high bandwidth-delay products and random loss. IEEE/ACM Trans. on
Networking, 5(3):336-350, 1997
... The following key results are obtained. First, random loss leads
to significant throughput deterioration when the product of the loss probability
and the square of the bandwidth-delay product is larger than one. Second,
for multiple connections sharing a bottleneck link, TCP is grossly unfair
toward connections with higher round-trip delays. ... Finally, while the
recent Reno version of TCP produces less bursty traffic than the original
Tahoe version, it is less robust than the latter when successive losses
are closely spaced. ...

presence of a reliable end-to-end transport protocol. ... We quantify the
increased load on the link due to competing retransmission strategies,
and, for a transport protocol modeled on TCP, we identify the region of

of both reducing end-to-end throughput and increasing link utilization
in the network segment where bandwidth is the most expensive.

In this paper, we compare several schemes designed to improve the
performance of TCP in such networks. We classify these schemes into three
broad categories: end-to-end protocols, where loss recovery is performed
by the sender; link-layer protocols that provide local reliability; and
split-connection protocols that break the end-to-end connection into two
parts at the base station. We present the results of several experiments
performed in both LAN and WAN environments, using throughput and goodput
as the metrics for comparison.

... This paper describes the interworking of DECT with Mobile IP
[3] to support subnet-level mobility, while DECT is employed for user mobility
within a subnet. To achieve an efficient interworking, we exploit and take
advantage of the mobility features of DECT, which offers faster convergence
and far fewer overheads. Hence, the Mobile IP handover latency can be reduced
to improve the performance of transport protocols (e.g., TCP). We define
the necessary protocol signalling for the DECT-Mobile IP interworking mobility
management procedures, which require no modification to both DECT and Mobile
IP.
