Description

This Building Block Type belongs to Working Area Network (NW). Distribution is a facility that offers data transport between two or more (logical and/or physical) data transport segments. This is accomplished by performing one or more of the following actions on data packets:

Routing and forwarding;
Address translation (manipulation of the source or destination address that's located in the packet headers);
Media translation (changing the encapsulation type of data packets).

Optionally, forwarding decisions can be based not only on address information, but also on filtering criteria. However, for practical reasons this functionality is described in and assigned to the Building Block Type Traffic Filtering.

Examples of devices that perform Distribution functions are:

Multilayer switches
Routers
SAN Directors.

Distributie is een voorziening die datatransport tussen twee of meer (logische en/of fysieke) datatransportsegmenten levert. Dit komt tot stand door een of meer van de volgende bewerkingen op de datapakketten uit te voeren:

routeren en doorsturen;
adres vertalen (manipulatie van het bron- of doeladres in de pakket-metainformatie);
mediavertaling (verandering van het encapsulatie type van datapakketten).

Optioneel kan de beslissing om door te sturen niet alleen op adresinformatie gebaseerd worden, maar ook op andere filtercriteria. Om praktische redenen wordt deze functionaliteit beschreven in en toegewezen aan het bouwblok type Traffic Filter.
