Thanks Ari for the review. Regarding the abstract, please let me know if
the below introductory paragraph captures what is needed.

"The Session Description Protocol (SDP) provides mechanisms to
       describe attributes of multimedia sessions and of individual media
       streams (e.g., Real-time Transport Protocol (RTP) sessions) within a
       multimedia session. Typically media associated with individual
       media descriptions ("m=" lines) represent separate RTP Sessions
       and thus carried over individual underlying transport layer flows.
       For scenarios
       where SDP is used to negotiate the usage of single 5-tuple for
       sending and receiving media associated with multiple media
descriptions, it is required to understand the semantic implications of the
 attributes associated with the RTP Media Streams multiplexed over a
       single underlying transport layer flow"

Thanks
Suhas
