Nine-Tier Termination Name Hierarchy

---

This feature adds support for a nine-tier termination name schema, where the multi-tier prefix is supplied by the media gateway controller (MGC), and the final element, the channel ID, is generated by the media gateway (MG). All MGCs which the MG is configured to contact must use the same termination-name schema. Termination is the point of entry or exit of media flows relative to the MG. The MG understands how the flows entering and leaving each termination are related to each other.

This feature plays an important role in identifying the company, transaction service (such as voice or video), and termination attributes (such as access, backbone, etc.).

Restrictions for Nine-Tier Termination Name Hierarchy

•Only the final element may contain the CHOOSE ($) wildcard. The DBE will not extract any meaning from any elements of the termination ID. The exception: " * " is reserved for wildcard notation.

•Multi-tier prefixes can be less than nine tiers, but must have the same depth.

Information About Nine-Tier Termination Name Hierarchy

The MG assigns a channel ID that is unique across all terminations realized on the data border element (DBE). Using a unique channel ID ensures that the termination ID as a whole is unique across all terminations on the DBE. If a multi-tier prefix is not desired, the MGC may use a Choose wildcard for the termination ID, that is $, in which case the MG allocates a prefix in the form: ip/<flow-id>.

The only element within the hierarchy which may contain the CHOOSE ($) attribute in an ADD request from the MGC is the channel element, which is the final element. The full termination name is stored persistently.

The termination naming hierarchy is extended to include nine tiers and is defined as follows:

<operator> / <service> / <subscriber-class> / <Reserved1> / <physical-interface-id> / 
<Reserved2> / <sub-interface-id> / <termination-attribute> / <channel>

<operator> : "yourcompanyname", "east", "west", "com", "others"

<service> : "sip", "voice", "video", "vphone" (video-phone),"mon" (monitor), "others"

<subscriber-class> : "gn" (public), "ur" (priority), "ur1" (emergency)

<Reserved1> : digit (0-15)

<physical-interface-id> : digit (0-1023)

<Reserved2> : digit (0-4095)

<sub-interface-id> : digit (0-4095)

<termination-attribute> : "dc" (d.c.), "ac" (access), "bb" (backbone),"mon" (monitor)

<channel> : digit (0-4294967295)

Displaying the Nine-Tier Termination Name Hierarchy

This section describes the show command for the nine-tier termination name hierarchy.

The media-flow-stats show command is extended to include the full-termination ID in the response:

show services sbc service-name dbe media-flow-stats [vrf [global] [ipv4 A.B.C.D [port port-number]]]

Syntax	Description
show services sbc service-name dbe media-flow-stats [vrf [global] [ipv4 A.B.C.D [port port-number]]] Example: RP/0/0/CPU0:router# show services sbc my sbc dbe media-flow-stats vrf vpn3 ipv4 10.1.1.1 port 24000	Lists the statistics about one or more media flows collected on the DBE. •service-name—The SBC service name •(Optional) A.B.C.D—Only display media flows to/from this IPv4 media address •(Optional) port-number—Only display media flows to/from this port

Displaying the Nine-Tier Termination Name Hierarchy: Example

This section provides an example of the reported fields for the show command displaying the nine-tier termination name hierarchy: tcc/voice/gn/0/1/0/1/ac/2

The entry Media flowing = Yes either means that media has been observed flowing on the call within media-timeout period, or the call has failed over within the last media-timeout period, and the SBC has not yet had a chance to observe whether media is flowing or not.

The statistics starting with Rtp are maintained and collected in real time when the command is issued.

Endpoint statistics (beginning with EndPoint) are collected from RTCP packets transmitted by endpoints and are updated as and when these RTCP packets are received. Not all endpoints report RTCP endpoint statistics. Not all endpoints that report RTCP statistics report all the fields shown.
