  • Publication number: 20130339727
    Abstract: 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. For example, VDI traffic may be intercepted and all data redundancy elimination messages may be encrypted and sent to a peer network device.

  • Publication number: 20130238811
    Abstract: Systems and methods are disclosed for the acceleration of UDP traffic. tive action may be taken. Dynamic TCP tunnels may be established as the traffic flows from a source to a destination device. As the present approach is dynamic, the operational complexities are drastically reduced/eliminated. High availability systems become much easier to implement with acceleration that is dynamic and adapts to the traffic flow.

  • Publication number: 20130163470
    Abstract: In one embodiment, a method includes receiving a TCP (Transmission Control Protocol) packet at a service device configured to optimize traffic over a network link, inserting a discovery identifier in the TCP packet, encapsulating the TCP packet in a UDP (User Datagram Protocol) packet, and transmitting the UDP packet over the network link. An apparatus is also disclosed.

  • Publication number: 20130073743
    Abstract: In one embodiment, a method includes receiving session information at a traffic interceptor in communication with a plurality of service devices, the session information transmitted from one of the service devices and identifying flows associated with a session and the service device associated with the session, storing the session information at the traffic interceptor, and transmitting traffic received at the traffic interceptor to the service device selected based on the session information. An apparatus is also disclosed.

  • Publication number: 20130031269
    Abstract: 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.

  • Patent number: 8254273
    Abstract: 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.
