The reason for switch3 is, switch2 ran out of ports when the campus site(switch1) was added. All the equipment is in one room. Switch1 to switch2 is connected via fiber because switch1 is at a remote campus building.
The Internet connection is to be added. The reason for having the Internet connection at the location of switch4 is that is the only site that ADSL is available. I was concerned about the traffic that was destined to the Internet gateway from the source switch1. I thought there maybe a bottleneck at the point where data is passed from switch2 to switch3. It seems with this design there should not be any latency issues. If I could ask you another question,(possible future addition) what if switch1 was located on another subnet. The subnet is connected via ISDN(128K). Does anyone see any problems with traffic going across an ISDN link to switch to wireless link to switch to Internet.
