Revision as of 13:26, 3 October 2019

Background

Whilst Songcasting in large-scale mode, Linn DS players generate significant amounts of Multicast traffic on the network. Many consumer grade network switches, including many all-in-one router/switch/WAP units will broadcast this Multicast traffic to ALL devices on the network, rather than just those which have requested it.

Problem

This Multicast traffic may cause the WAP to be overloaded

  • wireless network malfunctions and becomes unreliable
  • unable to connect to the wireless network.

Solution

  • All DS players which are participating large-scale Songcast must use wired network paths between themselves.
  • The network traffic must be filtered to ensure that Multicast traffic is not sent over the wireless network.

IGMP Snooping

This is a feature of network equipment, and may require an upgrade to the network infrastructure to operate successfully and prevent wireless network issues

WAP (or all-in-one box)

  • Enable IGMP snooping in the options

Managed Switch

  • Enable IGMP snooping in the options
  • Ensure network path between DS players and WAP go through the switch
