Yes. Once the TCP window fills up between OVS and the controller, OVS

Dear Ben,
thank you for your response. I am currently continue to test OVS and
investigated another following problem:
I increase number the load - 500 UDP flows with 10 consequent packets in
each of them sent in 0.2 sec interval. miss_send_len is set to 65535, no

Hello Ben,
thank you for help!
as Open vSwitch stores only 256 Packet_Ins in buffer (OFPT_FEATURES_REPLY:
n_buffers = 256) after 256 packets it sets Buffer_ID to 0x.
Controller didn't check this value as incorrect and placed it into
responses in flow_mods and packet_outs, that caused packe

No, Open vSwitch just accepts all the rules (500) and installs them without
sending any errors to a controller, but processes only part of ingress
packets through them:
ovs-ofctl dump-aggregate br0
NXST_AGGREGATE reply (xid=0x4): pa
Does the controller get any error replies from Open vSwitch?
What's in the ovs-vswitchd log? (Not in debug mode, that's too big.)

Dear Ben,
I figured out that drops occur inside OVS. I see all packets entering one
interface of OVS, Packet_In generated for every packet, then Flow_Mods (or
Packet_Out in other tests) generated and sent for every Packet_In by
external controller and all this rules are installed to OVS. Namely 50

Hello all,
I test Open vSwitch in the following scheme: I use 2 hosts directly
connected to OVS and external OpenFlow Controller. Host1 generates UDP
datagrams with sequential ports towards Host2, Host 2 listens for these UDP
datagrams. In responce to every UDP datagram OVS generates Packet_In an
