TCP provides multiplexing, demultiplexing, and error detection (but not recovery) in exactly the same manner as UDP Nevertheless, TCP and UDP differ in many ways The most fundamental difference is that UDP is connectionless, while TCP is connection-oriented UDP is connectionless because it sends data without ever establishing a connection TCP is connection-oriented because before one application process can begin to send data to another, the two processes must first "handshake" with each other -- that is, they must send some preliminary segments to each other to establish the parameters of the ensuing data transfer As part of the TCP connection establishment, both sides of the connection will initialize many TCP "state variables" (many of which will be discussed in this section and in Section 37) associated with the TCP connection The TCP "connection" is not an end-to-end TDM or FDM circuit as in a circuit-switched network Nor is it a virtual circuit (see 1), as the connection state resides entirely in the two end systems Because the TCP protocol runs only in the end systems and not in the intermediate network elements (routers and bridges), the intermediate network elements do not maintain TCP connection state In fact, the intermediate routers are completely oblivious to TCP connections; they see datagrams, not connections A TCP connection provides for full duplex data transfer That is, application-level data can be transferred in both directions between two hosts - if there is a TCP connection between process A on one host and process B on another host, then application-level data can flow from A to B at the same time as application-level data flows from B to A TCP connection is also always point-to-point, ie, between a single sender and a single receiver So called "multicasting" (see Section 48) -- the transfer of data from one sender to many receivers in a single send operation -- is not possible with TCP With TCP, two hosts are company and three are a crowd! Let us now take a look at how a TCP connection is established Suppose a process running in one host wants to initiate a connection with another process in another host Recall that the host that is initiating the connection is called the client host, while the other host is called the server host The client application process first informs the client TCP that it wants to establish a connection to a process in the server Recall from Section 26, a Java client program does this by issuing the command: Socket clientSocket = new Socket("hostname", "port number"); The TCP in the client then proceeds to establish a TCP connection with the TCP in the server We will discuss in some detail the connection establishment procedure at the end of this section For now it suffices to know that the client first sends a special TCP segment; the server responds with a second special TCP segment; and finally the client responds again with a third special segment The first two segments contain no "payload," i e, no application-layer data; the third of these segments may carry a payload Because three segments are sent between the two hosts, this connection establishment procedure is often referred to as a three-way handshake Once a TCP connection is established, the two application processes can send data to each other; because TCP is full-duplex they can send data at the same time Let us consider the sending of data from the client process to the server process The client process passes a stream of data through the socket (the door of the process), as described in Section 26 Once the data passes through the door, the data is now in the hands of TCP running in the client As shown in the Figure 35-1, TCP directs this data to the connection's send buffer, which is one of the buffers that is set aside during the initial three-way handshake From time to time, TCP will "grab" chunks of data from the send buffer The maximum amount of data that can be grabbed and placed in a segment is limited by the Maximum Segment Size (MSS) The MSS depends on the TCP implementation (determined by the operating system) and can often be configured; common values are 1,500 bytes, 536 bytes and 512 bytes (These segment sizes are often chosen in order to avoid IP fragmentation, which will be discussed in the next chapter) Note that the MSS is the maximum amount of application-level data in the segment, not the maximum size of the TCP segment including headers (This terminology is confusing, but we have to live with it, as it is well entrenched). itextsharp remove text from pdf c# How to replace specific word in pdf using itextsharp C# .net ...

The ability to open arbitrary connections to other servers is distressing for several reasons The first is that such a connection provides a channel for indirect attacks That is, a bad guy can cause your browser to run an attack against another server, making your machine take the blame Another is that information from your machine may be siphoned off to another site A third is that some attack code could be fetched from another location, leaving the true culprit applet in a less-suspicious situation should a successful attack be carried out against your machine Finally, and most realistically in terms of the example we will show later, the attack applet is able to download an image from any Web server, even those servers behind firewalls.
