In an example embodiment, there is disclosed an apparatus comprising a first interface configured to receive a packet from a client, a second interface configured to transmit the packet to a server, a third interface configured to communicate with at least one processing device, redirection module in communication with the first interface, the second interface and the third interface, and flow monitoring and state information module in communication with the first interface, the second interface, the third interface and the redirection module. Responsive to receipt of the packet on the first interface, the redirection module is operable to communicate with the flow monitoring and state information module whether state information exists for the packet, the state information comprising an address for a processing device. The redirection module is operable to route the packet to the processing device responsive to determining state information exists for the packet.

In one embodiment, a method for tracing a connection path from a source node to a destination node through a network having one or more transparent proxies includes generating a trace packet at the source node, transmitting the trace packet over the network towards the destination node, and receiving trace response packets in response to transmission of the trace packet. The trace response packets include a packet from the destination node and a packet from each of the transparent proxies in a data path from the source node to the destination node. Each of the packets from the transparent proxies includes an identifier of the transparent proxy transmitting the packet. The method further includes identifying the transparent proxies in the connection path based on information in the trace response packets. An apparatus for tracing a connection path is also disclosed.

In order for intermediary WAAS devices to process and accelerate ICA traffic, they must decrypt the ICA traffic in order to examine it. Disclosed is a mechanism by which the ICA traffic may be re-encrypted for transport over the WAN in a manner that does not require explicit configuration by the administrator of the WAAS devices.

A method is provided in one example embodiment and includes identifying a first data center configured to receive a request initiated by an end user. The method also includes detecting a presence of a wide area application service (WAAS) and identifying a second data center. The method further includes signaling, in response to the presence of the WAAS, to redirect data packets associated with the request to the second data center. In more specific embodiments, the signaling includes adding a TCP option to packets of a session associated with the end user to inform components of redirecting capabilities of a WAAS element. The detecting can include recognizing a transmission control protocol (TCP) option in detecting the presence of the WAAS. The TCP option can be used to identify capabilities of a WAAS element that is involved in servicing the request of the end user.

In one embodiment a method includes detecting, at a first Wide Area Network (WAN) device deployed at an edge of a WAN, a packet passing through the first WAN device and departing a node with which the first WAN device is associated for another node connected to the WAN, identifying, by the first WAN device, a network destination address to which the packet is addressed, obtaining from memory accessible to the first WAN device an identifier of another WAN device associated with the network destination address, and marking the packet with the identifier to generate a marked packet. The marked packet is then received by a WAN device, which detects the identifier, and passes the marked packet to the identified WAN device. In an embodiment, the WAN device associated with the network destination address is a WAN device that first detects a synchronization-acknowledgement (SYN-ACK) packet.

Techniques are provided to detect and correct for packet loops associated with network traffic that passes through a wide-area application services (WAAS) device in a data center network environment. The WAAS device receives a packet from a device in a first data center. The WAAS device determines the directionality of the packet relative to a destination device of the packet. The WAAS device also determines whether the packet has an indicator that associates the packet with the WAAS device. Based on whether the packet has an indicator that associates the packet with the wide area application services device, the WAAS device inserts an indicator within the packet when the directionality of the packet indicates that the packet is to be transmitted across a wide area network (WAN), wherein the indicator comprises information that associates the packet with the WAAS device. The WAAS device forwards the packet to a network based on its directionality.
