Abstract:
1. A method comprising: receiving, via a router device, a packet that includes header data; determining, via the router device, descriptor data relating to the header data; generating, by a first processing unit associated with the router device, first header data for the packet based on the received header data and the descriptor data, where the first header data includes an identifier of a next network device to receive payload data in the packet; writing, via the router device, the first header data for the packet to a first buffer; generating, by a second processing unit associated with the router device, second header data for the packet based on the received header data and the descriptor data, where the second header data includes data associated with routing the payload data from the router device to the next network device; writing, via the router device, the second header data for the packet to a second buffer; and after the first header data is written to the first buffer and after the second header data is written to the second buffer, transmitting, by the routing device, a modified packet that includes the first header data, the second header data, and the payload data, where the modified packet is longer, in packet length, than a maximum transfer unit (MTU) of an output interface associated with the router device, and where transmitting the modified packet includes:
