== How to Publicize your Website ==
−
−
E-commerce is getting more and more popular. The rapid expansion and development has posed great threat to traditional business. The past ten years witness a boom of Chinese E-commerce. In Particular, some Chinese local e-commerce operators such as Taobao, JD, Dangdang, Tmall almost occupy the majority of market share. Their success is never a sheer coincidence but co-efforts of all staffs.
−
−
E-commerce, in short, is doing business online. Namely, website is just like your store, which is crucial to people's fist impression. That's why E-commerce operators always pay much attention to improving their website. A user-friendly, clear and featured website can easily catch visitors' eyeballs. Thus, step one, set up a stylish and practical website. Then, how to publicize your website should be put on the top agenda, which directly influences whether you can successfully get your website across and exposed to the public. Of course, there are many channels to publicize your website. For example, free channels such as social network, forum, blog and other payable channels such as online ads, exhibition, etc.
−
−
Now we have successfully established our website (http://www.optoroute.com.cn/) but my problem is how to effectively publicize our website. In my opinion, online marketing is a long process. It takes longer time to get your efforts paid off. Now I just ask your experts for help. Could you please give me some advices or share your experience. Your precious ideas and suggestions will be highly appreciated. Thanks so much.

== What Challengers Operators will Face when Digital Home is Befalling ==
−
−
The growth of internet-enabled devices and a maturing of networking technologies indicate the digital home is entering a new phase. But while operators believe the home offers important new service and revenue opportunities, considerable challenges remain. Operators are thus proceeding cautiously.
−
Here is a look at the status of the digital home in terms of:
−
•Services driving home networking
−
•Wireless and wireline home [http://www.optoroute.com.cn/ '''networking'''] technologies
−
•Challenges
−
−
Services driving home [http://www.optoroute.com.cn/ '''networking''']
−
−
IPTV and video delivery are key services that place significant demands on the home network in terms of bandwidth and reach. Typically the residential gateway that links the home to the broadband network, and the set-top box where video is consumed are located apart. Connecting the two has been a challenge for telcos. In contrast, cable operators (MSOs) have always networked video around the home. The MSOs’ challenge is adding voice and linking home devices such as PCs.
−
Now the telcos are meeting the next challenge: distributing video between multiple set-tops and screens in the home.
−
Other revenue-generating home services interesting service providers include:
−
•A contract to support a subscriber’s home [http://www.optoroute.com.cn/ '''networking''']
−
•E-health: remote monitoring a patient’s health
−
•Home security using video cameras
−
•Media content: enabling a user to grab home-stored content when on the move
−
•Smart meters and energy management
−
−
One development that operators cannot ignore is ‘over-the-top’ services. Users can get video from third parties directly over the internet. Such over-the-top services are a source of competition for operators and complicate home networking requirements in that users can buy and connect their own media players and internet-enabled TVs. Yet any connectivity issues and it is the operator that will get the service call.
−
However, over-the-top services are also an opportunity in that they can be integrated as part of the operator’s own offerings and delivered with quality of service (QoS).
−
−
Wireless and wireline home [http://www.optoroute.com.cn/ '''networking'''] technologies
−
−
Operators face a daunting choice of [http://www.optoroute.com.cn/ '''networking'''] technologies. Moreover, no one technology promises complete, reliable home coverage due to wireless signal fades or wiring that is not where it is needed.
−
−
As a result operators must use more than one [http://www.optoroute.com.cn/ '''networking'''] technology. Within wireline there are over half a dozen technology options available. And even for a particular wireline technology, power line for example, operators have multiple choices.
−
−
Wireless
−
•Wi-Fi is the technology of choice with residential gateway vendors now supporting the IEEE 802.11n standard which extends the data rate to beyond 100 megabits-per-second (Mbps). An example is Orange’s Livebox2 home gateway, launched in June 2009.
−
•The second wireless option is femtocells, that is now part of the define features of the Home Gateway Initiative’s next-generation (Release 3) platform, planned for 2010. Mass deployment of femtocells is still to happen and will only serve handsets and consumer devices that are 3G-enabled.
−
−
Wireline
−
•If new wiring of a home is possible, operators can use Ethernet Category-5 cabling, or plastic optical fibre (POF) which is flexible and thin.
−
•More commonly existing home wiring like coaxial cable, electrical wiring (powerline) or telephone wiring is used. Operators have adopted HomePNA which supports phone wiring; the Multimedia over Coax Alliance (MoCA) that uses coaxial cabling; and the HomePlug Powerline Alliance’s HomePlug AV, a powerline technology that uses a home’s power wiring over which data is transmitted.
−
•Gigabit home networking (G.hn) is a new standard being developed by the International Telecommunication Union. Set to appear in products in 2010, the standard can work over three wireline media: phone, coax and powerline. AT&T, BT and NTT are backing G.hn though analysts question its likely impact overall. Indeed one operator says the emerging standard could further fragment the market.
−
−
Challenges
−
•Building a home network is complex due to the many technologies and protocols involved.
−
•Users have an expectation that operators will solve their networking issues yet operators only own and are interested in their own home equipment: the gateway and set-top box. Operators risk getting calls from frustrated users that have deployed a variety of consumer devices. Such calls impact the operators’ bottom line.
−
•Effective tools and protocols for home [http://www.optoroute.com.cn/ '''networking'''] monitoring and management is a must for the operators. The Broadband Forum’s TR-069 and the Universal Plug and Play (UPnP) diagnostic and QoS software protocols continue to evolve but so far only a fraction of their potential is being used.
−
Operators understandably are proceeding with care as they cross the home's front door to ensure their offerings are simple and reliable. Otherwise any revenue-potential home [http://www.optoroute.com.cn/ '''networking'''] promises as well as a long-term relationship with the subscriber will be lost.

== How is Optical Switching Technology use in the Communication Network ==
−
−
[http://www.optooute.om.cn/ '''Fiber optic'''] network, as synonymous with high-speed and effective in the communication system has been for a large scaled deployed and applied. However, the transparent, high survivability of optical communication network is a goal of broadband communication network. Optical switching technology as an important foundation for all-optical communication network technology, its development and application will greatly affect the development direction of future optical communication networks.
−
−
Advantage of [http://www.optooute.om.cn/ optical fiber] communication is the huge capacity and strong anti-jamming capability, superior performance of which has already been confirmed, and in modern communication systems gradually replace the electronic circuits in the past as the main components of the communication network, becoming an important component of modern communication.

All-[http://www.optoroute.com.cn/ optical network switching technology]
−
−
To realize the all optical network switching, the first is to use the circuit switch based optical add-drop multiplexing (OADM) and OXC (optical cross connect) technology to achieve wavelength switching, and then further realization of optical packed switching.
−
−
Wavelength switching is based on wavelength in units of optical circuit switched domain, wavelength switching optical signals to provide end-to-end routing and wavelength assignment channel. Wavelength switching key is to use the corresponding network node equipment, optical add-drop multiplexing optical cross-connect. Optical add-drop multiplexing the working principle is based on all-optical network nodes drop and insert the required wavelength path. Its main constituent elements of the multiplexer reconciliation multiplexer, as well as optical switches and tunable harmonic, etc.. Optical add-drop multiplexing of the working principle and the synchronous digital hierarchy (SDH) multiplexer separate interpolation function is similar, but in the time domain, while the other is acting in the optical domain. The optical cross-connect and the synchronous digital system digital cross-connect (DXC) similar effect, but to achieve the cross-connection to the passage in the wavelength at which the optical network node.
−
−
Optical wavelength to exchange essentially took office contingent is not efficient optical switching, connection-oriented attribute it established wavelength channel re-distribution to achieve maximum utilization efficiency can not be achieved, even if the communication is idle. Optical packet switching can be implemented with a minimum switching granularity multiplexing of bandwidth resources, improve the communication efficiency of the optical network. Optical packet switching is generally light and transparent packet-switched (OTPS), optical burst switching (OBS) and optical label switching (OMPLS). The optical the transparent packet switching characteristics is the packet length is fixed, the use of synchronous switching manner, the need for all input packets are synchronized in time, thus increasing the technical difficulty and increase the use of cost. The transmission optical burst the use of a variable-length packet data transfer header control information and separated in time and space, to overcome the shortcomings of the synchronization time, but it is possible to generate the packet loss problem. Optical label switching is carried out to add a tag in the IP packet in the core network access re-packet, and the routing method according to the tag inside the core network.
−
−
Although [http://www.optoroute.com.cn/ '''optical switching'''] communication Occasion require a higher (generally more than 10Gb / s) is more suitable for lower transmission costs and greater system capacity can be achieved; via digital transmission rate when the system requirements require a lower transmission rate (2.5Gb / s or less), the connection configuration more flexible access may be more appropriate to use the old-fashioned way of photoelectric conversion. Therefore, the practical application of the current should be selected according to the application scenarios appropriate system deployment.
−
−
With the future communication network technology development and all-optical network, [http://www.optoroute.com.cn/ '''optical switching''']technology will be more innovative and more efficient ways for communication network photochemical contribute to become an important part of social development and people's lives.
