Network synchronization plays a central role in digital
telecommunications. It determines the quality of most services provided
by the network operator. Traditionally, synchronization has been
distributed across telecommunications networks using the TDM links for
which the networks were designed (i.e. E1 and DS1 circuits).
Several fixed and mobile Operators are migrating to a next-generation
network (NGN) with IP packet-switched network infrastructure. Ethernet
transport is becoming increasingly commonplace. This trend is driven by
prospected lower operative costs and by the convergence between fixed
and mobile services. However, migrating trunk lines to IP transport
poses significant technical challenges, especially for circuit emulation
and synchronization of network elements.
The evolution of communications networks towards packet-switching has
increased interest in the distribution of synchronization using packet
methods. This has a twofold impact:
1) synchronization distribution over packet networks using packet-based
methods has become a focus of activity in the standards bodies (ITU-T
G.8261/2/3 and IEEE 1588);
2) the traditional model, in which synchronization distribution is
engineered carefully for optimal performance, may give way to scenarios
in which there is a greater expectation of ad-hoc synchronization
quality achieved without as much need for provisioning as has
traditionally been the case – similar to Ethernet "plug and play".
The latter point widens the scope of interest in synchronization beyond
specialists to the wider audience of telecommunications engineers. A
striking example is the distribution of synchronization to
next-generation wireless base-stations, which are connected to the core
network only via packet-switched networks, but still require highly
accurate synchronization to meet service quality expectations.

*Scope of contributions *

The scope of the issue includes, but is not limited to the following
topics of interest:
- key emerging standards in the area of synchronization over packet
networks;
- timing scenarios in various network applications;
- tutorial papers describing packet network characteristics which
impact synchronization transport;
- implementation challenges in achieving high-quality synchronization
using the new technologies;
- carrier and vendor experience in deployment;
- measurement techniques for characterizing and qualifying
packet-based synchronization.

**Submission Guidelines*
Articles should be tutorial in nature, with the intended audience being
all members of the communications technology communities. They should be
written in a style comprehensible to readers outside the specialty of
the article. Mathematical equations should not be used (in justified
cases up to three simple equations are allowed). Articles should not
exceed 4500 words. Figures and tables should be limited to a combined
total of six. The number of references is recommended to not exceed 10
(maximum 15). Complete guidelines for preparation of the manuscript are
posted at http://www.comsoc.org/livepubs/ci1/info/sub_guidelines.html.
