| Architecture: | The CADENUS Mediation
Component architecture envisions a partitioning of system
functionalities into 3 major blocks, termed
Access Mediator, Service Mediator and Resource Mediator. Each
mediator belongs to one of the business actors involved: the
access provider, service provider and network provider
respectively.
The figure below depicts the overall architecture, with the three mediator blocks, their main functionalities and interaction points. A first trial architecture has been implemented to provide VPN services for one network domain. |
|
 |
||
| Access Mediator (AM): | ||
|
Enables users to input their requests
into the system. |
||
| Service Mediator (SM): | ||
| Manages
services and the physical access to these services via the
appropriate underlying network, using the Resource Mediator(s). |
||
| Resource Mediator (RM ): | ||
| Provides an
abstract view of the QoS characteristics of a Premium IP network
to a Service Mediator. - Manages network resources - Belongs to a Network Provider (NP) - Is Network Independent - it is independent of the network technology or means of providing QoS (e.g. DiffServ, MPLS, over-provisioning). A Network Controller handles all network dependent related tasks. |
||
| Network Controller NC: | ||
|
Manages network resources at a network dependent level. |
||
| A first trial architecture
has been implemented to provide VPN services for one network
domain. Figure 1 shows a simplified architecture, with the some of the needed data repositories and selected technologies for this implementation. |
