai bandwidth core access point ), hengbang (access on the 12th floor, IDC on the 14th floor, temporarily closed on the 20th floor, with 40 Gbit/s of bandwidth directly connected to Wusheng), Hua Mu (the IDC has 20 Gbit/s of bandwidth and 10 Gbit/s of Wusheng, 10g Heng Bang), such as (currently two 2G bandwidth, one connected to Heng bang, one connected to Wu sheng), Zhang Dong (two 2G bandwidth, one connected to Heng Bang, A flower tree)
2. shanghai Hotline: (belongs to China Telecom's three products) there are currently Waigaoqiao, Zhangjiang Data Center, Information Building, and Smart Square. These data centers are all connected by bandwidth from the three production data centers and are not associated with Wusheng and hengbang, currently, the external High has two 2G bandwidths, Zhangjiang 2G bandwidths, and the information building 2G. Smart Plaza has a very small bandwidth and has not reached G.
3. xinnet: (responsible for Shanghai metro networks, such as ADSL access in common residential areas, this company is responsible for implementation) currently there are Haining, Guoli, Yunlian, Tongpu, Fenyang, Fuhua, and so on. Due to the long time, therefore, the IDC facilities are outdated. these data centers are not associated with Wusheng and hengbang. In addition to the 2G bandwidth of Yunlian and Tongpu data centers, the bandwidth of other data centers is very small.
4. data: (leased line access only) the above is the current IDC market in Shanghai. If you want to select a data center, we recommend that you select the Changxin data center because the outbound bandwidth of Shanghai is within the control range of Changxin.
