“…This series of locally optimal forwarding decisions will establish a route that is close to the optimal route. Another vision for path minimization consists in favoring ISLs with higher lifetime to reduce the additional delays that may be caused by ISLs handovers [15], [16].…”

Non-geostationary (NGEO) satellite communication systems offer an array of advantages over their terrestrial and geostationary counterparts. They are seen as an integral part of nextgeneration ubiquitous communication systems. Given the non-uniform distribution of users in satellite footprints, due to several geographical and/or climatic constraints, some Inter-Satellite Links (ISLs) are expected to be heavily loaded with data packets while others remain underutilized. Such scenario obviously leads to congestion of the heavily loaded links. It ultimately results in buffer overflows, higher queuing delays, and significant packet drops.To guarantee a better distribution of traffic among satellites, this paper proposes an explicit exchange of information on congestion status among neighboring satellites. Indeed, a satellite notifies its congestion status to its neighboring satellites. When it is about to get congested, it requests its neighboring satellites to decrease their data forwarding rates by sending them a self status notification signaling message. In response, the neighboring satellites search for less congested paths that do not include the satellite in question and communicate a portion of data, primarily destined to the satellite, via the retrieved paths. This operation avoids both congestion and packet drops at the satellite. It also ensures a better distribution of traffic over the entire satellite constellation. The proposed scheme is dubbed "Explicit Load Balancing" (ELB) scheme.While the multi-path routing concept of ELB has many advantages, it may lead to persistent packet reordering. In case of connection-oriented protocols, this phenomenon results in unnecessary shrinkage of the data transmission rate. A solution to this issue is also incorporated in the design of ELB. The interactions of ELB with mechanisms that provide different QoS by differentiating traffic (e.g., Differentiated Services) are also discussed. The good performance of ELB, in terms of better traffic distribution, higher throughput, and lower packet drops, is verified via a set of simulations using the Network Simulator (NS).

“…In attempt of supporting QoS in NGEO satellite constellations, several researchers have first considered the integration of satellite networks with the Asynchronous Transfer Mode (ATM) as it originally provides different levels of QoS guarantees [3] [4]. However, the overwhelming growth of applications based on the Internet Protocol (IP) has attracted the attention of satellite operators to IP traffic.…”

Due to geographical and/or climatic constraints, the community of future satellite users will exhibit a significant variance in its density over the Globe. This density variance will yield a scenario where some satellite links are congested while others are underutilized. To ensure an intelligent engineering of traffic over satellite networks, this paper proposes a routing protocol that enables neighboring satellites to explicitly exchange information on their congestion status. A "soon-to-be-congested" satellite requests its neighboring satellites to decrease their data forwarding rates. In response, the neighboring satellites search for less congested paths that do not include the satellite in question and communicate a portion of data, primarily destined to the satellite, via the retrieved paths. By so doing, congestion, and the resulting packet drops, can be avoided. A better distribution of traffic among satellites can be guaranteed as well. The proposed scheme is dubbed "Explicit Load Balancing" (ELB) scheme. A set of simulations is conducted to evaluate the performance of the ELB scheme using the Network Simulator. In terms of Quality of Service, encouraging results are obtained: better traffic distribution, higher throughput, and lower packet drops.

“…And when satellite failure is the change of topology structure under the unusual situation the route also need recalculating. In addition, when link congestion causes the change of link weights, the route need recalculating [14]. Under timeslot switching, satellite failure and link congestion, route calculation takes many optimization measures like jitter optimization algorithm and preferred transmission algorithm of backbone network.…”

with proportion of multimedia services in the IP satellite network growing, how to provide these services with effective guarantee of QoS metrics such as delay, bandwidth, delay and jitter is a crucial issue in IP satellite networks. Based on LEO/MEO network model, this paper proposed an algorithm of QoS cost collection and calculation separation which simplifyies routing calculations and reduces the convergence time of route calculation, analyzed routing recalculation strategy under the circumstances of timeslot switching, satellite failures and link congestion, and aiming at route recalculation strategy in different situations put forward optimization schemes such as jitter optimization algorithm and prior transmission of the backbone network algorithm. Simulation results show that optimization schemes can take QoS guarantee requirements into account, balance QoS indicators like delay, delay jitter, bandwidth so as to better meet the demand of QoS route in case of the asymmetric flow.
