Document: draft-ietf-tsvwg-rfc5405bis-16
Title: UDP Usage Guidelines
Reviewer: S. Moonesamy
Review Date: August 5, 2016
IETF Last Call Date: May 17, 2016

Summary: This draft is almost ready for publication as an Best Common 
Practice RFC.

The document is applicable to application protocol designers instead 
of application developers as the recommendation about UDP would have 
to be part of the application protocol for ease of implementation.

Major issues: None


Minor issues:

In Section 3.1.9:

   "Applications intended for the Internet SHOULD NOT assume that
    QoS mechanisms are supported by the networks they use, and
    therefore need to provide congestion control, error recovery,
    etc. in case the actual network path does not provide
    provisioned service."

Is there a case when an application intended for use on the Internet 
can assume that QoS mechanisms are supported throughout both ends of 
the connection?

Nits:

In Section 1:

   "In such cases, it is RECOMMENDED that application designers cite
    the respective section(s) of this document in the technical
    specification of their application or protocol and explain
    their rationale for their design choice.'

The RFC 2119 key word is used before its definition in Section 2.

Regards,
S. Moonesamy
