Network Softwarization
1 like348 views
The document discusses the principles and applications of Software-Defined Networking (SDN) and Network Functions Virtualization (NFV), presented by Dr. Ahmad Tajuddin bin Samsudin at a conference. It outlines the benefits of separating network control from data forwarding, minimizing hardware dependency, and improving service delivery through automation and flexibility. Additionally, it highlights the existing challenges within the current vendor-centric network systems and the need for a transformation in the telecommunications industry to overcome operational inefficiencies.

- 3. TM Research & Development 3 SDN concept The physical separation of the network control plane from the forwarding plane, and where a control plane controls several devices. Thus enabling the network control to become directly programmable and the underlying infrastructure to be abstracted for applications and network services. SDN Application: path computation, resource pool, self healing, DDOS protection,fault prediction, network optimization, etc SDN Controller: to program, orchestrate, control and manage the network resources through software Network functions perform the transport and the processing of data packets according to the decisions made by the SDN control layer Data plane shall be able to used existing network technology such as routing (e.g. OSPF.BGP), MPLS, ACL, QoS, L2VPN, L3VPN, IP transport, Ethernet transport, etc

- 9. TM Research & Development Current Network Consists of dedicated equipment with high- functionality for each necessary function.
- 10. TM Research & Development Silo-like development Vendor lock-in Initiative of functional enhancement is taken by vendors. Even small function addition can affect whole network system. Oligopolists Resource Inefficiency Unable to share unused resources between functions, locations, hardware units, and so on ... Silos are great for developing technology but destructive to service provider.
- 11. TM Research & Development Gap between the Service Providers and Vendors SDN & NFV is now attracting the industry to change the development style of carrier networks but there still is a large gap between the service providers and the vendors. ● Vendor silo ● Dedicated high- end routers SDN NFV ● Multi-vendor ● Virtualization ● Simplify Network Operations ● Commercial off-the- shelf ● High CAPEX/OPEX ● Resource inefficiency ● Long Time-to-Market ● Vendor lock-in ● Drastic cost reduction ● Quick Time to Market ● SP initiative in function enhancement, optimization Expectation Large margin by selling high-end routersV SP ● Reduction of margin ● Commoditization makes differentiation difficult ● Want to keep initiative by tight- coupled product Concern GAP
