宽带 Cable Modem 网络还处于初期阶段,它受困于一个关键的问题:缺少公认的工业标准。据统计,现在至少有三个线缆标准体系,每个标准和其它标准之间由于些微差异而导致结果的分歧。IETF(Internet Engineering TaskForce)也正在开发基于线缆的 IP 标准。但该协议只是一个软件协议,对硬件开发没有影响。最终标准的真空驱使生产厂商开发它们自己的专有技术,但如今它们不得不开始放弃这些技术。
The Broadband Cable Modem network is still in its infancy, and it suffers from a key issue: the lack of accepted industry standards. According to statistics, there are at least three cable standard systems now, and the differences between the results of each standard and other standards due to slight differences. IETF (Internet Engineering Task Force) is also developing a cable-based IP standard. But the agreement is only a software agreement, has no effect on hardware development. The ultimate standard vacuum drives manufacturers to develop their own know-how, but now they have to start abandoning those technologies.
