4.8. Transport LBT-RM Network Options

The following illustration shows where the various options are applied. Note that for a multi-homed LBT-RM source, the interface LBT-RM multicast resolver interface specified with resolver_multicast_interface will be used as the source for LBT-RM.

Figure 4-4. LBT-RM network options

4.8.1. transport_lbtrm_destination_port (source)

The UDP destination port used for this Topic when LBT-RM is used.

Scope: source
Type: lbm_uint16_t
Default value: 14400
Byte order: Network
When to Set: Can only be set during object initialization.

4.8.2. transport_lbtrm_multicast_address (source)

The preferred multicast address for this Topic when LBT-RM is used. If 0.0.0.0 (INADDR_ANY), the context will attempt to find one in the given multicast address range.

Scope: source
Type: struct in_addr
Default value: 0.0.0.0 (INADDR_ANY)
When to Set: Can only be set during object initialization.

4.8.3. transport_lbtrm_multicast_address_high (context)

Multicast address used as the highest value to assign LBT-RM sessions to.

Scope: context
Type: struct in_addr
Default value: 224.10.10.14
When to Set: Can only be set during object initialization.

4.8.4. transport_lbtrm_multicast_address_low (context)

Multicast address used as the lowest value to assign LBT-RM session to.

Scope: context
Type: struct in_addr
Default value: 224.10.10.10
When to Set: Can only be set during object initialization.

4.8.5. transport_lbtrm_source_port_high (context)

Highest port number value used for LBT-RM source sessions used for unicast NAK processing. NAKs are sent back to this port number for processing and retransmission generation. Each LBT-RM session must use a unique port value. Note that this does not control the UDP source port on the outbound LBT-RM stream.

Scope: context
Type: lbm_uint16_t
Default value: 14399
Byte order: Host
When to Set: Can only be set during object initialization.

4.8.6. transport_lbtrm_source_port_low (context)

Lowest port number value used for LBT-RM source sessions used for unicast NAK processing. NAKs are sent back to this port number for processing and retransmission generation. Each LBT-RM session must use a unique port value. Note that this does not control the UDP source port on the outbound LBT-RM stream.

Scope: context
Type: lbm_uint16_t
Default value: 14390
Byte order: Host
When to Set: Can only be set during object initialization.
