Subscriber-Aware Ethernet with Cisco ISG Support on Cisco 7600 Series ES+ Line Cards
Cisco Intelligent Services Gateway (ISG) is the premier policy management solution from Cisco, providing dynamic control of subscriber services and industry-leading subscriber control for PPP and native IP sessions. With this functionality, PPP or native IP subscribers obtain full lifecycle management, AAA support, and support for dynamic policy enforcement.
Release 12.2(33)SRE, extends the functionality that is currently available on the SIP-400 to the ES+ line cards.
Benefits
Cisco 7600 Series subscriber-aware Ethernet is an important strategy for service providers implementing triple-play that want to:
• Simplify client protocols for video and voice with DHCP-initiated IP session while maintaining HSI services with PPPoE
• Eliminate redundant investment in legacy BRAS by utilizing zero-touch subscriber management functions in the aggregation network
• Scale subscriber bandwidth while maintaining per-subscriber control
Service providers can now distribute provisioning and per-subscriber control into their Ethernet access infrastructures. Cisco 7600 Series features include:
• IP sessions with Transparent Auto-Logon support
• PPPoE sessions
• Cisco Intelligent Services Gateway (ISG) with dynamic MQC policy assignment
• ISG to Service Control Engine (SCE) control bus
• High availability with PPP and IP session SSO/EFSU
