Strand interest: S4, S3 Pre-structuring Model Topic of interest P16, P12, CSA
Proposer: Budapest University of Technology and Economics (BME), Budapest, Hungary
Scope of competence being offered: BME is active in three major areas of research and innovation activities relevant to 5GPPP. First, BME offers hands-on expertize in Software-Defined Networking (SDN) with a focus on virtualization, end-to-end service programmability, fast prototyping, open-source solutions and live demonstrations. Second, BME has a strong track record in core networking research, especially in network infrastructure resilience (IP-level, multi-domain, optical, etc.) and routing (IP Fast ReRoute, multi-domain, router virtualization, etc.). Third, BME conducts research in the socio-economic aspects of networking with an emphasis on multi-stakeholder cooperation and competition scenarios, incentive-compatible mechanisms, and how technology impacts society.Accordingly, we have identified three specific activities in P16 we would like to contribute to.

  1. End-to-end service orchestration based on virtualized resources across multiple domains/operators: extending the Network Function Forwarding Graph (NF-FG) construct to multiple domains, multi-domain chaining of Virtualized NFs (i.e., overlay routing), automatic resource negotiation and bidding among multiple operators.
  2. Resilience of virtualized infrastructure across multiple domains and operators: definition of operator roles, responsibilities and Service Level Agreements (SLA) in multi-domain and multi-provider service chaining.
  3. Economic aspects of multi-operator SDN: information sharing/hiding – both operator-to-operator (bigswitch vs. topology-enriched view) and operator-to-customer (responsibility in service definition), charging and revenue sharing (SLA-based, fair sharing, e.g., based on Shapley value).

Since a multi-domain/operator environment changes the playing field with regard to SLAs, we foresee that topic 2 could also be pursued in a research-oriented direction in P12. Furthermore, BME offers its competence in the socio-economic impact assessment of ICT (as demonstrated in leading the corresponding task in FP7 EARTH on energy efficiency) to be used at the 5GPPP level in CSA.
