Abstract
An Infiniband switch can have an input port and a plurality of output ports. The switch can be configured to interrogate at least a header portion of a received packet to determine an output port for the packet and to forward the packet to an output buffer associated with the determined output port. The switch can also be configured to determine an output buffer ratio in dependence upon at least an inbound data rate characteristic of the input port and an outbound data rate characteristic of the determined output port. The output port can be configured to commence onward transmission of the packet once a proportion of the packet conforming to the output buffer ratio has been written into the output buffer.
