La sorgente deve essere multicast, da me dice che fa join del gruppo ma poi dice di usare l’unicast, infatti non vedo passare pacchetti udp (che sono tipici del multicast)

Comunque non so se è normale ma verso la fine della partita nel log vedo continui infiniti join e leave dello stesso gruppo, ora che ho chiuso lo stream si è fermato.

la join e leave la fa...in teoria il leave non dovrebbe farlo

ecco un esempio

la app DAZN fa la richiesta al nanoCDN agent del flusso

Questi sono log del tim hub o del tim box?

MATROG · 25 Settembre 2021

timbox

Per il derby della capitale il multicast è attivo?

Si

qwerty159 · 2 Ottobre 2021

Guardo Canale5 tramite la piattaforma timvision, traffico multicast attivo mentre se vado a vedere il derby della mole il traffico va solo in unicast, come è possibile?

MATROG · 2 Ottobre 2021

Molto strano, i gruppi multicast erano attivi, se provi con la partita dell’inter?

ERCOLINO · 3 Ottobre 2021

Per i TIM HUB sembra che sia partito in automatico (senza dover far richiesta al 187) il downgrade massivo alla 2.2.1 visto che le successive versioni 2.3.1 e 2.3.2 avevano un sacco di problemi

Forse la stessa cosa anche per gli Smart Modem Plus

Ovviamente si perde il Multicast

L'avevo notato oggi che era tornato alla 2.2.1...

Infatti ora, invece di "pacchetti Multicast", trovo la voce "pacchetti protocollo sconosciuto" che non c'era prima...

Idem con "patate".

MATROG · 5 Ottobre 2021

servono i log del timbox per capire

MATROG · 16 Ottobre 2021

per Spezia - Salernitana, niente multicast da me

Codice:

10-16 15:06:06.449  9141  9168 W NanoCdnLib-core: ctrlchannel:No frame received into 239.200.0.0:5004 during 60 seconds, perform a leave and join

cruelxx · 16 Ottobre 2021

Spezia salernitana, fluido niente scatti e buona qualità.

francy83 · 20 Ottobre 2021

Ho messo come modem il tim hub technicolor aghp con firmware 2.3.1. Ma i pacchetti multicast, anche sul canale 1005 sono a zero ( Pacchetti persi
0 Pkd 0 Pkd
Pacchetti Broadcast
0 Pkd 0 Pkd
Pacchetti Multicast
0 Pkd 0 Pkd
Pacchetti Unicast
116704 Pkd 189443 Pkd
Pacchetti
116704 Pkd 189443 Pkd
Errori
0 Pkd 0 Pkd
Bytes
14088828 Bytes 239565622 Bytes ), su timbox con android 8

come mai secondo voi?

anche se con wireshark vedo pacchetti di questo tipo: 36 16.014232 192.168.1.120 224.0.0.7 UDP 242 8001 → 8001 Len=200, che dovrebbero essere multicast o sbaglio?

MATROG · 20 Ottobre 2021

Secondo me non stanno mandando più pacchetti multicast, nemmeno per Canale5.

In ogni caso il gruppo multicast è 239.200.0.0

MATROG · 31 Ottobre 2021

sulla mia linea non si vedono più pacchetti multicast

alice_anto · 31 Ottobre 2021

doveva essere il fiore all'occhiello di tim questo multicast invece mi sa di flop clamoroso

Ho pure speso 200 Euro per il router per poter sfruttare questo Multicast che si è rivelato una bufala clamorosa. Anche qui sul forum si è data troppa enfasi...

Ma quindi il multicast è definitivamente morto?
