A dynamic fair-share buffer policy is needed tackling Incast. In contrast to shared buffer switch architecture, a dedicated buffer guarantees equal space to each port, and thus, provides a fair-share buffer. However, small dedicated buffers lead to Incast—they cannot handle a traffic burst for a short time.
Jan 6, 2019 · We present a software-defined technique tackling the many-to-one communication pattern-Incast-in a data center storage cluster. Our proposed ...
Incast is a phenomenon when multiple devices interact with only one device at a given time. Multiple storage senders overflow either the switch buffer or ...
The proposed method removes the TCP saw-tooth behavior, provides a global flow awareness, and implements the dynamic fair-share buffer policy for end-to-end ...
In order to improve throughput, our idea is avoiding packet losses before TCP in cast happens. The scheme is limiting the number of concurrent senders such that ...

TCP Throughput Collapse, also known as Incast, is a pathological behavior of TCP that results in gross under-utilization of link capacity in certain ...
Packet buffers in datacenter switches are shared across all the switch ports in order to improve the overall throughput. The trend of shrinking buffer sizes in ...
§5.5.2 evaluates DIBS with dynamic buffer allocations. Switches can also have a combined Input/Output queue. (CIOQ) [53]. Since these switches have dedicated ...
