RTP packet loss healing on a bare-metal switch

Abstract

Bare-metal switches (BMS) are switches sold without an operating system (OS), i.e. including only the switch hardware. For network operators this may not only provide a cost advantage, it also allows them to customize the OS behavior to their own needs. The aim of this demonstration is to show the applicability of BMS in a carrier-grade environment. To this end, a representative use case has been implemented on a BMS, which includes the healing of RTP packet loss by automatically selecting a stream with the least packet loss from redundant uplinks. This use case demonstrates the flexibility of BMS to be adaptable to even such specific needs in a network.
