be congested or even "paralyzed ". On the other hand, AC accounts for a large proportion of the total network cost. To solve the single point of failure caused by AC, enterprises have to pay for redundancy.
AC seems to be the performance bottleneck of the entire wireless network. If we abandon the AC and rely solely on the AP, can the enterprise's wireless network still operate normally? Can enterprises expand linearly without changing the original network architecture?
Cisco Meraki local management interface firmware Installation Vulnerability (CVE-2014-7999)

Affected Systems:Cisco MerakiDescription:CVE (CAN) ID: CVE-2014-7999
Cisco Meraki is a cloud management solution.
A security vulnerability exists in the local management interface of the Cisco Meraki device. authenticated remote attackers can e
Today, most enterprise-class WLAN products and many SMB products offer built-in guest management capabilities. From simple forced network portals and firewalls to traffic shaping and unique guest logins, such products can be automatically generated without it assistance. For example, let's look at the guest management capabilities provided by the enterprise-class WLAN cloud controller in Meraki. In order to create a

For example, PowerCloud introduced how its technology enables OEM partners to manage cloud-based wireless access points at the venue. As a result, managed service providers can compete positively with companies such as Aerohive and Meraki. By adding a small amount of code to their firmware, the access point can "call" the host service and c

The architecture of Aruba is similar to that of Cisco, but it only adjusts the access point so that it can make forwarding decisions in the branch. The Aruba Mobile Virtual Enterprise MOVE architecture allows branches to have up to 16 independent access points, one of which acts as the controller of the Branch's wireless network.

Cisco has a controller-based architecture that can centrally forward data-traffic is sent to a central controller via a Cisco hybrid remote edge access point (H-REAP). Aruba's architecture is similar to Cisco's, but it adjusts the access point to make forwarding decisions at branch offices. The Aruba Mobile Virtual Enterprise (move) architecture allows branch offices to have up to 16 stand-alone access points, one of which serves as a controller for branch office wireless networks.

AC + AP is a traditional enterprise wireless network architecture solution. AP is responsible for data forwarding. All control box management is completed on the AC side, and each node must have a controller. To solve the reliability problem, there are more than one controller. Two controllers may be redundant to ensure single point of failure. Obviously, this is an architecture that customers must do.
However, with the explosive growth of wireless devices and application traffic, the pressure o

Over the past few months, discussions have become increasingly enthusiastic about the evolution and deployment of 802.11ac. However, in consumer and enterprise-level markets, users' enthusiasm is not the same. 802.11ac has been widely supported in the consumer electronics industry. Apple, Samsung, HTC, Xiaomi, and many other mobile phone manufacturers have joined the ranks of 5G WiFi. However, for enterprise-level products, the promotion of 802.11ac seems to be slow.
However, with the user's dem
Wireless local Area network (small) in the past, is used to send and receive e-mail and browsing the web, the wireless LAN is usually used by radio frequency experts manual tools to troubleshoot network failures. However, as the data flow size and diversity become more and more significant, coupled with wireless LAN has become one of the main means of network access, wireless LAN fault repair methods have been rapid growth.
How WLAN management tools improve the ability of WLAN troubleshooting
What does 802.11ac mean for enterprise WLAN planning?
The IEEE 11ac Working Group finally completed six years of hard work. By the end of December 2013, the final version of the IEEE 802.11ac-2013 standard was approved. This high-throughput specification is expected to promote the data transmission rate of domestic Wireless LAN (WLAN) to reach a gigabit level, and the maximum speed is close to 7 Gbps. So what does the 11ac standard mean for enterprise wireless LAN planners?

. The only effective way to deal with this type of problem is to constantly measure it through real-time responses. Some wireless LAN vendors currently offer a "call time fair" algorithm that performs real-time RF testing and uses them to automatically adjust client transmission opportunities. For example, when aerohive dynamic Airtime scheduling is enabled, the transfer opportunity is allocated based on the amount of bandwidth that each client actua

Petr Jirovsk networks, research manager for Worldwide Networking Trackers, said, "in many regions, due to the healthy growth of 802.11ac popularity in the first quarter, global organizations are increasingly dependent on Enterprise WLAN ." He said, "however, the decline and the appearance of seasonal weakness in the US market due to the delay of projects have a great impact on global growth ."
