CPC H04L 49/111 (2022.05) [H04L 49/112 (2022.05); H04L 49/15 (2013.01)] | 15 Claims |
1. A network system, which is capable of scaling fabric size, comprising:
P upper switches, wherein each of the P upper switches comprises a plurality of upper ports, and a group of upper switches selected from the P upper switches comprises P1 upper switches;
Q lower switches, wherein each of the Q lower switches comprises a plurality of lower ports; and
a first mapping device comprising:
P1 upper adapter terminals coupled to a part of upper ports of the P1 upper switches; and
P1 lower adapter terminals coupled to lower ports of a part of the Q lower switches;
wherein an upper adapter terminal of the first mapping device comprises PTX1 transmission channels and PRX1 receiving channels, (PTX1/P1) transmission channels selected from the PTX1 transmission channels are linked to a lower adapter terminal of the P1 lower adapter terminals by the first mapping device, remaining transmission channels of the PTX1 transmission channels are partitioned into (P1-1) first transmission groups, and the (P1-1) first transmission groups are respectively linked to (P1-1) lower adapter terminals by the first mapping device;
wherein (PRX1/P1) receiving channels selected from the PRX1 receiving channels are linked to the lower adapter terminal of the P1 lower adapter terminals by the first mapping device, remaining receiving channels of the PRX1 receiving channels are partitioned into (P1-1) first receiving groups, the (P1-1) first receiving groups are respectively linked to the (P1-1) lower adapter terminals by the first mapping device; and
wherein P, P1, and Q are positive integers, PTX1 and PRX1 are multiples of P1, and P>=P1.
