Clients and server

This thesis proposes and implements a new and novel solution on simulators and real devices to solve the mobility problem in a VPN. The new solution adds mobility support to existing L2TP/IPsec (Layer 2 Tunneling Protocol/IP Security) tunnels. The new solution tunnels Layer 2 packets between VPN clients and a VPN server without using Mobile IP, without incurring tunnel-re-establishment at handoff, without losing packets during handoff, achieves better security than current mobility solutions for VPN, and supports fast handoff in IPv4 networks.

In this chapter we discuss our first client/server application program, Dynamic Host Configuration Protocol (DHCP). This application is discussed first because it is the first client/server application program that is used after a host is booted. In other words, it serves as a bootstrap when a host is booted and supposed to be connected to the Internet, but the host does not know its IP address.

This chapter is an introduction to the application layer. In the next eight chapters we introduce common client-server applications used in the Internet. In this chapter, we give a general picture of how a client-server program is designed and give some simple codes of their implementation. The area of network programming is a very vast and complicated one; it cannot be covered in one chapter. We need to give a bird’s-eye view of this discipline to make the contents of the next eight chapters easier to understand.

Client-Server Application Connection Oracle Net enables a network connection between a client and an Oracle database server. Oracle Net is a software component that resides on both the client and on the Oracle database server. It is layered on top of the network protocol. When a connection is initiated from a client to the Oracle database server, data is passed down a stack on the client, over the network, and up a similar stack to the Oracle database server.

As described in Section 2.5 of the textbook, the Domain Name System (DNS) translates hostnames to IP addresses, fulfilling a critical role in the Internet infrastructure. In this lab, we’ll take a closer look at the client side of DNS. Recall that the client’s role in the DNS is relatively simple – a client sends a query to its local DNS server, and receives a response back. As shown in Figures 2.21 and 2.22 in the textbook, much can go on “under the covers,” invisible to the DNS clients, as the hierarchical DNS servers communicate with each other to...

Chapter 17 provided a description of the protocols at the user’s disposal for configuring services on the Internet. We saw that the service configuration architecture assumes an XML document stored on a server. The client retrieves a copy of the XML document, makes changes to it, and sends the delta back to the server. In IMS, the architecture for service configuration architecture is developed around the XML Document Management (XDM) architecture created by the Open Mobile Alliance (OMA) in the XDM [244] set of specifications. ...

Introduction to the Oracle Server Technologies avoids these issues by formatting a report’s output as XML tags. Any client can request an XML Publisher report and (provided it has an XML parser) display the results. This is the key to distributing reports over wireless protocols to any device, such as a cellular telephone. Oracle Discoverer is an end-user tool for report generation. Oracle Reports and XML Publisher need a programmer to design the report.
