“…In sequencer-based approaches, typically one node is elected as a sequencer and is responsible for ordering messages [13,14,15]. More than one sequencer can be present, but only one will be active or relevant at a time [16,17].…”

Abstract. We describe a method to order messages across groups in a publish/subscribe system without centralized control or large vector timestamps. We show that our scheme is practical-little state is required; that it is scalable-the maximum message load is limited by receivers; and that it performs well-the paths messages traverse to be ordered are not made much longer than necessary. Our insight is that only messages to groups that overlap in membership can be observed to arrive out of order: sequencing messages to these groups is sufficient to provide a consistent order, and when publishers subscribe to the groups to which they send, this message order is a causal order.

“…There are a lot of multicast protocol which support at least one of the above discussed features, e. g. RMP [9], SRM [7], RMTP [8], and others, but there are only a few protocols which support all three features: the Reliable Multicast Protocol RMP and the Totem Protocol [6]. Both protocols use a token mechanism and different ordering schemes.…”

“…IP multicast, however, uses a receiver related multicast paradigm which is not suited for closed groups. Protocols which are based on this paradigm like RMTP [8] and RMP [9] cannot be used to replace GCP although they in part support the required properties. A mapping of GCP on point-to-point connections is not acceptable, because it increases the group management and the network load for larger groups.…”

Video conferences have become a popular application in modem high performance networks. Advanced technologies allow their installation on desktop computers. Currently videoconferences are mainly deployed for large open group conferences in the Internet to transmit lectures, conferences, talks, and discussions. Multiparty video conference tools for c10sed group meetings are less broadly used. On the other hand, most meetings in every-day life are meetings of closed groups with a more or less confidential character. UnJike open group conferences cJosed group meetings require asender related transmission paradigm, i.e. the sender must know the receivers ofthe data streams. This is usuaHy solved by using a centralized group server for the group and the QoS management. The shortages of this approach are server failures and performance problems. The decentralized approach is more flexible, but it requires more sophisticated mechanisms to preserve the consistency ofthe management data at each participant. In the paper we present the signalization protocol GCP to support decentralized c10sed group video conferences. It provides an atomic, ordered, and reliable data delivery service and supports a dynamic join and leave ofparticipants. We present two versions of the protocol: one for A TM networks using overlaid multi cast connections and one for IP-based networks.

“…A variety of reliable protocols have been proposed for multicast data delivery, each with an emphasis on particular types of applications, network characteristics, or definitions of reliability ( [1], [2], [3], [4]). In this tradition, Pragmatic General Multicast (PGM) is a reliable transport protocol for applications that require ordered or unordered, duplicate-free, multicast data delivery from multiple sources to multiple receivers.…”
