Just to explain BBC setup and the ping result is not meaningful BBC makes TV & Radio content and puts on their servers. BBC have outsourced delivery of this content to CDNs (Content Deliveery Networks) - Akamai and Limelight. These companies have their own networks and servers and provide "protection" against malicious attacks (e.g. DDoS). They are used by other broadcaster (e.g. ITV also uses Akamai) and content providers. When a user requests a program from BBC - it gets redirected to either Akamai or Limelight who in turn rout to their regional centre whic in turn load shares onto a server. Frequenty access content is often cached on a CDN server. Rarely accessed content will be fetched from BBC servers. Live station provide a level of difficulty (I.e. servers cannot have much program content cached as it is generated in realtime) and usually have special measures to ensure stream is always in near realtime (e.g. if network has loads, packets are delayed - overtime the radio station will get further and further behind realtime - e.g. big ben chimes at 5 past the hour is not acceptable) . As an example why pinging BBC URL as a test for latency - the following is an URL for R4 live - which delivered by Akamai and also from a pool of servers. https://as-dash-ww-live.akamaized.net/pool_904/live/ww/bbc_radio_fourfm/bbc_radio_fourfm.isml/dash/bbc_radio_fourfm-audio=96000-243659695.m4s ------------------------------------------------------------------------ bpa's Profile: http://forums.slimdevices.com/member.php?userid=1806 View this thread: http://forums.slimdevices.com/showthread.php?t=109826 _______________________________________________ plugins mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/plugins
