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.

Accelerating UDP traffic

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.

Wide-area application services device to determine packet loop errors in a data center that communicates over a wide area network

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.
