Abstract
A method for preventing out-of-ordering of frames in a network switch, wherein the method includes the steps of receiving a first portion of a string of packets from a source port on a first port, transferring the first portion of the string of packets to a second port for transmission to a destination, and sending an indicator from the first port to the second port. The method further includes the steps of receiving the indicator at the second port, sending a response indicator from the second port to the first port, and receiving a second portion of the string of packets from the source port on a third port. Additionally, a method for preventing out-of-ordering of frames in network switch, wherein the method includes receiving packets on a first ingress port from a source port, transmitting the packets from the first ingress port to an egress port for transmission to a destination, and determining to switch the receiving of the packets to a second ingress port. The method further includes the steps of sending a switch indicator from the first ingress port to the egress port, determining when to send a response switch indicator from the egress port to the first ingress port, sendi…
