NETWROK APPARATUS AND METHOD FOR TRANSFERING PACKETS
First Claim
1. A network apparatus cluster for transferring a plurality of packets of a communication session to a network node, said network apparatus cluster comprising:
- a primary unit operable for receiving said packets comprising a first packet and a plurality of subsequent packets, for generating a session data set indicating said communication session and a balance data set based on said first packet, and for determining that said subsequent packets belong to said communication session according to said session data set; and
a subordinate unit coupled to said primary unit,wherein said balance data set indicates whether said first packet is distributed to said primary unit or said subordinate unit, and wherein said subsequent packets are transferred from said primary unit to said network node according to said balance data set.

Abstract
A network apparatus cluster for transferring multiple packets of a communication session to a network node includes a primary unit and a subordinate unit coupled together. The primary unit is operable for receiving the packets comprising a first packet and multiple subsequent packets, for generating a session data set indicating the communication session and a balance data set based on the first packet, and for determining that the subsequent packets belong to the communication session according to the session data set. The balance data set indicates whether the first packet is distributed to the primary unit or the subordinate unit. The subsequent packets are transferred from the primary unit to the network node according to the balance data set.

11. A method for transferring a plurality of packets of a communication session to a network node, said method comprising:
-
receiving said packets comprising a first packet and a plurality of subsequent packets by a primary unit; generating a session data set and a balance data set based on said first packet by said primary unit, wherein said session data set indicates said communication session, and said balance data set indicates whether to distribute said first packet to said primary unit or a subordinate unit; determining that said subsequent packets belong to said communication session according to said session data set by said primary unit; and transferring said subsequent packets from said primary unit to said network node according to said balance data set. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A network apparatus comprising:
-
a session module operable for transferring a plurality of packets of a communication session, wherein said packets comprise a first packet and a second packet; a firewall module coupled to said session module and operable for generating a session data set indicating said communication session based on said first packet; and a load balance module coupled to said firewall module and to said session module and operable for generating a balance data set indicating load balancing of said communication session based on said first packet, wherein said session module determines that said second packet belongs to said communication session according to said session data set and transfers said second packet according to said balance data set. - View Dependent Claims (22, 23, 24)
