an APP Server, that is to say, traffic is terminated locally, the future architecture may look like this, as shown in: Looking at the figure above, you may ask, how does the device know that the data packet is sent to the local device? In fact, this is not the responsibility of this device. How do you know that what I DMA to the Ring buffer is an Ethernet frame instead of a pure HTTP packet? In short, there is no such thing as the present, which is incredible. What's best about PF_RING is not

not the only choice, because even AWS seems to be aware that the pattern has changed a lot, so the new idea: AWS Re:invent, similar to the previous years Sohu proposed: Cultural reengineering.5. With OpenStack-led vendors pushing SDN projects to the ground, private hosting cloud and intra-company virtualization environments accelerate convergence. The first batch of large-scale customers will appear in companies with big data and in the Internet busi

is the complexity? Complexity is added by future generations! It is not the core of TCP/IP. If we maintain the core of TCP/IP and connect the gully between June A and June B with a bridge like the San Francisco bridge, the efficiency will be greatly improved, therefore, QoS is the transmission network (as the link layer ?) !Addressing network in a new generation of Network Independent into a signaling network, its goal is to configure all-optical transmission network, similar to the work of the

Label: SDN Ryu 1. Basic Framework and Development instructions of Ryu From the framework, we can see that in the Ryu controller architecture, including non-of protocols, of protocols, various libraries, and embedded apps, the Ryu Controller provides a unified rest API for users to develop their own apps Based on the Ryu framework. At the same time, developers can develop their own apps based on their own needs. Add the required components and librar

Vswitchd is a user-state daemon process. Its core is to execute the ofproto logic. We know that ovs is implemented in accordance with the openflow switch specification. Taking Layer 2 packet forwarding as an example, a traditional switch (including the implementation of Linux Bridge) searches for a cam table, find the port corresponding to the DST Mac, while the implementation of the open vswitch is to find whether there is a corresponding flow based on the input package SKB. If there is flow, i

Tags: OpenStack network open source Neutron Virtual SwitchNow, when it comes to virtual switches, it's common to think of using open vswitch as a virtual switch because both individuals and businesses that support open vswitch want an open model to integrate their services into OpenStack. The open Vswitch community has done a lot of work to improve the position of open vswitch as the primary virtual switch. The community expects open vswitch to provide all the best possible switching services wh

Openflow switch Application Mode Researchers at Stanford University proposed that Openflow had two original intentions: first, they needed to conduct innovative network research and wanted to separate the control layer functions of network devices from physical devices, to control and modify the behavior of network devices through programming as needed. Second, we hope to build a new universal network data forwarding plane to meet the requirements of future network development, the stream table

States, it is difficult for hackers to break through the hypervisor to the kernel layer and to bypass such security monitoring. The second case is that users cannot obtain the underlying interfaces of the virtualization platform, or want to use third-party security control measures (the security managed by the virtualization platform and controlled by themselves is confusing ). This method is a popular security control measure for traffic redirection by security manufacturers. The idea of imple
