High Bandwidth Intent

The high bandwidth intent identifies the best path between a given source and destination pair based on the highest available bandwidth. The available bandwidth equals the maximum link bandwidth - the consumed bandwidth. This intent is ideal for applications requiring high bandwidth.

Network Topology

The network topology below, with the associated rate limits, is used to demonstrate this intent. The bandwidth/rate impairments were applied using the Lab Impairment Script. Since, the there is almost no traffic in the network, the path should follow the path including the highest bandwidth links.

Hawkv6 Network with Bandwidth Impairments

Example Scenario

In this example, Host-A (acting as a client) requests a high bandwidth path to Host-B (acting as a server). The HawkEye controller calculates the optimal path based on the highest available bandwidth between the two hosts.

HawkWing Configuration

---
client_ipv6_address: 2001:db8:a::10
hawkeye:
  enabled: true
  address: 2001:db8:e5::e
  port: 10000
services:
  webserver-b:
    ipv6_addresses:
      - 2001:db8:b::10
    applications:
      - port: 80
        intents:
          - intent: high-bandwidth

API Request

The high bandwidth 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:c::10",
    "intents": [
        {
            "type": "INTENT_TYPE_HIGH_BANDWIDTH"
        }
    ]
}

Result

The result includes the following SID List, ensuring the path with the highest available bandwidth:

  • 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 -> SITE-B -> HOST-B
