....traffic going through the wireless network and we would expect authentication traffic to be a negligible fraction of the overall traffic. We derive the throughput for the wireless network by degrading transmission speeds to account for frame errors using the measurements and analysis performed in [26]. Figure 11 demonstrates that the response times start to climb rapidly at the point at which the KDC saturates and server delay exceeds wireless network delay. The KDC is the bottleneck server in all models. o o o Mobile Clients KDC WAN Wireless Network Proxy App. Server o o o o o o ....

....purpose operating systems as well as general purpose communication paradigms for distributed systems do not cope very well with such types of applications. A major core of the problem has been found in the isolation imposed by layered system and protocol architectures [Ten89, CT90, CWWS92, SS93, XP99] Within this context, we are currently investigating a new concept based on knowledge transfer. Knowledge transfer overcomes the strict layer separation in traditional layered architectures, which is known as the fundamental reason for the architectural drawbacks. Fundamental to the concept of ....

....This scheme avoids link layer error control overhead and outperforms split TCP schemes [5] However, it only works in the direction from the wired Internet towards the wireless host due to its reliance on TCP DUPACKs. In the reverse direction, DUPACKs are returned too late for local error recovery [9]. It is also incompatible with IP security. 3 Single Service Link Layer Performance Link layer schemes are generally preferable to transport layer ones because they provide a local solution to a local problem. They can be customized for the underlying link and deployed transparently to the rest ....

....non congestion losses also occur, due to either wireless bit errors or communication pauses during handoffs. These cause the rate limiting congestion control mechanisms of TCP to be triggered repeatedly even for relatively low error rates, reducing throughput over the bottleneck wireless link [2]. End to end recovery also increases delay, a significant problem for interactive applications. Performance measurements of a 900 MHz WLAN using UDP with 1400 byte packets over an 85 foot distance showed an average error rate of 1.55 with clustered losses [3] TCP generally achieves lower ....
....is to provide transport protocol specific optimizations at the link layer [10] By exploiting transport layer information the link layer can avoid adverse interactions and economize on control overhead. This coupling however limits the applicability of such solutions to specific higher layers [2]. Link layer schemes generally have the advantage of working at the local level, with intimate knowledge of the wireless link and low round trip delays that allow fast recovery. They can be deployed locally, transparently to the rest of the Internet. A TCP study found link layer schemes to ....
