Introduction

Network Management Situations
 In the network management domain, many tasks require manual intervention by
Network Administrators

 Mainly, to manage unexpected and dynamic Situations that need rapid delivery of
good-enough and comprehensive solutions
 A Situation is a collection of entities (i.e., things in a domain), their attributes, and
relations in a time interval
 We call a sudden and dynamic network management situation as NMSit

(Zhao et al., 2011) (Jakobson et all., 2005)

Introduction

Network Management Situations
Options

NMSit
Finding the root of a
packet transmission failure
in a virtual network
composed of OpenFlow
slices handled by different
Controllers

Drawbacks

Collecting,
correlating,
and
visualizing network management
information by using proprietary
command lines, distinct Web
interfaces and/or external tools to
display information about packet
traffic

The
use
of
several
mismatched
solutions
consumes more time than
use an integrated solution

Developing low-level scripts to
integrate
the
proprietary
commands, Web interfaces, and
external tools

Developing home-brewed
scripts takes a lot of time
because
network
administrators usually do
not
have
advance
knowledge in programming

/ 16

Introduction

Problem Statement
The complexity and heterogeneity to collect,
correlate, and fuse information from multiple
resources (Web/Network Management)

NMSits

The demand of functionalities that allow
Network Administrators to rapidly create
tunnable situational solutions for NMSits

How to rapidly
deal with the
NMSits by focusing
on Network
Administrators

The need of visualization functionalities that
enable Network Administrators to get the
information
of
NMSits
in
a
very
understandable way

/ 16

What is Situation
Management?

Situation Management (SM) is an approach
to provide solutions that enable to analyze,
correlate, and coordinate the interaction
among people, information technologies, and
actions intended to overcome Situations

Investigative Aspect supports the
collection, correlation, and fusion of
information from entities in a specific
domain



Control Aspect
Situations

helps

to

solve

Mashups
What are Mashups?




A Mashup is a composite Web
application built by end-users through
combining resources available along the
Internet
If a mashup is developed for rapidly
coping with an immediate need of one
or a set of end-users, it can be
considered as a situational solution



Mashups support the daily activities
of end-users



Mashups allow end-users
develop their own content



Mashups allow to create, enhance,
and customize the workspace of
their end-users

Mashment Ecosystem

Hypothesis
Mashups

Abstraction Model
Composition Model
Focus on end-users
Investigative Aspect
Control Aspect

NMSits can be addressed by a
Mashment Ecosystem

Network
Administrators
participating in the Mashment
Ecosystem can deal with
NMSits faster than the ones
out of it.


/ 16

Mashment Ecosystem

What is a Mashment?
A Mashment is a tunable situational mashup that allows Network Administrators (their
end-users) to tackle NMSits by combining diverse types of resources from multiple
providers
 It hides the heterogeneity, complexity, and stiffness of resources used to address
NMSits
 It supports the easy collection, correlation, and fusion of information about NMSits
 It presents the information of NMSits in a visual and clear way
 It may be created rapidly by Network Administrators to cope with NMSits
 It is adaptable and easily customizable

Mashment Ecosystem

Resources
A resource is an entity conceived or that can be adapted to deal with one or more NMSits

 Network Management Resources. e.g. Ganglia, Citrix Center, NetOpen, and Monitoring APIs
 Web-based Management Resources. e.g. Google Maps API, MRTG, and RRDTool
 Operator Resources. e.g. Split, Merge, Aggregate, Invoke, Trigger, Receive, and Configure

11 / 16

Mashment Ecosystem

Stakeholders



Web-based Management Resource Providers. e.g. Google, Oetieker&Partners
Inc, and Yahoo


A stakeholder affects and
is affected by the
activities
and
interactions performed
by other one

Network Management Resource Providers. e.g. Citrix Systems and Cysco
Systems

Software Entity Providers are responsible for offering the software that
supports the functioning of the Mashment Ecosystem



Resource Creators are in charge of releasing (adapting) the resources to be used
for coping with NMSits. e.g. The Open Software community and independent
professional developers



Mashup Creators create, publish, share, sell, and buy Mashments. e.g. Software
companies, professional developers, and end-users



Network Administrators deal wih NMSits by launching Mashments in the
proposed Ecoystem

Mashment Ecosystem

Activities
An activity is an action conducted by one or more of stakeholders in the software entities
 Releasing --> Resource Creators

Creating
Reusing
Publishing

and
Mashup Creators

13 / 16

Mashment Ecosystem
Interactions
An interaction takes place in the relationships stakeholder/stakeholder and software
entities/software entities
 Occur and Tackling represent the emerging of NMSits and the corresponding responses
offered by the Mashments respectively
 Provide and Consume represent the supplying and consumption of resources --> Resource
Providers, Resource Creators, Mashup Creators, and Network Administrators
 Instantiate represents the request to execute a Mashment--> Maker and Engine
 Announce represents the publishing of Mashments to be commercialized --> Maker and
Marketplace
 Commercialize represents the sharing, purchasing, and selling --> Mashup Creators and

Mashment Ecosystem

Software Entities
The software entities are responsible for supporting and automating the activities and
interactions happening in the Mashment Ecosystem
 Mashment Maker allows to create, reuse, launch, and publish Mashments
 Mashment Engine creates instances and control the lifecycle of Mashments
 Mashment Marketplace allows to stablish a new value chain in which revenues are
shared not only by providers but by all stakeholders
•

In the Mashment Store are performed selling, sharing, and buying

•

In the Mashment Repository are stored the Mashments to be sold, shared, and
purchased

management situations faster than using current approaches/solutions

 Using KLM and Experimental Evaluation: the Mashment Ecosystem empowers Network
Administrators with the important ability to rapidly create, launch, and publish
Mashments
