In the technical life cycle, there are five types of consumers and corresponding, including two types of consumers in the early market: innovators and early adopters. These people are innovative, hoping to create interests and competitive advantages through innovation and breakthroughs. Then there are two types of consumers: pragmators and cautious people. These people are cautious. The last type of consumers are extreme conserves, this group of people's attitude towards high-tech and criticism, is the lague of the market.
At present, in 10 Gigabit Ethernet users, it is basically used by the technical vision and the new technologies that are easy to recipient, such as the high school government, research unit, and technical content. Now, there has been a successful use of 10 Gigabit Ethernet applications, such as the Ottawa Telecom Corporation (Telecom Ottawa), has established a metropolitan area with 150 mile fiber, using Netjie 10 Gigabit Ethernet equipment.
10 Gigabit Ethernet should enter the mainstream market from the early market, and must enter the practical phase as soon as possible, including a greater degree of compatibility, higher cost performance, and more new products and competitors, and more important It is a further popularization of broadband services to contribute to the actual needs of bandwidth, which depends on researchers, practitioners, managers, operators and consumers.
10 Gigabit Ethernet faces Gigabit Comparative Advantages
Since everyone is trying to analyze the development prospects of 10 Gigabit Ethernet from the application perspective, then we may wish to comment from the application perspective. It is also, the focus of corporate managers consider the construction of reasonable, in line with the technology development trend, rather than 10 Gigabit Ethernet modules themselves, users care about how to apply 10 Gigabit Ethernet in the network, rather than 10 Gigabit Ethernet The internal structure of the module.
Everyone will ask what is the advantage of 10 Gigabit Ethernet compared to Gigabit Ethernet?
The answer is: In the past, several Gigabit bundles needed to meet the high bandwidth required to meet the interconnection of the switch, and there is a waste of fiber resources, and now you can use 10 Gigabit interconnections, or even 4 10G bundles. Reaching 40 g of broadband levels.
After the more and more servers are changed to use Gigabit Ethernet as a condensed technology, the backbone bandwidth of the data center or group network increases, with a Gigabit or Gigabit bundle as a platform, it is no longer able to meet the needs, upgrade to 10 Gigabit Ethernet The network will have a relatively advantage in service quality and cost. In addition to these two points, because 10 Gigabit Ethernet technology has extension of Ethernet technology in the past, there will be a large amount of space in the existing network market, especially broadband demand, and its The advantage can also be reflected in the following aspects:
◆ In the large construction of the broadband metropolitan area, the access layer will have more and more gigabit or Gigabit Ethernet to connect to the aggregation layer of the metropolitan area, and the aggregate layer will also become more and more gigabit. Ethernet is connected to the backbone of the metropolitan area, which makes a broadband demand like 10 gigably or 10 gigabonds in the aggregate and backbone layer in the metropolitan area network.
◆ Because Ethernet and SONET / SDH (POS) have considerable price advantage in long-term development, 10,000 Gigabit Ethernet support seamless connection with the SONET / SDH infrastructure, which has always been SONET / SDH monopoly. A new competitor has appeared in the WAN market.
◆ When Ethernet technology is used as a storage network platform, the delay and high bandwidth are critical components, so the Wan Zhao Ethernet can be used to archite an Ethernet platform storage network, which is an emerging application, not only You can meet the high-speed interconnection of the storage device, or you can achieve backup and disaster responses of storage devices. From cost, 10 Gigabit Ethernet can get better in this emerging application.
In addition, 10 Gigabit Ethernet can also look for more application spaces in other multimedia applications, such as VOD video on demand or multimedia production.
10 Gigabit Ethernet rationally protects the original investment
The successful promotion of a new technology, in addition to the major breakthroughs of the technology itself, while compatible with the original application environment, it can be favored by the user's original investment, and 10 Gigabit Ethernet is already very good in this regard. 10 Gigabit Ethernet in technology basically in the past Ethernet, fast Ethernet and Gigabit Ethernet technology, so in the user's penetration, the convenience of use, the interoperability and simpleness of the network have great Introducing advantages, when upgrading to 10 Gigabit Ethernet solutions, users don't need to worry about whether existing programs or services will be affected, so the risks of the upgrade are very low, which can be upgraded from the past Ethernet all the way to Gigabit The Ethernet is proved, and it will be a significant advantage in the future.
In the enterprise network, 10 Gigabit Ethernet can best connect to the enterprise network backbone router, which greatly simplifies the network topology and improves network performance. As the application server is gradually adopting a copper Gigabit Ethernet network card, the data center switches that aggregate these servers must be connected to the enterprise backbone router. Today, the company will also use the Gigabit Ethernet to interconnect the park network, thereby reducing the rent of the fiber to save money. In the next few years, 10 Gigabit Ethernet will gradually use the interconnection between multiple layers in the building and interconnection between the building in the park network.
As the edge of the metropolitan area network connected to the client, you can use Gigabit Ethernet or 10 Gigabit Ethernet. Choosing Gigabit Ethernet is also 10 Gigabit Ethernet, depending on the number of customers that are gathered in 10 Gigabit Ethernet switches. If you use 10GBE switches and Layer 2 (802.1Q / P, 802.1W, etc. IEEE standard), you can quickly deploy local Ethernet services any corner of the city.
The connection between the metropolitan network can use 10 Gigabit Ethernet WAN Physical Media Layer (WAN PMD), which is compatible with the SONET's OC-192C. Such solutions allow service providers to protect and utilize existing SONET infrastructure without having to use expensive OC-192C. This approach provides an alternative to traditional OC-192C SONET interfaces to improve performance ratio.
Since SFlow (RFC3176) is embedded in the ASIC Ethernet switch, the network administrator may understand the traffic in the network, regardless of 10Mbps, or up to 10Gbps or higher regardless of the network speed.
Now, 10 Gigabit Ethernet is the main part of operators and corporate network infrastructure, selecting the right company to carry out correct investment, will ensure a higher return on investment.
Business intelligence and management advantages
With 10 Gigabit Ethernet, network managers can use real-time mode, and can also easily see network traffic of the second layer to the 7th floor with historical accumulation. Allow "forever online" to monitor, can identify interference or intrusion monitoring, discover network performance bottlenecks, get billing information or call data records, and get business intelligence from the network.
Although 10 Gigabit Ethernet technology is different from the previous Ethernet, it still belongs to the Category of Ethernet. Since very many users have already used Ethernet, 10 Gigabit Ethernet can be used to maintain the same management tools and architectures. To reduce the training time, let new services quickly expand. It will be appreciated that all levels of the network use the same system, and the management system can naturally be simplified.
