Dell-on-Dell advantage
When a SmartBytePro enabled machine starts a Priority 1 application or a
priority 2 application, it will send out an encrypted, broadcast message
indicating that a high priority application needs bandwidth. It will send out this
message once every N seconds while the high priority application is actively
sending/receiving traffic. All other SmartBytePro systems on the same LAN will
receive this message and lower the maximum bandwidth used for traffic
shaping by K mbps.
Manual bandwidth control
Manual bandwidth control is used to conform downlink speeds to values
entered by the user. User can set the speeds either by entering the numbers
manually or by performing the speed test within the application.
This regulation is achieved by tricking the AP to provide more bandwidth to the
high priority applications by lowering the bandwidth to low-priority applications.
Though it provides higher bandwidth to high priority applications, the overall
operating bandwidth is 93% of the limit set in the application. If speeds are
below the limits, Smartbyte will not regulate bandwidth.
Dynamic bandwidth control
Dynamic bandwidth control is an enhancement to Manual bandwidth control. It
estimates the bandwidth of the newly connected APs. The estimation is
performed by sending very small packets and tracking the latency of these
applications. Latency gives more insight about congestion. Dynamic bandwidth
control also let user bump the limits set in the application whenever additional
bandwidth becomes available. Also, it will regulate bandwidth if the user is
experiencing speeds up to 80% of the limit set.
Access point scoring and ranking
This feature lets the user see all available access points and their scores in
terms of bandwidth. Each access point is scored using 5 factors: Signal
strength, Maximum data rate, MU-MIMO capability of the access point, channel
contention and loading of the channel. These factors are acquired from the
access point beacon and uses a proprietary scoring mechanism to combine
these factors.
Speed to router
Internet speed with wireless is determined by 2 factors: Connection quality of
the client device with AP and backend congestion. Any of these 2 factors can
be a reason for low speeds. This feature exclusively represents the connection
quality with the access point.
Smartbyte Solution Walkthrough and Use Cases
Smartbyte detects the application and maps it to the priority based on a look up
table. It has priority assignments to more than 40,000 applications and the table
is pretty much exhaustive. The priorities are as follows:
Real time application – 1
Video streaming – 2
Other web traffic – 3
Background downloads – 4
Unknown applications are assigned a priority of 3.
