Method and system for optimizing a network by independently scaling control segments and data flow
First Claim
1. A network traffic management computing device, comprising:
- at least one of a processor coupled to memory and configured to implement hardware logic or execute programmed instructions stored in the memory to;
direct data packets received from a client requesting a resource, to the requested resource, when the data packets are associated with an existing connection to the requested resource;
request and receive requesting and receiving instructions for directing the data packets to the requested resource, when the data packets are not associated with an existing connection to the requested resource; and
categorize one or more of the data packets into one or more data flows based on a flow signature comprising service type; and
direct the data packets to at least one of a plurality of server computing devices hosting the requested resource based on the instructions and the flow signature comprising service type.

Abstract
A server array controller that includes a Data Flow Segment (DFS) and at least one Control Segment (CS). The DFS includes the hardware-optimized portion of the controller, while the CS includes the software-optimized portions. The DFS performs most of the repetitive chores including statistics gathering and per-packet policy enforcement (e.g. packet switching). The DFS also performs tasks such as that of a router, a switch, or a routing switch. The CS determines the translation to be performed on each flow of packets, and thus performs high-level control functions and per-flow policy enforcement. Network address translation (NAT) is performed by the combined operation of the CS and DFS. The CS and DFS may be incorporated into one or more separate blocks. The CS and DFS are independently scalable. Additionally, the functionality of either the DFS or the CS may be separately implemented in software and/or hardware.

7. A method for directing communications over a network, the method comprising:
-
directing, by a network traffic management computing device, a data packet, received from a client requesting a resource, to the requested resource, when the data packets are associated with an existing connection to the requested resource; requesting and receiving, by the network traffic management computing device, instructions for directing the data packets to the requested resource, and directing the data packets based on the instructions, when the data packets are not associated with an existing connection to the requested resource; categorizing, by the network traffic management computing device, one or more of the data packets into one or more data flows based on a flow signature comprising service type; and directing the data packets to at least one of a plurality of server computing devices hosting the requested resource based on the instructions and the flow signature comprising service type. - View Dependent Claims (8, 9, 10, 11, 12)

13. A non-transitory computer readable medium having stored thereon instructions for directing communications over a network comprising machine executable code which when executed by a processor, causes the processor to perform steps comprising:
-
receiving a request for instructions for directing a data packet received from a client requesting a resource, wherein the data packets are not associated with an existing connection to the requested resource; categorizing one or more of the data packets into one or more data flows based on a flow signature comprising service type; and directing the data packets to at least one of a plurality of server computing devices hosting the requested resource based on the instructions and the flow signature comprising service type. - View Dependent Claims (14, 15, 16, 17, 18)
