This article describes the development and basic concepts, principles, and high-speed SONET/SDH Network Connections of virtual routers. I believe this article will help you. Recently, some new breakthroughs in IP backbone network equipment have paved the way for the future implementation of new Internet services. Vro is a new technology that makes some new Internet services possible. With these new services, you can control network performance, Intern

Write a corresponding method by PAGE, except that the database table name and field name are different, which is too unprofessional. As a result, when the database table name and field name are proposed as parameters, the method is called and then input, so that the method portability in the class is much better. Class Code : /// /// Bind data by PAGE/// /// /// /// Public datatable showpagesea (INT pageindex, int pagesize, string datatable, string ID){String SQL = "select top" + pagesize + "* f

transmission links based on SDH or PDH is wider and wider, and has reached the village level in some areas. A large number of underground optical cables provide a large number of E1 links, which are cheap and available everywhere.All of these make the DDN Network Based on PCM devices a good choice, providing a solution for access to large users in both the township level 4 network and the urban level 3 network. In this solution, there is no need for

, mappers launched the latest MP 9710 multi-service access platform MSAP ). The primary goal of the new MP 9710 MSAP is to extend the ATM network so that operators can provide flexible and diverse data leased line services at a low cost, achieve the goal of rapid investment recovery and continuous profitability of the network. Connection between leased lines and ATM services Financial users account for the largest proportion of leased line business profits. Achieving 2 m to outlets is an importa

A friend of the author works in China Telecom and is mainly responsible for the fiber optic business of China tietong. At a recent meeting, he told me about several failures encountered during Optical Fiber maintenance. The author selects two of the most representative introductions for readers, I hope you will learn from the article and reflect on the whole process of solving the problem. Fault 1: multiplexing segment codes caused by SDH and their ha

I summarized the error before creating an ASM Disk: http://blog.csdn.net/rhys_oracle/article/details/17029333 This is the case today. As follows: When you use openfiler to map to a local disk through iSCSI, the following error occurs when you create the entire disk as ASM: [[emailprotected] iscsi]# /etc/init.d/oracleasm createdisk VOL1 /dev/sdhMarking disk "VOL1" as an ASM disk: [FAILED][[emailprotected] iscsi]# tail -5 /var/log/oracleasm Cleaning any stale ASM disks...Scanning system for A

functions of IP networks, this greatly improves the QoS, routing, signaling, and other performance of the IP network communication, and achieves or approaches the statistical reuse of fixed-length group switching ATM. It is simpler, more efficient, cheaper, and more suitable than ATM. IETF is also focusing on new grouping management techniques to achieve QoS selection. The "tunneling technology" is being studied to achieve one-way link broadband transmission. In addition, how to select an IP ne

At present, the ASON routing protocol is widely used. So I have studied the comprehensive description of the OSPF-Based ASON routing protocol. I will share it with you here, hoping it will be useful to you. With the development of related technologies in the information field, especially the powerful driving force of Internet on the Growth of data services, optical networks are required to adjust the logical topology of networks in real time and dynamically to achieve optimal resource utilizatio

The ATM technology was proposed by ITU-T in late 1980s s to support broadband multimedia services for telecommunication networks. After nearly ten years of research, by the middle of 1990s, the ATM technology has been basically mature, and the relevant international standards developed by the ITU-T and ATM Forum are also basically complete, in addition, multiple telecom equipment manufacturers and computer network equipment manufacturers have launched commercial ATM devices. Since then, the cons

Fiber access network devices are still commonly used. So I have studied the functions of the next-generation Metro optical access network devices. I would like to share these functions with you here. I hope they will be useful to you. The ADM622 product series provides carrier-level devices with low costs and flexible services. The PM5337ADM622 and PM5338 ADM 622 PDH Optical Fiber access devices of PMC-sield are used for the remote deployment of SONET/SDH
