Hello, We are students trying to extend OVS in the Linux environment for our research works. We have primitive understandings of OVS after reading the documents. However, we are uncertain whether we are on the adequate track. The new features of our design and our speculated starting points are
1) Feature Collecting statistics (e.g. total bytes transferred) at each switch port. Speculated starting point netdev_linux_get_stats() in lib/netdev-linux.c 2) Feature Post processing statistics collected in (1). Speculated starting point lib/dpif-netlink.c Adding our algorithm. 3) Feature In-band exchange of processed statistics in (2) between OVSs. Speculated starting point lib/dpif-netlink.c We still do not know how to inject our own control packets into datapath. Do we have to trace how OVS processes the "PACKET_OUT" OpenFlow message? 4) Feature Good performance comparable to original OVS. Speculated starting point lib/dpif-netlink.c and datapath/datapath.c Customizing existing dpif to call only kernel-level functions in datapath/ to achieve (1), (2), and (3). Please give your valuable suggestions and comments. Many thanks in advance! _______________________________________________ dev mailing list d...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-dev
