The document discusses the integration of distributed high-performance zones (HPZs) into the Belwue network utilizing OpenFlow and BGP to enhance connectivity for higher education and research in Germany. It highlights projects aimed at creating resilient and high-speed interconnections, addressing security and traffic management while overcoming challenges like infrastructure replacement and deployment reluctance. A prototype implementation on a local testbed is detailed, demonstrating the feasibility and cost-effectiveness of such integrations.
Resilient integration of distributed high performance zones into the bel wue network
- 1. Resilient Integration of Distributed High-Performance Zones into the BelWue Network Using OpenFlow IEEE Communication Magazine, Volume 55, Issue: 4 Software Defined Networks By: Anuj Tyagi 1
- 2. Important Terms NEIF – Network Fuer Innovation Forchung HPZ – High performance zones BS – Border Switch BR – Border Router CR – Campus Router BSC – BS Controller 2
- 3. What is BelWue? ISP in Germany for higher education and research org in Germany Providing interconnection between universities and NEIF (Network for Innovation and Research) Connecting 45 institutes consists of 150 network locations Working on integration of high performance zones go interconnect universities using Openflow and BGP Trend of centralization to offer high computing services from single institute NEIF providing 100 Gb/s bandwidth but legacy campus network lacks infra 3
- 4. How ? Different projects… ESNET Goal is to provide high speed interconnection network Using multiple DMZs based high speed zone to interconnect deptt by SDN switches with special security policies different from campus network SciPass SciPass describes a security-enhanced science DMZ. It uses an intrusion detection system (IDS) to classify traffic as trusted and untrusted. Using Openflow switches as load balancers for IDS Trusted network can bypass the firewall rules Goal of this approach is to facilitate the utilization of 100 Gb/s inter-campus connectivity 4
- 5. Resilient SDN based HPZ Integration • The HPZs are connected to BSs that are interconnected through a flexible optical platform — the NeIF 5
- 6. Resilient SDN based HPz Integration… • The integration is achieved through the BSs, which are equipped with appropriate forwarding rules. BGP is used to make the HPZs reachable from the campus networks and the Internet. Resilience mechanisms ensure that traffic is rerouted via the BelWue core network if the NeIF fails. • There is no connection to the production environment and the Internet 6
- 7. BelWue and HPz interconnection Infra 7
- 8. Prototype Implementation Implemented first prototype for HPZ Integration on Mininet on Local Testbed BelWue and Campus networks are production environments so virtualize environments HPZ equipped with test racks contain access to NeiF, management VPN, switch HP ProCurve 5406 switch configured with Openflow 1.3 Access to this equipment via VPN to the management switch which has direct links to additional network interface of the equipment Advantage: • Management traffic does not influence the experiments in the testbed • Access to the components is possible even in case of an error or misconfiguration 8
- 9. Issues it resolving? Integration is simple, cost effective Resilient Traffic engineering Security Incrementally deployment Cost efficient SDN-WAN 9
- 10. What’s the difference from traditional network? Any HPZ is connected to the NeIF platform through an OpenFlow-capable BS, which is operated by SDN controllers at BelWue 10
- 11. What are challenges or limitations? ISPs are reluctant to deploy due to critical edge and backbone operations network device performs Replacement of infrastructure Require new functional design and skilled engineers for it Ensure seamless and incremental upgrade Performance testing before deployment 11
