Key issue #1:
how to describe such networks?
Semantic web
“a universal medium for the exchange of data where data
can be shared and processed by automated tools as well
as by people”
The Resource Description Framework (RDF) uses XML as
an interchange syntax.
Data is described by triplets:
Subject
Predicate
Object
NDL - Network Description Language
A way to describe network resources using RDF.
Parser can use the data to:
- generate network maps
- provide information to schedulers
<ndl:Device rdf:about="#Vangogh3">
<ndl:name>Vangogh3</ndl:name>
<rb:isOfType>ComputingElement</rb:isOfType>
<ndl:locatedAt rdf:resource="#Lighthouse"/>
<ndl:hasInterface rdf:resource="#Vangogh3:eth2"/>

Key issue #2:
How to book resources on such
networks?
Web services
Web services interfaces provide the API for the
reservation framework:
<wsdl:operation name="getResourceInformation">
<wsdl:operation name="getResourceList">
<wsdl:operation name="getTypeList">
<wsdl:operation name="getResourcesOfType">
<wsdl:operation name="reservePath">
<wsdl:operation name="getPossiblePaths">

> this schematic shows
• several input fibres and one output fibre
• light is focused and diffracted such that each
channel lands on a different MEMS mirror
• the MEMS mirror is electronically controlled to tilt the
reflecting surface
• the angle of tilt directs the light to the correct port
> in this example:
• channel 1 is coming in on port 1 (shown in red)
• when it hits the MEMS mirror the mirror is tilted to
direct this channel from port 1 to the common
• only port 1 satisfies this angle, therefore all other
ports are blocked

StarPlane Goals
Goals in the proposed StarPlane project:
1. fast, application-specific allocation of the
network resources with deterministic
characteristics;
2. application-specific composition of the protocol
stack that is used to control the resources;
3. low-level resource partitioning (and, hence, no
interference);
4. high-level requests (whereby policies and
inference are used to assist the user)..
