How fast should the ADSL bandwidth rate go up, the downstream bandwidth rate and the uplink and downlink speed be? Many users have reported that the download rate of ADSL does not reach the nominal 5 12 K. After the network is connected through ADSL, a download speed indicator is displayed during download, the download speed shown above is generally about 50 KByte/s! This is a misunderstanding caused by unclear conversion relationships. First, we understand that Asymetric Digital Subscriber Loop

process dies and immediately switches the standby server, the switch time does not feel.Load Balancing:The upstream default is a poll-based load balancing method, in which each request is assigned to a different backend server in chronological order, and can be automatically rejected if the backend server is down. Another way is Ip_hash: Each request is allocated according to the hash result of the access IP, so that each visitor fixed access to a ba

From: http://my.oschina.net/wangbuke/blog/67450 Openerp 6.1 uses werkzeug as the Web service framework, and its performance is greatly improved compared with the previous cherrypy. However, werkzeug and cherrypy are not dedicated web servers. The common practice is to add an nginx, Apache, or other server before openerp. The following describes how to deploy openerp using nginx upstream. Prerequisites Assume that you have installed openerp and run

Ideas:Add a Source Vertex to join the edge of each row. The upper and lower bounds of each edge are the sum of the rows. Add a vertex and each column is connected to the edge of the vertex, the upper and lower bounds of the edge are the sum of the column. Then, each row is conne

What are the LTE downlink reference signals and upstream reference signals?In R9, the downlink defines four reference signals, respectively, for the cell-specific reference signal (C-RS), the user-specific reference signal (UE-RS, also known as Dm-rs), MBSFN reference signal, position reference signal (P-RS).In R10, the downlink defines five reference signals, namely, the cell-specific reference signal (C-RS), the user-specific reference signal (UE-RS
