A network device may receive an instruction to update a data structure implemented by the network device and update the data structure based on receiving the instruction. The data structure may include a routing instruction to direct the network device to provide a data flow to a server device for processing. The network device may receive the data flow destined for a destination device; determine the routing instruction based on at least a portion of an internet protocol (IP) address associated with the data flow and based on the data structure; execute the routing instruction to provide the data flow to the server device and to cause the data flow to be processed by the server device to form a processed data flow; and receive the processed data flow and provide the processed data flow towards the destination device.

A network device includes a first and a second control board, with each control board having a separate control plane and fabric plane. The network device is configured to establish an active control plane on the first control board and an active fabric plane on the second control board. The network device is configured to establish a standby fabric plane on the first control board and a standby control plane on the second control board. The network device is configured to detect a failure on the first control board or the second control board and switch the status of the control plane on the second control board from standby to active, when the failure is on the first control board, and switches the status of the fabric plane on the first control board from standby to active when the failure is on the second control board.

The disclosed method for tunneling socket calls across operating systems may include (1) intercepting a socket call issued by an application running on a first operating system, (2) determining that the socket call is directed to a network interface that is (A) accessible to a second operating system installed on a virtual machine running on the first operating system and (B) inaccessible to the first operating system and then, in response to determining that the socket call is directed to the network interface, (3) tunneling the socket call to the second operating system installed on the virtual machine, and (4) executing the socket call within the second operating system to initiate at least one networking action with respect to the network interface on behalf of the application. Various other methods, systems, and computer-readable media are also disclosed.

Systems and methods for tunneling socket calls across operating systems

A network device may receive information regarding a service set identifying service to apply to a data flow received via a particular interface of the network device; receive the data flow via the particular interface; identify a service to provide to the data flow based on the information regarding the service set; identify a processing device to process the data flow; and provide the data flow to the processing device. The processing device may be different than the network device and may process the data flow, on behalf of the network device, to form a processed data flow. The processed data flow may include the data flow with the service applied to the data flow. The network device may further receive the processed data flow from the processing device and transmit the processed data flow toward a destination device.
