clearwater.Bono:
description: >-
Clearwater edge proxy.
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.

clearwater.Sprout:
description: >-
Clearwater SIP router.
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).

description: >-
Clearwater HSS cache.
Homestead provides a web services interface to Sprout for retrieving authentication
credentials and user profile information. It can either master the data (in which case it
exposes a web services provisioning interface) or can pull the data from an IMS compliant HSS
over the Cx interface. The Homestead nodes themselves are stateless - the mastered / cached
subscriber data is all stored on Vellum (via Cassandra's Thrift interface).
In the IMS architecture, the HSS mirror function is considered to be part of the I-CSCF and
S-CSCF components, so in Clearwater I-CSCF and S-CSCF function is implemented with a
combination of Sprout and Dime clusters.

clearwater.Ralf:
description: >-
Clearwater CTF.
Ralf provides an HTTP API that both Bono and Sprout can use to report billable events that
should be passed to the CDF (Charging Data Function) over the Rf billing interface. Ralf is
stateless, using Vellum to maintain the long lived session state and run the timers necessary
to enable it to conform to the Rf protocol.

clearwater.Vellum:
description: >-
Clearwater state store.
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.

clearwater.Homer:
description: >-
Clearwater XDMS.
Homer is a standard XDMS used to store MMTEL service settings documents for each user of the
system. Documents are created, read, updated and deleted using a standard XCAP interface. As
with Homestead, the Homer nodes use Vellum as the data store for all long lived data.

Ellis is a sample provisioning portal providing self sign-up, password management, line

production Clearwater deployments (it is not easy to horizontally scale because of the MySQL
underpinnings for one thing) but to make the system easy to use out of the box.
