Traffic shaping

Info
  • The bounded latency of Milan is ensured by using traffic shaping mechanisms.
  • The Stream Reservation Protocol (SRP) makes sure that the required bandwidth is available between a Talker and a Listener.
  • The Forward Queuing for Time-Sensitive Streams (FQTSS) ensures that packets are transmitted so that they reach their destination in time.
  • Up to 75% of the available bandwidth can be used for Milan traffic. If no stream requires the bandwidth, it is available for all other traffic.

Traffic shaping is an essential part of Milan and the biggest difference compared to other networked audio protocols.

Two components are crucial for traffic shaping:

  1. The Stream Reservation Protocol (SRP) that configures a path from a Talker to a Listener.
  2. The traffic shaper in a switch. The technology is based on the credit-based shaper and is often referred to as Forwarding and Queuing for Time-Sensitive Streams (FQTSS).
