RADIUS Accounting extensions for IPv6 draft-maglione-radext-ipv6-acct-extensions-01 R. Maglione – Telecom Italia B. Varga - Magyar Telekom S. Krishnan, A. Kavanagh – Ericsson J. Kaippallimalil – Huawei
Background • RFC 2866 and RFC 2869 specify RADIUS attributes to carry statistics about packets/octets/Gigawords sent/received over a port • This document introduces new RADIUS attributes to carry IPv6 volume counters in RADIUS Accounting messages
Deployment Scenario • Broadband environments: dual-stack IPv4/IPv6 scenario AAA Radius Server Residential Gateway BRAS Access Node Single PPP Session for both IPv4 and IPv6
Why new attributes? • There is a suggestion on list to re-use existing attributes by duplicating the accounting stream for each single session: • one stream for IPv4 another for IPv6 traffic • Acct-Multi-Session-Id used to link the two streams together • This approach seems operational too heavy for both the BRAS and the RADIUS system • Defining new attributes appears a simpler solution
RADIUS Accounting Attributes Initial proposal Suggestion from the list
Next Step • Adopt as a WG item?
