SDP Compression Algorithm for WebRTC: ESDiPi

Adem Atalay, Doğaç Başaran
2016 International Journal of Computer and Electrical Engineering  
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.  ...  Standard compression algorithms such as G-Zip, 7-Zip, are usually applied to reduce the SDP sizes.  ...  Session description protocol (SDP) is a text data that contains streaming media initialization parameters.  ...

The Devil is in the Detail: SDP-Driven Malformed Message Attacks and Mitigation in SIP Ecosystems

Zisis Tsiatsikas, Georgios Kambourakis, Dimitris Geneiatakis, Hua Wang
2019 IEEE Access  
INDEX TERMS Covert channel, DoS, malformed messages, session description protocol, session initiation protocol.  ...  In an effort to fill this gap, this paper concentrates on the detection of DoS attacks, which, instead, capitalize on the session description protocol (SDP) part of SIP requests.  ...  However, what is largely neglected is that similar attacks may take advantage of the Session Description Protocol (SDP) [1] part of a SIP message.  ...

A Multimedia-Specific Approach to WS-Agreement

Wilfried Jouve, Julien Lancia, Charles Consel, Calton Pu
2006 2006 European Conference on Web Services (ECOWS'06)  
This work relies on an existing protocol for multimedia negotiation, widely used in networking and telecommunications, named Session Description Protocol.  ...  This protocol is used as a framework to cover a variety of media (audio, video, images...).  ...  An SDP description consists of a session-level description followed by optionally several media-level descriptions.  ...

A SIP-Based Network QoS Provisioning Framework for Cloud-Hosted DDS Applications [chapter]

Akram Hakiri, Aniruddha Gokhale, Douglas C. Schmidt, Berthou Pascal, Joe Hoffert, Gayraud Thierry
2011 Lecture Notes in Computer Science  
To distinguish the DDS traffic from other best-effort traffic in the cloud environment, our approach uses the COPS-DRA protocol as a generic protocol for automatic service-level negotiation and the integration  ...  A promising solution to this problem is to integrate DDS with the Session Initiation Protocol (SIP), which is an IP-based signaling protocol that supports real-time applications involving voice, video,  ...  Multimedia sessions can be described using the Session Description Protocol (SDP) [12] .  ...

Signaling to Establish the Connection between Diverse Devices in WLAN

J. T., A. Chandrasekar, D. Frederick
2017 International Journal of Computer Applications  
The media signaling requires a dedicated session description and can be provided by SIP or RTSP.  ...  As the IMS provides session establishment, QoS parameter negotiation, authentication and accounting it is an overlay architecture well qualified for session signaling concerning video in everywhere scenarios  ...  SIP Session negotiation can occur using Session Description Protocol (SDP) to find out if the other peer is reachable and if it is willing to establish the connection.  ...

Integration of Multipath Transmission into the IMS Framework

2017 KSII Transactions on Internet and Information Systems  
The framework transforms original two-party session negotiation into three-party session negotiation that supports participants to negotiate multipath transmission capacity and path information by signaling  ...  Based on existing IETF standards, SIP and SDP are scalable to support these functions. Finally, the proposed framework is fully implemented on open source platform and examined by experiments.  ...  Part of an SDP session description offer is shown below.  ...

Design of SIP transformation server for efficient media negotiation

Sangheon Pack, Eun Kyoung Paik, Yanghee Choi, Petros Mouchtaris
2001 Voice Over IP (VoIP) Technology  
To establish a VoIP session in this case, diversity problems must be resolved by media negotiation mechanism.  ...  It takes only 1.5 round trip times to negotiate two different media types while the standard media negotiation mechanis m takes 2.5 round trip times.  ...  A SIP message is able to have a body part in Session Description Protocol (SDP) [13] .  ...

The need for third-party call control

Tsun-Chieh Chiang, Vijay K. Gurbani, John B. Reid
2002 Bell Labs technical journal  
The evolution of networks and services that has driven the need for 3PCC capabilities is examined along with some of the new service concepts that may make use of 3PCC.  ...  A corresponding IETF protocol, the session description protocol (SDP) [4] , is used to define the media types supported by a SIP session and SDP information is transferred/negotiated between SIP endpoints  ...  To this end, SIP is designed to separate the negotiation of the media used in a session from the signaling involved in establishing the session.  ...

Second, securing the call itself, i.e. securing the Real Time transport Protocol (RTP) media session over the User Datagram Protocol. Security for RTP Media is provided at two different layers.  ...  This IPSec cryptographic processing at caller end makes it unable to send and receive the RTP media packets at the beginning of the RTP session. This situation is called as call clipping.  ...  In states that this part of MIME contains the SDP data used for negotiating media capabilities.  ...
