The spec. is not too long; it probably worth reading it (the first four paragraphs). Matching on sequence numbers is not possible without coding. With coding everything is possible. In your case I think you'd even need matching (and wildcarding) on bits of the sequence number, unless you want to

Well, this is also somewhat theoretical (as it has not been tested yet :o)), but in [1] I implemented select groups as a weighted round-robin of the buckets, without any hashing (around [2]). Anyway, if anyone is interested in using this feature, I'll promise to fix any problems that might arise

Hello, I am trying to split a flow so packets take two different routes... For example every odd packet goes out of port 1 and every even on port 2, however I am struggling to figure out how exactly this is done (if possible at all). I know that the tables on the switches keep flow statistics suc
