#1. Field of the Invention

#The present invention generally relates to a packet processing system, and more specifically, to a system and method for processing packets.

#2. Description of Related Art

#FIG. 1 shows a block diagram of a packet processing system in accordance with an embodiment of the present invention;

#FIG. 2 shows a flow chart of the operations prior to executing the packet processing method of an embodiment of the present invention; and

#FIG. 3 illustrates an operation flow chart for packet processing method of an embodiment of the present invention.

#The following illustrative embodiments are provided to illustrate the disclosure of the present invention, these and other advantages and effects can be apparently understood by those in the art after reading the disclosure of this specification. The present invention can also be performed or applied by other different embodiments. The details of the specification may be on the basis of different points and applications, and numerous modifications and variations can be devised without departing from the spirit of the present invention.

#FIG. 1 is a block diagram illustrating modules within the packet processing system of the present invention and the relationship between these modules and other external devices. As shown in FIG. 1, a packet processing system 100 is responsible for the packet forwarding mechanism on a network packet forwarding device 10, which is, for example, a modem, a router, a bridge, a hub, an IP share machine or an access point. In one embodiment, the network packet forwarding device 10 is, but not limited to, the access point. The packet processing system 100 includes a packet receiving module 1000, a packet replication module 1002, a packet modification module 1003, and a packet transmission module 1004.

#The packet receiving module 1000 receives the packets sent by a packet transmitting terminal 11 via a telecommunications connection 13, wherein the telecommunications connection 13 is either a wired telecommunications connection or a wireless telecommunications connection such as microwave, far infra red rays and etc. for the packet receiving module 1000 to receive packets. These packets are multipoint transmission packets such as broadcast or multicast packets. The packet receiving module 1000 can also receive unicast packets. In the present embodiment, the packet receiving module 1000 receives multimedia streaming multicast packets.
