Serval Infrastructure
|
||
|
|
=====================
|
||
|
|
|
||
|
|
Based on design discussions between Andrew Bettison and Jeremy Lakeman in
|
||
|
|
September, 2012.
|
||
|
|
|
||
|
|
In practice, these three services are built into a single daemon that can be
|
||
|
|
deployed into a mesh at many points.
|
||
|
|
|
||
|
|
Serval Directory Service (SDS)
|
||
|
|
------------------------------
|
||
|
|
|
||
|
|
SDS is a registry that associates subscriber names and phone numbers (DID) with
|
||
|
|
subscriber identities (SID). Any subscriber may potentially register its
|
||
|
|
details with an SDS, and an SDS may also have its own source of registry
|
||
|
|
entries, such as an associated Asterisk exchange. SDS allows the decentralised
|
||
|
|
DNA Lookup architecture to be supplemented with infrastructure, ie, mesh nodes
|
||
|
|
offering persistent services or bridges out of the mesh.
|
||
|
|
|
||
|
|
* Maps DID or Name → SID
|
||
|
|
* Responds to DNA Lookup requests
|
||
|
|
* Keeps registry of DNA entries (SID-DID-name)
|
||
|
|
* Accepts registrations and renewals of DNA entries
|
||
|
|
* Collects and caches DNA responses from local networks
|
||
|
|
|
||
|
|
Serval Internet Location Service (SILS)
|
||
|
|
---------------------------------------
|
||
|
|
|
||
|
|
* Maps SID → IP address + port number (`sockaddr_in`)
|
||
|
|
* Keeps a SIR (Subscriber Internet Registry)
|
||
|
|
* Accepts registrations (signed)
|
||
|
|
* Responds to location requests
|
||
|
|
|
||
|
|
Serval Internet Routing Service (SIRS)
|
||
|
|
--------------------------------------
|
||
|
|
|
||
|
|
* Forwards MDP packets to MDP nodes listening on IP addresses/ports
|
||
|
|
* Uses SILS to resolve destination IP addresses/ports
