Ascertaining per-hop network characteristics

摘要

A tool that may be used for querying and obtaining per-hop information along a network path, and/or for verifying the host name of each hop against a data repository such as the DNS. The query and response may be transmitted in, e.g., the destination options header of data packets, such as an IPv6 destination options header.

主权项

1. A method, comprising:
receiving, at a network node, a first data packet comprising an options header indicating a first option type; performing, at the network node, a query based on a value of the first option type for autonomous system number (ASN) information associated with the network node; determining, via the network node, that the network node is a deepest node; and sending, from the network node, a second data packet comprising an indication that the network node is the deepest node and the ASN information associated with the network node.
