SDP Compression Algorithm for WebRTC: ESDiPi

Adem Atalay, Doğaç Başaran
Abstract—In Voice over IP or WebRTC technologies, the communicating parties use Session Description Protocol (SDP) for negotiation of the session and media capabilities to establish the connection. A typical SDP is a simple text data that has a length of approximately 3000 bytes however this size is not so suitable for some applications i.e. mobile applications. Standard compression algorithms such as G-Zip, 7-Zip, are usually applied to reduce the SDP sizes. Such approaches do not consider the specific structure of the data to be compressed hence better compression ratios aretheoretically possible. In this work, we propose a compression algorithm based on Lempel-Ziv (LZ77) lossless coding scheme combined with SDP packet structure. Experimental results reveal that our approach reaches much better compression ratios than some widely used compression algorithms.

Index Terms—WebRTC, session description, compression, Lempel-Ziv.
