Although ATM's related technologies and research have developed very fast, ATM is generally to be further improved.
Regardless of its problems in the practice of its development and use, such as the traffic management of ATM and
The technique of congestion control is not ideal; the price of ATM products is generally high; the standard of ATM
Impermatics, there are some problems in terms of adaptability, versatility and interoperability.
Despite this, AM is a new exchange technology and the mainstream of communication technology in the next century.
undoubtly. ATM is earliered as a new generation of telecommunications technology foundation. The advantage first
Reflected on the construction of the backbone, because on the one hand it has the capacity of GB / S, then, due to VP, VC
The flexibility of technology adoption, capacity, and processing is that the current time-off call exchange network cannot match.
From this point of view, it also determines its position in the future. On the other hand,
Formerly popular local area networks, although there are also some high-speed network technology, such as FDDI, 100Base-T
Wait, but there is a common feature of the network that uses these technologies, that is, based on the so-called media.
enjoy. In this way, excessive sharing will inevitably reduce the actual transmission rate, which has become such a high-speed network.
One of the crux. Effective way to solve this problem is to convert from "shared" to "exchange",
And ATM's new exchange technology has its own unlimited advantages. 2MB / s, 34MB / s, 45MB / s
And 155MB / s ATM products have been accepted by people. In the spring of 1995, the ATM Forum pairs about LAN
Simulation, the new ATM adaptation layer and low speed access (E1 / T1) are standardized, which makes corresponding
The competitiveness of ATM products is further strengthened. In the production of ATM products, there have been more than 50 manufacturers.
Production ATM products, there are more than 100 manufacturers in the development of ATM exchange, line and routing equipment.
From the commercialization of ATM, there are more than ten ATM live trials only in the United States.
Among them, the information on the North Carolina is the largest ATM network in the United States. In Canada, now
Seven local ATMs have been put into use; in Europe, Finland, France and Germany have also opened some
ATM commercial business; in the Asia Pacific region, such as Japan, DPRK, Singapore, etc. also have similar plans. Exhaust
The final improvement of the ATM technology and the maturity of the corresponding market will wait for the next century, but ATM technology is determined.
A new technology is limited to the laboratory, currently, it has begun to travel from the laboratory to practical and commercial
Using, with the improvement and development of its related technologies, it will be widely used. There is no doubt, ATM
Combining with the synchronous fiber optic network (SONFT) will constitute the main body of the 2L century communication.
