Abstract: A sense of location is provided for distributed virtual switch components into the service provisioning scheme to reduce latency observed in conducting policy evaluations across a network in a hybrid cloud environment. A management application in a first virtual network subscribes to virtual network services provided by a second virtual network. A first message is sent to the second virtual network, the first message comprising information configured to start a virtual switch in the second virtual network that switches network traffic for one or more virtual machines in the second virtual network that are configured to extend services provided by the first virtual network into the second virtual network. A second message is sent to the second virtual network, the second message comprising information configured to start a virtual service node in the second virtual network that provides network traffic services for the one or more virtual machines.

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 describe.
