英文名称：Network address translator and firewall device determination in ITU-T H.323 systems (Study Group 16)
发布日期：2009
标准简介：This Recommendation defines the capability and procedures for determining whether an endpoint is located behind a network address translator (NAT) or firewall (FW) and to determine the characteristics of the NAT/Firewall device. This feature detects the NAT/Firewall characteristics in order to allow a gatekeeper to determine whether it is possible to stream media directly between two endpoints. If used in conjunction with [ITU-T H.460.24], the scalability of [ITU-T H.460.18]/[ITU-T H.460.19] may be extended to allow media to flow directly between ITU-T H.323 endpoints, thus avoiding the necessity to proxy media through an ITU-T H.460.19 server.
