Operational Constraints
Cross-layer Control Loops
Cross-layer (and cross-over/underlay), cross-plane
Composability
Composable protocols, etc.
Virtualisation of Ressources
- make usage of ressources (redundant and/or diverse) transparent for all hosts
- (might be used for load balancing, too)
- self-configuration of primary and backup service providers
- mutual control of correct functionality
- fast switch over in case of failure
- no failure notification to non-service hosts neccessary
- (synchronisation of service instances, if applicable)
- applicable for name resolvers, inter-compartment forwarders, etc.
This is part of the redundancy and diversity principles
Late State Creation
- never create local state for unknown/untrusted/unauthenticated communication peers
- use stateless cookies for state encapsulation
- define header fields for cookie transport
- define interval length for key switching
- applicable for key exchange protocols, connection oriented protocols, etc.
This is part of the self-protection principle
Programmable Intelligent Nodes
Programmable nodes with cognition:
- reactive: context aware to react to environment (used for detection)
- deliberative: planning and reasoning (used for remediation and recovery)
- reflective: self-observation and future behaviour modification
