    Abstract: A method is provided in one embodiment and includes receiving at a network element a flow offload decision for a first service node that includes a portion of a service chain for processing a flow; recording the flow offload decision against the first service node at the network element; and propagating the flow offload decision backward on a service path to which the flow belongs if the first service node is hosted at the network element. Embodiments may also include propagating the flow offload decision backward on a service path to which the flow belongs if the flow offload decision is a propagated flow offload decision and the network element hosts a second service node that immediately precedes the service node on behalf of which the propagated flow offload decision was received and a flow offload decision has already been received by the network element from the second service node.

    Abstract: At a physical device in a network configured to host a virtual switch and one or more virtual machines, a packet is received at the virtual switch from a source virtual machine that is directly attached to that virtual switch. A destination Media Access Control (MAC) address is identified from the packet indicating a destination virtual machine for the packet. In response to determining that the destination MAC address of the packet is not present in a database of MAC addresses accessible by the virtual switch, the destination MAC address of the packet is replaced with a shared MAC address associated with a plurality of physical switches in the network.

    Abstract: A method is provided in one example embodiment and includes establishing a virtual trunk link between a first network element and a second network element. The first and second network elements are located at a first site and the first site and a second site comprise at least a portion of an overlay network. The method further includes receiving data traffic at the first network element, which data traffic is associated with a segment of the overlay network, and mapping a first network identifier allocated to the overlay network segment at the first network element to a virtual trunk link and a VLAN ID. The method additionally includes forwarding the data traffic from the first network element to the second network element via the virtual trunk link with the VLAN ID.

    Abstract: An apparatus and related method are provided for improving the performance of virtual desktop services. A network device is deployed in a network to intercept packets of a control session initiated by a client with a connection broker to obtain data from a host. The network device initiates a new control session to the connection broker on behalf of the client. The network device receives host information from the connection broker, replaces address information of the network device for the host information in a control session message and sends the control session message to the client. The network device establishes a data session with the client, initiates a data session with the host on behalf of the client and relays data between the data session with the host and the data session with the client such that the network device is transparent to the client and the host.
