Software Release 4.1
Example Allocation
At AP default downlink-to-uplink settings (75% downlink and 25% uplink), if High Priority is set to
25%, then
• in the uplink, the total of reserved slots is equivalent to 25% (2 slots in this example)
and
− the bandwidth is 64 bytes per slot, repeated 400 times each second.
− [2 slots/instance] x [64 bytes/slot] x [8 bits/byte] x [400 instances/second] = 409,600 bps
≈ 400 kbps of uplink bandwidth
• in the downlink, the AP
− does not reserve slots, but will service all high-priority bandwidth requests.
− may become saturated by attempting to service too much high-priority traffic.
− monitors the Low Latency TOS (Type of Service) bit, Bit 3, in the Ethernet frame.
− prioritizes the traffic in the high-priority queue (when Bit 3 is set) according to the
AP configuration settings for the high-priority channel.
4.4 BRANDING
The web-based interface screens on each Canopy module contain the Canopy logo. This logo can
be replaced with a custom company logo. A file named canopy.jpg generates the Canopy logo.
Procedure 1: Replacing the Canopy logo
You can replace the Canopy logo as follows:
1. Copy your custom logo file to the name canopy.jpg on your system.
2. Use an FTP (File Transfer Protocol) session to transfer the new canopy.jpg file to the
module, as in the example session shown in Figure 10.
