1. A switch device, comprising:
an input buffer to store received packets;
an input header queue coupled to the input buffer and to:
store headers of the received packets;
generate a request corresponding to a respective received packet toward an output port based on a header of the received packet, wherein the header is stored in the input header queue; and
send the request toward the output port via a request crossbar dedicated for transferring a request, wherein a crossbar is a structure for transferring a piece of information within the switch device;
an output buffer to:
store outgoing packets to be transmitted via a respective output port; and
generate credits for granting requests based on space available in the output buffer;
a credit crossbar dedicated for transferring the credits to the input header queue;
a grant crossbar dedicated for transferring a grant corresponding to a request associated with a packet to the input header queue; and
a data crossbar dedicated for transferring the packet from the input buffer to the output buffer in response to the request being granted.
