For packet switching type, the string encoding follows the
type bandwidth-ieee-float32 defined in RFC 8294 (e.g. 0x1p10),
where the units are in bytes per second.
For OTN switching type, a list of integers can be used, such
as '0,2,3,1', indicating 2 odu0's and 1 odu3.
For DWDM, a list of pairs of slot number and width can be
used, such as '0,2,3,3', indicating a frequency slot 0 with
slot width 2 and a frequency slot 3 with slot width 3.
Canonically, the string is represented as all lowercase and in
hex where the prefix '0x' precedes the hex number";
