Cisco and Apple: a collaboration steeped in technical innovation By Matt MacPherson, Cisco March 23, 2021
I’m extremely pleased
about our latest collaboration with Apple called
Fastlane+.
Fastlane+ builds on our current Fastlane QoS capability by adding
advanced scheduling intelligence to optimize the application
experience. This allows Fastlane+ to better understand application
requirements and dynamically schedule network resources to meet
them. With Fastlane+ we’re
applying the technology in the Wi-Fi 6 standard for deterministic
scheduling (OFDMA
and TWT). In
highly congested environments (60% Channel Utilization or more)
Fastlane+ enables iPhone and iPad devices to send an Advanced
Scheduling Request (ASR) trigger to Cisco Catalyst Access Points.
This notifies the network that a user is initiating a Webex,
FaceTime, or other mission-critical, latency-sensitive application. The Fastlane+ ASR
trigger consists of information such as the periodicity of the
traffic and its bit rate. Because voice and video traffic typically
have predictable bit rates, traffic patterns, bandwidth, and latency
requirements; Fastlane+ allows the network to estimate the client’s
demand and preemptively schedule airtime on the access point. This
provides mutual optimization for both the device and network and
enables the network to intelligently make decisions on how it
produces the best experience for the end user. With Fastlane+ the
goal is to make sure the network can provide the best overall
experience for iPhone and iPad users in congested environments. It
was developed with the goal to minimize delay while optimizing
throughput characteristics deterministically. In addition, we made
Fastlane+ easy; device users don’t turn it on, they’re not even be
aware of it, the magic happens behind the scenes using AI in both
the device and the network. In real-world test environments, the AI
proved itself; Fastlane+ showed a dramatic increase in MOS scores
and throughput while significantly decreasing latency and jitter.
