been noticed by traditional media with a keen sense of smell, who have long been aware of the changes in the audience of future television audiences. In fact, the traditional media in the television and radio in recent years has been very active in the field of digital television, network television and IPTV areas, the traditional media in the entry of the industry at the same time to China's current video site has brought opportunities.

Technical features based on PON technology
The PON system consists of optical circuit terminal (OLT), Optical Network Unit (ONU) and optical distribution network (ODN), which uses topological structures with dots to many points. Passive refers to all of the passive devices and optical fibers from Olt to ONU, and does not require any power source equipment. Pon All Optical Network has three networks in one business cap
With the advent of video on demand, network games and IPTV and other high bandwidth services, the user's demand for access bandwidth will increase further, the existing ADSL-oriented broadband access method has been difficult to meet the user's high bandwidth, two-way transmission capabilities and security requirements. Faced with this dilemma, telecom operators in various countries have turned their attention to FTTH, planning to use the optical fibe
strategy.
4. Management function
The existing system simple management function, not only makes the work efficiency greatly reduces, moreover cannot realize the operation: if does not have the ICP Virtual operator Management module, cannot solve the content source and the copyright question, thus realizes the ISP and the ICP Mutual win.

Beijing John Company's shine streaming media value-added application platform belongs to a set of telecom-level value-added service appli
convenience, but also help operators to enhance customer loyalty, attract new users, create new revenue stream. With the advent of the whole business integration era, including High-definition IPTV and other value-added multimedia services, will become an important source of revenue for operators, at the same time, will also be the operator to build a full range of business broadband network to put forward new requirements.

In fact, many people hope that the 2007 3G licences will be able to distribute digital trunking licences to some of the emerging operators, such as railcom, so that even if the 2008 Olympic Games cannot replace the digital trunking system in time, So can also make the domestic digital trunking communication standards can have more powerful support and European and American standards a high and low.
VDSL2 Technical Features
In recent years, with the rapid development of broadband Internet tech
service providers are building "fences". Some to prevent inappropriate access to some harmful information, such as the 1999 American online children's channel set up a walled garden, to prevent children from visiting some inappropriate sites. But the more important and common reason is business interests: Internet operators want to take user resources in their own hands, and guide users to access their own or partners ' resources to reduce or prevent access to competitors and resources that do
OMA Protocol WizardA concise tutorial to help you understand the OMA Protocol (i) (b)
Unlike the TR069 protocol, because OMA is designed to support data synchronization between different devices across networks, OMA's data transfer is not only built on the Internet session layer using HTTP transmission, OMA also supports wireless network WAP using WSP and Bluetooth network using OBEs for data transmission, etc. The transmission tools are different between different networks, but because of the
network system is made up as shown in the following diagram:
Ethernet switch can realize Port-vlan function autonomously, and connect with switch core through a trunk port. And switch core has a good vlan_tag classifier function. In addition, the WAN Terminal implements 8 hardware channel PVCs, and switch core can also classifier it well. In summary, you can realize the so-called port-mapping function, as long as a DSL access line, you can achieve in the home
For telecommunications devices such as Cisco, Nortel and Avaya, Tuesday is their bad day.
Tomorrow, Bill Gates will announce Microsoft's official foray into the communications equipment industry. The product that Microsoft brings is "unified communication". This is a platform to integrate all communication methods, such as: Voice, video, instant messaging and other information.
If the project succeeds, the software will accelerate the transfer of communications from proprietary devices to the
"Sina Science and Technology" August 28 morning News, China Telecom software store has been built, the test version of the software store will be the fastest in September online.
"The construction of the software store is almost over by the end of July, when all 133, 153 users can enjoy the same services as 189, including mobile phone mailboxes," said a senior Chinese telecom. ”
It is reported that China Telecom's software store will provide a unified cross-platform operating environment, has
functions. In particular, you can achieve this without changing your original Board, which is usually the case in other conventional exchange products. In addition, the investment protection capability is further improved by extending the time your Catalyst investment is used.
The Catalyst 4000 cabinet provides:
◆ Modular cabinets with three slots, one of which is reserved for the switch engine and two for the switch Module
◆ Two power supply racks that support redundancy (optional), load balan
With the development of China's routing technology, we have also promoted the improvement of the router protocol. Here we mainly introduce the experience of the Router Protocol. In the design of the IP network, the fault cannot be restored within less than 1 s. However, applications such as VoIP and IPTV require rapid Fault Detection and recovery. As a draft IETF standard, Bidirectional Forwarding Detection (BFD) provides a method for detecting the fo
, including the source/destination IP address, source/destination transport layer port number, and Protocol Number, and the underlying connection status. With these parameters, it is difficult to obtain sufficient business application information. Currently, P2P, VoIP, and IPTV applications are widely used. The traditional traffic detection technology cannot meet the needs of network traffic management.

In the SIP application, if a user is using the sip ua to enjoy a certain time-based service, such as watching a pay-as-you-go TV online and suddenly crashes, the server will not be able to know any information about the user's device crashes, the billing service continues.
This is obviously an unreasonable situation. The server must know the user's status in real time. In this case, the Presence Server may not be able to solve the problem. Because the user's sip ua sends a p
