北电网络公司的Shasta用户服务系统(SSS:Subscriber Service System)是一种面向运营商的宽带智能IP业务网关,它在逻辑上可把数万名用户汇聚在一起,并且集中为这些用户提供客户化的IP服务,包括虚拟专用网(VPN)、可管理的防火墙、服务质量策略、及强制网络门户等。 SSS能与北电网络的其它产品系列无缝地实现互通,其目标集中在新建的IP公共数据网络的“用户边域”。“用户边域”是网络操作员能够向用户提供可增值服务的唯一区域,这一点与目前电话公司在交换中心设置Centrex业务相似。SSS是具有等同于电话公司第5类交换机的一种真正的IP设备,它在IP用户汇聚和管理、业务设置及数据包处理方面具有很高的可扩展性。对于IP服务供应商而言,Shasta解决方案能帮助他
Nortel Networks’ Shasta Subscriber Service System (SSS: Subscriber Service System) is a broadband intelligent IP services gateway for operators that logically brings together tens of thousands of users and centrally provides them to customers IP services, including virtual private networks (VPNs), manageable firewalls, quality of service policies, and captive web portals. SSS seamlessly interoperates with Nortel Networks’ other product lines with the goal of focusing on the “user edge” of the new IP public data network. User Edge is the only area in which network operators can offer value-added services to subscribers, as is the case with current telephone companies setting up Centrex services in switching centers. SSS is a true IP device with a Class 5 switch equivalent to a telephone company with high scalability for IP user aggregation and management, business setup and packet processing.
