EX 系列以太网交换机产品组合

 

概览

高效的企业深知高性能网络的重要性。瞻博网络的 EX 系列以太网交换机推出了这样的一套解决方案：为维护高成本、复杂的传统交换机网络提供创新的替代方案。

经针对高效企业的专门设计，EX 系列以太网交换机允许公司按自己的步伐扩容他们的网络，缩减高额的前期投资。EX 系列交换机提供当今企业所需的电信级可靠性、安全风险管理、虚拟化和应用程序控制，降低拥有总成本 (TCO)，同时还允许他们在未来的几年里以经济节约的方式进行升级。

 

特性和优点

瞻博网络的 EX 3200、EX 4200 和 EX 8200 系列以太网交换机提升联网的经济性，以其在五个关键领域的整体创新，提供了真正高性能的解决方案。

• 电信级可靠性：瞻博网络的 EX 系列以太网交换机采用同样经现场验证的瞻博技术——包括高性能 ASIC、电信级系统体系结构和 JUNOS™ 软件——这是世界上最大的服务提供商网络也采用的。从而打造出强劲、成熟和高可靠性的网络基础设施。
• 安全风险管理：瞻博 EX 系列以太网交换机紧密地与瞻博统一接入控制 (Unified Access Control, UAC) 解决方案集成在一起，以提供基于用户身份、设备和位置的细粒度访问控制和使用策略。
• 虚拟化：EX 4200 系列交换机采用瞻博 Virtual Chassis™（集群交换）技术，可实现最多 10 台 EX 4200 交换机的互连，且运行起来就像单一的逻辑系统一样。通过采用集群交换技术，用户可以高的性价比、微型的形状参数获得传统机箱系统所具备的可靠性、性能、管理性和高端口密度
• 应用程序控制：为确保应用程序传输流量获得恰当的优先级，整个 EX 系列以太网交换机每个端口可支持八个服务质量 (QoS) 队列——足以为控制平面、语音、视频和多层数据流量建立独立的队列，另外还有空间融合其他网络，如建筑物自动化和安全摄像头。
• 较低的拥有总成本 (TCO)：这一高性能、高密度 EX 系列允许用户走从小到大的递增式发展之路。JUNOS 软件通用版本在瞻博路由器和交换机上的广泛采用确保了贯穿基础设施的一致性，并可加速学习曲线。统一化管理工具巩固了系统监控和维护，节省时间和金钱。
