| Abstract: |
Our early writings on the subject of managing XML Services identified three architectures: the pipeline server, hub and spoke and a P2P hybrid we call 'managed P2P' (MP2P). In this report we look more closely at the MP2P option and investigate the process behind BT's choice of Flamenco Networks as their Service management platform.

| Backgrounder: |
The managed peer to peer approach combines characteristics from the previous two architectures but essentially it splits out the SOAP content from the management information, sending the SOAP content peer to peer and service management information to the management hub. It is best described as a service management network rather than a hub. The pipeline server is still required but now becomes a relatively lightweight proxy through which service calls are made. It can encrypt, sign and compress the messages before routing them direct to the target Service URL and gathers management data such as response times and metering information which it sends to the service manager when appropriate. Although SOAP is not being routed through a hub you can still have some of the store-and-forward capabilities because the local proxy can queue messages locally. And by virtue of its link to the management server, dynamic routing of endpoint can be implemented.
We examine the pros and cons of the three architecture types, discuss controlling the costs of collaboration, and examine the requirement and support for the asymmetric case. We then look in detail at the NSC case study and report on our interview with BT where we asked them about their acquisition criteria, that led them to the MP2P approach. |
