This Recommendation specifies:
− service plane concept for IP-based services;
− support of IP-based services by ATM;
− attributes for IP transfer capabilities to support IP-based services;
− service level agreement for IP-based services.
By introducing the concept of the service plane, the possible sets of attributes for IP transfer capabilities to support the IP-based services are given.
Figure 1 shows the relationship of this Recommendation with related IP Recommendations.
IP-based services may be supported on IP above any layer 1 and layer 2 transport capable of supporting IP. While Figure 1 shows ATM as the transport mechanism, other underlying transfer mechanisms can be used to provide the same IP-based services. The use of IP over these other transfer mechanisms is described in other Recommendations.
