BDP can refer to the product of bandwidth and one-way delay or RTT, depending on the context. One includes air rings localized at each side of the line defect and the other modifies the radius and distance of holes at each side of the waveguide. Is this a correct statement? If not, can you please describe the relationship between the TCP receive window size & the bandwidth delay product. Then the product of bandwidth and RTT is the number of bits 'in-flight' before the sender can expect to hear back from the receiver. In this paper, we propose the use of two two-dimensional photonic crystal line defect waveguides for slow light with large delaybandwidth product (DBP). Ergo, the TCP receive window size is the limiting factor. In this scenario, with my current understanding, even if I increase bandwidth, & even if I stretch the pipe out by adding latency, the throughput will never exceed the TCP receive window size. So our bandwidth delay product is 2.86 times greater then the TCP receive window size. The default TCP receive window is 65,535 Bytes. So let's convert our previous example from bits to bytes we get 187,500 Bytes. We experimentally evaluated a record high value of 57 (a 40 ps delay and a 1.4 THz bandwidth). One is concerning the delay-bandwidth product, indicating the buffering capacity of the device. In TCP/IP illustrated Stephens seems to suggest that if the bandwidth delay product is larger then the TCP receive window, that the TCP receive window is the limiting factor. This paper reports two advances in a slow light device consisting of chirped photonic crystal slab coupled waveguide on SOI substrate. I have also seen the bandwidth delay product compared to the TCP window receive size. So this says that theoretically, under optimal conditions, on a 15Mb pipe, a single TCP session cannot consume more then 1.5 Mbps (note theoretical). I am trying to wrap my head around exactly what the bandwidth delay product says about TCP performance.Д«andwidth delay product is defined as capacity of a pipe = bandwidth (bits/ sec) * RTT (s) where capacity is specific to TCP and is a bi-product of how the protocol itself operates.ДЄssume we have a 15Mb pipe with 100 ms of latency.
