Philosophy behind TELCO Virtual Organization as a technological revolution

for Telecommunication

Efficient Billing system Efficient billing while roaming

Information sharing among mobile service providers Using Distributed Databases, Grid services and

clusters

Intelligent Service Discovery

5

Background of Mobile System (1)

6

• Billing System– The system that collects billing ticket generated from services

modules, translates and store them (in database system).– Basically including Mediator(collection, translation) and

Database system.

• Roaming– A service in Mobile system that enables mobile subscribers can

access and use services from other network provider.

• Bridging Services– Providing mechanism that allows mobile subscribers to

access services from other services providers from home network provider or visited network providers (using roaming)

Background of Mobile System (2)

Virtual Organization (VO)

VO is a temporary alliance of entities

• To share skills or core competencies and resources

• In order to better respond to business opportunities

• Whose cooperation is supported by computer networks

8

VO Challenges Technical

Capability of the communications network Hardware and software compatibility Computer security Dynamic nature of technology

Communication

Misinterpretation of messages Message ambiguity Reduction in the quality of the message delivered Delay in responding to a message

9

• Managerial

– Potential abuse and wasted time– Managing and controlling at a distance– Ensuring employee self-motivation and self-

discipline.– Defining goals and limits of responsibility– Loss of personal contact

VO Challenges…(2)

10

Best Practices for Overcoming Challenges Encourage cooperation, trust and empowerment.

Ensure skills and competencies are complementary and well define roles.

Ensure contractual agreements are clear and specific on roles and deliverables.

Occasional face-to-face interaction.

Provide training which is critical to team success.

Ensure that technology is compatible and reliable.

Provide technical assistance that is competent and available

11

VO Benefits in Telecommunication sector Efficient service management Efficient billing system Enterprise collaboration through sharing of

resources Reduce administrative costs No local IT infrastructure for each enterprise Create more efficient operations Companies can exchange their services in order to

provide more opportunities to each customer We can use cheap computers and cheap operating

systems or the existing ones

12

Conceptual VO Design

13

• Marketing and Planning Interface for advertisements, user

survey….• Operations and IT Support Interface that gives and checks

interconnection requirements and system for fault tolerance

• Financial and Accounting Interface for keeping payment agreement

and subsequent payment records between operators

• Security Standard Security functions as

authorization, privacy, integrity, authentication and non-repudiation

• Management Portal for taking feedbacks and

authorizing operators

Organizational Design

14

• Message Passing– Machines can exchange messages to each other.– Simple implementation of socket

• Client Server– An centralized organization with one server serving

multiple clients– Clients send request to server, server receives, does

action and send back relevant responses.• Peer to Peer

– Decentralized organization of autonomous entities.– Both side are server/client: having responsibility for

sending request and response

Traditional Distributed Paradigms…(1)

15

• RMI– A Java-based distributed technology that enables a object to

invoke methods from remote objects in different machine.– Using pre-defined java interface for consensus of interaction

between client and server– Communication is based on JVM-JVM

• CORBA– A standard defined by OMG that allows objects from different

languages in different platform can interact with each other– Using Interface Description Language for consensus of

interaction so that it can be implemented by multiple languages– ORB is the heart of CORBA which has responsibility for getting

request from client, invoking methods from server, and send back the result.

– IIOP is used for communication in CORBA

Traditional Distributed Paradigms…(2)

16

• Web Services– Basic distributed computing technology that

constructs client-server interactions using services provider/consumer mechanism

– Web Services are platform independent and language independent

Security Security policy

An updated document stating how the VO tends to implement security

Digital Signature Technology To maintain authentication, authorization and non-

repudiation

Transport Layer Security To ensure privacy and integrity

Network Security To protect from intrusion through any system on the

network

18

Grid…(1)

• Grid computing allows:

– Seamless resource sharing of distributed heterogeneous resources in a dynamic way

– Resources can be Computing, Storage or Online collaborative tools

19

Grid...(2)

• Enables the creation of a single IT infrastructure that can be shared by multiple business

• Types of Grid Systems– Computational Grid– Data Grid

20

Grid Motivation...(1)

• Businesses/Organizations have

– No more limitation on Computing power

– No difficulties in sharing data across distributed heterogeneous resources

– Predict Customer needs through large dataset analysis

– Enhanced Operational Resilience

21

Grid vs Traditional Distributed Approach

• Grid Enables– Optimise use of Distributed Shared

Resources

– Same semantics for every resource

– Coordinated Failover control

– Loosly Coupled Architecture

ORACLE & IBM

Enterprise Grids

24

Oracle Grid Approach• Oracle defines grid technology as

– “an enterprise's computational resources – servers, networks, storage, and information – acting together to create one or more large pools of computing resources”

• Implements a way to provide on demand computing resources

• Resource as “utility”

25

Oracle Strategy• Oracle provides tightly coupled

clustered architecture bundled in Oracle 11g Grid containing

– Oracle Applications i.e Enterprise Resource Planning or Customer Relationship Management

– Oracle Database

– Oracle Middleware

26

IBM Grid Approach

• IBM defines Grid as– “enables the virtualization of distributed

computing and data resources such as processing, network bandwidth and storage capacity to create a single system image, granting users and applications seamless access to vast IT capabilities”

– IBM views grid as Heterogeneous resources

27

IBM Strategy• IBM provides dynamic Service Oriented

Infrastructure to virtualize distributed resources

• IBM provides– Infrastructure software– Storage– Servers

• Tune or port 3rd party Application solutions to its grid infrastructure

28

Oracle VS IBM Dissimilarities

Oracle builds and sells application solutions

IBM does not.

Oracle runs on 3rd party vendor's Operating system

IBM builds its own operating system

Oracle does not sell grid hardware

IBM builds and sells hardware

29

Contd…

Oracle only provide data grid solution

IBM povide compute, data, Enterprise grid

Oracle grid is not build on GGF Standards

IBM is build on GGF Standards

Oracle grid is integration of Oracle with 3rd party vendors

IBM can also provide Turnkey solution

30

Technology Recommendation

• According to our requirements

– IBM is the more suitable choice. WHY?

• IBM unlike Oracle deals with distributed data grids

• IBM Unlike Oracle deals with Heterogeneity

• IBM Unlike Oracle can work with 3rd party hardware vendors and storage databases

Summary & Conclusion• Investigation on general points of VO (VO

meaning and organizational hierarchy, benefits, features, Supporting technologies, existing commercial VO’s and structures )

• Investigation on State-of-the-Art

• Successfully Designed Complete Virtual Organization for efficient distributed resource sharing in Mobile Infrastructure using grid Technology
