Node for grid type single mode fiber optic local area network using tunable filters
First Claim
1. Apparatus for processing data packets within a grid-based mesh network having a plurality of particular nodes at the intersections of rows and columns of data transmission links which link the nodes together, comprising:
- (a) controller means for determining if a particular incoming data packet has previously been re-transmitted through said particular node;
(b) blocking means within each node for blocking re-transmission of said particular incoming data packet if said controller means determines that said data packet has previously been re-transmitted through said particular node, and if not, retransmitting said particular data packet to neighboring nodes, said blocking means further including at least several tunable notch filters.

Abstract
Apparatus for processing data packets within a grid-based mesh network having a plurality of particular nodes at the intersections of rows and columns of data transmission links which link the nodes together, which apparatus can determine if a particular incoming data packet has previously been re-transmitted through a particular node or has a wavelength of a data packet currently being processed through the node and, a plurality of tunable filters for blocking a data packet from being re-transmitted if the packet has such a wavelength or was previously re-transmitted through the nodes.

3. Apparatus for processing data packets within a grid-based mesh network having a plurality of particular nodes at the intersections of rows and columns of data transmission links which link the nodes together, comprising:
-
(a) means for identifying the wavelength of an incoming data packet incoming into a particular node and stopping further processing of said incoming data packet through said node if another data packet having said wavelength is currently being processed within said particular node; (b) means for determining if a particular incoming data packet has previously been re-transmitted through said particular node; (c) blocking means for blocking re-transmission of said particular data packet if said data packet has previously been re-transmitted through said node, and if not, re-transmitting said particular data packet to neighboring nodes; and (d) wherein said blocking means includes tunable notch filter means. - View Dependent Claims (4)

5. Apparatus for processing data packets within a grid-based mesh network having a plurality of particular nodes positioned at intersections of rows and columns of data transmission links which link the nodes together, comprising:
-
(a) means for identifying the wavelength of an incoming data packet incoming into a particular node; (b) means for determining if a particular incoming data packet has previously been re-transmitted through said particular node; (c) blocking means for blocking further processing of said incoming data packet through said node if another data packet having said wavelength is currently being processed within said particular node and for blocking re-transmission of said particular data packet if said data packet has previously been re-transmitted through said node, and if not, re-transmitting said particular data packet to neighboring nodes; and (d) wherein said blocking means includes tunable notch filter means. - View Dependent Claims (6)
