Highly scalable architecture for application network appliances
First Claim
1. A network device comprising:
- a switch fabric;
a first service module coupled to the switch fabric; and
a second service module coupled to the first service module over the switch fabric,wherein in response to packets of a network transaction received from a client device over a first network to access a server of a data center having a plurality of servers over a second network, the first service module is configured to;
perform a first portion of OSI (open system interconnection) compatible layers of network processes on the packets;
wherein the second service module is configured to perform a second portion of the OSI compatible layers of network processes on the packets andwherein the first portion includes at least one OSI compatible layer that is not included in the second portion.

Abstract
A highly scalable application network appliance is described herein. According to one embodiment, a network element includes a switch fabric, a first service module coupled to the switch fabric, and a second service module coupled to the first service module over the switch fabric. In response to packets of a network transaction received from a client over a first network to access a server of a data center having multiple servers over a second network, the first service module is configured to perform a first portion of OSI (open system interconnection) compatible layers of network processes on the packets while the second service module is configured to perform a second portion of the OSI compatible layers of network processes on the packets. The first portion includes at least one OSI compatible layer that is not included in the second portion. Other methods and apparatuses are also described.

18. A machine-readable storage medium having instructions stored therein, which when executed by a processor, cause the processor to:
-
receive packets of a network transaction at a network device from a client device over a first network for accessing a server of a data center having a plurality of servers over a second network; process at a first service module of the network device a first portion of OSI (open system interconnection) compatible layers of network processes on the packets; and process at a second service module of the network device a second portion of OSI compatible layers of network processes on the packets, wherein the first portion includes at least one layer that is not included in the second portion. - View Dependent Claims (19, 20, 21, 22, 23, 24)
