1 Instable broadband service
It is approaching the end of the year. Usually, at the same time, all local units will begin the year-end summary of 2015. The project will be accepted and accepted, and assessment and evaluation will begin. The 2016 budget will also be added up. Whether it is a summary or a budget, the next step is inevitable planning of the strategy and business plan. What will happen next year? What are you doing? Total total.
Over the past decade or so, there has been a curse that has been plagued by cable operators. That is broadband.
Do you want to engage in broadband? No qualification, no export, how to fight? Do not earn money, how to make money? These many problems have been hovering in the hearts of cable TV people.
In the middle of the dispute with the ATM/IP, the access network technology of the mining industry has been discussed for a long time. This doesn't mean that EOC and CM are just a little bit different. Now under the background of the optical network city, it is necessary to increase the bandwidth of the home, that is, the upgrading problem of 100M, is the upgrade of CM2.0 to CM3.0, or the downward movement of the EOC optical node, or the direct optical fiber entering the home What? Where does the cost of upgrading increase come from? . As if we could never see the end of the controversy. Although the phrase “without optimal technology and only the most adaptable technologies” can guide us in “doing a good job”, it is really necessary to spend real money and silver and begin to implement it.
Therefore, more than ten years have passed and the leadership of the radio and television has changed several times. However, today, there are only a few broadband subscribers with more than one million broadband subscribers. The total number of subscribers is less than 15 million. The penetration rate exceeds 20%. In contrast, IPTV users in several provinces such as Sichuan, Jiangsu, Hebei, and Xinjiang have even reached more than one-third of the cable TV users. The cable TV broadband users are only less than a third of IPTV. Should we mourn or sigh?
Why is it so hard? Short talk with everyone and take a look:
2 again to review the next three network integration promotion program
Notice of the General Office of the State Council on Printing and Distributing the Tri-Network Convergence Promotion Plan this year: Guoban Fat [2015] No. 65
Promoting triple play is a major decision made by the Party Central Committee and the State Council.
In recent years, all regions and relevant departments have faithfully implemented [Who said this, of course, the General Administration of Administration, the Ministry of Industry and Information Technology, the local bureaus, the local units, and the so-called related units, you certainly know]
The State Council's work plan on promoting the integration of the three networks and the pilot program, the pilot phase of the various tasks have been basically completed [said the first stage, the second stage].
On the basis of summing up the pilot experience, we will accelerate the promotion of triple play across the country, promote the interconnection and sharing of information network infrastructure, and share resources. There is a need for further progress, which will help promote consumption upgrades, industrial transformation, and improvement of people's livelihood.
All localities and relevant departments must fully understand the importance of comprehensively advancing the integration of the three networks, effectively strengthen organizational leadership, implement work responsibilities, improve the working mechanism, and carry out work in a down-to-earth manner to ensure that the goals and tasks of the promotion phase are completed. Well, we all know that is the point we need to make, you say it is not.
The Office of the Coordination Committee of the State Council's Triple Play Integration Office will work together with relevant departments to strengthen guidance, coordination, follow-up and supervision [how to track, how to implement, of course, issue documents], and constantly improve relevant policies to solve problems encountered in the promotion work in a timely manner. All relevant departments should further strengthen coordination and cooperation and form a joint force to jointly advance various tasks. [This is a paragraph you think is empty talk or cliché, of course it makes sense]
[task]
1. To promote the two-way access and licensing of radio and television and telecommunications services nationwide. (for the record)
2. Accelerate the interface between the IPTV integration broadcast control platform and the IPTV transmission system. (This is mentioned every year. If you don't understand it, you don't understand it. It's obviously not, there are some benefits, and there are some drivers for not doing it.)
Radio and television and telecommunication services enter in both directions. The fact is that IPTV/OTT is now almost three-way with cable network users. The content is almost homogenous, and cable broadband has lost many opportunities because of missed opportunities: low price, poor word-of-mouth (game users Do not dare to access), how to give up, obviously not possible.
【Origin】
After many years of accumulation of telecommunications companies, IDC has accumulated to a certain extent. It is difficult to exceed the high threshold of broadband access currently. It is as if fixed lines are currently fixed to the cable, and it is difficult to go to heaven, whether it is export settlement, content resources, or IP addresses. The construction of the backbone network needs to work hard to catch up.
3 helplessness on top of broadband design
Let's start by taking a look at the online article: "Comprehensive Analysis of the Internet Backbone"
The Internet Backbone Provider (IBP) mainly refers to the Internet Service Provider (ISP), a national Internet service provider with a backbone network, including the first-tier backbone network (Tier1 ISP). ) and second-tier backbone (Tier2 ISP). These backbone networks are approved by the state and can be directly connected to the Internet. Other ISPs with access functions want to go abroad and have to go through the backbone network.
The way in which the international common interconnection method connects and exchanges information is called the interconnection method between the Internet. According to the way in which the two parties exchange information, the Internet can be divided into two types: one is Peering, and the other is Transit.
The rules or methods for the two sides to pay the fees are called inter-network interconnection settlement mode. There are roughly two types of internet internet settlement models: one is the free settlement mode, which is "caller keeps all income" (SenderKeepsAll, SKA) or "Bill and Keep" (Bill and Keep); the other is the settlement mode (Settlement) ).
Most traffic on the Internet is transmitted between users and websites. In general, the traffic from the user to the website is relatively small (that is, the request for the website to transmit the content), and the traffic from the website to the user is very large (the content provided by the website). This means that in many cases, the initiator of the traffic exchange uses only a very small part of the total traffic, while the website is only providing services but is the source of most of the traffic. Internet operators cannot provide a unified information service. The basic unit of network transmission information is the so-called packet. Operators can't accurately identify who is the beneficiary from the packets they transmit. Therefore, it is impossible to determine the transmitted data. The value cannot satisfy the preconditions for adopting the traditional telecommunication network settlement system. In addition, most of the applications on the Internet are asymmetric.
1. Peering
According to the SKA agreement, the peers need not settle. The premise of the existence of peer-to-peer interconnection is that the interconnection has equal interests for both parties, which can save the cumbersome traffic records and save costs. Peer-to-peer interconnected parties must meet certain peer-to-peer interconnection conditions. To measure the scale of the network, it is necessary to examine such factors as geographic coverage, capacity, traffic volume, and number of users. The two sides reached a peer-to-peer interconnection agreement on the basis of a balance of interests, which is a completely mutually beneficial business behavior.
Peer-to-peer interconnections can be further divided into two types based on the physical connection method. One is public peering (Public Peering) and the other is private peering (Private Peering). The former refers to the peer-to-peer interconnection relationship among multiple networks. Each backbone operator signs and complies with multilateral agreements. This type of interconnection generally takes place at the public exchange point. The latter refers to the peer-to-peer interconnection relationship between the two networks. The two backbone operators sign and comply with bilateral agreements. This interconnection can be performed either at the public switching point or by the two operators directly connected through their own circuits.
2. Asymmetric interconnection (Transit)
In this mode, a backbone network pays for the interconnection to another backbone network, and the strengths of the two parties are very different. On the one hand, the small ISP cannot and does not need to establish a full mesh network connection. On the other hand, the large ISP has enough routes to meet the requirements. The needs of small ISPs are commonly seen between upper-level ISPs and lower-level ISPs, and between foreign and domestic Internets. The party providing the service is obliged to open all routes to the other party, that is, the service is completely penetrated, and can enter other backbone networks through the transferor. This is a typical "provider-user" business relationship in which a user (usually a smaller network operator) purchases services by paying a provider to a provider (usually a larger network operator). Access to other Internet.
3. Partial peering (Partial Peering)
Part of peer-to-peer interconnection refers to that one ISP uses only part of its own network to establish peer-to-peer interconnection with another ISP. The two parties only need to have considerable network scale and strength in the open-route geographical location area. Applicable to cases where one ISP has established a connection in another area and needs to establish a connection in a specific area again. It often exists between the second-level backbone networks or between the second-level backbone network and the first-level backbone network. The application is flexible. . This approach is more prevalent in South America and Europe.
4. Paid Peering
Since there are many different types of ISPs in Europe, there is often the use of settlement-based peer-to-peer interconnections, namely the bilateral settlement model. This model adopts the common assumption of the physical connection cost in settlement, but the difference in the traffic between the two networks needs to be measured through the agreement, and at the same time, the pricing is paid by one party to the other party according to the flow difference. The two parties to the interconnection are quasi-provider-user relationships, and the networks are customer relationships. The pay-penetration settlement model refers to the asymmetrically interconnected settlement model. The rate between two ISPs depends on the size of the two parties (measured standards include the number of users, traffic, backbone capacity, geographic coverage, and content sites. The quantity, etc., is lower than the rate of asymmetric interconnection, and the interconnection fee is mainly used for cost compensation to the large network (rather than forming a large net profit).
5. Partial Transit (Partial Transit)
Partially asymmetrical interconnection refers to the provision of asymmetrical interconnected ISPs that only forward traffic destined for a particular direction. This type of connection is mainly used in South America. The formulation of its rates also follows the common asymmetrical interconnection model. The two parties that are suitable for establishing interconnections have large gaps in network size, traffic, etc. The ISP providing the service does not open all the routes or the ISPs that have received the service have established some connections but only need some special switching. You are free to choose the route structure that suits you.
Well, we can now summarize the interconnection model of the Internet backbone network. In the Internet, there are multiple modes of interconnection and interconnection between the Internet backbone networks. We can distinguish them by four different dimensions:
(1) According to the different physical connection methods, they can be divided into direct interconnection and interconnection through switching centers;
(2) According to the way the two parties exchange information, they can be divided into non-penetrating interconnections and penetration interconnections;
(3) According to the different settlement modes, it can be divided into paid interconnection and no-exclusive interconnection;
(4) According to the degree of openness of the route, it can be divided into the interconnection of one side to the other side to open the partial route and the interconnection of one side to the other side to open all the routes.
What about China? At present, China has nine backbone networks:
China Public Computer Internet (CHINANET)
China Science and Technology Network (CSTNET)
China Education and Research Network (CERNET)
China Jinqiao Information Network (CHINAGBN)
China Unicom Internet (UNINET)
China Netcom Public Internet (CNCNET)
China Mobile Internet (CMNET)
China International Economic and Trade Internet (CIETNET)
China Great Wall Internet (CGWNET)
Take China Telecom as an example, the core layer of China Telecom's CHINANET Backbone consists of the core nodes of eight cities including Beijing, Shanghai, Guangzhou, Shenyang, Nanjing, Wuhan, Chengdu and Xi'an. The core nodes are not fully meshed. With the three-center structure centered on Beijing, Shanghai, and Guangzhou, the other core nodes are connected to these three centers with at least two high-speed ATM links. In addition, the provinces also established secondary nodes.
After reading this, everyone's heart has been counted, people do not have a broadband game on the top-level design, how to do broadband cable?
4 Breakups: TV + Broadband
From a large strategic perspective, the experts have also elaborated on the things that the cable companies have to do:
1. Implement radio and television +, develop broadband radio and television strategy, practice media integration
Focusing on innovation-driven innovation and implementation of “radio and television plus” actions, we will continue to develop broadband radio and television strategies, upgrade and renovate radio and television networks, and focus on the coordinated development of television and broadband, and a balanced revenue structure (relying on subscription fees and floor-to-ceiling costs). Higher corporate risks, promoting the integration of traditional media and emerging media, making the construction of broadcasting and TV network a new type of network with the characteristics of propaganda culture and information services, giving full play to the important basic information network in which the Guangzhou Power Grid is reliable, and comprehensively enhancing the integration of broadcasting and TV. Media service capabilities and security capabilities.
2. Insist on innovation and development, speed up reforms, and promote the development of radio and television networks
It will fully understand the new normal, adapt to the new normal, continue to adhere to innovation and development, promote new development under the new normal, and actively expand the user base for enterprise restructuring and network integration. Applying the invisible rights of cultural media will continue to accelerate the pace of institutional and institutional reforms and release the internal With vitality and employee enthusiasm, we will explore the introduction of social capital forces and investment and financing cooperation models to cultivate new development drivers and focus on improving the quality and efficiency of corporate development.
The above seems to be correct nonsense. In addition to surfing the Internet, broadband users are currently nothing more than video, downloads, games, e-commerce, social networking, and search. On the specific issue we proposed (in parallel) four steps:
1, on the export to find ways to connect with telecommunications, China Unicom, and the surrounding wired network connection (NAT to BGP conversion).
2. Cache and broadband CDN construction, leaving traffic in the network (main video traffic), when the export to a certain point, the cost is too high, must be established through the flow model, from the export buyout mode to traffic management mode. (Top content of TOP5-10 video site)
3, mirror mirrored partners (especially the content of the local province)
4, speed up the game and other special content (solve the short board) (TOP15 hot game site)
In the end, of course, there is a point. This requires a lot of IP talent. Are you ready?
Reasons all understand, saying that "Tao" is easy and difficult to do. The key is to be firm and not to sway. In the era of Internet+, time will not give you a chance. Let's look at the time again on December 31, 2016.
