10 Copyright © 2013 DOCOMO Communications Laboratories Europe GmbH Network Research Group 10 Network Configuration Platform (NCP) Proof-of-Concept Service Request Service Description following Common Information Model / NDL "alias":"Video Streaming Service", "networkElements":[{ "id":1, "alias":"Video Server 1", "type":"/node/host/generic", "features":[{ ”attribute":”arch", ”value":"x86_64" },... Lightweight text-data interchange format (JSON,XML…) JSON -Prototype uses NDL based on FleRD (developed in collaboration with TU Berlin) -We need a standardized virtualization-aware Information Model / NDL

11 Copyright © 2013 DOCOMO Communications Laboratories Europe GmbH Network Research Group 11 Network Configuration Platform (NCP) Proof-of-Concept (II) Use Case: Geographically Distributed Video Streaming Service Physical Infrastructure Orchestration VN Mgmt. "alias":"Video Streaming Service", "networkElements":[{ "id":1, "alias":"Video Server 1", "type":"/node/host/generic", "features":[{ ”attribute":”arch", ”value":"x86_64" }, …. JSON REST API

12 Copyright © 2013 DOCOMO Communications Laboratories Europe GmbH Network Research Group 12 Network Configuration Platform (NCP) Proof-of-Concept (III) Service Provider GUI -Define end-to-end service -Get access information NCP Admin GUI -View physical topology -Check VNet mapping

13 Copyright © 2013 DOCOMO Communications Laboratories Europe GmbH Network Research Group 13 Summary –An architecture and its building blocks for orchestrating end-to-end services were proposed –A Proof-of-Concept of such an architecture was presented –Open research issues have been discussed Future Works –Standard based north- and southbound I/F design –Standard multi-layer, multi-vendor information model –Implement new resource allocation algorithm (see PIMRC’13 - Path Protection with Explicit Availability Constraints for Virtual Network Embedding) Conclusions

15 Copyright © 2013 DOCOMO Communications Laboratories Europe GmbH Network Research Group 15 Network Configuration Platform (NCP) Proof-of-Concept. REST API RESTful web API. CRUD (Create,Read,Update,Delete) operations Jersey 2.0 (Open Source implementation of JAX-RS) Some examples: –Create network: POST /NCP/api/v1/ /network Body: Network request in JSON or XML format –Get network information: GET /NCP/api/v1/ /network/ –Modify network: PUT /NCP/api/v1/ /network/ Body: Network request in JSON or XML format –Delete network: DELETE /NCP/api/v1/ /network/
