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:
ObjectSubject Predicate
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"/></ndl:Device>

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"> <wsdl:operation name="isPathAvailable"> <wsdl:operation name="confirmPathReservation"> <wsdl:operation name="cancelPathReservation">

• Add WSSes at Amsterdam sites
• Is NOT supported in March 2006
• Full reconfigurability achieved
• Only limits are– Presence of card – Wavelength
blocking
• No changes to basic ‘static’ mesh
“branch” instead of “spur”
Adding WSSes increases reconfigurability

• Wavelength assignment remains – no external changes
• Adding WSSes allows redirecting wavelengths from/to VU and AMS

• Compared to day 1 now four instead of one possible redirection
• Redirection only limited by presence of cards and internal wavelength blocking

Day 2 – increased reconfigurability - adding cards
• Adding two cards allows to create more connectivity between ALL sites!
• Some sites can connectivity threefold (from 10 Gb/s to 30 Gb/s)

Module Operation
> 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)..
