Our approach involves understanding unique enterprise needs, unlike basic home internet requirements, and implementing effective strategies like QoS to manage bandwidth usage efficiently. Stay ahead with DELine's tailored WAN optimization services, ensuring reliable and high-performing network connections for your business operations in China
Most of the European companies in China have been suffered or are still suffering with their network connection to their headquarters. Some of them complain about the high cost but low performance of leased line which was signed globally by the HQ; some complain about the slow and unstable VPN connection based on their local internet line; some also struggling to getting access to the blocked websites… Problem is never such simple, let’s look at what’s the main causes which would affect the experience of network usage:

1. network speed – bandwidth

When ISP sells a broadband line to a user, the ONLY feature they talk about is the bandwidth, which is normally to be called the network speed. Home users already get upgraded from ADSL (2-4Mbps) to ADSL2+ (up to 25Mbps) to nowadays EPON fiber (100Mbps). But enterprise users when they start a new installation, some of them are still looking in the way they order their home internet line. They should realize that’s different.  It doesn’t mean that bandwidth is not important for companies. But we need another view of it.  For home internet, the most usage is to surf the internet, to download or stream video/music. This way the data always comes from the server to the client as requested. That’s also why the home internet products are always asymmetric with the download/upload bandwidth. For example, by ADSL the upload rate is 1/8 of the download rate. But in the enterprise world, at first the most traffic used on the line should be business necessary, not video/music/game, that’s why the bandwidth for serious companies should not be as much as home users. Then the data transfer is most of the time bidirectional. Branch office clients download data from headquarter data-center; headquarter gets data backed up from branches; don’t even to mention video conference and Voice-over-IP application. That’s the reason that the upload rate should also be taken seriously. We did a survey in 2015 based on our monitoring data:
company PC user bandwidth (Mbps) other locations top bandwidth consumer APP frequency bandwidth full Methods to save bandwidth
Mxx 40 2 1 HTTP 1 per month QoS
Chxxx 40 2 3 SAP 1 per week QoS
Mxxxx 150 10 4 Lotus Notes 1 per week QoS, Proxy
You can see with some control of the bandwidth usage and good training for internet usage, even a company with most HTTP connection, will not reach their bandwidth. Therefore, if a ISP comes to a company and try to sell their internet line only focusing on how cheap they can provide you for a 100 Mbps line without any other feature. This line might not be that good for you. And the “other features” we meant here for the business line, will be discussed in the next post.
