packet switch and circuit switch blocking probability

[rookie1010]

Hello

I was looking at this software and it has got defaults of 2% for circuit switch wireless traffic and 20% for packet switch wireless traffic. are these industry standards?

why is the packet switch blocking probability so high?

Sounds a little like homework, but...

Wireless is always a shared medium (similar to unswitched Ethernet), so if two clients try to send at the same time, or a client tries to send at the same time as the server/switch, you'll get a collision. Since nothing is synchronized, this is inevitably going to happen. A lot.

With circuit-switched networking, you don't have the problem of multiple clients sending at once (or, at least, it's much less likely), so the chances of collision are lower even over a wireless network.

it is not home work, it is actually work work

i was wondering about the Grade of Service(blocking probabbility) of 2 % assigned for circuit switched traffic and a 20% grade of service assigned to Packet Switched Traffic
