EMULATING END-HOST MODE FORWARDING BEHAVIOR

摘要

Apparatuses, methods, program products, and systems for emulating end-host forwarding behavior is disclosed. A data module receives a data packet at an ingress port of a network switch. The data packet includes a source address and a destination address. The network switch includes ports designated as uplink ports and different ports designated as server ports. An update module creates an entry in the forwarding database based on the data packet. The entry for the data packet includes the source address and either an undefined server port and an undefined uplink port in response to the ingress port being an uplink port where an undefined port includes an identifier for a port that does not exist, or the ingress port and one of the one or more uplink ports in response to the ingress port being a server port. A transmission module forwards the packet to a destination address.

主权项

1. An apparatus comprising:
a data module that receives a data packet at an ingress port of a network switch, the data packet comprising a source address and a destination address, the network switch comprising one or more ports designated as uplink ports and one or more different ports designated as server ports; an update module that, in response to a forwarding database of the network switch not comprising an entry that corresponds to the source address, creates an entry in the forwarding database based on the data packet, an entry comprising at least an address, a server port, and an uplink port, wherein the entry for the data packet comprises the source address and one of:
an undefined server port and an undefined uplink port in response to the ingress port being an uplink port, an undefined port comprising an identifier for a port that does not exist; andthe ingress port and one of the one or more uplink ports in response to the ingress port being a server port; and a transmission module that forwards the data packet from the network switch to the destination address using one or more of a server port and an uplink port in response to checking the forwarding database for an entry that corresponds to the destination address.
