Peer-2-Peer Network with a Distributed Sitite Space.



-=- A Spherical Double-Spiral. -=-

Can be used in forming Distributed Objects in 3D,
including Distributed Stitie Space in 3D, or Distributed Hash Table in 3D,

... it has a communication cycle & fairly efficiently uses 3D Space,
... without forcing client object to reach inside, past the outer layer.
a client object can, for example scan,
(using directional/cone multicast wireless communication for example)
for 108 closest data structure objects, with load report,
then can choose either at random or by workload an object to communicate with.

Introduction.

One can look at Stitie Space as on a data structure that manages objects storing & communication in 3D-addressed space.

Most of ideas in this article requires a version 1.2 of Stitie Space, or later, however.


In-space objects communication.

Objects within can communicate with each other without accessing Stitie Space if they have coordinates & can find path - with or without using the 'long-range links'.

This fits well with peer-2-peer communication model.


Distributed Stitie Space.

When target object's coordinates are not available, Stitie Space can be contacted for these. Client object can request for other information & services as well, but these are more expensive than independent communication & performance.

Many requests to Stitie Space in short time-frame can cause a system overload, delays in communication or crashes. But Stitie Space can be replicated & distributed in similar way as the Distributed Hash Table.

In this case response or a service might not be immediate, because of data synchronization with other Stitie Space instances, and because of not locking resources & services for other client objects - a client object sends request to one of Stitie Spaces, then waits for response - perhaps on a concurrent thread as well. When a Distributed Stitie Space is synchronized (with other Stitie Space instances) & has available time for that, it just sends to a client object information it needs, or performs a service. Security Certificates & Privileges are considered as well.


Stitie Space Services might include:
- Communication between objects - for example when objects move often & when their coordinates change with time - when there are no proper long-range communication links,
- Handling requests to reform Space with MATEN or Prism functionalities,
- Establishing long-range communication links between client objects,
- Reserving destination Coordinates & Empty Movement Paths before a client object movement in space - for a given amount of time, at least.
- Updating coordinates registry in space after reaching destination by a client object.
