As mentioned in my previous entry I started with 100Mbit, considered 1000Mbit and reversed to 100Mbit. The reasons to stick to a more conservative 100Mbit are many:
- Cost for 100Mbit is ca 1/4th of cost for 1000Mbit.
- Very few PLC type systems support 1000Mbit on daisy chain designs.
- And the hard fact is that a 10Mbit system is sufficient for the signaling used in most configurations.
- Complexity on routing increased dramatically.
All in all I concluded that the benefits of having 1000Mbit was to small to justify the extra cost and risk.
