Carrier Broadband Technology One of the success of Ethernet is the infiltration in the field of telecommunications, not only the telecom operators for the needs of users to adapt to the needs of Ethernet transmission technology, while the telecommunications operators in the network using Ethernet technology. (Computer science) Ethernet Pass Through LANE: It's

I want to improve my programming technology now.

I want to improve my programming technology. A developer who is a PHP programmer is free to pick up outsourcing projects (or go to outsourcing companies) on his own ), I still want to go to Internet companies to learn and constantly improve their programming technologies. Now I want to improve my programming technology, a developer who is free to be a PHP programmer. If you want to connect to an outsourc

The development of the network puts forward new requirements for Optical Fiber No matter how the next generation network develops, it will surely reach three levels: the IP address world at the service layer, the light world at the transmission layer, and the Wireless World at the access layer. The next-generation transmission network requires a higher speed and a larger capacity. This is not a fiber optic network, but the development of high-speed backbone transmission also puts forward new req

　　Each system will have his life cycle, from life to death, through the three stages of adolescence, middle age and old age. 　　The management of complexity runs through the whole life cycle of the system, just like the natural choice of evolution, constantly optimizes the system and keeps the system alive. The initial stage of the system is to complete the construction of 0 to 1 to verify the business model or to do the smallest demo product. This is the time and cost of priority, and that is fa

DWDM/CWDM interface to work with optical transmission. The performance was constantly improved. It supports RPR networking technology, MPLS, and fast Spanning Tree Protocol, the integrated data, voice, and video services that can be managed and Intelligently Based on the IP platform will be gradually implemented, qoS, security, content distribution, MPLS, and other business features and solutions support w

technology does Google use? PageRank is the webpage level.Google has a founder named Larry Page. It is said that he applied for the PageRank patent, so he got Page Rank based on his name. There is also a very successful search engine company in China, called Baidu (http://www.baidu.com ). Baidu founder Li Yanhong said that as early as 1996, he applied for a patent named hyperchain analysis. PageRank's principle is the same as that of hyperchain a

I'm doing it myself, but I've been working on software development for many years, and when I look back on myself, I feel particularly interested in learning Java/dot. NET technology friends say something, I hope you can learn from our experience, how much inspiration (perhaps I say bad, you do not agree with me, but for the sake of my sincerity do not throw bricks AH). One. In China you must not because of learning

This article puts forward the intelligent firewall, this kind of firewall is smarter and smarter, overcomes the traditional firewall's "one tube to die, one puts on the chaos" condition, the revision above firewall's important assumption is "refuses to guarantee the security, releases also must guarantee the security". The new smart firewall changes the concept of "exit" to the concept of "gateway", and all packets passing through the "gateway" must be inspected by the firewall. In contrast to t

service ports of the aggregation Layer Nodes and reduce network costs. At present and in the future, the TDM business will remain the most important source of revenue for telecom operators, and there is still room for growth. When the business needs are dominated by TDM business, create a convergence layer for the Metro Transmission Network to use MSTP. If the existing SDH network still has a large amount of remaining capacity, it can meet the needs of future TDM business development, and when

China's router technology development is very rapid, at the same time the market demand is also very high, maybe a lot of people do not understand the technology of the proliferation of routers, there is no relationship, read this article you certainly have a lot of harvest, I hope this article can teach you more things. One of the important ways of GFW is the blocking of IP at the network layer. In fact, G

Traditional firewalls are usually based on access control List (ACL) packet filtering, located in the internal private network entrance, so also known as the "border firewall." In addition to the access control features, most firewall manufacturers now integrate other security technologies, such as NAT and VPN, virus protection, on their devices. I. Overview of the development of firewall technology Traditional firewalls are usually based on access

three kinds of RPR, manufacturers have introduced the corresponding products. The independent 2-layer RPR implementation scheme is mainly applicable to the access layer and the aggregation layer of IP metropolitan Area Network, and is the most mature solution at present. Some manufacturers combine multiprotocol label Switching (MPLS) technology, clock synchronization technology,
