Competition & Positioning
O que é um SBC?
• Um Session Border Controller (SBC) é um
dispositivo de reconhecimento de sessão VoIP
que controla a admissão de chamada para uma
rede em sua “borda” e, opcionalmente
(dependendo do dispositivo), executa uma série
de funções de controle de chamadas para aliviar
a carga sobre os elementos de chamada dentro
da rede.
O que é um SBC? (cont.)
• O Session Border Controller divide-se em duas
partes logicamente distintas.
• A função Signaling SBC (SBC-SIG) controla o
acesso de mensagens de sinalização VoIP para o
núcleo da rede, e manipula o conteúdo dessas
mensagens.
• A função Media SBC (SBC-MEDIA) controla o
acesso de pacotes de mídia para a rede, oferece
serviços diferenciados e de QoS para diferentes
fluxos de mídia.

Competition & Positioning
Onde são usados os SBCs?
• Session Border Controllers normalmente são
implementados na DMZ de uma rede.
• Session Border Controllers podem ser
implementados em quaisquer dos seguintes
cenários.
Cenários possíveis
• Na borda entre um SP e seu cliente (User Network Interface –
UNI)
• Na borda entre dois SPs com acordo recíproco a respeito do
tráfego VoIP (Network-to-Network Interface – NNI)
• Dentro da estrutura do SP ofertando serviços VPN para seus
clientes, fazendo o bridge de chamadas através das
localidades VPN de seus clientes
• No core de uma rede, com o intuito de resolver problemas de
topologia para comunicações internas
• Fazendo a função de “transcoding” centralizado
Cenário UNI
Cenário NNI

End of Sale – Avaya Aura SBC
• Effective May 6th 2013, Avaya will no longer sell
(make commercially available) the Avaya Aura
Session Border Controller (AA-SBC).
• The HP DL360 server which serves the AA-SBC
software will be used for the A SBCE code so no
hardware swap is required. If the customer has new
requirements for more than 750 SIP Trunk Sessions,
a new A SBCE will be required with new hardware.
