将多个交换端口集成为交换机的主干技术尽管不是一种新技术,但直到最近厂商才开始制定这个技术的通用标准。有了这个标准,集成的交换端口将可以提供千兆位以太网的接入速率,这将在更大程度上保护企业在基础设施上的已有投资。今年夏季,IETF(Internet工程任务工作组)讨论并制定了端口集成技术标准的草案,允许不同厂商的交换机产品的互连。由于标准是新拟定的,还没有来得及命名。涉及的问题乍看上去好象很简单,但由于它的实现涉及到修改分段网络的基本规则,事实上交换主干技 Backbone technology that integrates multiple switch ports into a switch Although not a new technology, it was not until recently that vendors started to develop a common standard for this technology. With this standard, integrated switch ports will provide Gigabit Ethernet access rates, which will to a greater degree protect the enterprise’s existing infrastructure investments. This summer IETF (Internet Engineering Task Force) discussed and developed a draft of the standard for port integration technology that allows the interconnection of switch products from different vendors. As the standard is newly proposed, it has not had time to name it. The issues involved seem at first glance to be very simple, but since its implementation involves the basic rules for modifying a staging network, in fact switching backbone technologies
