Host Media Processing Software Release 4.1LIN Release Guide
Features
If the Dialogic
®
HMP Software 4.1LIN is installed on a media server (MS), the MSML
media server software enables a remote client, also known as an application server (AS),
to control media resources.
The MSML media server software is based on the evolving MSML language, as defined in
the IETF RFC 5707.
The connection between the AS and MS is established using the SIP protocol; thereafter
media control commands/responses (in the form of MSML control syntax) are exchanged
in SIP messages, such as the INFO request message or the 200 OK response message.

3.5 New IPv6 Support
Dialogic
®
Host Media Processing Software Release 4.1LIN introduces support for Internet
Protocol Version 6 (IPv6) for open media connections.
The key features of IPv6 are:
• Simplified header format
• Expanded addressing capabilities (128 bits long, compared to 32 bits in IPv4)
• Stateless and stateful address configuration
• Built-in security support
• Improved support for quality of service (QoS)
• New protocol for neighboring node interaction
• Improved support for extensions and options
Applications can be configured to run in a pure IPv4, IPv6, or a mixed (both IPv4 and IPv6
addressing) network environment.
Limitations
Support for IPv6 addressing with Dialogic
®
HMP 4.1LIN software is implemented in
phases. The initial phase, Phase 1, provides IPv6 support for bearer channel (multimedia)
connections as well as for OA&M interfaces (CLI). Known limitations for Phase 1 are:
• IPv6 supports Audio/Video only. No Fax or NbUP support is provided.
• CLI (Telnet) may only be reached via an IPv4 address.
3.6 New Virtualization Support
