Hi All, LISP+CONS and ALT are based on tree-hierarchy overlay, and the initial traffic will be allowed to travel along the overlay in order to avoid initial packets loss. However, this approach not only results in a longer forwarding path but also a high forwarding pressure on the highest-level nodes (like honey point). The initial traffic volume is not in the same magnitude with the query messages in DNS hierarchy.
APT and ivip, based on the anycast idea, not only avoids the long path and large-latency for the initial packets but also share the initial traffic pressure among the different default mappers. However, they are not so scalable to support host or micro-net granularity. Could we consider some tradeoff between these two approaches? For example, replace the default mapper with multiple mappers which are responsible for different address-prefix blocks in APT and ivip, or allocate multiple highest-level nodes in CONS or ALT, which are responsible for the same address block, to many different network locations.
