Echelon LonWorks Router - Manual (Page 29)

Example: For a 20 MHz Router 5000 device (where both halves use the Router
5000 chip), a measured data transfer rate for sending a service-pin message
between the router halves was approximately 1.2 μs per byte (or 830 kbytes/sec).
Some additional latency was seen for the time between the beginning of the
original packet transmission and the beginning of the forwarded packet
transmission.
For slower channel types, this router latency is not significant, but could become
significant for faster channel types.
The latency between router halves is relatively invariant, with respect to router
configuration, whereas overall router latency depends on the router type and
configuration. For an RTR-10 device, the maximum data transfer rate between
router halves is approximately 2.4 μs per byte (or 416 kbytes/sec). For a Router
5000 device (where both halves use the Router 5000 chip), the maximum data
transfer rate between router halves is approximately 600 ns per byte (or 1.6
Mbytes/sec, assuming a 40 MHz system clock for both halves; this rate scales
with the system clock setting). An FT Router 5000 performs similarly to the
Router 5000.
