Handbook of SDP for Multimedia Session Negotiations: SIP and WebRTC IP Telephony

This book on SDP is the first of this kind that attempts to put all SDP related RFCs together with their mandatory and optional texts in a chronological systematic way as if people can use a single "super-SDP RFC" with almost one-to-one integrity from beginning to end to see the big picture of SDP in addition to base SDP functionalities.

這本關於SDP的書籍是第一本試圖將所有與SDP相關的RFC文件以時間順序系統化地整合在一起的書籍，就像人們可以使用一個「超級SDP RFC」從頭到尾以幾乎一對一的完整性來了解SDP的整體情況，除了基本的SDP功能之外。
