An SfaApi instance is a basic xmlrcp service
augmented with the local cryptographic material and hrn
- It also has the notion of neighbour sfa services
- as defined in /etc/sfa/{aggregates,registries}.xml
- It has no a priori knowledge of the underlying testbed
+
+ It also has the notion of its own interface (a string describing
+ whether we run a registry, aggregate or slicemgr) and has
+ the notion of neighbour sfa services as defined
+ in /etc/sfa/{aggregates,registries}.xml

+ Finally it contains a cache instance

+ It gets augmented by the generic layer with
