摘要：A method of handling data packets in a series of network switches is disclosed.An incoming data packet is received at a data port of a first lower capacity switch of theseries of network switches and a stack tag is resolved from a header of the incoming data
packet. The incoming data packet is forwarded to a first higher capacity switch, on a firststacked connection operating at a first data rate, based on the stack tag. A destinationaddress of said incoming data packet is resolved by the first higher capacity switch andthe header of the incoming packet is modified. The incoming data packet is forwarded toa second higher capacity switch, on a second stacked connection operating at a seconddata rate, based on the resolved destination address, where the header of the incomingdata packet is modified and the incoming data packet is forwarded to a second lowercapacity switch on a third stacked connection operating at the first data rate. Lastly, anegress port of the second lower capacity switch is determined based on the stack tagand the incoming data packet is forwarded to the egress port. A network switchconfigured perform the above method of handling data packets is also disclosed.
