Gateway control protocol: Guidelines on the use of ITU-T H.248 capabilities for transport security in TLS networks in ITU-T H.248 profiles
|Publication Date:||1 October 2014|
Transport layer security (TLS) is a cryptographic protocol that provides secure communication between two IP transport endpoints. This Recommendation:
- describes example use cases;
- defines the basic requirements to secure the bearer path connection between a media gateway (MG) and a remote endpoint through TLS;
- references suitable ITU-T H.248 signalling capabilities in terms of ITU-T H.248 packages as defined by other ITU-T H.248.x-series Recommendations; and
- defines a protocol solution in style of a generic profile (which covers usage information of package(s) and procedures) as a guideline for final profile specifications.
The primary audience of this Recommendation are therefore authors of ITU-T H.248 profile specifications, which aim to support a particular network use case with TLS encrypted bearer traffic (based on the example use cases from Appendix II of [ITU-T H.248.90]).This Recommendation is organized as follows:
- principal requirements are subject of clauses 6 to 9, categorized in capabilities with regards to the mode of operation of a MG, TLS profile concepts and TLS protocol specific requirements;
- profile specification guidelines in clause 10 (which follows the profile structure of the ITU-T H.248 profile template according to [ITU-T H.248.1]).
