Required ResourcesThese are the resources and equipment required to complete this activity:• Case study guidelines, presented in the Course Introduction• CP Hotels Case Study Scenario• A workgroup consisting of two to four students• Blank sheets of paper and a pencilCP Hotels Case Study ScenarioNetwork TopologyThere are four large headquarters (HQ) buildings, two data centers (A and B), eight callcenters, and 2000 hotel sites in the CP Hotels network. There are also connections to partners(suppliers and local packages such as sports and tour vendors, etc.).The two data centers are identical to each other. The network is structured around two coreCisco Catalyst 6509 Series Layer 3 switches in each of the data centers. They areinterconnected through dense wavelength-division multiplexing (DWDM) over a fiber ring.Various network modules connect to the core two switches in each data center. Each moduleterminates in two core-facing routers or Layer 3 switches. Each core-facing router or Layer 3switch in the module connects to both core Cisco Catalyst 6509 Series switches in its datacenter building.The data center modules are:• Server Farm (Server) Module• Hotels Module• Call Center Module• Partner Module• Corporate Internet Access Module• HQ Router ModuleRemote sites or partners connect to the relevant module in each data center. Dual local links areused where feasible to provide increased availability. In such cases, one link goes to each datacenter.10 Designing Cisco Network Service Architectures (ARCH) v2.0 © 2007 Cisco Systems, Inc.
