3. DISCOVER, DISRUPT, DELIVER
OpenMANO addresses successfully network creation,
becoming a sound foundation for further automation
VNF AND NS DESCRIPTORS MAKE NETWORK DESIGN SIMPLE
EPA SUPPORT (NFVO & VIM)
PROPER VARIETY OF L2 CONNECTIVITIES
VNF ON-BOARDING DOES NOT REQUIRE FORMAL INTEGRATION
• Abstract models that hide complexity to
network engineer: just nodes and links
interconnecting them
• Allows to deploy for high performance
• Passthrough, SR-IOV, Virtio
• E-Line & E-LAN
• Descriptor-based (openly available)

• Low-end laptops/PCs
• Functional tests
• Low cost
OpenMANO minimizes entry barriers for VNF developers
LOCAL DEVELOPMENT
&TESTING
• Real servers and switches
• Performance tests (EPA
can be enforced)
• Cost-effective shared pool
SHARED POOL FOR
DEVELOPERS
• Production/pre-production
environment
• Real network scenarios
• Final service configuration
