than the protection channel provided by the SDH system for traffic signals such as GBE, which transmit large particles. From the above two aspects is not difficult to see, when the network of operators in the optical fiber resources are relatively tight, and the network has a large number of data service transmission requirements, the use of Metro DWDM system to build core optical network is a very ideal solution. It is noteworthy that in the transport interface layer, the transport access la

. In recent years, the new San over CWDM (coarse wavelength division multiplexing) solutions, such as the Ciena CN 2600 products, provide the best transmission performance, but also solve the high cost of DWDM, in the area of storage expansion has been widely used. SAN over IP solutions enable organizations to leverage their existing virtual private network (VPN) or public Internet delivery storage network business. Due to the high latency caused by

SFP Gigabit Ethernet ports can be installed with a wide range of SFP transceivers including CISCO1000BASE-SX, 1000BASE-LX, 1000BASE-BX, 1000base-zx, 100base-fx, 100base-lx10, 100BASE-BX and coarse-wavelength division multiplexing (CWDM) SFP transceivers.

enable Pprof. You can add a line of code import _ "Net/http/pprof" to your app and start your application server, pprof even if it's started. There is another way, when we are doing signalfx, in order to control the pprof externally, we attach some handlers, can be exposed with the routing settings, the code is as follows: Import "Github.com/gorilla/mux" import "Net/http/pprof" var handler *mux.

HandleFunc(pattern string, handler func(ResponseWriter, *Request)) { DefaultServeMux.HandleFunc(pattern, handler)} In the source code, this function is called and a method is called in it. func (mux *ServeMux) HandleFunc(pattern string, handler func(ResponseWriter, *Request)) { mux.Handle(pattern, HandlerFunc(handler))} This method is defined on the ServeMux structure, so what is this ServeMux specific? Now let's not take care of it, we follow

Gorilla also supports complex routing using regular pattern matching, schemes, methods, queries, headers values, and so on. Therefore, path and path parameters are not limited. In respo

Registration A registration pattern is followed by several packages in the class library such as net/http , database/sql , flag , and to a Lesse R extent log . It commonly involves a package scoped private map or struct which are mutated by a public function-a textbook singleton. Not being able to create a package scoped placeholder for this state would remove the si

Address:Http://localhost:8080/core.cssThe same get is index.html the content of this page,Which means that our registered route also matches the/CORE.CSS request. What is the problem?We have to write a route function ourselves to see how it matches the route:Let's take a look at the documentation for go: Look at the declaration of the Listenandserve function: stringerror If you want to write the route function, you have t

After the server opens a request comes in, the first call is Server.servehttp (rw responsewriter, req *request). func (mux *ServeMux) ServeHTTP(w ResponseWriter, r *Request) { ..... h, _ := mux.Handler(r) h.ServeHTTP(w, r)} The above function goes through Daoteng and fina

This kind of goroutine directly according to the logic of thinking to use Goroutine Performance optimization requires concurrency One scenario is this: a message needs to be sent to a group of users, and normal logic uses for _, user := range users { sendMessage(user)}//但是在考虑到性能问题的时候，我们就不会这样做，如果users的个数很大，比如有1000万个用户？我们就没必要将1000万个用户放在一个routine中运行处理，考虑将1000万用户分成1000份， //每份开一个goroutine，一个goroutin
