Borg and Christopher Swenson, Atea Networking Specialist, designed an elegant solution using Performance
Routing (PfR) in Cisco Integrated Service Router Generation 2 (ISR G2) routers. The firm uses PfR and DMVPN,
components of the Cisco Intelligent WAN (IWAN) solution. PfR selects the best path for each application based
on criteria such as reachability, delay, loss, and jitter. It also improves application availability by dynamically
detecting and routing traffic around network problems and can optimize path selection based on link use or circuit
pricing.

Swenson says, “We applied PfR’s sophisticated triangulation and synchronization capabilities to support
simultaneous carrier connectivity. If a link becomes congested, crew members can switch to using one carrier for
upstream connectivity and another for downstream connectivity, which significantly improves reliability and
bandwidth performa

After Borg and Swenson conducted a successful three-month proof of concept, Atea began installing Cisco 1900
Series ISR G2 routers on smaller vessels and Cisco 2900 Series ISR G2s at the docks. Plans for installing the
ISR G2s in aircraft are in the works.

As shown in the figure below, each onboard Cisco ISR G2 router connects its ship or vehicle to the WAN and to a
master controller that detects and enforces enterprise-wide access and security policies. The onboard router
monitors bandwidth levels and automatically routes upstream and/or downstream traffic to the best carrier service
when performance drops below preset levels.

switching between them to provide the best communication performance.
“I feel we have truly made a difference implementing the Cisco ISR G2 PfR
solution. The ROI was fast, the solution was inexpensive, and we exceeded
the expectations of our customer.
