* 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.
