Introduction
• IPV4• IPV6• VOIP• IPV4 to IPV6• Migration of VOIP to IPV6
Introduction to IPV6
• Expanded addressing capabilities• Header format simplification• Improved support for extension headers• Flow labeling capability• Authentication and privacy
IPV6 Header Format
IPV6 Header Format
• Version Field• Traffic Class• Flow Label• Payload Length• Next Header• Hop Limit• Source and Destination Address
MIGRATING TO IPV6
• STAGE 1: IPV4 only networks.• STAGE 2:IPV6 islands connected through IPV4
network.• STAGE 3:Interconnection of IPV4/IPV6
networks.• STAGE 4:IPV4 islands connected through IPV6
network.• STAGE 5:IPV6 only networks.
Interconnecting IPV6 and IPV4 networks
TRANSITION METHODOLOGIES
• IPV4/IPV6 DUAL STACKS• TUNNELING
Tunneling mechanism for inter working IPV4& IPV6
Several types of IPV6-to-IPV4 tunnels
• MANUALLY CONFIGURED TUNNELS(MCT)• DYNAMIC 6TO4 TUNNELS• TEREDO TUNNELING
TEREDO TUNNELING
• Teredo Clients• Teredo Servers• Teredo Relays
Structure Of IPV6 Teredo address
TRANSLATING BETWEEN IPV4 AND IPV6 WITH NAT-PT
• COMM… IPV4 ONLY N/W WITH IPV6-ONLY
VOIP
• Typical Interconnection of VOIP and PSTN
Characteristics of several voice codecs
Voip Protocols
• MGCP(Media gateway control protocol)• SIP(Session Initiation Protocol)• H.323
Media Gateway Control Protocol
Typical MGCP EnvironmentMGCP Components:
• Endpoints• Gateways• Call Agents
SESSION INITIATION PROTOCOL
• Working Principle of SIP at a glance• Proxy Server• DNS Server• Location Server
Basic SIP trapezoid
Basic SIP flow label
H.323-PROTOCOL AT A GLANCE
• COLLECTION OF PROTOCOLS• Q.931• H.225• H.245
Protocol Relationships In H.323
Gatekeeper Routed Call Model In H.323
OTHER ISSUES
• DOMAIN NAMING SYSTEM IN IPV6• IPV6 APPLICATION TRANSITION ISSUES
IPV6 APPLICATION TRANSITION ISSUES
• SESSION INITIATION PROTOCOL(SIP) AND IPV6
• APPLICATIONS WITH IPV6 MIGRATION
IPV6/IPV4 network with Session Initiation Protocol
