1 Framework and requirements for cloud computing

• WT-411: Definition of interfaces between Cloud CO functional modules. It defines the interfaces
between the functional modules in the Cloud CO architectural framework, as well as the Cloud CO
northbound API. Network transport protocols, the data models, schemas or APIs that are signalled
across them will be defined as well. Existing open interface works, as described in standards and
open source work is being leveraged as much as possible.
• WT-412: Test Cases for Cloud CO Applications. This work defines test cases for Cloud CO
applications. Cloud CO scenarios are described in Cloud CO application notes. The Cloud CO
application notes will detail how a certain service is instantiated, maintained and consumed across
the Cloud CO architecture. The test cases will be consumed by the Open Broadband Labs, effectively
validating the Cloud CO application note.
• WT-413: SDN Management and Control Interfaces for CloudCO Network Functions. This work
primarily enables the migration from SNMP/MIB towards NETCONF/YANG interfaces and potentially
other protocols to exercise not only traditional FCAPS management functions but also fine grained
flow control across VNFs and physical network functions (PNFs) network service graphs. This is an
essential step towards software networking introduction, automation and orchestration of PNFs and
VNFs in a Cloud CO type of architecture. The development of this Working Text shall also shape the
thinking on the way Cloud CO interfaces, especially for VNFs, are modelled and the opportunity to
reuse/extend existing YANG work for that.
• WT-416: CloudCO Use Cases and Scenarios. This Working Text complements the CloudCO
architectural framework specified in TR-384 by describing existing broadband service scenarios
supported by the CloudCO architectural framework as well the use cases that can be established
using this CloudCO architectural framework.
