Abstract: The present disclosure relates to methods and systems for dynamically changing an advertised window for a transport layer connection. A device can receive data from a server destined for an application. The device identifies the size of the application buffer corresponding to the application and advertises the application buffer size as a window size to the server. The device stores the data in the device memory. The device then determines the memory usage by comparing the memory usage to one or more predetermined thresholds. If the device determines that the memory usage is below a first predetermined threshold, the device can implement an aggressive dynamic receive buffering policy in which the device increases the advertised window size by a first increment. If the device determines that the memory usage is above the first threshold and below a second threshold, the device executes a more conservative dynamic receive buffering policy.

Abstract: A network device includes a Network Interface Device (NID) and multiple servers. Each server is coupled to the NID via a corresponding PCIe bus. The NID has a network port through which it receives packets. The packets are destined for one of the servers. The NID detects a PCIe congestion condition regarding the PCIe bus to the server. Rather than transferring the packet across the bus, the NID buffers the packet and places a pointer to the packet in an overflow queue. If the level of bus congestion is high, the NID sets the packet's ECN-CE bit. When PCIe bus congestion subsides, the packet passes to the server. The server responds by returning an ACK whose ECE bit is set. The originating TCP endpoint in turn reduces the rate at which it sends data to the destination server, thereby reducing congestion at the PCIe bus interface within the network device.

The neighboring network element can determine whether the version of the link-state database is greater than or less than a copy of the link-state database stored by the neighboring network element. If the requested version number is less than the neighboring network element's link-state database version number, then the neighboring network element can send changes to the link-state database since the requested link-state database version number.
