Subject [2/2] incubator-ariatosca git commit: ARIA-321 Provide Clearwater IMS example
Date Fri, 28 Jul 2017 03:07:48 GMT
ARIA-321 Provide Clearwater IMS example

* Allows capabilities, interfaces, and properties to override parent
definition types only if the new type is a descendant of the overridden
type
* Fix bugs in model instrumentation (to allow ctx access to capability
properties and complex values)
* Fix to get_property intrinsic function
* Don't let scalar values be negative
* Doc fixes related to ARIA-277

+
+      The Bono nodes form a horizontally scalable SIP edge proxy providing both a SIP IMS Gm
+      compliant interface and a WebRTC interface to clients. Client connections are load balanced
+      across the nodes. The Bono node provides the anchor point for the client's connection to the
+      Clearwater system, including support for various NAT traversal mechanisms. A client is
+      therefore anchored to a particular Bono node for the duration of its registration, but can
+      move to another Bono node if the connection or client fails.
+
+      Clients can connect to Bono using SIP/UDP or SIP/TCP. Bono supports any WebRTC client that
+      performs call setup signaling using SIP over WebSocket.
+
+      Alternatively, Clearwater can be deployed with a third party P-CSCF or Session Border
+      Controller implementing P-CSCF. In this case Bono nodes are not required.

+
+      The Sprout nodes act as a horizontally scalable, combined SIP registrar and authoritative
+      routing proxy, and handle client authentication and the ISC interface to application servers.
+      The Sprout nodes also contain the in-built MMTEL application server. SIP transactions are load
+      balanced across the Sprout cluster, so there is no long-lived association between a client and
+      a particular Sprout node. Sprout does not store any long-lived data itself and instead uses
+      web service interfaces to Homestead and Homer to retrieve HSS configuration such as
+      authentication data/user profiles and MMTEL service settings APIs to Vellum for storing
+      subscriber registration data and for running timers.
+
+      Sprout is where the bulk of the I-CSCF and S-CSCF function resides, with the remainder
+      provided by Dime (and backed by the long-lived data stores on Vellum).

+
+      Vellum is used to maintain all long-lived state in the deployment. It does this by running a
+      number of cloud optimized, distributed storage clusters.
+
+      - Cassandra. Cassandra is used by Homestead to store authentication credentials and profile
+      information, and is used by Homer to store MMTEL service settings. Vellum exposes Cassandra's
+      Thrift API.
+
+      - etcd. etcd is used by Vellum itself to share clustering information between Vellum nodes and
+      by other nodes in the deployment for shared configuration.
+
+      - Chronos. Chronos is a distributed, redundant, reliable timer service developed by
+      Clearwater. It is used by Sprout and Ralf nodes to enable timers to be run (e.g. for SIP
+      Registration expiry) without pinning operations to a specific node (one node can set the timer
+      and another act on it when it pops). Chronos is accessed via an HTTP API.
+
+      - Memcached / Astaire. Vellum also runs a Memcached cluster fronted by Astaire. Astaire is a
+      service developed by Clearwater that enabled more rapid scale up and scale down of memcached
+      clusters. This cluster is used by Sprout and Ralf for storing registration and session state.
