Domains (multiple collaborating service providers) create service offerings between pairs of edge nodes that interconnect with other domains in the network. The service offerings may specify the available bandwidth, quality of service, reliability, available security, price, subscriber and service contextual specific and other SLA information. When a new service is to be created, the service definition is used along with information about the available service offerings to determine a set of networks to implement the service. Information associated with the service offerings may be flooded to all other networks. Alternatively, the service offering information may be provided to a trusted third party (SLA broker) which may provide SLA services on the network to select sets of domains to implement inter-domain services, and may also proxy to set up the service for the SLA requesting party. A hybrid approach may also be used wherein some SLA information is flooded and other information is retained in secret and provided only to the SLA broker.
