OpenFlow Settings
[General] section
Mode:
Select a connection mode to an OpenFlow switch. For example, if you select “Server” mode, Brekeke SIP Server behaves as a server of OpenFlow connection.
Select “Server” mode if you use an OpenFlow switch based on an Open vSwitch (OVS).
Switch (IP address:port):
Enter the IP address and port of an OpenFlow switch.
This field is used when you select “Client” mode.
(Example: 172.16.200.102:6634)
Listening Port:
Enter the port that Brekeke SIP Server is listening for Openflow connection.
This field is used when you select “Server” mode.
(Example: 6633)
Network Gateway:
Enter the IP address of a gateway which is used for data traffic (service network) in the network. If the field is left blank, Brekeke SIP Server tries to detect the default gateway.
Interface Name:
Select the network interface that is used for data traffic (service network).
[Initial Commands] section
You can define initial commands which are executed when OpenFlow connection is established.
The field accepts the same command synatx which dpctl and ovs-ofctl employ.
Example:
------------------------------------------------------------ add-flow ipv6,idle_timeout=0,actions=flood add-flow ipv4,idle_timeout=0,actions=flood add-flow arp,idle_timeout=0,actions=flood ------------------------------------------------------------
[RTP relay] section ※1

RTP packets flow from UA1 to UA2:
Minimum Port / Maximum Port:
Set the range of UDP ports that will be assigned for relaying RTP packets at the OpenFlow Switch.
※1. The switch needs to support OpenFlow 1.0 (Layer 2,3,4).
[Block List] section
Use OpenFlow to block packets:
If you set this setting to “yes“, OpenFlow switch blocks packets sent from the IP addresses that are listed in the Brekeke SIP Server’s Block List database.
Block packets:
Blocking Period(sec):
Set the duration of the blocking flows that OpenFlow switch keeps.
