An intermediate network device performs service aware path selection. For example, the intermediate network device comprises a network interface that receives network traffic and a control unit that couples to the network interface. The control unit comprises a storage medium that stores a first set of cost factors for a first path from the intermediate network device to another intermediate network device. The first set of cost factors includes at least one optimization cost factor corresponding to intermediate optimization capabilities available to the intermediate network device that offset other cost factors of the first set. The storage medium also stores a second set of cost factors for a second path between the devices. The control unit selects either the first path or the second path over which to forward the network traffic based on the first and second sets of cost factors.

Service aware path selection with a network acceleration device

A network device is configured to monitor a data size of data transmitted to a particular destination during a particular time period, determine, based on the monitored data size, an average data size for the particular destination and for the particular time period, establish a data connection toward the particular destination during the particular time period, set an initial data size for the data connection based on the average data size, and transmit data on the data connection in an amount equal to the initial data size.

Setting initial data transmission size based on prior transmission

In general, techniques are described for adaptively applying network acceleration services within an intermediate network device. In particular, the intermediate network device comprises a classifier module that receives network traffic and a servicing engine. The servicing engine applies the network acceleration services to the network traffic in accordance with a service configuration and monitors the application of network acceleration services to determine whether the application of each of the network acceleration services improves the efficiency with which the network traffic is serviced. The servicing engine then dynamically adapts the service configuration to alter the application of the network acceleration services based on the determination. Thereafter, the servicing engine applies the network acceleration services to the network traffic in accordance with the dynamically adapted service configuration to more efficiently service the network traffic.

Adaptively applying network acceleration services with an intermediate network device

A network optimization device may receive a stream of data and identify a selected compression dictionary from among a number of compression dictionaries based on the received stream of data. A receiving network device may be notified regarding the selected compression dictionary. The stream of data may be compressed using the selected compression dictionary and transmitted to the receiving device.

Network characteristic-based compression of network traffic

A device may receive a packet at a network device, and may retrieve from a table, by using information in a header of the packet as keys, records that include communication performance statistics associated with transport protocols. In addition, the device may select, based on the records, a transport protocol with an optimum communication performance statistics among the transport protocols and send the packet in accordance with the selected transport protocol from the network device.

Multi-link transport protocol translation

A network system includes a first device and a second device separated by a network having asymmetric routes in which traffic forwarded in a first direction from the first device to the second device may travel a different route than traffic forwarded in a second direction from the second device to the first device. At least three intermediate processing devices are located between the first device and the second device, wherein at least two of the intermediate processing devices are located along different asymmetric routes. The intermediate processing devices intercept a communication flow between the first device and the second device, and encapsulate the communication flow within network tunnels so that communications associated with the communication flow in the first direction and the second direction are forwarded between a same set of at least two of the intermediate processing devices.
