BGP Prefix Delegations
Thomas Krenc, Anja Feldmann · 2016
Among the scalability limits in the Internet routing ecosystem are the BGP routing table size and the rate of updates. In this paper, we focus on the former. The BGP routing table size has been growing superlinearly in the past decades. Although the address space allocation was structured with aggregation in mind, this capability is impaired due in part to the need for traffic engineering. One major impairment are delegated prefixes.
