“…Its basic idea is to maintain a hybrid multi-part group communication tree by extending single source multicast control messages. Like SLIM [6] , a channel identifier <s, c>, which can support MACMPG, is published in certain ways (via web pages, etc). s is a addressable IP address which can be a real host address or a virtual IP address not corresponding to any host.…”

To solve the problems of current IP multicast which includes poor inter-domain many-to-many group support, security vulnerabilities and dependency to specific multicast infrastructure, a mobile accessible closed multi-part group (MACMPG) communication protocol in IPv6 network is proposed. By extending the single source multicast protocol, the communication channel for multi-part group communication across domains is established. Based on IPv6 CGA, the secure closed group communication scheme is designed. The access to the multicast traffic only confined to the authorized senders and receivers and only trusted routers are allowed to be the branch points of MACMPG tree. By tunneling mechanism, the MACMPG traffic can be transmitted across non-MACMPG routing area, and the mobile nodes can join the group remotely and roam freely between domains, which eliminates the dependency on specific IP multicast routing.New applications in the Internet have increasing demand for multi-part group communication. However, the current IP multicast models have poor support for inter-domain many-to-many group communication, and they are vulnerable to various attacks and dependent to specific multicast routing [1,2] . Currently there is no feasible and widely deployed scheme for accorss-domain multi-source multicast. Recent years, the researchers have attempted to support multi-source applications using SSM (source specfic multicast). But they have some flaws in one way or another. The multi-channel SSM [3] has poor scalability; the relay-based SSM [4] has the single-pointof-failure problem, or it can form traffic aggregation at the relay node and the links around it and then cause high packet loss ratio; SSM-Extension [5] is complex and unscalable, and it consumes lots of time when forming the bi-directional tree.A self-configuring lightweight internet multicast (SLIM) protocol is proposed in Ref. [6]. Its main idea is the nodes and routing areas that do not support multicast can be bypassed by tunnelling mechanism. It is scalable and easy to be employed. But SLIM is only suitable for one-to-many group communication applications. In addition, a concrete solution to tackle the security problem was not proposed.In this paper, a mobile accessible closed multi-part group (MACMPG) communication scheme in IPv6 network is proposed. By extending SLIM's control message, a hybrid multi-source-multi-receiver multicast tree

“…The gTrace state is identified by the root of the multicast tree and a group identifier. In single source multicast [17,18] this is the channel identifier. In PIM-SM and other shared tree approaches, the root of the multicast could be the rendezvous point, or the root of any of the source specific trees.…”

Abstract. For multicast to be a viable as a dependable network service, mechanisms for monitoring and managing multicast flows must be developed. Significant prior work exists to use receiver observations to derive properties of multicast groups, including the underlying distribution topology and membership size. However, just as multicast is delegation of replication and distribution from the sender into the network, we contend that similar delegation of monitoring and management into the network is warranted and beneficial. gTrace is a set of mechanisms to monitor multicast distribution trees that operates on routers participating in the multicast distribution to obtain accurate observations throughout the tree in a scalable manner. In this paper we present the protocol and validate its benefits through analysis, simulation and experimentation.

In particular, we aim to build on our prior and ongoing work on active and programmable networking [1,2] and self-configuring services [3,4], rapid restoration [5,6,7], and service dependability [8].

Abstract. Wireless ad-hoc networking is increasingly seen as critical part of ubiquitous self-configuring networking environments, including home and sensory networks and networks required to support ideas of pervasive computing. While basic principles of networking remain intact the large number of networked elements many of which exhibit mobility while being limited in power and other aspects introduces challenges not seen in traditional networks. The complexity of these future networks is further aggravated as increasing flora of applications exploit increasing diversity in of network and user equipment. Ad-hoc networking requires these devices to play a dual role of an end-system acting in its own interests and also the role of a router forwarding package on behalf of other devices. We foresee a wide range of operating environments from highly volatile -with rapidly moving mobiles and fluttering availability, to semi stable sensory environments -where node failures or external changes are the primary sources of network volatility. FrameworkWe have recently started a project on ad-hoc networking focused on scalability and dependability and flexibility by targeting three main areas: reachability and routing, aggregation of routing information and on nodal architecture and operating system support for the duality required for the networked elements. While based on our own prior work and that of others, the project is in its early stages with limited amount of results so far. This abstract briefly describes the project, our approaches and our preliminary results.The research is conducted at the Network Systems and Services Laboratory at Reykjavík University, lead by Dr. Gísli Hjálmtýsson, professor of Computer Science. The effort constitutes a new direction for our research on network and router architectures, and novel network systems and services. In particular, we aim to build on our prior and ongoing work on active and programmable networking [1,2] and self-configuring services [3,4], rapid restoration [5,6,7], and service dependability [8]. In addition to Professor Hjálmtýsson, Prof. Heimir Þór Sverrisson and two Ph.D. students are involved at this early stage of the project.
