Networks Beng Chin Ooi

Corporate Network Applications

• National/regional/global Supply-Chain-Management and Product Tracking

• National Health Care…• Purpose: mainly for information

sharing/pulling

Requirements for Becoming a Disruptive Technology to Corporate Networks

• Enterprise Quality Data Processing– Secure– Efficient– Accurate– Must appear as if it is a centralized ERP or DBMS

• Scalability, Adaptability, Maintainability• Synchronization (map out from individual

server to respective peer node), but no ACID enforcement

Query form interface

Conventional Data Sharing (eg. SCM between companies)

Data engine

Supplier ERP

Database

Trader ERP

Manufacturer ERP

Traders

Wholesalers

Transporters

Retailers

Problems:

Expensive (huge initial investment on S/W and H/W)

Expensive Maintenance

Scalability

Update

Research Issues• Structured P2P Overlay Protocols

– Range based indexing/routing• Garbage collection is expensive

– Load Balancing• Indexing

– Just-in-time indexing– Partial indexing based on range/summary/histograms– Indexing many attributes?

• Query Processing– SQL queries (to what extent of complexity?)

• Status– Implementation of 2nd version ongoing

Features

•Peers are stable in corporate Networks

•Data mapping is easier (with some manual wrapping)

•Simpler queries
