In the SDN standard system developed by ONF, in addition to OpenFlow switch specification pairs, there is also a Protocol named OpenFlow Configuration and Management Protocol (OF-CONFIG) also needs to be concerned. As mentioned above, OpenFlow defines a kind of southbound interface in SDN network architecture, and proposes a method for the Controller to send a flow table to the OpenFlow switch to control th

The construction of SDN competition environment and the realization of the first major problemDue to the lack of physical equipment, the virtual machine to implement the Floodlight controller, Openvswitch (hereinafter referred to as: OVS) and mininet all kinds of SDN environment to be used to build. The following will give their construction steps and then use Mininet simulation to give the challenge of the

The second SDN contest--Must answer 2Section 2 Small topic: Access Restrictions@ Wenzhou University 12 Network workersFirst, Experimental BackgroundTo prevent the external server from being D D OS attacks, which restrict access too frequently for a certain period of time. The majority of attacks are blocked by the access control system established for a particular network segment and service before reaching the target of the attack. Second, Experiment

Ryu Topology Discovery principleOpenFlow's official does not prescribe a standard topology discovery method, now OFDP (OpenFlow Discovery Protocol) is still using the Link Discovery Protocol LLDP in the traditional network, and then introduces Ryu how to use LLDP to discover the topology, Suppose there are now two OpenFlow switches connected to the

In October 2012, Midokura with its flagship SDN platform Midonet in the United States. According to Midokura, Midonet is a distributed, decentralized virtual platform that separates users ' cloud assets from the network infrastructure and provides a more scalable and efficient network solution for a highly virtualized cloud environment.1 midonet OverviewMidonet is an open, software-only, highly scalable, resilient network virtualization system. Becaus

It may be useful to use ABAP to schedule jobs in other systems asynchronously. The principle is similar to scheduling event on R3 on BW side, The event returns a successful or failed status to the BW process chain. The detailed process in the following section is derived from Sdn. You can create a job in R/3 to be triggered "after event". Then in your process chain, you create an ABAP process: Call mode: asynchronous Called from: Destination (your R

All the friends who engage in SAP must be familiar with the SDN forum of this sap company. I had nothing to do in the first few days. I simply went online and came to this forum. Http://forums.sdn.sap.com/index.jspa only found that this good thing too much. After a whole day, I realized that this is the forum I have been looking for so long. The Forum is a platform for exchanges between SAP experts from all over the world. There are various questions
