    • A distributed data center topology having at least a pair of active data centers that can recover from a disaster at one of the data centers and achieves load balancing using IGP (Interior Gateway Protocol) between data centers. The distributed data centers use virtual IP addresses, route health injection and Border Gateway Protocol (BGP) for business continuance, disaster recovery and load balancing. Active applications are deployed at each data center to provide a logical active/standby configuration for certain applications. Alternatively, active applications are deployed at both sites and BGP routes traffic to the closest data center edge router. Load balancing occurs over an internal IGP link between sites.
    • 分布式数据中心拓扑具有至少一对活动数据中心,可以在数据中心之一从灾难中恢复,并使用数据中心之间的IGP(内部网关协议)实现负载平衡。 分布式数据中心使用虚拟IP地址,路由健康注入和边界网关协议(BGP)进行业务连续性,灾难恢复和负载平衡。 活动应用程序部署在每个数据中心,为某些应用程序提供逻辑主动/备用配置。 或者,活动应用程序部署在两个站点,BGP路由流量到最接近的数据中心边缘路由器。 通过站点之间的内部IGP链路进行负载平衡。

    • A reliable and secure data-center. The data center includes a first data-center tier that is adapted to connect to an external network and an internal portion of the data center. A first firewall instance interfaces the first tier and the external network. A second firewall instance interfaces the first tier and the internal portion of the data center. In a more specific embodiment, the first firewall instance and the second firewall instance accommodate Internet Protocol SECurity (IPSEC) terminations using one or more VPNSMs. In this embodiment, the first data-center tier implements a core tier that includes one or more core switches that facilitate implementing the first firewall instance and the second firewall instance. The interior portion of the network represents a DeMilitarized Zone (DMZ) that includes a second tier that is connected between the first data-center tier and a third tier. The second tier implements an aggregation tier that includes one or more aggregation switches that facilitate implementing reverse-proxy caching. Overall Layer-3 design methodology is used within each tier and across tiers for optimized packet switching. The aggregation tier includes one or more aggregation-tier service modules for implementing load balancing, Secure Socket Layer (SSL) offloading, and/or the reverse-proxy caching.
    • 一个可靠和安全的数据中心。 数据中心包括适于连接到外部网络和数据中心的内部部分的第一数据中心层。 第一个防火墙实例接口第一层和外部网络。 第二个防火墙实例接口数据中心的第一层和内部部分。 在更具体的实施例中,第一防火墙实例和第二防火墙实例使用一个或多个VPNSM来适应因特网协议安全(IPSEC)终端。 在该实施例中,第一数据中心层实现包括一个或多个核心交换机的核心层,该核心交换机有助于实现第一防火墙实例和第二防火墙实例。 该网络的内部部分代表一个非军事区(DMZ),其包括连接在第一数据中心层和第三层之间的第二层。 第二层实现一个聚合层,包括一个或多个聚合交换机,便于实现反向代理缓存。 在每个层级和跨层中使用总体层3设计方法来优化数据包交换。 聚合层包括用于实现负载均衡,安全套接层(SSL)卸载和/或反向代理缓存的一个或多个聚合层服务模块。
