Shanghai Mobile Line Introduction:SDH transparent transmission line, high bandwidth transmission MSTP line, DDN digital data dedicated circuit (suitable for data transmission, various industry applications include: Chain agencies, medical industry, group intranet, social Security network, etc.)1.SDH is a transparent transmission line, currently use more than the majority of the use of 2M. 2M to 8M binding with a protocol converter.2. High-bandwidth tr

I. Differences between POS interface and GE Interface POs (SDH-based data packet) interface and Ge (Gigabit Ethernet) interface are deeply analyzed, this article makes a full comparison between the two technologies to achieve wide-area data stream transmission efficiency, fault detection capabilities, and economics. It is proposed that both POS interface and GE interface can be used for wide-area transmission, flexible options.Key words: GE, POs, tran

(Fan Zhongli Nanjing University of Posts and Telecommunications, Nanjing 210003) A standardized optical control plane is introduced in this paper. The optical control plane is decomposed into a few basic processes such as Neighbor Discovery, service discovery, Connection control and Topology/resource discovery. Different network organization and segmentation result in several different automatic configuration models: Soft persistent link model, user interface model and Peer-to-peer model. Final

The optical fiber access network is worth learning a lot. Here we mainly introduce the technical features of the optical fiber access network. The optical fiber access network refers to the access network with the optical fiber as the transmission medium in the access network. The Optical fiber access Network technology can be divided into two categories: AON and Active Optical Networks and PON and Passive Optical networks ). Active optical networks can be divided into

A few days ago, due to work needs, a DBLink should be established between an Oracle database and another Oralce database to Insert the data of one server into another machine. Oracle Server A: Sid: SDH, USERIDPW: NMNMOracle server B: Sid; gsgx, USERIDPW: gsgs create the following DBLink: from B A DB Link must be established between one Oracle database and another Oracle database a few days ago to Insert data from one server to another. Oracle Server A

. The main work of OIF in the intelligent optical network is to develop technical specifications for UNI and E-NNI interfaces, which has completed the UNI1.0R2 and E-NNI1.0 signaling part), UNI2.0 is in the testing process. OIFUNI1.0 defines a series of services, such as the signaling protocol used to request services, the transmission signaling information mechanism, and the automatic discovery process of auxiliary signaling. Currently, UNI1.0 is mainly used for SONET/

will continue to emerge, and the result will be a significant increase in the volume of business. It can be expected that in the next few years, the operator's network will be at least in the following directions. (1) The growth rate of data traffic will not be stopped. In order to adapt to this kind of demand, in the network structure, the IP/DWDM still is the mainstream. Due to the construction of the main cable in the previous few years, there is no shortage of optical fiber in the economi

high level, from old system (PDH) to new System (SDH). In the 76, the United States opened the world's first practical optical fiber communication system in Atlanta. The rate is 45mb/s and the relay distance is km. In 80, multimode optical fiber Communication System (140MB/S) was commercialized, and the field test of Single-mode optical fiber communication system was set up. In the 90, Single-mode optical fiber communication system entered the comm

automatically modified go.mod , and dependent version numbers may change. In the go.mod use exclude of excluded packages, cannot go get come down. Unlike before, the new version go get can be signed at the end and @ used to specify versions. It requires the warehouse must be in the format of the v1.2.0 tag, like v1.2 a few 0 is not possible, it must be a semantic, v prefixed version number. go get github.com/gorilla/mux # 匹配最新的一个 taggo get github.

. Before let's encrypt appears, you may buy a certificate, which is just a bunch of bytes. You will store the certificate in a file and configure your Web server to use it. With Let's encrypt, you'll be able to use their APIs to get certificates for free, and this process is done automatically after your server starts. Thankfully, all the hard work of talking to the API is done by others. We just need to install the plugin on it. There are two go libraries that enable let's encrypt support. I've

. WriteString, is a helper function that will want to write data to the output stream. Here is a slightly more complex example: Package Mainimport ("io" "net/http") Func Hello (w http. Responsewriter, R*http. Request) {io. WriteString (W,"Hello world!")}func Main () {mux:=http. Newservemux () Mux. Handlefunc ("/", hello) http. Listenandserve (": 8000", MUX)} I
