page 1 Cisco Validated Design Introduction Introduction Optimizing the caregiver experience for healthcare organizations who are adopting clinical communication system is a complex task. Together, Apple, Cisco, and PatientSafe Solutions have proven the benefits of a new technol- ogy called Fastlane. When a Cisco Fast lane enabled wireless network detects an Apple iOS 10+ device running a Fast lane enabled application like the PatientTouch application from PatientSafe, wonderful things happen, and clinical teams notice. For the first time, a truly end-to-end quality of service (QoS) policy can be implemented across the switched net- work, inclusive of the Apple iOS operating system, PatientTouch, and the wireless network. With this new capa- bility, applications that your healthcare delivery organization identifies as business critical can specify what level of service the applications should receive. Apple, Cisco, and PatientSafe recently conducted onsite Fast lane QoS validation, demonstrating the considerable advantages for the clinical mobility user: • Improved audio and video quality. • Optimized clinical application performance. • Reduced battery consumption. This guide serves a number of purposes related to Fast lane and PatientSafe Solutions. First, it describes the advantages demonstrated during the joint Apple, Cisco, and PatientSafe Solutions testing and translates how those advantages result in a significantly improved end-user experience and clinical benefits. Second, it provides technical details regarding the results. Lastly, it provides implementation details so that your healthcare delivery organization can improve their clinical communication end user experience. FasT lane OvervIew Prioritizing business-critical applications such as clinical communications systems can be controlled through the use of a whitelist policy that is pushed down to the Apple iPhone or iPad through the use of a Mobility Device Manager (MDM). Applications that are Fast lane enabled and are explicitly named in the whitelist receive priority treatment in a truly end-to-end fashion. This prioritization is unique to Cisco and Apple and extends the priority and optimization within the Apple iOS and across the Cisco wireless and switched network. When Apple introduced iOS 10, it enabled a series of QoS based queues that application developers can use to prioritize traffic as it passes down the stack and eventually reaches the wireless network adapter. These nine queues take into account the data types and priorities necessary to enable an optimized end-user experi- ence. Voice traffic, for example, is typically composed of many relatively small packets that require extremely low latency. High-priority service of data that has been placed into the voice priority queue is critical to reducing latency and in passing them to the network PHY layer. To achieve this granularity, iOS 10 introduced a highly optimized QoS architecture that can optimize the end-user experience for Fast lane-enabled applications. Prior to this, tagged application traffic was mostly serviced with equal priority. This means large file transfers received the same priority as voice traffic. In a mobile device with constrained resources such as packet buffers or the congested wireless network to which it is attached, preser- vation of priority queuing is top-of-mind and addressed by Fastlane.
