Configuration
The BNG Blastert configuration is presented as a JSON file. This configuration must include at least one interface function.
{
"interfaces": {
"network": {
"interface": "eth2",
"address": "10.0.0.10/24",
"gateway": "10.0.0.2"
}
}
}
In order to minimize the size of this configuration, you have the option to relocate the stream definitions to a separate file. However, it’s important to note that both the streams specified in the main configuration file and the additional streams configuration file will be applied. This approach proves particularly beneficial when conducting tests that involve an extensive number of traffic streams, numbering in the millions. By separating the streams into distinct files, you can maintain a more organized and manageable configuration while ensuring that the combined streams are effectively utilized in your testing scenarios. This flexibility in configuration empowers you to handle large-scale traffic simulations with ease.
bngblaster -C config.json -T streams.json
Variables
Some configuration attributes like username, password, agent-remote-id, agent-circuit-id, or cfm-ma-name support variable substitution. The variable {session-global} will be replaced with the actual session-id starting from 1 and incremented for every new session. The variable {session} is incremented per-interface section. The variables {outer-vlan} and {inner-vlan} will be replaced with the corresponding VLAN identifier or 0 if not defined. The two variables {i1} and {i2} are configurable per-interface sections with user-defined start values and steps.
{
"username": "user{session-global}@rtbrick.com",
"agent-circuit-id": "0.0.0.0/0.0.0.0 eth {outer-vlan}:{inner-vlan}",
"agent-remote-id": "DEU.RTBRICK.{i1}",
"i1-start": 10000,
"i1-step": 2
}

Stream traffic rate in packets per second.
This value supports also float numbers like 0.1 or 2.5.
In example 0.1 means one packet every 10 seconds.
Default: 1.0
|
bps |
Stream traffic rate in bits per second (layer 3).
PPS has priority over bps where the second is only a helper
to calculate the actual PPS based on given bps and length.
The resulting rate in bps is the layer 3 rate because length
is also the layer 3 length (IP header + payload).
It is also supported to put the capital letters K (Kilo),
M (Mega) or G (Giga) in front of bps for better readability.
For example,
"Gbps": 1which is equal to
"bps": 1000000000. |

Optionally overwrite PPS in upstream to support bidirectional
streams with different rates for upstream and downstream.
|
bps-upstream |
Optionally overwrite bps in upstream to support bidirectional
streams with different rates for upstream and downstream.
|
setup-interval |
Set optional setup interval in seconds. If set, sent max 1
packet per setup interval until stream becomes verified.

For bidirectional streams (direction both), this requires both
directions to be verified.

Access-Line
This feature is designed to simulate various access line attributes defined by the Broadband Forum, which are subsequently employed in protocols such as PPPoE discovery, DHCPv4, and DHCPv6 packets.
The values defined in access-line section apply globally but can be overwritten in the access interface section. The strings agent-remote-id, agent-circuit-id, and access-aggregation-circuit-id support variable substitution.

Attribute | Description |

Attributes with values set to zero will be automatically excluded, making it impossible to send attributes with a zero value. In other words, any attribute that has a value of zero will not be included in the corresponding packets.
In the context of DHCPv6, access line attributes, as well as Agent-Remote-Id or Agent-Circuit-Id, are exclusively permitted in DHCPv6 relay-forward messages as dictated by RFC. By default, BNG Blaster includes these attributes in other DHCPv6 messages, even if this deviates from RFC guidelines. Therefore, the DHCPv6 configuration section provides the option to either disable access-line attributes or, as an alternative, enable LDRA (Lightweight DHCPv6 Relay Agent).
Access-Line-Profiles
Attributes within the access-line-profiles are treated analogous to those within the access-line section but they provide the capability to apply different profiles to each access interface.

value chosen indicates the maximum number of seconds
that may elapse between the receipt of successive PDUs
from the LDP peer on the session TCP connection. The
keepalive timeout is reset each time a PDU arrives. The

calculated by using the effective keepalive time divided
by 3. Assuming an effective keepalive time of of 15
seconds results in a keepalive interval of 5 seconds.
