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.
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.

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:
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.
