千兆位以太网QoS的实现OA
QoS implementation by Gigabit Ethernet
千兆位以太网和ATM技术是目前主干网中普遍应用的网络技术。QoS(Quality ofService,服务质量)是判断网络性能的一个基本标准。在QoS方面,ATM提供了可靠的显式QoS保证,但其成本昂贵。随着技术的发展,千兆位以太网主要从2个方面实现了QoS:IEEE802.1Q/p,RSVP等一系列标准和协议的制定;以及第3层交换技术的应用。千兆位以太网以其相对较低的成本和足够的QoS保证,成为目前最实用的企业主干网解决方案。
Gigabit Ethernet and ATM are mechanisms widely employed innetwork at preseat. According to network performance, one basic standard is QoS (Quality of Service ). ATM provides reliable and explicit QoS, but cost too much. With the development of technologies, Gigabit Ethernet has also provided QoS from two aspects: one is the emergency of a set of protocols and standards, such as IEEE 802.1Q/p, RSVP and so on; another is the implementing of Layer 3 switching t…查看全部>>
