This paper describes the main issues arising during the port of the Isabel CSCW application to IPv6. Isabel has been ported to IPv6 in the European IST-1999-20393 LONG project. The port was validated in the distribution of the Madrid Global IPv6 Summit in March 2002. The distribution of the Global IPv6 Summit was a large trial where access to the conference was given with ISABEL running over a network which includes native IPv6 parts, IPv6 over IPv4 tunnels as well as only IPv4 parts. The conclusions obtained are analyzed.
本文描述了Isabel CSCW应用程序移植到IPv6时出现的主要问题。Isabel已经在欧洲IST-1999-20393 LONG项目中被移植到IPv6。该端口在2002年3月马德里全球IPv6峰会的分发中得到验证。全球IPv6峰会的分发是一次大规模的试验，会议的访问是通过ISABEL运行的网络进行的，该网络包括原生IPv6部分，IPv6 over IPv4隧道以及仅IPv4部分。对所得结论进行了分析。

In this paper we design and implement a dynamic bandwidth assignment and an Earth station control system for Internet-like satellite-based communication, which may require different link speeds at different times. Satellite links have limited bandwidth, and for satellite communications to work we have to assign a certain bandwidth to each Earth station. Currently, satellite links have fixed bandwidth assignments. If satellite links are to be used for communication in a manner similar to the Internet, some channels may experience congestion while others do not. In order to improve the usage of all channels a dynamic bandwidth assignment function based on traffic is needed. Use of the system proposed in this paper can improve the usage of satellite channels and reduce the administration cost of Earth stations.

An authorization domain consists of multiple physical devices. Authorizations, such as the right to make a payment or the right to access content are granted to the domain as a whole, but can be exercised from any device in the domain. A device in the domain may have either unconditional or restricted access to the authorizations. Typically, authorizations can be modeled as access to a secret key. In this paper, we discuss the rationales for such an authorization domain, and propose a specific technique to implement authorization domains by sharing the RSA function between a device in the domain and a semi-trusted network server.

The vehicle environment is a good testbed to investigate Internet mobility technologies. Based on testing of buildings, protocol implementation details and problems to deploy it are clarified. This paper describes them. The InternetCAR Project had already done testing to connect vehicles to the IPv6 Internet. Some applications including vehicle diagnosis and teleconference, are implemented on the test system. The test system has the following functions: 1) several communication media with a media switching technology, 2) MobileIPv6 function for continuous connectivity, and 3) network mobility (NEMO) function to provide continuous Internet connectivity for an in-vehicle network. This paper introduces the problems of developing the InternetCAR testing system. The design and solutions are also described.

A public key infrastructure is generally (and effectively) used for cryptographically secure authentication in networks. Ad-hoc networks are formed in a haphazard manner. Security services for ad-hoc networks cannot assume the existence of a particular infrastructure. Peer-to-peer technology is promising in addressing security issues in ad-hoc networks. We provide a novel; cryptographically secure representation of trust based on secure groups - troupes. We show how troupes can be constructed in a distributed manner using RSA accumulators. Troupe-membership is verified using the zero-knowledge protocol of modular exponentiation. Each node in a group has an identity within a group, but it is not required to reveal the identity during verification. This trust model is not centrally controlled and can be deployed incrementally in the network. This paper presents protocols and a prototype implementation of the troup based authentication system.

Various types of certificates are basic tools of modern cryptography and network security. They are used in various protocols, in the form of public key identity certificates, binding a key to its owner or in the form of attribute certificates, being a proof of rights and capabilities of their owner. Management of certificates (creation, distribution, verification, and revocation) is dependent on a certification infrastructure comprising various certification authorities, protocols, and policies. In this paper we consider usage and management of certificates in open, ad hoc networks. Ad hoc networks differ from fixed, wired networks in several important aspects, one of them being that access to the Internet is not always available. This significantly influences certificate management protocols since online access to various certificate system resources (CA certificates, CRL, etc) is not always available. We specify security requirements and constraints in such environments and outline potential solutions for adaptation of certificate management protocols to these new network environments.

Asynchronous transfer mode (ATM) is widely used by many organizations to connect to a wide area network (WAN). ATM supports data, video, and voice simultaneously while providing reasonable quality of service (QoS) as well as flexible management of data traffic. This paper describes "ATM Via Satellite", a SingAREN funded project under the Singapore Broadband 21 Scheme. It was an attempt to implement a satellite ATM network in order to demonstrate the feasibility of implementing ATM over satellite links and to study the level of performance at the application level. The system's performance was analyzed under various link conditions and at different levels of forward error correction. The network consists of a 2.048 Mbps bi-directional geostationary satellite link, two 2.4 m satellite dishes, two satellite modems with G.703 data interface cards and Reed-Solomon modules, and one Cisco Catalyst 7500 ATM switch which connect SingAREN to Temasek Engineering School (where the satellite dishes are located) via the Singapore ONE Broadband Network. The tests showed that it was entirely feasible to implement ATM over satellite links. This paper also discusses the issues involved in the design and implementation of a Satellite ATM network.

Web-services enabled e-marketplaces are based on human initiatives. Initiatives for buying or selling products between customers and merchants or initiatives for supplying products among merchants, in the supply chain. One serious challenge that we continue to face, in spite of growing number of recent contributions in the area of Web-services for e-commerce, is the lack of appropriate support for managing e-marketplace initiatives. As they are subjected to change and evolution, this paper deals with them using an approach for Web-services modeling using processes. The framework models and performs requests for purchasing or providing products, also complex business interactions among merchants involved in the supply chain. By so doing, the Web is transformed into a distributed computational network.
