Abstract: Techniques for identifying network congestion and adapting network performance to relieve the network congestion are described. As described, a network element such as a switch reports network congestion indicators such as link level control frames to a network controller. The network controller uses the network congestion indicators reported from the network elements to identify congestion points, data traffic, and data flows experiencing congestion at a network level. The network controller then determines optimized control parameters for the network in order to reduce or alleviate the congestion at the congestion points.

Abstract: Buffer designs and write/read configurations for a buffer in a network device are provided. According to one aspect, a first portion of the packet is written into a first cell of a plurality of cells of a buffer in the network device. Each of the cells has a size that is less than a minimum size of packets received by the network device. The first portion of the packet can be read from the first cell while concurrently writing a second portion of the packet to a second cell.
