Aggregator

Offers slices (virtual network and compute resources)

Combines several resource sets into a coherent resource pool

Slicer


A slice of resources is selected in a subset of it…

..and abstracted away a bit…

Gap Analysis: NFV View

1. ETSI NFV Management Orchestration (MANO) Essentials


Gap Analysis: SDN View

ONF SDN mapped to ETSI NFV MANO

No notion of software resources, hence VNFs, but only steering view

Orchestration and lifecycle management are control apps

Multi-level virtualization and control


Gap Analysis: UNIFY View

UNIFYed ESTI MANO and ONF SDN

Orchestration and lifecycle management are control apps

Unified recurring control for NFV and SDN

Combined software and network abstraction


NFVO NFVO: Service Lifecycle

NFVO: Resource

Orchestration (aggregation &

resource abstraction)

VIM: VIM: Orchestration &

Optimization (virt resources)

VIM: Domain Specific







ETSI NFV View


Key Message(s) SDN: recurring control structure

NFVO: joint software and network orchestration

VIM: from domain specific to abstract



The UNIFY Concept

20

• NFV & SDN, as enablers

• Multi-level (recursive)

• Reference Points for NF-FG: • Sl-Or, • Cf-Or, • Or-Ca

Multi-Domain

NFV service over virtualized resources

vs. recurrent resource virtualization and

control

Sliced infrastructure resources sold to other providers / enterprises (compute, storage and networking)

NFV services sold to tenants, e.g., vEPC,.. (implemented over virtualized resources)

UNIFYed recurrent control interface


• Logically centralized resource orchestration

• Joint software & network • Virtualization

• Programming

• Multi-level / recursive architecture


UNIFY Architecture

Universal Node (applying BiS-BiS) Bridging gap between compute & networking

• UN hosts VNFs as full VMs, lightweight containers or enhanced logical switch instances.

• Achieve high performance (e.g. by Intel® DPDK) in UN Virtual Switching Engine & optionally in various VNFs.

• VNFs of incoming NF-FG are mapped to internal network & to traffic steering between VNFs.

Physical networking, virtual networking (vSwitch) & VNF (compute) in same node

UNIFY’s Key Messages ~Equivalent set of functionality, abstraction etc… but different functional separation of concerns (ref NFV)

Recurring joint virtualization and control over compute and

network resources
