OPENFLOW IMPLEMENTATION
This section documents aspects of OpenFlow for which the OpenFlow
specification requires documentation.
Packet buffering.
The OpenFlow specification, version 1.2, says:
Switches that implement buffering are expected to expose,
through documentation, both the amount of available
buffering, and the length of time before buffers may be
reused.
Open vSwitch does not maintains any packet buffers.
Bundle lifetime
The OpenFlow specification, version 1.4, says:
If the switch does not receive any OFPT_BUNDLE_CONTROL or
OFPT_BUNDLE_ADD_MESSAGE message for an opened bundle_id
for a switch defined time greater than 1s, it may send an
ofp_error_msg with OFPET_BUNDLE_FAILED type and
OFPBFC_TIMEOUT code. If the switch does not receive any
new message in a bundle apart from echo request and
replies for a switch defined time greater than 1s, it may
send an ofp_error_msg with OFPET_BUNDLE_FAILED type and
OFPBFC_TIMEOUT code.
Open vSwitch implements default idle bundle lifetime of 10
seconds. (This is configurable via other-config:bundle-idle-
timeout in the Open_vSwitch table. See ovs-vswitchd.conf.db(5)
for details.)
