The Need for IP Signaling Protocol The Need for IP Signaling Protocol
(Call setup and teardown, etc.) (Call setup and teardown, etc.)
•Just like Signaling System 7(SS7) in the circuit-switched world, there is a call control or call processing technique in packet switching that maps telephone numbers or user names to IP source/destination addresses. •Call control is implemented by call-control software running on servers (a.k.a. gatekeepers). •The first call control protocol for VoIP was H.323( adopted by ITU). H323 provides multimedia communication for voice video & data, and isimplemented by applications like Microsoft NetMeeting.•H323 was followed by the IETF Session Initiation Protocol (SIP)based on HTTP, which deliver faster call-establishment times and integration with Internet multimedia applications.•Most recently, Telcordia(formerly Bellcore), Level 3, and Cisco Systems announced the Media Gateway Control Protocol (MGCP) that addresses the control of media gateways.•The ITU and the IETF have joined forces to produce a new standard. This new standard is known as Megacowithin IETF and H.248within ITU.

Multi-protocol Label Switching (MPLS)Concept, Architecture, Applications

What is MPLS? What is MPLS?
•MPLS Technology simply appends a tag/label/new field into a frame or a packet•These label extensions allow the insertion of additional information thus enabling more intelligence & new functionality that can be used to provide better forwarding decisions and new IP services•For example, MPLS labels allows the Switch or Router to perform additional services (beside forwarding) like Qos, L2 VPN & Traffic Engineering (RSVP)•The MPLS forwarding algorithm provides simpler and faster Network Forward Processing than the traditional IP Forwarding Algorithm (i.e., faster networks)•It is possible to implement tag switching over virtually any media type including LL, PPP, Ethernet ATM, FR, HDLC, optical, etc.TE LabelIGP LabelVPN LabelInner LabelOuter LabelIP Packet HeaderProvider ProvisionedVPNsMPLSTraffic EngineeringRSVPIP+ATMIntegrationNetwork InfrastructureIP+OpticalMPLSIntegrationAny Transport Over MPLS
