Subject: [dpdk-dev] [RFC] Add RIB library
Date: Tue, 11 Jul 2017 19:33:04 +0000 [thread overview]
Message-ID: <1499801585-10031-1-git-send-email-medvedkinv@gmail.com> (raw)
Hi,
I want to introduce new library for ip routing lookup that have some advantages
over current LPM library. In short:
- Increases the speed of control plane operations against lpm such as
adding/deleting routes
- Adds abstraction from dataplane algorythms, so it is possible to add
different ip route lookup algorythms such as DXR/poptrie/lpc-trie/etc
in addition to current dir24_8
- It is possible to keep user defined application specific additional
information in struct rte_rib_v4_node which represents route entry.
It can be next hop/set of next hops (i.e. active and feasible),
pointers to link rte_rib_v4_node based on some criteria (i.e. next_hop),
plenty of additional control plane information.
- For dir24_8 implementation it is possible to remove rte_lpm_tbl_entry.depth
field that helps to save 6 bits.
- Also new dir24_8 implementation supports different next_hop sizes
(1/2/4/8 bytes per next hop)
It would be nice to hear your opinion. The draft is below.
