What is a Mashup?
 A Mashup is a composite Web
Application built by end-users
through combining resources
available along the Internet
(Sheth et al., 2007) (Simmen et al., 2008)



Composition model that allows combine resources (applications/data/GUI) to

Reuse resources and even mashups for developing novel applications and
decreasing development costs
Sharing open resources and mashups
Abstraction model that allows end-users without advance programming skills
to develop composite applications

16. Mashups
Benefits for Network Management?
 Web Services interact with
applications
 Mashups interact with endusers
 Network Administrators would
support their daily activities
by themselves
 Network Administrators would
develop their own content
 Network Administrators would
create,
enhance,
and
customize their workspaces

17. Software Defined Networking
Context
 The Internet has continuously and rapidly evolved in the Network
Access Layer and the Application Layer
 The Internet has suffered a standstill in the evolution of both the
Transport Layer and the Internet Layer --> Internet ossification
 New proposals to deal with the Internet ossification: Software
Defined Networks and Network Virtualization

22. Mashups & SDN
Mashups for SDN Management?

Mashups are Web applications created
through the integration of different
resources (e.g., data, application logic, and
user interfaces) available on the Internet

Mashups allow end-users, without advanced
programming skills to create their own and
customized applications

Mashups encourage both cooperation and
reuse among end-users

A
novel
mashup-based
approach lets to deal with the
heterogeneity of Virtual SDN
and
allows
Network
Administrators to build up SDN
Management
composite
solutions

Approach formed by
•
•
The SDN Mashup concept

23. Mashups & SDN
Stakeholders
 Virtual Network Provider (VNP) operates Virtual SDN Resources
and provides them to Virtual Network Operators (VNO)
 A VNO provides Virtual SDN Slices to customers and/or
applications
 SDN Administrator (Network Administrator)
(Chowdhury and Boutaba, 2009) (Khan et al., 2012)
23 / 16
Oscar Mauricio Caicedo Rendón

24. Mashups & SDN
Concepts
 A Virtual SDN Slice is formed by one or more Virtual SDN containing
several Virtual SDN Resources.
 Virtual SDN Resources
• Virtual Network Elements (VNE) - e.g., Vyatta Router and Open vSwitch
running on a hypervisor
• NOS – e.g., NOX, POX, Beacon, and Floodlight
• Network Applications (NAP) - e.g., a network service to multicast path
selection running on NOS
24 / 16
Oscar Mauricio Caicedo Rendón

25. Mashups & SDN
What is a SDN Mashup?
• A SDN Mashup is a composite Web application, centered in the
Network Administrator, and aimed to manage any SDN that has been
deployed using Network Virtualization
25 / 16
Oscar Mauricio Caicedo Rendón

26. Mashups & SDN
SDN Mashup Characteristics
 It hides the heterogeneity and complexity of SDN Resources (NAP,
NOS, and VNE)
 It allows to combine information retrieved from SDN Resources
 It lets to blend local and external visualization APIs to generate
integrated and advanced GUIs
 It provides access to multiple Network Administrators to enable
communication and collaboration among them by sharing and reusing

35. Conclusions
 Mashup technology empowers the SDN Administrator with the
important ability to build, extend, and customize SDN management
solutions
 SDN Mashups have little compromise on usability, particularly during
the SDN Mashup composition process
 SDN Mashups leads the Mashup technology towards a new application
domain (SDN Management) and the Network Management towards an
environment centric in the Network Administrator
