US 2002/0054591 A1 · FABRIC SYSTEM AND METHOD FOR ASSIGNING IDENTIFIER FOR FABRIC APPARATUS THEREFOR

Abstract

A fabric system connects a plurality of fabric groups into a plurality of stages between terminal nodes and performs exchange of variable length frame. The fabric has an assignment signal transmitting portion transmitting an assignment signal fixedly assigned an identifier per port connected to other fabrics, a configuration information transmitting portion transmitting a configuration information indicative of correspondence of identifiers of the fabrics connected to the ports, a retrieval information preparing portion preparing a retrieval information for determining a fabric of transfer destination of the received frame per port and a port number on the basis of the identifier of each fabric and the configuration information, and a transfer destination determining portion determining the transfer destination of the frame on the basis of the retrieval information.

Dependent claims

A fabric system connecting a plurality of fabric groups into a plurality of stages between terminal nodes and performing exchange of variable length frame, said fabric comprising:

assignment signal transmitting means for transmitting an assignment signal fixedly assigned an identifier per port connected to other fabrics;
identifier assigning means for receiving said assignment signal transmitted from other fabric and assigning identifier determining own identifier according to a predetermined rule on the basis of said assignment signal;
configuration information transmitting means transmitting a configuration information indicative of correspondence of identifiers of the fabrics connected to the ports;
retrieval information preparing means for preparing a retrieval information for determining a fabric of transfer destination of the received frame per port and a port number on the basis of the identifier of each fabric and said configuration information;
and
transfer destination determining means for determining the transfer destination of said frame on the basis of said retrieval information.

3 more elements

An identifier assignment method per each fabric in a fabric system connecting a plurality of fabric group into a plurality of stages between terminal nodes for exchanging variable length frame, comprising the steps of:

in said fabric,
transmitting an assignment signal assigning a fixed identifier per port connected to other fabrics;
receiving said assignment signal transmitted from other fabric and assigning identifier determining own identifier according to a predetermined rule on the basis of said assignment signal;
transmitting configuration information corresponding to identifier of the fabric connected to the port;
and
preparing a retrieval information for determining the fabric of transfer destination of the received frame per port and the port number on the basis of the identifier of each fabric and said configuration information.

3 more elements

A computer readable memory storing a computer program performing assignment of identifier per each fabric in a fabric system connecting a plurality of fabric group into a plurality of stages between terminal nodes for exchanging variable length frame, said computer program comprising the steps of:

in said fabric,
transmitting an assignment signal assigning a fixed identifier per port connected to other fabrics;
receiving said assignment signal transmitted from other fabric and assigning identifier determining own identifier according to a predetermined rule on the basis of said assignment signal;
transmitting configuration information corresponding to identifier of the fabric connected to the port;
and
preparing a retrieval information for determining the fabric of transfer destination of the received frame per port and the port number on the basis of the identifier of each fabric and said configuration information.
