Abstract (EN):
A new SIP standard based on peer to peer paradigm allows the keeping of user localization information in a decentralized way, adding flexibility to real-time mobile communications. Despite specification of terminal mobility in P2PSIP, handover procedures intransport-layer have better performance when compared with solutions in application-layer of Internet. SCTP transport protocol supports handover and a partial reliable communication service. Putting together P2PSIP and SCTP extensions, an end-to-end architecture can be proposed, aimed at the support of real-time multimedia applications with mobility requirements. © 2010 ACADEMY PUBLISHER.
