Network for supporting advance features on legacy components
First Claim
1. A network device for processing packets, the network device comprising:
- at least one legacy component for performing basic processing on packets in the network device; and
at least one advanced component for performing advanced processing, that can not be performed by the legacy component, on packets in the network device, wherein when an incoming packet to the legacy component requires advanced processing, the legacy component performs the basic processing and transmits the packet to a loop-back port on advanced component, and wherein upon receiving the packet, basic processing is disabled on the advanced component and advanced processing is performed on the packet prior to transmitting the packet to an egress port.

Abstract
A network device that processes packets and includes at least one legacy component for performing basic processing on packets in the network device. The network device further includes at least one advanced component for performing advanced processing, which can not be performed by the legacy component, on packets in the network device. When an incoming packet to the legacy component requires advanced processing, the legacy component performs the basic processing and transmits the packet to a loop-back port on advanced component. Upon receiving the packet, basic processing is disabled on the advanced component and advanced processing is performed on the packet.

19. A method for processing packets, the method comprising the steps of:
-
receiving an incoming packet on one of a one legacy component or an advanced component;
performing basic processing on packets by a receiving component;
transmitting, by the receiving component, the packet requiring advanced processing to a loop-back port on the advanced component, if the receiving component is a legacy component; and
disabling basic processing, by the advanced component and performing advanced processing on the packet.

20. A apparatus for processing packets, the apparatus comprising:
-
receiving means for receiving an incoming packet on one of a one legacy component or an advanced component;
performing means for performing basic processing on packets by a receiving component;
transmitting means for transmitting, by the receiving component, the packet requiring advanced processing to a loop-back port on the advanced component, if the receiving component is a legacy component; and
disabling mean for disabling basic processing, by the advanced component and performing advanced processing on the packet.
