Filter Configuration

Comma-separated list of Cassandra node addresses to connect to initially.

The port to use to connect to Cassandra nodes.

The name of the Cassandra keyspace that stores GAA bootstrap information.

The GAA Service Type for this NAF. Defaults to service type 0 (unspecified service type). See 3GPP TS 29.109 Annex B.

The GAA Service Identifier for this NAF. This value is operator-specific. Uniquely identifies a service (such as XCAP) within the operator’s network.

This value has to match the service-id returned by the HSS in the subscriber’s GUSS.

Note that some HSS automatically populate the GUSS service-id with the same value as the GUSS service-type.

Must be an integer value.

The optional NAF Group this NAF belongs to. NAF groups are operator specific. Default is the empty string (no NAF group).

The two policies available for connection/re-connection (reconnection.policy) are:

How long (s) between attempts to connect to the Cassandra DB (constant). Acceptable values are 5s to 60s.

The first delay (s) before attempting to connect to the Cassandra DB (exponential). Acceptable values are 1s to 24s.

Subsequent delay (s) = 2 x previous delay, capped by max delay (s) (exponential). Acceptable values are 16s to 128s.

How long (ms) to establish a new connection to a Cassandra node before giving up.

How long (ms) for a given Cassandra node to answer a query.

True/False/not-set. Whether to enable TCP keepalive. The default, (not-set), means the value used is the default from the underlying Netty transport.

True/False/not-set. Whether reuse-address is enabled. The default, (not-set), means the value used is the default from the underlying Netty transport.

The linger-on-close timeout. The default, (-1 == not set), means the value used is the default from the underlying Netty transport.

Whether to disable Nagle’s algorithm.

Sets a hint to the size of the underlying buffers for incoming network I/O. The default, (-1 == not set), means the value used is the default from the underlying Netty transport.

Sets a hint to the size of the underlying buffers for outgoing network I/O. The default, (-1 == not set), means the value used is the default from the underlying Netty transport.

Select the load-balancing approach to use. Allowed values include: round-robin, dc-aware-round-robin, latency-aware-round-robin, latency-aware-dc-aware-round-robin. A value of use-default uses the driver default.

How much worse the average latency of a node must be compared to the fastest performing node for it to be penalized. Must be greater than 1.0. A value of 0 means use the driver default.

Dictates the weight of a latency measurement to previous measurements in average latency. The value must be greater than 0. A value of 0 means use the driver default.

If SSL should be used (using jdk built-in engine).

If SSL should be used (defer to the Netty layer).

The number of times the same nonce can be used. Must be greater than 0.

The lifetime of a nonce, in milliseconds.

The maximum number of nonce records to keep in memory. Must be greater than 0.

The storage mechanism used for nonces. Can be local for storage in memory only or cassandra for storage in Cassandra.

The name of the cassandra keyspace used to store nonces when cassandra is set for sentinel.gaa.nonce-storage. Defaults to opencloud_nonce_info

The comma-separated list of IP addresses which represent the trusted network interface(s) of the NAF Authentication Filter. Requests received on any of these IP addresses will not be required to supply valid authentication credentials.

This allows the NAF Authentication Filter to handle requests from internal clients that do not support the authentication protocols.

The comma-separated list of URL path prefixes for which authentication should always be enforced. This has precedence over the sentinel.gaa.trusted-ips setting.
