The Leap Second Behaviour of NTP Servers
نویسنده
چکیده
The NTP network is an important part of the Internet’s infrastructure, and one of the most challenging times for the NTP network is around leap seconds. In this paper we look at the behaviour of public servers in the NTP network in 2005 and over the period from 2008 to present, focusing on leap seconds. We review the evolution of the NTP reference implementation with respect to leap seconds and show how the behaviour of the network has changed since 2005. Our results show that although the network’s performance has certain problems, these seem to be reducing over time.

Network Timing and the 2015 Leap Second
Using a testbed with reference timestamping, we collected timing data from public Stratum-1 NTP servers during the leap second event of end-June 2015. We found a wide variety of anomalous serverside behaviors, both at the NTP protocol level and in the server clocks themselves, which can last days or even weeks after the event. Out of 176 servers, only 61% had no erroneous behavior related to th...
متن کاملThe NTP subnet in New Zealand
The Network Time Protocol (NTP) is used to synchronise the clocks of a significant percentage of the computers that make up the internet. Occasional large adjustments made to the local clock of our department’s main NTP server (kaka) lead us to investigate the state of the NTP subnet in New Zealand. We examined the structure of the NTP subnet within New Zealand, recorded performance information...
متن کاملA study on some properties of leap graphs
In a graph G, the first and second degrees of a vertex v is equal to thenumber of their first and second neighbors and are denoted by d(v/G) andd 2 (v/G), respectively. The first, second and third leap Zagreb indices are thesum of squares of second degrees of vertices of G, the sum of products of second degrees of pairs of adjacent vertices in G and the sum of products of firs...
متن کاملOn leap Zagreb indices of graphs
The first and second Zagreb indices of a graph are equal, respectively, to the sum of squares of the vertex degrees, and the sum of the products of the degrees of pairs of adjacent vertices. We now consider analogous graph invariants, based on the second degrees of vertices (number of their second neighbors), called leap Zagreb indices. A number of their basic properties is established.
متن کاملExperiences with a Survey Tool for Discovering Network Time Protocol Servers
The Network Time Protocol (NTP) is widely used to synchronize computer clocks throughout the Internet. Existing NTP clients and servers form a very large distributed system, and yet the tools available to observe and manage this system are fairly primitive. This paper describes our experiences with a prototype tool that attempts to discover relevant information about every NTP site on the Inter...
