IPv6 and ICMPv6 Support in Enhanced Charging Service
StarOS 9.0 introduces support for IPv6 and ICMPv6 packets and their parsing in the
Enhanced Charging Service.
Enhanced Charging Service.
ECS can now parse both IPv4 and IPv6 packets and pass them to upper layers for analysis.
ECS will match the rule based on IPv6 fields and generate various statistics for IPv6
packets. Dynamic routing used by various analyzers like FTP, RTSP, RTP, and SIP also
supports IPv6 addresses.

The enhancement to ECS in Release 9.0 provides appropriate CLIs to configure IPv6 fields
in rules and EDRs. Various CLIs are provided to configure rules related to IPv6 fields for
charging and routing. Several fields in EDRs give IP address. ECS will also support IPv6
addresses in these EDR fields. Show command CLIs which show IP addresses support IPv6
addresses as well. The various logs in ECS which log IP addresses along with other
information, supports IPv6 addresses as well. ECS supports various header fields of IPv6 in
EDRs. In config-acs-edr mode, ECS supports generating EDRs for IPv6 fields.

StarOS 9.0 also supports ICMPv6 packets and their parsing in ECSv2. The header structure
of ICMP and ICMPv6 is similar but the values of header fields like type and code have
different meaning in the two.

With the support for IPv6 in ECS, AAAA record type is now supported in DNS for IPv6
addresses.
addresses.
URL Filtering
This release supports the URL Filtering feature, which simplifies using rule definitions for
URL detection. Prefixed URLs are URLs of the proxies. A packet can have a URL of the
proxy and the actual URL contiguously. First a packet is searched for the presence of proxy
URL. If the proxy URL is found, it is truncated from the parsed information and only the
actual URL (that immediately follows it) is used for rule matching and EDR generation.
