aps equalizer

A few days ago the user called to say that the administrative building wireless network is not good use, all the APS are bright red! Very strange, because the day before the use is normal, how all the bad use it? Rushed to the user site login WLC, found on the WLC a lot less APS, and these APs are 1131, the other models of 1142, 1602 are working properly, is it r

Hadoop EqualizerWhile Hadoop is running, its datanode blocks become increasingly unbalanced, and unbalanced clusters can cause some datanode to be relatively busy.The Hadoop equalizer is a daemon. It re-allocates blocks, moving blocks from busy datanode to relatively idle datanode. At the same time, adhere to the replica policy, the replicas scattered to different racks, to reduce the data corruption rate.Cluster equalization Criteria: the utilization

of depth. 1. aperture value... the larger the aperture, the deeper the depth of the scene... the deeper the depth of the field. 2. Focal CIDR... the same as the aperture in large hours... the wider the focal CIDR... the deeper the depth of depth... the less the depth of depth... 3. The distance between the camera and the object to be taken... the closer the distance... the lighter the depth of field... the deeper the opposite. Remember the above three reasons Let's look at the

The rapid development of wireless network technology has led to the wireless AP has gradually integrated into our life and inseparable. Wireless APs are mainly used in enterprises, shopping malls supermarkets, hotel restaurants, school factories, exhibition and other places to build WLAN and provide WiFi coverage.Many end users feel that using wireless APs to build a commercial WiFi user experience is not g

priority is selected. Benefits: You can allocate requests based on the capabilities of the server. Sed the shortest expected delay. In fact, SED is similar to WLC, except that the number of inactive connections is not considered. The algorithm is: (Active connection number +1) *256÷ weight, the same computed value of a small server priority is selected. NQ never line up. An improved SED algorithm. We think about what circumstances can "never queue", that is, the number of connections to the ser

Sharding:-------------------------------------------------Sharding:------Sh.status () can see the status of the cluster: Shard summary information, database summary information, collection summary information.The primary shard differs from the primary node in the replica set. The primary shard refers to the entire replica set that makes up the Shard, whereas the primary node in the replica set refers to a single server that can handle write req

With the Ethernet network, multiple wireless APs can be connected together to set up a wireless roaming network to enable users to roam the entire network wirelessly. When a user moves from one location to another, and a wireless access point becomes weak or the access point is congested because of traffic, it can connect to the new access point without interrupting the connection to the network, which is very similar to the mobile phone that is used

The algorithm is: (the number of active connections +1) *256÷ weight, the same calculated value of the small server priority is selected.8. NQ never queue . Improved SED algorithm. We think about the situation in order to "never queue", that is, the number of connections to the server is 0, then if there is a server connection number of 0,

We think about what circumstances can "never queue", that is, the number of connections to the server is 0, then if there is a server connection number of 0, the equalizer directly forwarded the request to it, without having to go through the SED calculation. 9, LBLC based on the least local connection.
