Low Packet Loss

The low packet loss Intent identifies the best path between a given source and destination pair based on the lowest packet loss. This intent is ideal for applications requiring a reliable connection between two points.

Network Topology

The network topology below, with the associated packet loss values, is used to demonstrate this intent. The packet loss impairments were applied using the Lab Impairment Script

Example Scenario

In this example, Host-A (acting as a client) requests a low-packet-loss path to Host-B (acting as a server). The HawkEye controller calculates the optimal path based on the lowest packet loss between the two hosts.

          - intent: low-packet-loss

API Request

The low packet loss request is saved single intent folder. The JSON request format is as follows:

{
    "ipv6_source_address": "2001:db8:a::10",
    "ipv6_destination_address": "2001:db8:b::10",
    "intents": [
        {
            "type": "INTENT_TYPE_LOW_PACKET_LOSS"
        }
    ]
}

Result

The result includes the following SID List, ensuring the lowest packet loss path between the two hosts:

• fc00:0:1:0:1::
• fc00:0:2:0:1::
• fc00:0:6:0:1::
• fc00:0:8:0:1::
• fc00:0:b:0:1::

The packets are routed through the following devices: HOST-A -> SITE-A -> XR-1 -> XR-2 -> XR-6 -> XR-8 -> SITE-B -> HOST-B
