The primary role of the Mailbox server is to host mailbox databases where the recipient mailboxes are hosted. But in Exchange Server 2013, there’s more done besides hosting those mailboxes. The Hub Transport service is also running on the Mailbox server, and this service is responsible for all SMTP message routing in the Exchange organization. The Unified Messaging (UM)service is also part of the Mailbox server role, and there's a Client Access service (CAS) running on the Mailbox server as well. As explained in the previous chapter, the Client Access server is a stateless protocol proxy, proxying user requests to the Mailbox server; this is the server where all processing takes place. But in Exchange 2013, the business logic was moved from the Client Access server to the Mailbox server. This is the reason you’ll find the Autodiscover section in this chapter instead of in Chapter 3.

Now that we’ve covered some of the new functions of Exchange Server 2013 and provided some background information, it’s time to move on to actually installing Exchange 2013 and getting it working. In this chapter I will cover installation of both the Mailbox server and the Client Access server (CAS), including the prerequisite software. Installation can be performed using the GUI or from the command line, fully unattended. This chapter covers new, “green-field” installations. Chapter 3 covers upgrades from a previous version of Exchange Server.

Data dictionaries serve to identify and describe STAR File data items which are exchanged and archived. When STAR Files are written or read, dictionaries can play an important supplementary role of validating individual items and checking the overall conformance of the data structure. A STAR File dictionary contains definitions for each data item. These definitions are composed of a sequence of data attributes which, individually and collectively, specify the properties of an item. These attributes are considered to be the vocabulary of a STAR File dictionary definition language (DDL). This chapter describes the concepts and specification of the STAR File DDL dictionaries used to define the data items for core crystallographic, powder diffraction, modulated-structures and electron-density applications. For these applications, it discusses the purpose of data dictionaries, the structure of a DDL dictionary file, the function of DDL attributes and the specification of DDL attributes. Keywords: DDL1 specification; dictionary definition language; dictionaries; data definitions

In this paper a methodology is presented for the simulation and modeling of high speed interconnection links. To model a link, the link is divided into a number of sublinks and for each sublink a measurement based model is derived. Once a model for each sublink is available all models are connected together and a model for the complete link is obtained. Verification of the method is done by comparing simulation results with measurement results.
