• 5 Tendências globais em Telecom
– #1: Mobilidade, conectividade em qualquer lugar a
qualquer tempo, em qualquer dispositivo
– #2: Crescimento exponencial de tráfego, aceleração de
video e aumento de usuários desafiam as arquiteturas
atuais das operadoras
– #3: Crescimento de serviços na nuvem
– #4: Mobilidade de usuários levam ao uso de rede única
para serviços fixo/móvel
– #5: Mudanças no modelo de negócios levam a
considerar novas arquiteturas

• Many live deployments
• Users / content / Networks moving to
IPv6 (with or without IPv4)
• IPv6 adoption strategies
Network first, service later (IPv6 only,
dual-stack)
Service first, network later (6rd,
IPv6overIPv4)
• Still some development items
LDP over IPv6
Appliances: voice, Firewall, Security,
