The IP design issues

• multi-service requirements
• (voice, video, data) of one
• network
• unpredictable usage
• - due to application development
• - due to user/customer behaviour

IPv6 and P702
Extended address space allowing hierarchical
pre-fix based routing (smaller routing tables),
and overcoming future address shortages. A
standardized header format and size making it
easier to process packets Header and payload
compression Standards track QoS and
differential service features. Mandated
security (authentication, integrity,
confidentiality and key man). Mandated
Auto-configuration in both stateful and stateless
modes Updated routing protocols (RIPv6, OSPFv6,
BGP4, IDRPv6). Multi-homing possibilities.
Dual stack migration strategy ensuring
interoperability with IPv4 Simplified mobility
supporting mobile and nomadic scenarios
