With network virtualization, the software switches (such as Open VSwitch) on the servers act like the edge switches. So, to gain insights into the network flow behavior, it becomes important to has some sort of flow monitoring technique t o Analyze the traffic through these switches. NetFlow and SFlow are the "most widely used flow monitoring approaches." To monitor the flows, the switches need to be configured to export and send the traffic data to a
Upgrade DPA 9.1.85 to DPA 10.0.352, 9.1.8510.0.352
The upgrade of SolarWinds DPA is actually very simple. Here we will introduce the process of upgrading from DPA 9.1.95 to DPA 10.0.352. Why upgrade? The emails sent by DPA to users have been clearly written (as shown below). DPA 10.0 has started to support MySQL, and it has fixed some bugs, performance improvement.

②. NetFlow:
____ In recent years, many service providers have been using NetFlow. Because NetFlow has the scalability in a large WAN environment, it can help to support the best transmission stream on the peer point, and can also be used to optimize the infrastructure evaluation based on a single service, the benefits of solving service and security problems provide the basis for service billing.
③. RrdPlugin:
____ Is used to generate a traffic diagram. The author of RRD is also the author of
management interfaces and protocols. Includes NetFlow, SFlow, Ipfix,rspan, CLI, LACP, 802.1ag. Features similar to VMware's DVS and Cisco 1000v. Supports a variety of virtualization platforms (XEN,KVM, Proxmox VE and VirtualBox) and switch chips. Supports a variety of virtualization management platforms (OPENSTACK,OPENQRM, Opennebula and OVirt).Complete list of features:OVS Deployment

Ethernet technology has entered the 10G era. Ethernet is no longer just a LAN technology, but a Layer 2 bearer technology from desktop to core, from enterprises to telecom operators, from LAN to Internet backbone.
As a result, the 10-ge Ethernet switch, as the core of the network, is facing unprecedented challenges. In the past, all the Internet routes, ACLs, sFlow, IPv6 routes, QoS, policy routes, and multicast routes that require routers to handle w
Cisco Security route Configuration documentation introduces the Routing Management and Security Configuration methods, and provides the weak routing configuration instructions. This benefits not only facilitate security workers' understanding, but also become an excellent reference for attackers to exploit vulnerabilities.

Edge Switch Equipment plays a very important role in networking. How can we balance the intelligence and performance of edge Switch Equipment? If the edge switch device of the network integrates QoS, rate limit, ACL, PBR, and sFlow into the hardware chip, the Intelligence will not affect the line rate forwarding performance of the basic layer 2 and Layer 3,
Therefore, the end-to-end smart network can be carried out on a large scale, so that the entire
software, this kind of software is an effective tool to judge the flow of abnormal traffic, through the monitoring of traffic size change, can help network management personnel to find abnormal traffic, especially the flow of abnormal traffic flow, so as to further find the source address and destination address of abnormal traffic.(3) Protocol analysis technology.Protocol analysis technology is used to solve the understanding of what protocols and applications users use, including protocol and
There are many things worth learning about edge switches. Here we mainly introduce a comprehensive description of the intelligent and performance of edge switches. If the edge devices of the network integrate QoS, rate limit, ACL, PBR, and sFlow into the hardware chip, the Intelligence will not affect the line rate forwarding performance of the basic layer 2 and Layer 3, therefore, the end-to-end smart network can be carried out on a large scale, so t
