Tomas Henriksson tomhe@ifm.liu.se Implementation ARP Entity (report received)

A hardware ARP entity has been specified, implemented and verified. This hardware accelerator can reduce the load on the main CPU in an IPv4 host attached to an Ethernet LAN. The static timing analysis show that the accelerator could be used even in 10 Gigabit Ethernet. The ARP entity cache consists of at most 8 entries. An aging mechanism has been implemented.

Laila Daniel g-laida@ida.liu.se Paper (received) Schemes for improving TCP performance in wireless and mobile computing environments

Reliable transport protocols like TCP is best suited for wired networks where the packet losses are mainly due to congestion. wireless networks are characterized by losses due to transmission errors and handoffs. TCP interprets these losses as congestion and invokes congestion control mechanisms which in turn degrade the performance. in this paper we discuss about the performance degradion of TCP in wireless and mobile networks and some proposed schemes to improve TCP performance.

Jean-Paul Baaklini Paper Dynamic Routing Protocols

I would like to present a term paper about dynamic routing protocols: distance vector protocols, link state protocols and the eventuals advantages of a hybrid protocol based on both algorithms.

Ioan Chisalita g-ioach@ida.liu.se Paper (received) Voice Over IP

The IP telephony concept is growing bigger and the number of companies interested is continuously increasing. The fact that it is possible to route traditional calls over IP networks by using gateways is a reality now. Both the ITU and the IETF are involved in the standardization, and their protocols are competing to become the de facto standard. The paper give an overview about important issues that are involve in Voice communication over IP networks. The paper structure is presented in the following. In the first section an introduction is given to reveal today status of voice transmission using IP Networks. The second section decribe 3 application in order to show the usability of this technique. The third section give a more detailed description of the voice over packet networks architecture. The fourth section describe briefly the protocols involve in Voice over IP and give a comparation between SIP and H.323. The fifth section deal with QoS in Voice Over IP applications. The last section give some conclusions regard voice application in IP based Networks.

Lin Han linha@ida.liu.se Implementation Claudiu Duma cladu@ida.liu.se (report draft received) Reliable Multicast File Transfer Protocol

RMFTP is a file transfer protocol using push technology to deliver files from one sender to multiple recipients at the same time. To achieve efficiency, RMFTP employs multicast technology rather than unicast. Since IP multicast provides no guarantee that the transmitted IP datagram really achieves the destination, RMFTP, as a transport layer protocol, provides reliability.

Jon Edvardsson joned@ida.liu.se Implementation Simple NFS server (report received)

In a distributed environment it is important that information can be moved between computers. The Network File System is a protocol based on the TCP/IP protocol suit, and allows users to share files over a network. As an exercise in the Ecsel course on TCP/IP, I implemented a simple NFS server. The server, which supports a small part of the NFS v2, allows you to mount a directory structure, and to read files and directories.
