SDP is a data format rather than a protocol:

Session description
v= (protocol version)
o= (owner/creator and session identifier).
s= (session name)
i=* (session information)
u=* (URI of description)
e=* (email address)
p=* (phone number)
c=* (connection information - not required if included in all media)
b=* (bandwidth information)
z=* (time zone adjustments)
k=* (encryption key)
a=* (zero or more session attribute lines)

Example:

v=0
o=sisalem 28908044538 289080890 IN IP4 193.175.132.118
s=SIP Tutorial
e=sisalem@fokus.gmd.de
c=IN IP4 126.16.69.4
t=28908044900 28908045000
m=audio 49170 RTP/AVP 0 98
a=rtpmap:98 L16/11025/2
