The packet transmission network (PTN) technology, which combines the advantages of packet technology and
synchronous digital system (SDH) technology, is more suitable for multi-service bearer and exchange, and satisfi es
fl exible network scheduling and multi-service transmission. It can provide network protection function. PTN technical
characteristics determine that he can better use the existing network, can provide more with the current network
interface. This paper analyzes the characteristics of PTN technology and the existing networking methods, and
proposes a network improvement method of IP + PON + PTN.

The emergence of cloud computing has brought great changes to the internet. The changes occur due to the eff ective
use of idle resources and more importantly, it is the results of Google, Amazon and other major internet companies
to change the desktop form for the PC core software. Firstly, cloud computing can be the development of Distributed
Computing, Parallel Computing, and Grid Computing. It can make full use of the Internet's computing resources to
provide users with on-demand services. Cloud computing, although from the Internet, but in a long run, we can notice
that there is no one type of business other than telecom operators that could be more conducive to develop a complete
chain from user end to the internet and to computing. With the introduction of 3G and reorganization of China's
telecom operators, operators can build a highly integrated cloud computing chain and its user base and infrastructure
construction become obvious advantages for continuous development. As to how to develop the telecom operators
and how to establish their own specialty and improvement, is an urgent problem to be solved. Based on the current
situation of cloud computing and cloud computing of telecom operators in China, this paper analyzes the advantages
and disadvantages of telecom operators 'development of cloud computing by studying the strategy and development
of telecom operators' cloud computing in China and abroad. This paper also discuss the insights and proposals to the
changes, countermeasure, and strategies towards cloud computing development by telecom operators, in the hope of
contributing to the development of China’s cloud computing industry.

The development of network management software is gradually mature with the development of network. The
software is diff erent to distinguish due to the wide range of network management software in the current market. This
paper aims to help readers to identify the suitable network management software for their daily use. In this article,
we gather information from the investigation of network management system used by enterprises and from network
inquiries. The article discusses some issues related to the network management software including the commonly used
software, the application of the software, the use of the software base on diff erent users, the characteristics of diff erent
software, the consideration of specifi c software, as well as development trend.

Computer network refers to the multi-computer with independent functions and their external devices, which are
connected by communication lines. The resources are realized under the management and coordination of network
operating system, network management software and network communication protocol. Sharing and information
transfer of computer systems. The topic of this computer network is based on the C / S time synchronization server
implementation. Time server is in the LAN as a unifi ed time to publish the server, which uses the computer network
to pass the time information to the user. Refer to the existing time server principle and eff ect to achieve a time server
and client. The server opens the specifi ed port release time to the network, and the other client obtains the time from
the network and synchronizes the local time. This design is based on Visual Studio 2010 as the development platform,
to discuss the design of the view of the process from these 5 aspects: the topic background, program demonstration,
process discussion, analysis of the results and conclusions.

With the development and implementation of concepts such as triple play, mobile Internet, Internet of things, cloud
computing and intelligent city, China is launching the 'broadband China' national development strategy. This will
further accelerate the development of broadband in China, and further promote the related industries, especially optical
communications technology, systems and devices and the rapid development of electronic information industry, while
promoting the metro and trunk optical transport network construction and expansion, and FTTx optical network
construction and bandwidth speed. Under the guidance and promotion of the strategy of 'broadband China', China is
entering the new period of broadband construction. The three major telecom operators have further accelerated the
construction of FTTx optical access network. In order to meet the needs of this development, ultra-high-speed, large
capacity, ultra-long distance optical transport network technology research will accelerate; fi ber access technology will
be the next generation of broadband optical access network NG PON technology development and evolution. This
paper mainly discusses the development history and development status of optical fi ber communication technology,
the technology used and its future development trend
