I like these definitions, they seem to fit the model of transport and service plane. On Dec 14, 2009, at 7:47 AM, Jeroen van der Ham wrote:
Hello,
As agreed at the last OGF, Inder and I have worked on the definitions of Network, Topology and Domain.
- Topology: A connected graph of Network Elements The intended usage of this is to describe the thing that a network provider advertises to others as his network topology that is available for use. I assume that a topology could include a set of interconnected groups, where that topology is what is available to others from the set of groups. Can a topology be a set of ports that are potentially interconnected? This sounds like a description of transport plane.
- Domain: An unordered collection of Network Elements managed under the same shared policy umbrella. This describes who or what is responsible for the Network Elements.
This sounds like what NSI is calling a NS actor. In the case where a NS actor calls other NS actors we might need a pseudo domain concept for the group of NSAs providing resources.
- Network: no definition We had a discussion about the meaning of this term and in the end we had to conclude that is not possible to provide a workable definition for the term 'Network'. The term Network has become so widely used for so many diverse meanings that it is impossible to create a strict definition that everyone can agree on, while still expressing something useful.
I agree with this.
