ECS Feature Changes as of May 31, 2013

This section provides information on ECS feature changes in release 14.0.

IMPORTANT:

For more information regarding features in this section, refer to the ECS Administration Guide for this release.

New ECS Features

This section identifies new ECS features available in release 14.0.

None for this release.

Modified ECS Features

This section identifies ECS features modified in release 14.0.

Support for HTTP Cookie Header in Rule Matching

This release introduces the functionality for ECS to match strings based on the configured rule in the cookie header field of a HTTP packet. The HTTP parser can parse up to a maximum of 4096 bytes in the cookie header and use the operators ‘contains’, ‘starts-with’, ‘ends-with’, and their derivaties for pattern matching.

Previous Behavior: ECS did not have the functionality to parse HTTP cookie headers to match rules on cookie contents.

New Behavior: With this release the HTTP parser can parse HTTP cookie headers and match rules based on the cookie contents.

Optimization of IP Subnet, IP Host-Pool and Port-Map-based Rulelines

ECS uses multiple optimizers to optimize rule lines for fast lookup during rule matching. With this release, the following rule lines are optimized for a better rule matching performance:

- IPv4 address-based rule-lines with a 32 or non 32 subnet mask.
- IPv6 address based rule-lines with a 128 or non 128 subnet mask.

Rulebase Change Results in Dedicated Bearer Cleanup – Behavior Change

Previous Behavior: In earlier releases, after a call comes up successfully with the configured rulebase with both default and dedicated bearers, if the rulebase is changed via CoA, the dedicated bearer remains up with no rules installed on it as the existing rules are cleared. The same bearer can get updated with rules when previously installed rules or new rules eligible to get bound are installed from the Gx interface.

New Behavior: Now, if the rulebase is changed via CoA, the new rulebase gets applied to the default bearer but the dedicated bearer gets cleared as the rules are removed, and is created if any rules are installed from the Gx interface.

For more information regarding features in this section, refer to the ECS Administration Guide for this release.

New ECS Features

This section identifies new ECS features available in release 14.0.

Regular Expression Support for Ruledef Matching

In StarOS 14.0 releases, ECS supports the use of regular expressions in the following string-based rules:

- http host
- http uri
- http url
- rtsp uri
- wsp url
- www url

For more information on regular expression support for ruledef matching, refer to the Enhanced Charging Service Administration Guide, and the ACS Ruledef Configuration Mode Commands chapter in the Command Line Interface Reference.

Service-Group QOS Support

The Service-Group QoS feature enables the ASR chassis to enforce Fair-Usage-Policy (FUP) per subscriber. This enables changing some charging-action parameters and all QoS-group-of-ruledefs parameters over the Gx interface per individual subscriber session.

For more information on regular expression support for ruledef matching, refer to the Enhanced Charging Service Administration Guide.

Modified ECS Features

This section identifies ECS features modified in release 14.0 and contains two types of modifications: enhancements and behavior changes. Feature enhancements are modifications based on customer change requests. Feature behavior changes are modifications based on software error corrections (bug fixes) that result in a change in the behavior of the feature.

Header Enrichment Encryption Licensing – Behavior Change

Previous Behavior: The Header Enrichment and Encryption feature (RSA and RC4MD5) was not protected by the relevant license. It was available via ASR5K-00-CS01HDRE but should have been protected by either ASR5K-00-CS01H-K9 or ASR5K-00-CS01E-K9.

New Behavior: The Header Enrichment and Encryption feature will now be available only with the correct licenses. The xheader-encryption CLI command in the ACS Rulebase Configuration Mode and the encryption rc4md5 CLI command in the ACS Charging Action Configuration Mode are now protected.

Header Insertion Feature Limitations – Behavior Change

In the 14.0 release, the following limitations no longer apply to the Header Insertion feature:

- Header insertion does not occur for retransmitted packets.
- Header insertion occurs for both HTTP GET and POST requests. However, for POST requests, the resulting packet size will likely be larger than for GET requests due to the message body contained in the request. If the previous limitation applies, then POST request will suffer a bigger limit due to this.
- The packet size is assumed to be less than “Internal MED MTU size, the size of header fields inserted”. If the total length of packet exceeds the internal MTU size, header insertion will not occur after the addition of fields.

The following limitation has changed:

- Header insertion for TCP OOO and IP fragmented packets:
  - TCP OOO Packets: Header insertion will occur on OOO request packets only if in the rulebase the tcp packets-out-of-order transmit after-reordering CLI command is configured, and reordering packet is received before OOO timeout.
  - IP Fragmented Packets: In case of IP fragmented packets, header insertion will occur only when all fragments are received before reassembly timeout.

For more information on X-Header Insertion and Encryption features, collectively known as Header Enrichment, and prevailing limitations refer to the Enhanced Charging Services Administration Guide.

LF as Valid Terminator for HTTP Header Fields – Behavior Change

In accordance with RFC 1945, Hypertext Transfer Protocol — HTTP/1.0, which defines CRLF as the end-of-line marker for all protocol elements except the Entity-Body, the ECS HTTP analyzer supported CRLF as terminator for HTTP header fields. However, the RFC describing “Tolerant Applications” recommends that applications be tolerant of deviations, and treat LF as a valid line terminator. The ECS HTTP analyzer now supports LF also as a valid terminator for HTTP header fields.

Previous Behavior: In earlier releases, the ECS HTTP analyzer supported only CRLF as valid terminator for HTTP header fields.

New Behavior: The ECS HTTP analyzer now supports both CRLF and LF as valid terminators for HTTP header fields.

Session Teardown Packet Rule Matching – Behavior Change

Previous Behavior: In earlier releases, zero-length TCP connection teardown packets were matching with the application-level charging rule.

New Behavior: Zero-length TCP connection teardown packets will not match to “<application> any-match = TRUE” (for example, HTTP application) or control-level charging rules.

Deployments using such application-level rules will observe the new behavior. Session teardown packets will be charged as per the action specified in “<application> any-match = TRUE (for example, http any-match = TRUE) OR “control-level rules” (for example, tcp any-match = TRUE) whichever is present in the configuration.
