Understanding incentives for prefix aggregation in BGP

Economics of traffic attraction by transit providers

“…Based on the costs of route-processor and line cards for modern Juniper routers, we analyze the amortized monthly cost of storing the extra prefixes (details of the analysis are omitted due to space constraints) and conclude that it is multiple decimal magnitudes lower than the traffic-delivery payment gains from the attraction. This conclusion is consistent with prior game-theoretic analyses of incentives for prefix deaggregation [11]. Therefore, the increased router complexity is not a strong deterrent against the traffic attraction.…”

“…While Bangera and Gorinsky [14] simulate the YouTube prefix-hijacking incident to assess its economic implications, our investigation considers multiple attractors from different transit tiers and evaluates novel countermeasures, such as multi-stage filtering and disconnection. Goldberg et al [10], Kalogiros et al [11], and Levin et al [13] present game-theoretic investigations of economic incentives in inter-domain routing. While these papers provide thorough analyses for small-scale artificial settings, we conduct Internetwide simulations driven by realistic data on inter-domain traffic, topology, and pricing.…”

An analysis of the economic impact of strategic deaggregation

“…Consequently, when thinking about the cost of deaggregation, we need to consider its impact on the global routing system and on the Internet community. Until now, the transit providers did not have the right incentives to refrain from advertising the deaggregated prefixes as injected by their customer [10]. Taking into consideration the monetary aftermath of strategic deaggregation analyzed in this paper, the new economic incentives might be enough to push providers to change their strategy and transfer some of the costs of prefix deaggregation back to their customers.…”

“…Moreover, we assume that the announced prefixes are propagated as injected by the origin i.e. the other ASes honor the origin deaggregation, which is aligned with current operational practices [10]. Additionally, we assume that all the announced prefixes are reachable from every AS in the Internet.…”
