Rum clue, it's rewritten for network (9)

I believe the answer is:

reticulum

'network' is the definition.
(I know that reticulum is a type of network)

'rum clue it's rewritten' is the wordplay.
'rewritten' indicates anagramming the letters.
'rum'+'clue'+'it'='rumclueit'
'rumclueit' is an anagram of 'RETICULUM'.

'for' is the link.

(Another definition for reticulum that I've seen is " network".)

I've seen this clue in The Times.
