OF-CONFIG protocol for SDN southbound Interface Technology

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

[Original] Record of the first SDN tournament-part

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

Improved topology Discovery performance for SDN controllers (through improved logic)

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

Sdn Start-up Midokura and its product introduction

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.

Running a R/3 job in BW process chain (finishing SDN)

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

SDN is an SAP communication platform

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

Proactive vs. reactive

Not long ago a PhD student and blogger who studied Sdn complained: "Now the Open Source SDN controller performance is poor Ah, 2K a new stream per second will prompt packet-in too much, stop working." The blogger asked how he defined a stream, which he said with TCP 5 tuple. The blogger asked him how he produced such dense packet-in, he said, using a server to send packet-in directly to the

What is the intersection between a Software Defined network and an ADC?

The entire concept of Software Defined Network (SDN) is about abstracting hardware to enable new types of network streams. Although many early discussions on SDN are concentrated on routers and switches, SDN does not stop here. SDN has many functions, including helping WCO and application delivery controller (ADC) busi
