Juniper 高性能交换产品介绍 陈剑 2010.3.2 EX4500高密度万兆汇聚交换机 推荐Juniper EX的X大理由 EX Architecture Leverages JUNOS Infrastructure: 模块化架构 控制平面和转发平面完全分离 线速转发 JUNOS CLI: hierarchical, 2-phase commit Leverages ScreenOS Security 久经考验的安全 统一接入控制 标准的802.1X支持，同时扩展功能： 可以基于交换机静态MAC地址表进行认证。 基于Radius，实现动态VLAN功能。 支持Guest VLAN 支持Voice VLAN 基于Radius VSA属性， 实现三层防火墙/IDS动态联动 支持IP telephones的802.1X认证。 竞争分析 Juniper EX vs. Cisco Catalyst EX2200 主要竞争型号：C2960G和C3560/G EX3200 主竞争型号：C3560E和3560G EX4200、EX4500 主竞争型号：C3750E和3750G和C4948、C4900M、C4500系统 EX8200 竞争型号：Nexus7000、Catalyst6500， EX2200 vs C2960 EX3200 vs C3560G/E EX4200 vs C3750G/E EX4200 vs C4948 EX4500 vs C4900M EX4200 vs C4500E EX8208与Cisco上一代交换机产品比较 Juniper EX8208作为全新一代的核心交换机产品，产品无论从单板性能，还是整机性能来看，与Cisco上一代的旗舰产品相比有非常明显的优势。 Juniper EX8208与Cisco Nexus 7010比较 Juniper EX8216与Cisco Nexus 7018比较 Juniper与Cisco数据中心解决方案比较 * * * The Stratus Project, which has already filed over 30 patent applications, is a multi-year initiative within Juniper to get to the end-stage of a single fabric across the entire data center. Today, Juniper is delivering a number of technologies in the first phase of the simplification of the data center network: Starting with the access layer – Virtual Chassis technology enables up to 10 devices to be managed, operated, and maintained as if they are one. So a single control plane function across 10 devices effectively reduces the number of managed network devices by up to a factor of 10. If you are managing 500 switches in your data center today, imagine how much simpler things would be if you only managed 50! A single config file, a single management IP address, and a single OS image across 10 devices. Typically, you would run two uplink per rack, well with VC technology, uplinks are shared across the entire VC. This cuts down the number of very expensive aggregation ports that eat up a lot of budget. In the Core layer – you will notice that we do not need an aggregation layer. By decreasing the number of upli
