4. Key
requirements
① Faster deployment and
adjustment
Rapidly deploy or adjust services
based on requirements
② Easier management
The workplace is migrated frequently,
but the network configuration
remain unchanged.
③ Lower cost
Lower price, security tunnel, but do
not need exclusive physical tunnel.
Target Customers and Key Requirements of SD-WAN
SME and start-up companies
They have small scale, high cost
pressure. Most of them are
technically innovative companies
and gather in commercial
buildings or entrepreneurial base.
They need cheap cloud resource
and fast internet.
Chain enterprises
They have a large number of
branches with wide distribution,
and have a lot of tunnels under
HQ. Overlay network is used for
most of ordinary services , which
reduces the cost of enterprise
and realizes the layer 2
management
Enterprises cross carriers
An enterprise leases multi-
carriers’ network, overlay
network can shield the underlay
network and solve network
internection problem

5. Product Form of SD-WAN
Product form
1. A terminal device placed on the user premise, while providing VPN
capability;
2. In B2C scenario, each CPE is obtained from carriers and connect to
carriers’ network directly;
3. In B2B2C scenario, each CPE is obtained from building property or
carriers and connect carriers’ network through aggregation
equipment of building.

Users select VNF at portal. The image doesn’t need to be downloaded if it’s
stored locally. On the contrary, the image should be downloaded if it’s stored
on the server.
2 VIM sends commands to hypervisor to allocate VM for VNF, VM starts up and
downloads OS(such centos) and VNF image from image server.
3 VNF sends DHCP request to DHCP server in CO and gets IP and management IP,
then VNF can be online.
4 SDN controller sends commands to uCPE and lets user service flow pass
through VNF, and forwards service flow through service tunnel .

2 VNFM deploys VNF to reference cloud resource in various network conditions
to ensure that VNF works normally and establishes a performance baseline;
3 At the same time, resource verification tool verifies if target NFVI is ready for
VNF deployment.
4 When the target NFVI is ready for VNF deployment, the VNFM deploys the
VNF to target NFVI and executes VNF testing to validate that the VNF is
running with expected performance in the target NFVI.
