A global retail chain deploys the Cisco 2851-WAE/K9-2851 router with NME-WAE-502-K9 and WAAS Trans ASK9 128F/512D modules at ten remote stores to optimize SAP ERP access over a congested MPLS link. By caching database queries, compressing traffic, and reducing TCP round trips, stores experience sub-second page loads and 60% bandwidth savings. The outcome is real-time inventory updates, faster order processing, and a 45% reduction in support tickets for ERP timeouts.
A regional bank uses Cisco 2851-WAE/K9 and NME-WAE-502-K9 equipped with WAAS Trans ASK9 128F/512D cards to accelerate nightly VM replication between its primary data center and a geographically diverse DR site over a 50 Mbps WAN. Deduplication and byte-level delta transfers cut replication windows from 8 hours to 2 hours, enabling continuous data protection and meeting a 4-hour RTO. The bank achieves regulatory compliance, minimizes data loss risk, and ensures instant failover readiness.
An engineering firm with 200 CAD designers implements Cisco 2851-WAE/K9-2851 with NME-WAE-502-K9 and WAAS Trans ASK9 128F/512D at its headquarters to accelerate virtual desktop infrastructure (VDI) sessions hosted in a public cloud. Traffic optimization, protocol spoofing, and multimedia caching deliver a 70% reduction in latency and up to 4× faster file transfers when working on large 3D models. Engineers experience fluid desktop interactions, shortening design cycles by 25% and boosting project throughput.
