[ovs-discuss] Multipart request interleaving with individual request

[Hariharan_Sethuraman at Dell.com]

Hi OVS team,

I am working in opendaylight. Would like to get the following clarified.


1.       Can a multipart reply mix up with individual reply causing invoking client out of sync with OVS?

For example:
ofp_port_stats_request is a request for individual port statistics. Ofpmp_multipart_request can be a request for more port statistcs.

Lets say the SDN controller, requests ofpmp_multipart_request and ofp_port_stats_request in any order to OVS. When OVS is constructing the replies and a port status flaps (up to down) in between, is there a chance of replies is in the order such that the SDN controller receives the replies and sees the port status as down in first reply (ofp_port_stats) and up in multipart replies? So at the end the controller thinks the port status is up but the port status is down in ovs. Is this possible? Or the mutlipart reply is always the live status and not built on buffered?

Thanks,
Hari
