Introduction: Congestion Control Transfer Protocol (CCTP) is an advanced, stable message-determined transport layer protocol. CCTP lies in between the Network layer and Application layer and serves as the agent between network operation and application programs. Figure below shows the IP suite associated with the relationship of CCTP protocol with others. This protocol blends the prominent characteristics of TCP, UDP and SCTP. APPLICATION LAYER NTP FTP HTTP DNS DHCP TRANSPORT LAYER CCTP TCP UDP NETWORK LAYER IP IGMP ICMP IGRP ARP DATA- LINK LAYER ATM ARP ETHERNET PHYSICAL LAYER USB BLUETOOTH ISDN FIELD LENGTHS: TCP CCTP DATA One entity in TCP segment Several data chunks in a packet HEADER 20 bytes 16 bytes CHECKSUM 16 bits 32 bits STREAM IDENTIFIER None Verification tag SEQUENCE NUMBER Identifies by using header TSN, SI, SSN A CCTP packet has a mandatory general header and a set of blocks called chunks which are classified in to data and control chunks. Source port address (16 bits) Destination port address (16 bits) Verification tag (32 bits) Checksum (32 bits) Common layout of a chunk Data that contains more than one message cannot be carried by a CCTP data chunk so that message should be made in to several chunks. At least one byte of data should be carried by the data field of the data chunk, which implies the value of lengt... ... middle of paper ... ... CCTP protocol, we allocate every individual packet with Transmission Sequence Number, Stream Identifier, Stream sequence number in order to achieve reliable data transfer. Because in the aspect of huge data transfer like 3D streaming, we cannot achieve reliability due to the availability of limited bandwidth channels (i.e,TCP). Every individual packet in CCTP is divided into several control chunks which has distinct values of ( TSN, SI, SSN). Improvements over Existing protocol: • UDP: Message-oriented, Unreliable. • TCP: Byte-oriented, Reliable. • CCTP: Message-oriented, Reliable. • Acknowledgement and validation techniques amplify the security by four way handshake in order to shield the data from over flooding. • Loss of the information in one proceeding will not affect the reception of next consecutive message, As it is not byte oriented protocol like TCP.
The method of communication over the FCIC II / CJ Net network is the same standard that has been used on the Internet, TCP/IP.
In regards to the perspective on human nature, CBT has a more complex view on this topic in comparison to other theories. CBT’s perspective incorporates the use of self-control, self-reflection, and the capacity of choice (Tan,2011). The use of self-control, self-reflection, and capacity of control are essential in creating change in behaviors and feelings. In addition, more attention is placed on how an individual’s thoughts can affect their feelings and behavior’s (Tan, 2011).
Lab 1 demonstrates the capabilities of congestion control algorithms implemented by Transmission Control Protocol (TCP). It provides three scenarios to simulate these algorithms and will later compare the results.
What does TCP mean? TCP is a set of rules that governs the delivery of data over the internet or other network that uses the Internet Protocol, and sets up a connection between the sending and receiving computers.
If the maximum packet lifetime is not large enough a duplicate packet could be sent while the ACK is still in the process of being transmitted back to the original sender. This could cause issues where there are duplicate packets being sent. Additionally, this will cause unnecessary congestion issues if there are extra packets and ACKs being sent.
Sliding windows, a strategy otherwise called windowing, is utilized by the Internet's Transmission Control Protocol (TCP) as a technique for controlling the stream of bundles between two PCs or system has. TCP requires that every single transmitted data be recognized by the getting host. Sliding windows is a technique by which numerous bundles of information can be insisted with a solitary affirmation.

For an in-depth defence approach, case study provides a series of things that describe about what is working nowadays for a secure data.
The goal of this paper is to define and explore the MD5 checksum utility. It is also my goal to discuss how to use MD5 checksums to support Incident Response.
TCP/IP is a network model which enables the communication across the Internet. The most fundamental protocol on which the Internet is built. This is made up of the 2 common networking protocols, TCP, for Transmission Control Protocol, and IP, for Internet Protocol. TCP maintains and handles packet flow linking the systems and IP protocol has the ability to handle the routing of packets. However The TCP/IP stack consists of 5 layers first being application layer, the transport layer, then the network layer, the link layer and finally the physical layer. The assignment focuses on the three middle layers and is divided into five parts. Firstly explaining how the TCP and UDP the most vital protocols needed to deliver and communicate.
Padding of length m is added to the message to overcome the message length issue.
TCP/IP operates at both levels 3 and 4 of the OSI model. The TCP portion of TCP/IP operates at level 3 (Network) as its primary function is to control the flow of data. IP operates at level 4 (Transport) of the OSI model. IP is the protocol responsible for the actual transmission of packet across the network.
In this era when the Internet provides essential communication between tens of millions of people and is being increasingly used as a tool for security becomes a tremendously important issue to deal with, So it is important to deal with it. There are many aspects to security and many applications, ranging from secure commerce and payments to private communications and protecting passwords. One essential aspect for secure communications is that of cryptography. But it is important to note that while cryptography is necessary for secure communications, it is not by itself sufficient. Cryptography is the science of writing in secret code and is an ancient art; In the old age people use to send encoded message which can be understand by the receiver only who know the symbolic and relative meaning of that encoded message .The first documented use of cryptography in writing dates back to circa 1900 B.C. Egyptian scribe used non-standard hieroglyphs in an inscription. After writing was invented cryptography appeared spontaneously with applications ranging from diplomatic missives to war-time battle plans. It is no surprise, then, that new forms of cryptography came soon after the widespread development of computer communications. In telecommunications and data cryptography is necessary when communicating in any untrusted medium, which includes any network, particularly the Internet [1].Within the context of any application-to-application communication, there are some security requirements, including:
IP telephony, unlike other Internet applications, is still dominated by concerns about interworking with older technology, here, the PSTN. Thus, we can define three classes [21] of IP telephony operation as shown in Fig. 1.1, depending on the number of IP and traditional telephone end systems.
TC or transactional communication has four key factors, simultaneous communication, multidimensional communication, time factor, and the noise factor. In the following essay, I will look at what the key factors are and give some examples of how they work in my life.
