In this paper, we extend NS-2 to simulate Micro-Mobile MPLS frameworks. The extension supports most of the important mechanisms used in the literature. The simulator is based on IEEE 802.11. The important mechanisms for IEEE 802.11 in our module are multi-channel, directional antennas, multiple interfaces, L2-handoff, L2-trigger, bicasting, pre-established LSP, and buffering mechanism. MPLS modules used in this simulator is based on MPLS module (MNS) [8]-[10]. This simulator could be configured to assess performance of Mobile MPLS protocols such as micro mobility-enabled multiprotocol label switching (M-MPLS) [21], fast handoff (FH) and master forwarding chain (MFC)-Micro Mobile MPLS [2], [23] and MiM-MPLS [30]. The simulator is validated for each mechanism. The validation results follow to the theory.

In this paper, we present a comparison of reliable multicast transport protocols for GEO satellite networks. The performance is analyzed by using general design principle of end-to-end transport protocols, mathematical model and simulation model. The mathematical model is used to present approximated performance. The simulator is implemented to support 3 types of medium access control protocols and 3 types of loss models. We consider 3 end-to-end reliable multicast transport protocols. These protocols present most of reliable multicast transport protocols' design issues for satellite networks such as forward error correction, congestion control, feed back control, feed back adaptation. Our goal is to understand the performance in several aspects of reliable multicast transport protocols in different environments.
