Introduction

Virtual SDN

Virtual SDN = SDN aided by virtualization technologies

A Virtual SDN is a subset of the underlying physical network and, usually, can be formed by several SDN-enabled virtual resources

Goal: Sharing a network physical infrastructure among several virtual networks

Introduction

Hypothesis based on Mashups

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 • The SDN Mashup System

Mashups are Web applications created through the integration of different resources (e.g., data, application logic, and user interfaces) available on the Internet (Simmen et al., 2008)

Mashups allow end-users, without advanced programming skills, to create their own and customized applications (Cappiello et al., 2010)

Mashups encourage both cooperation and reuse among end-users (Yu, 2008)



SDN Mashups

What is a SDN Mashup?

Definition • 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 Features 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

Graphical User Interfaces

It provides access to multiple Network Administrators to enable communication and collaboration among them by sharing and reusing SDN Mashups

(Joines, Willenborg, and Hygh, 2002)



Case Study

Shortcomings They were not devised to be extended and

enhanced by Network Administrators

They can be solely improved by network programmers in a low-level abstraction

They were just tested in network slices handled by NOX that is an OpenFlow-based NOS implemented in the C++ language

They cannot manage a Virtual SDN that uses more than one type of NOS

Related Work OpenRoad facilitates the management of IP

addresses in OpenFlow-based networks and the monitoring information of switches on the datapath (Yap et al., 2009)

OMNI a solution aimed to monitoring

OpenFlow-based networks (Mattos et al., 2011)

NetOpen supports the creation of Network

Applications by combining networking primitives that are SOA services (Kim and Kim, 2011)

Qualitative Analysis



Case Study

SDN Mashups They can be built by Network Administrators because of using an end-user programming approach

(wiring and drag-and-drop mechanisms)

Network Administrators do not require advanced knowledge about the APIs of NAP, NOS, and VNE

Network Administrators do not require to concern about the data mapping among the APIs of NAP, NOS, and VNE

SDN Mashups promote the innovation in SDN management solutions

Qualitative Analysis


Conclusions & Future Work

A novel mashup-based approach formed by the SDN Mashup concept and the SDN Mashup System that allows to carry it out

The approach empowers the SDN Administrator with the important ability to build, extend, and customize SDN management systems

The approach provides an easy-to-use Mashup Development Environment with little compromise on usability, particularly during the SDN Mashup composition process

A quantitative evaluation of the Slice Monitoring Mashup • Good response time of SDN Mashups regardless of network topologies and Virtual SDN

Resources • The negligible growth of response time as the number of Virtual SDN Resources is increased

The approach leads the Mashups towards a new application domain (SDN Management) and the

Network Management towards an environment centric in the Network Administrator


Conclusions


Conclusions & Future Work

Extend the SDN Mashup System, adding new features to perform other management tasks and appending more powerful graphical user interfaces to automatically compose SDN Mashups

Evaluate the decrease on the carrying out time of SDN management tasks by using our mashup-based approach

The acceptance by Network Administrators of SDN Mashups as network management solutions
