....This results in a more regular window increase than with ACK loss. In addition, sender modi cations are proposed to make the data tra c less bursty, even when ACKs open the window in large steps. Another proposed solution involves the reconstruction of the ACK stream at the far end of the up link [21, 24]. 40 8.4 Wireless Networks In this section, we discuss the performance issues faced when using TCP over wireless links, and the di erent approaches proposed for addressing them. The main problem faced in the wireless context is the e ect of the relatively high transmission error probability on ....
....for addressing this problem include intercepting and ltering duplicate ACKs on the return path. However, this restricts this solution to the last hop before the destination, otherwise it might prevent the detection of real congestion loss further downstream along the path of the connection [4, 9, 22, 24]. The second approach attempts to address the transmission error problem at the TCP level. In addition to the general improvements to TCP s congestion control mechanisms (e.g. Fast Recovery, SACK) several techniques have been proposed to speci cally deal with this problem. The rst involves ....

....4, 5 and 6. Currently, the e#ects of congestion on returning ACKs are ignored. Loss of ACKs can be prevalent on links where the available bandwidth on the source to the destination link to di#erent to the bandwidth from the destination to source, one example of this is a satellite connection[1]. Accounting for ACK congestion will be done by creating a second (ACK) stream whose performance a#ects the first stream s. C. Modelling Switches Switches are modelled as a number of switch elements. Each element is essentially a bu#er with minimal management features. The switch object contains ....

The probability of the kth stream being dropped P drop is given by6 #(k = x) # # # # # # # P drop [1] = B inst [1] BSwInst x = 1 .

The switch identifies the TCP segment the packet loss will occur in, ....

....and to utility optimization. A survey on modeling and analysis of TCP can be found in [9] The TCP protocol itself, its performance problems (e.g. negative impact of transmission errors and asymmetric paths) and the body of the literature proposing solutions to these problems are explained in [11]. 3 The model Let X(t) be the transmission rate at time t. In case of TCP, it is equal to the current window size divided by the Round Trip Time of the connection. Let K = f1; 2; Ng be the set of possible states of the path. We allow losses to occur in any of the N states; the probability ....
