Understanding Network Cloud Types and WAN Routing Protocols

This presentation provides an overview of different network cloud types, including public, private, and hybrid clouds, highlighting their respective applications and characteristics. It explains how routing is accomplished through a Wide Area Network (WAN), focusing on methods like destination-based routing and policy-based routing, particularly in the context of unified communications and Multiprotocol Label Switching (MPLS). The presentation also touches upon the Application Aware Routing SD WAN approach. The content references several research papers and patents to support its explanations.

QUESTION 1

Different types of network
clouds
 The cloud computing has different
network clouds which are public,
private and the hybrid clouds which
depends on the data you are working
with.
PUBLIC CLOUD:
They are for the internet where the service
providers use the internet to handle the
resources like applications of SaaS and
storage which is available to the public
(Guo et al., 2015, 20-24) .

Private
Clouds
 They are important for
handling the data
center architecture
(Brendel et al., 2015,
197-200). The setup is
based on providing
the flexibility,
scalability,
automation and the
monitoring in effective
manner.

Hybrid
Clouds
 They are for the
companies to control
the internal
management of the
private clouds (Spiers,
2015, 30-40). They
rely mainly on the
public cloud where the
instances are for
individual applications
that can be migrated
to the pubic cloud
systems.

How is routing through a
WAN accomplished?
 The routing is done through carrying the traffic
for the unified communications. There WAN
routing protocols can handle the voice traffic
through Multiprotocol Label Switching (Addis et
al., 2015, 171-177). The methods for routing
are:
a. Destination Based routing
b. Policy based routing

Methods of routing
The Application Aware Routing
SD WAN Approach Routing
