Service-Oriented Architecture for Distributed Enterprise Portal for Maintaining Global Patch Consistency

This paper presents the design, implementation of an extensible, scalable, Web services ripple propagate routable base, transnational hierarchical global patch consistent model called THGPCM (transnational hierarchical global patch consistent model). Improving the OPDS (original patching data source) enabled network equipments, capable of updating patch parameter that existed in enterprise with specified OPDS partially dependency relationships. The paper also proposed a new scalable patching replica routing service algorithm, that dynamic reconfiguration distributed forwarding data path within enterprises hierarchical region enterprise portal. On the basis of the ubiquitous replica consistency framework, many active patch flows can be pushed by real time, periodic, reservation, and queuing with priority/degradation/preemption etc. Apply scenario can reduce the global patch service cost of transnational enterprise network equipments and minimum the turnaround time of patch service delay.

1. Introduction

There is no question that there has been a radical shift in the type of services carried over the Internet. Changes in technology and bandwidth availability have been leveraged by new Internet protocols to realize new services, all of which are implemented over the same core network. This is truly a widening of the functions available to a customer, as the simple data delivery mechanisms have been extended down the food-chain to offer virtual private networks, virtual LANs, and pseudo wires to carry transport circuits over the connectionless infrastructure of the Internet.¹
