....loop. Finally, when the DMA write completes for packet #2, the NIC informs the device driver of the new packet in the main memory. 3.1. 3 Released Tigon Firmware Alteon Websystems, the original manufacturer of the Tigon, released several versions of the Tigon firmware as open source software [2]. This released firmware is event driven, consisting of an event dispatch loop and a set of event handlers as described in Section 3.1.2. Using the PRI instruction, the event dispatch loop prioritizes events according to the order of the corresponding bits in the event register. Table 3.1 ....

....state: either waiting for a new connection or waiting for new requests on an existing connection. Batching is disabled when new work arrives until all child processes become idle again. We batch packets by leveraging the interrupt coalescing feature in the A1 teon ACEnic Gigabit Ethernet card [1] on the web server. Interrupt coalescing groups the interrupts for a set of packet events (reception or transmission) into one single interrupt to the host processor and was introduced to improve network through put by reducing interrupt processing overheads [1] We modified the ACEnic device ....
....teon ACEnic Gigabit Ethernet card [1] on the web server. Interrupt coalescing groups the interrupts for a set of packet events (reception or transmission) into one single interrupt to the host processor and was introduced to improve network through put by reducing interrupt processing overheads [1]. We modified the ACEnic device driver to allow the packet count and timeout for interrupt coalescence to be modified dynamically using an ioctl call. To validate Salsa, we conducted an experiment where the prototype batches requests with a timeout of 100 milliseconds or a maximum backlog of 100 ....

....At that point, the NIC may transmit the packet. Finally, when the DMA write completes for packet #2, the NIC must inform the device driver of the new packet in the main memory. 3. 2 Released Tigon Firmware Alteon Websystems released several versions of the Tigon firmware as open source software [1]. This released firmware is event driven, consisting of an event dispatch loop and a set of event handlers. The event dispatch loop prioritizes events according to the order of the corresponding bits in the event register. If no bits are set, the event dispatch loop repeatedly polls the event ....

....lines in the sendfile system call and mbuf manipulation routines, and roughly 850 lines of new code in the device driver for the network interface. The network interface in the server uses a modified version of Revision 12.4. 13 of the Tigon firmware, which was made open source by the manufacturer [1]. The modified firmware implements the API commands of Section 4.3 and various optimizations to eliminate the possibility of the NIC being a potential bottleneck. Specifically, the modified firmware parallelizes tasks across the two processors and sets tunable parameters to communicate with the ....
