Bandwidth complaints are one of the most common problems in the operation of WiFi, but many hotel IT teams deal with such complaints firstly:"And a bandwidth."Instead of analysing what the bandwidth is taken, who took it, how long. In fact, most of the bandwidth is reasonable."WiFi is slow."The complaint is based on the lack of a rational bandwidth management strategy, not on the fact that bandwidth itself is insufficient. This article sums up the idea of bandwidth management in the WiFi certification system at the hotel from the point of view of its actual configuration.
The hotel WiFi's typical distribution of bandwidth consumption
In the WiFi network of hotels without any bandwidth management strategy, bandwidth consumption is usually visible."Distribution of XXVIII"Some 20% of equipment consumes 80% of bandwidth. These 20% are often devices that download large files, video caches, P2P transfers or software updates. These actions are not per se illegal, but they almost fill the network ' s bandwidth without speed limits, resulting in a very poor experience for the remaining 80% of users.
The central objective of bandwidth management is to prevent the uncontrolled appropriation of shared bandwidth resources by a few equipment without compromising normal experience of use.
Basic configuration logic for single user bandwidth limit speed
Single-user bandwidth limits are the most basic bandwidth management tool. Several questions need to be answered when configured: What is the maximum available total bandwidth? What is the number of users expected to be online at the same time? What level of basic user experience is expected to be achieved?
Take the example of a 200 Mbps total bandwidth, expected 100 simultaneous online users: if distributed equally, this figure is more stressful for video calls; if the actual co-exist rate (which usually does not reach 100 per cent at the same time), each user can be allocated a ceiling of 10-20Mbps, with a reasonable coefficient of total user traffic not exceeding total bandwidth (e.g. 80 per cent).
It is sometimes less flexible to simply set fixed ceilings, and it would be more reasonable to do so"It's normal to relax and tighten when you have a jam."——This dynamic speed-limit mechanism improves overall experience more than the fixed speed limit.
Speed limit by type of operation
In addition to using user speed, a different strategy can be used by type of traffic. The usual categories are: video traffic (e.g. Netflix, YouTube, Juicy), ordinary Web browsing traffic, file download traffic, P2P transfer traffic.
The speed-limit strategy for video traffic requires particular caution: it is a bad experience if the speed limit of video traffic is too low, leading to frequent video buffers; but if not, video traffic can easily absorb large bandwidth. A compromise solution would be to set a reasonable downline ceiling on video traffic (e.g. 30Mbps) to ensure that 1080P stream media are aired smoothly while preventing uncontrolled consumption bandwidth.
P2P traffic (e.g. BT downloads) is usually recommended to be more restrictive or even blocked, as it is characterized by continued bandwidth occupancy and insensitivity to delays, the type of flow that makes it the easiest to create bandwidth congestion in a hotel-sharing network.
Mechanisms for achieving equitable use strategies
The core of Fair Usage is that each user has a relatively equal access to network resources in the event of cyber congestion, rather than having one user over-bandwidth first. Achieving equitable use strategies usually requires several mechanisms to work together.
The first is traffic monitoring: a system of real-time statistics on traffic consumption per certified user, identifying abnormally high consumption users. The second is dynamic QoS: temporary reduction of bandwidth distribution for users beyond normal consumption thresholds and automatic lifting of restrictions once their traffic resumes. The third is priority queue: higher priority is given to delayed sensitive flows (e.g. video calls, VoIPs) to ensure that such flows are not over-queued during congestion.
A. The application of daily flow quotas
Some hotels consider setting a daily flow quota (e.g. 10GB per day per tenant) beyond the back-down speed. This strategy is meaningful in specific contexts, such as where the hotel itself has very limited overall bandwidth and needs to be strictly cost-controlled.
But in urban business hotels or high-end resorts, daily traffic quotas are easily triggering complaints from residents, especially commercial tenants——They may need to download a lot of working papers in one day. For such scenarios, it is suggested that there be no total quota but that the occupancy be controlled by real-time bandwidth limits rather than quotas."It's stuck."User.
Common error in bandwidth management configuration
In actual projects, bandwidth management configurations are prone to several typical errors: low speed limit values have been set, resulting in frequent video calls and videoconferences being used; speed limit strategies are not linked to the authentication user level and VIP tenants and dispersed passengers use the same speed limit template; there is no continuous monitoring after bandwidth policy configuration to detect strategy failures or unusual traffic in a timely manner; speed limits are only configured down and do not go up, leading to uploading large files with full bandwidth and affecting all users ' network delays.
Bandwidth management is not a complete task, but needs to be continuously optimized in conjunction with actual operational data. Regular review of bandwidth use reports and analysis of the flow composition during peak periods are necessary for more accurate strategic adjustments. A practical habit is that the bandwidth strategy is repeated quarterly, comparing user complaints records, bandwidth utilization curves and speed-bound frequency times, often finding parameters too conservative to set and areas where bandwidth demand is growing but not keeping pace with strategy. The ultimate goal of bandwidth management is to make residents feel less comfortable."It's a speed limit."This is a sign of strategic adaptation.
