. 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

sense, the DCN network is gradually becoming a comprehensive data network platform for multiple internal applications of telecom enterprises. However, the DCN network mentioned in this Article refers to the data communication network that transmits information in the control plane and management plane within the ASON network. The object it can compare is SDH management network DCN. For example, the SDH man

The urgent needs for high-speed data services and the future needs for video services provide unprecedented opportunities for broadband access, and various broadband access technologies are emerging. The ATM-based PON combines the capabilities that ATM is suitable for providing comprehensive broadband services. The upstream and downstream communication bandwidths can reach 155 Mbps. The bandwidth available to each user can be flexibly divided based on the protocol for sharing. At present, it mai

Wavelength 1300 nm, the effective transmission distance in the FDDI network and 100BASE-FX network of FDDI 62.5μm multimode fiber installed before 1990 is 220m, while in OM3 fiber can reach 260m, in connection length, it is inferior to the previous 10GBASE-LX4 specification, But its fiber-optic module has lower cost and lower power consumption than the 10GBASE-LX4 specification. 2.6) 10GBASE-ZR Several manufacturers proposed the transmission di

generated in the directory where nmon is located, and resource data is continuously written until the collection of 360 monitoring sites is completed-that is, monitoring is completed for one hour, the tester can continue to perform other operations without manual intervention. If you want to stop the monitoring, You need to query the process number through "# ps-Ef | grep nmon", and then kill the process to stop monitoring. The name of the nmon output file is server name_datetime. nmon. Convert

In the performance test, the tester program is started by the start. Sh script. Now, the user needs to press Ctrl-C to exit the program graceful without restarting the board. The problem is: Ctrl-C generates a signal SIGINT, but this signal is passed to the script process, not to the tester process. Therefore, there is a problem of signal transmission. The solution is as follows: 1. Add code to the script: Code: select all forward_sigint(){ # check out the tester's pid testerpid=$

I. Introduction to Nmon ToolsNmon is a free tool for analyzing AIX and Linux performance (primarily IBM developed for its own AIX operating system, but it can also be used on Linux operating systems), while Nmon_ Analyser is a tool for Nmon to convert Nmon generated reports into Excel reports for viewingThe Nmon tool can display all important performance optimization information on one screen and dynamically update it. It doesn't consume a lot of CPU,

This calls the Setvalueattime method to change the value of the gain node, as shown in the waveform change process. The gain node has a variety of different methods that allow the signal strength to arrive at a preset value in a different way, and the reader can consult the API of th

solution to broadband access, but the current large-scale implementation of FTTH is not economical. At the present stage is to realize FTTB/FTTC, the transmission technology can be used by active optical access (including PDH, ATM, SDH, GE/FE, etc.) mainly, but passive optical access (PON) began to be applied. For Ftth,pon, it will be the most economical and effective technical means. Second, passive optical network (PON) Compared with the active o

Installing Oracle on Linux often encounters situations where you need to use a bare device, and here's how to set up a bare device on red Hat 4. This document is installed on the basis of the installation of Oracle software and is installed with the option to install Oracle software only. The next step is to create a new database based on the bare device ... 1.

according to the tag information, such as reuse, oversubscribe of the business) and separate management and control of each data stream. A gsmp connection can carry a large amount of Ethernet user data, and store network data and data of Packet Ring services. In addition, each service can have independent traffic and QoS parameters, over-order level, and fault protection and recovery mechanisms. At present, GSMP is mainly applied in the following aspects: Aggregation and transmission of multipl
