Open VSwitch (OVS) is the most popular open-source virtual switch on the Linux platform. Because today's data centers are increasingly reliant on software-defined Networking (SDN) architectures, OvS is rapidly being used as a network element in the fact standard of the data center SDN deployment. Open VSwitch has a built-in logging mechanism, which is called vlog. The Vlog tool allows you to enable and cust

appropriate server to connect. When these concepts have been identified, the next step is to make choices in terms of functionality and cost. L4 Price is not expensive, but the relative L7 equipment is insufficient. But let's think about it another way, if we split the namespace of each protocol and give different virtual IP addresses, it seems like we can make the L4 area separate from the service request. If the cost of doing this is more than buying a F5, then buy an honest F5 (laughter

Opendaylight is a community-led, open-source project supported by the industrial chain, which launches anopen-source framework called "opendaylight", designed to promote innovation for a more stable, A secure way to define a network transition to software. As long as you focus on SDN technology, you can't pay attention to opendaylight. In order to better promote the development of Opendaylight related technology in China, let more developers understan

APT is an advanced persistent threat,A "puddle-type" attack, usually referring to an attacker's network activity through the current popular social engineering analysisRules, looking for vulnerabilities and weaknesses in websites that are frequently visited by attackers, using a variety of technical means to compromise sites that are trusted by attackers, and to embed attack code or Trojan horses.

About routing service in OpenFlow Network (1) Here, the so-called OpenFlow network refers to a set of OpenFlow switches connected to each other, and all these switches are placed under the management of an OpenFlow Controller or an OpenFlow Controller cluster. The routing service of OpenFlow network refers to simply sending a Packet from one Host to another, rather than implementing layer-3 IP routing protocol. The host is also the destination of the route. It can be a physical server or Virtu

In the previous article, we talked about the most basic SDN, that is, how do clients with CA addresses access the external network? Is there a concept like "VLAN virtual gateway" in Network virtualization? And how does the specific connection between PA and CA be realized?The network architecture involved in this article, because it is SCVMM advanced, the SCVMM part of the separate extension, with the advance of the SCVMM advanced, will continue to up
