-/*
- Comparing to general packet classification problem,
- RSVP needs only several relatively simple rules:
-
- * (dst, protocol) are always specified,
- so that we are able to hash them.
- * src may be exact, or may be wildcard, so that
- we can keep a hash table plus one wildcard entry.
- * source port (or flow label) is important only if src is given.
-
- IMPLEMENTATION.
-
- We use a two level hash table: The top level is keyed by
- destination address and protocol ID, every bucket contains a list
- of "rsvp sessions", identified by destination address, protocol and
- DPI(="Destination Port ID"): triple (key, mask, offset).
-
- Every bucket has a smaller hash table keyed by source address
- (cf. RSVP flowspec) and one wildcard entry for wildcard reservations.
- Every bucket is again a list of "RSVP flows", selected by
- source address and SPI(="Source Port ID" here rather than
- "security parameter index"): triple (key, mask, offset).
-
-
- NOTE 1. All the packets with IPv6 extension headers (but AH and ESP)
- and all fragmented packets go to the best-effort traffic class.
-
-
- NOTE 2. Two "port id"'s seems to be redundant, rfc2207 requires
- only one "Generalized Port Identifier". So that for classic
- ah, esp (and udp,tcp) both *pi should coincide or one of them
- should be wildcard.
-
- At first sight, this redundancy is just a waste of CPU
- resources. But DPI and SPI add the possibility to assign different
- priorities to GPIs. Look also at note 4 about tunnels below.
-
-
- NOTE 3. One complication is the case of tunneled packets.
- We implement it as following: if the first lookup
- matches a special session with "tunnelhdr" value not zero,
- flowid doesn't contain the true flow ID, but the tunnel ID (1...255).
- In this case, we pull tunnelhdr bytes and restart lookup
- with tunnel ID added to the list of keys. Simple and stupid 8)8)
- It's enough for PIMREG and IPIP.
-
-
- NOTE 4. Two GPIs make it possible to parse even GRE packets.
- F.e. DPI can select ETH_P_IP (and necessary flags to make
- tunnelhdr correct) in GRE protocol field and SPI matches
- GRE key. Is it not nice? 8)8)
-
-
- Well, as result, despite its simplicity, we get a pretty
- powerful classification engine. */
