In the hotel, many people were concerned about prices and brands or what the manufacturer gave them when the purchase network audit gateway was closed."How many users are supported"This is a simple number. But, in practice, several specific performance parameters determine whether an audit gateway can be operated steadily in a real environment. These parameters are not necessarily visible in product information, but the costs of neglecting them are often unexpected problems when equipment is online.
Number of simultaneous sessions
The number of simultaneous sessions is the number of network connections that audit gateways can track and process at the same time. Each device connects to the network, even if it is just backstage synchronous data, will result in multiple sessions. A 200-room hotel with 80% occupancy rate, with some 320 or more live equipment, has already reached over 10,000 joint meetings per unit, on average 20-30 items. If the audit gateway labels only 8000 or 10000 combined calls, there will be a peak period when the session spilles out, leading to the loss of audit records for some links, or even an impact on normal Internet access experience. The selection should be based on the actual number of guest rooms and equipment density of the hotel, with a peak and a distribution of at least 50 per cent of the surplus.
Toss and wire speed processing capability
The maximum bandwidth that the audit gateway can handle. If the hotel's Internet export is 200 Mbps, the audit gateway will have at least a greater amount of throughput than this number, otherwise the gateway itself will become a bandwidth bottle."Maximum value in ideal state", instead of the actual throughput when all audit functions are opened. When you turn on the depth package, logs, traffic analysis, etc., the actual throughput may drop to 50-70% of the nominal value."Actual throughput after full audit functionality is activated", and cannot just look at the nominal value.
New Session Speed
New session speed (CPS, Connections Per Second) refers to the number of connections that an audit gateway can create every second. This parameter is particularly important in hotel breakfast times, check-out peak periods, etc.——If the new meetings are not fast enough, they will be in line and residents will feel a clear network of Caden. The number of new meetings with low-end audit equipment is usually only several hundred to thousands, often insufficient for large hotels.
Log Write Speed
Audit gateways require that each session record be written into the storage device. If log speed does not keep pace with the speed of session generation, the system creates a write-in buffer. During peak traffic periods, if writing is consistently behind speed, it increases in length, either resulting in old logs being discarded or the system collapsing because of the buffer zone. Log writing speed depends on the type of stored medium (hard disk in solid form much faster than mechanical hard disk) and system I/O design. Many low-cost audit devices are mechanical hard disks, which is an obvious bottleneck for writing logs in high-flow environments.
Actual configuration of CPU and memory
The audit gateway is a computer running the audit software, and the configuration of CPU and memory directly affects the load ceiling that it can afford. Many manufacturers do not disclose these basic parameters or avoid them in vague terms. Before procurement decisions are made, manufacturers may be required to provide equipment CPUs and memory specifications or pressure tests at a nearby reference client. A CPU audit facility with insufficient core numbers and only 2-4GB memory, which may remain at 90% or more of the CPU occupancy rate during peak flow periods, systems response slow and log processing delays increase.
Support for high-availability configuration
When the audit gateway is linked to a network export, the entire hotel’s network access will be interrupted if the equipment fails. One device is sufficient for an audit to accept a short interruption; but for a need 7×The two-error heat is the deployment of two equipments, which automatically switch to backup when the main equipment fails; and bypass functions, which are power out or fail, allow for network traffic to pass without audit (at the cost that no audit records are available during this period). Each option has a suitable scenario, and the choice should be based on hotel business continuity requirements.
Querying the response properties of the interface
Audit equipment contains a large number of logs, but the query is not efficient if it is very efficient. A search for an IP visit at a given time can seriously affect the speed of response in emergencies if it takes several minutes to produce results. The responsiveness of the query interface depends on the index design stored by the log, and some equipment has a special index for common search conditions (IP, Time, User ID) that allows fast searching; some equipment have no index, full scan queries, and log volumes are slow after they become available. This parameter must be measured when the selection presentation is done and cannot be read only from the manufacturer ' s text description.
Extended Design
The audit gateway’s performance supports upgrading through upgrades of licences or hardware expansion without replacing the whole set, which is also a matter that deserves recognition during the selection phase. A suitable equipment at this level has been purchased and if the hotel expands three years later, it does not support expansion, and then re-purchases are made.
The performance parameters are behind the real use scene. The selection is not the most appropriate price, but the one that can be run steadily under a physical load.
