Subject: [dpdk-dev] Release of Packet Journey
Date: Thu, 29 Oct 2015 20:53:41 +0100 [thread overview]
Message-ID: <56327945.3090804@gandi.net> (raw)
Hello,
We have opensourced our dpdk-based project, Packet Journey
https://github.com/Gandi/packet-journey .
Packet Journey is a combinationof Linux RT_NETLINK and severalparts
ofDPDK (rte_kni, rte_lpm, rte_acl, rte_cmdline) and is intended to
serveas an edge router.
Our use case is:
- pktj starts several forwarding threads and a KNI thread per external port
- pktj launches a script which configures the KNI interface (MAC, IP,
VLAN) and launches a BGP daemon
- the host receives routes from the BGP daemon
- the BGP daemon injects the routes in Linux
- pktj receives the routes from NETLINK and put them in LPM in our
"control" threads
- pktj forwards packets to the KNI if the packets are
- for the KNI IP or
- if the neighbor is not known yet
- if ttl reaches 0
- pktj filters packets if they match an ACLor if they exceed the rate
limit, kni output is also rate-limited
- pktj forwards packetsdirectly from the RXqueue to the TXqueue if the
neighbor is known
