Hello Ali, Thank you again and I'm sorry for bothering so much. After all this time theres one thing that I couldn't really figure out: Suppose I have only one FlowSpace rule giving WRITE permissions to ALICE, and the match of this FlowSpace rule is dl_vlan=1. ALICE then tries a FLOW_MOD (with an

Hello Ali, Thanks again for the quick and so helpful support. I've been looking at the code for quite some time now, and some things seem specially tricky for me to understand: 1) When I send a FLOW_MOD with an Action to change de DL_VLAN, we talk about SwitchFlowMap, which seems to come from t

Bootstrapping OpenFlow requires a configuration protocol like OF-Config or ovs-vsctl. Enabling sFlow sampling in the switch forwarding plane can easily be handled through a common configuration protocol. OpenFlow and sFlow share many architectural similarities. In the same way that OpenFlow moves

Hi, Looking at the proposal, it seems it could be implemented with existing group entries (available since OF 1.1). Just install a select group with two buckets, one sending packet_in's, the other dropping packets, and set the Bucket weights to get the desired sampling rate. OpenFlow 1.3 also ad

Hello, i would like to suggest an extension to the OpenFlow standard for packet sampling. I already presented the extension at this years SIGCOMM in the poster session and now i would like to know how you people think about the idea. In environments with a high arrival rate of new flows, such
