2-1-3-3. Switch Cascading in Topology
•Takes the Delay Time into Account
Theoretically, the switch partitions the collision domain for each port in switch cascading that you may up-link the switches unlimitedly. In practice, the network extension (cascading levels & overall diameter) must follow the constraint of the IEEE 802.3/802.3u/802.3z and other 802.1 series protocol specifications, in which the limitations are the timing requirement from physical signals defined by 802.3 series specification of Media Access Control (MAC) and PHY, and timer from some OSI layer 2 protocols such as 802.1d, 802.1q, LACP and so on.
The fiber, TP cables and devices’ bit-time delay (round trip) are as follows:
1000Base-X TP, Fiber | | 100Base-TX TP | 100Base-FX Fiber |
Round trip Delay: 4096 | | Round trip Delay: 512 |
| | | | | | |
Cat. 5 TP Wire: | 11.12/m | | Cat. 5 TP Wire: | 1.12/m | Fiber Cable: | 1.0/m |
Fiber Cable | : | 10.10/m | | TP to fiber Converter: 56 | | |
Bit Time unit | : 1ns (1sec./1000 Mega bit) | | Bit Time unit: 0.01μs (1sec./100 Mega bit) |
| | | | | | | |
Table 2-2
Sum up all elements’ bit-time delay and the overall bit-time delay of wires/devices must be within Round Trip Delay (bit times) in a half-duplex network segment (collision domain). For full-duplex operation, this will not be applied. You may use the TP-Fiber module to extend the TP node distance over fiber optic and
