1. NETWORK CONNECTIVITY USE CASES AT CARRIER / SERVICE PROVIDERS Avi.vachnis@alcatel-lucent.com CloudBand June 2014

2. USE CASES As an application architect I’d like to model my application and network topology as follows:

3. TOSCA SIMPLE PROFILE YAML - NETWORK NODE TYPE node_types: tosca.nodes.Network: derived_from: tosca.nodes.Root properties: ip_version: type: integer required: true cidr: type: string required: false start_ip: type: string required: false # continue at the right # continue… end_ip: type: string required: false gateway: type: string required: false default: true attributes: segmentation_id: type: string description: VLAN ID to be set in runtime

4. TOSCA SIMPLE PROFILE YAML - PORT NODE TYPE node_types: tosca.nodes.Port: derived_from: tosca.nodes.Root properties: network_id: type: string required: false description: network ID (required if network_name is not provided) network_name: type: string required: false description: network name (required if network_id is not provided) order: type: integer required: true description: The order of the network interface default: 1  zero based is prefered constraints: - greater_than: 0 attributes: ip_address: type: string relationship_types: tosca.relationships.LinkedTo: short_name: link derived_from: tosca.relationships.DependsOn valid_targets: [ tosca.capabilities.Linkable ] capability_types: tosca.capabilities.Linkable: derived_from: tosca.capabilities.Feature
