对于大型企业来说,在各个分支机构之间建立专有网络无疑是相互之间进行沟通的最佳方式,但此种办式需要的投入价值不菲。因而各个厂商纷纷推出自己的VPN解决方案。Ascend公司的MultiVPN体系结构支持三种VPN技术:虚拟专有远程网络(VPRN)、虚拟专有中继(VPT)和虚拟IP路(VIPR)技术,允许用户使IP、帧中继和ATM服务构建VPN。MultiVPN解决方案通过在基础设施中采用VPRN、VPT或VIPR技术,使得企业用户可以获得与现有应用的兼容性。
For large enterprises, establishing a private network among the various branches is undoubtedly the best way to communicate with each other, but the investment required for such an approach is of great value. Thus all manufacturers have introduced their own VPN solutions. Ascend’s MultiVPN architecture supports three VPN technologies: Virtual Private Remote (VPRN), Virtual Private Trunk (VPT), and Virtual IP Routing (VIPR) technologies that allow users to enable IP, Frame Relay, and ATM service building VPN. MultiVPN solutions enable business users to gain compatibility with existing applications by adopting VPRN, VPT or VIPR technologies in their infrastructure.
