#Examples for working with HP Cloud Networking Service
The HP Cloud provides networking support using two abstractions: a model layer and a request layer. Both layers are detailed below.

**Note:** The networking functionality works with HP Cloud version 13.5 but is not available in version 12.12.

The code samples on this page can be executed from within a Ruby console (IRB):

        irb

## Connecting to the Service

To connect to the HP Cloud Networking Service, follow these steps:

1. Enter IRB

        irb

2. Require the Fog library

        require 'fog'

3. Establish a connection to the HP Cloud Networking service

        conn = Fog::HP::Network.new(
               :hp_access_key  => "<your_ACCESS_KEY>",
               :hp_secret_key => "<your_SECRET_KEY>",
               :hp_auth_uri   => "<IDENTITY_ENDPOINT_URL>",
               :hp_tenant_id => "<your_TENANT_ID>",
               :hp_avl_zone => "<your_AVAILABILITY_ZONE>",
               <other optional parameters>
               )

**Note**: You must use the `:hp_access_key` parameter rather than the now-deprecated  `:hp_account_id` parameter you might have used in previous Ruby Fog versions.

You can find the values the access key, secret key, and other values by clicking the [`API Keys`](https://console.hpcloud.com/account/api_keys) button in the [Console Dashboard](https://console.hpcloud.com/dashboard).
