605.777.81 - Internetworking with TCP/IP II

Computer Science
Spring 2024

Description

This course builds on the foundation established in EN.605.677, Internetworking with TCP/ IP I. Changes are being made in the infrastructure, operation, and protocols of the Internet to provide the performance and services needed for real-time applications. This course first examines the current architecture and operation of the Internet. The classful addressing concept will be introduced and the mapping of Internet addresses to physical addresses is discussed along with the extensions that have been made to the addressing paradigm, including subnet addressing, classless addressing, and network address translation. The performance enhancements being developed to provide quality of service (QoS) over the Internet and to provide faster routing through the use of IP switching techniques are discussed. Techniques for providing multicasting and mobility over the Internet are examined. Security considerations are addressed by examining Virtual Private Networks and the use of IP Security (IPSec) protocols. The next generation IP protocol (IPv6) is introduced, and the changes and enhancements to the IP protocol operation and to the addressing architecture are discussed in detail. Finally, the development of the Voice Over IP (VoIP) application and the convergence of circuit switching and packet switching are discussed. Topics include subnet addressing, CIDR, DHCP, DNS, NAT, IntServ, DiffServ, RSVP, CIP, MPOA, IP Switching, Tag Switching, MPLS, IP Multicast, IGMP, Reliable Musticast, Multicast Routing Protocols, IP Mobility Home Agents and Foreign Agents, Message Tunneling, Proxy and Gratuitous ARP, VPN Tunneling, PPTP, L2F, L2TP and SOCKSv5, VPN security, IPSec, Encapsulating Security Payload header, Authentication Header, Security Association, IPv6 Addressing, IPv6 protocol and extension headers, Neighbor Discovery, IPv6 Stateless Address Autoconfiguration, DHCPv6, VoIP, H.323 Gateways and Gatekeeper, SIP, SDP, RTP, MGCP, Megaco/H.248.

Course Structure

A list of reading assignments from the textbook, class modules and the Internet are posted each week in the Canvas Course Contents area. A schedule of the weekly assignments and their due dates is provided to ensure that you progress through the materials in a timely fashion. You are responsible for keeping up with the class reading assignments. You will use Canvas for course communications and submission of assignments. A drop box in the assignment area will be used for submitting your homework assignments, exams, and term paper. Assignments must be submitted on time. You will be penalized for handing in assignments after the due date. Please keep up with your readings and visit the Canvas course interface regularly!

Participation in class discussions is a mandatory part of the course. You will be graded on your participation in the class discussion. Discussions will be held every other week for a period of 5 days. You are expected to take part in the discussion and make substantial contributions to the discussion on a minimum of three of the ve days in which the discussion takes place. You may use email to privately communicate with the instructor about anything pertaining to the course. You may also use the discussion area to ask questions or make comments of general interest to the class. Please check the homepage regularly for announcements pertinent to the course.

Course Goals

The objective of this course is to gain an understanding of the concepts and techniques that have been used to design and implement the TCP/IP Internet and to understand the issues that are driving the development of new protocols to broaden and enhance the operation of the Internet. The Internet is a collection of autonomous systems that make use of routing technology to transport datagrams between hosts using an unreliable, best-effort service. A connection-oriented transport protocol is implemented in the hosts to provide a reliable transport service on top of the unreliable datagram service. With the growth in the number of hosts and routers, and the development of new real-time applications such as Voice over IP (VoIP), the TCP/IP operational paradigm is no longer valid. Changes must be made in the infrastructure, operation, and protocols of the Internet to provide the performance and services needed for real-time applications.

Course Policies

All assignments must be handed in on time. There is a one-time one day grace period for a late assignment. You are allowed to use the one-day grace period one time without penalty. A 10% penalty will be assessed for subsequent late assignments. No assignment will be accepted outside the one-day grace period. You will receive a failing grade for that assignment.

Academic Policies

Deadlines for Adding, Dropping and Withdrawing from Courses

Students may add a course up to one week after the start of the term for that particular course. Students may drop courses according to the drop deadlines outlined in the EP academic calendar (https://ep.jhu.edu/student-services/academic-calendar/). Between the 6th week of the class and prior to the final withdrawal deadline, a student may withdraw from a course with a W on their academic record. A record of the course will remain on the academic record with a W appearing in the grade column to indicate that the student registered and withdrew from the course.

Academic Misconduct Policy

All students are required to read, know, and comply with the Johns Hopkins University Krieger School of Arts and Sciences (KSAS) / Whiting School of Engineering (WSE) Procedures for Handling Allegations of Misconduct by Full-Time and Part-Time Graduate Students.

This policy prohibits academic misconduct, including but not limited to the following: cheating or facilitating cheating; plagiarism; reuse of assignments; unauthorized collaboration; alteration of graded assignments; and unfair competition.

Classroom Climate

JHU is committed to creating a classroom environment that values the diversity of experiences and perspectives that all students bring. Everyone has the right to be treated with dignity and respect. Fostering an inclusive climate is important. Research and experience show that students who interact with peers who are different from themselves learn new things and experience tangible educational outcomes. At no time in this learning process should someone be singled out or treated unequally on the basis of any seen or unseen part of their identity. 
 
If you have concerns in this course about harassment, discrimination, or any unequal treatment, or if you seek accommodations or resources, please reach out to the course instructor directly. Reporting will never impact your course grade. You may also share concerns with your program chair, the Assistant Dean for Diversity and Inclusion, or the Office of Institutional Equity. In handling reports, people will protect your privacy as much as possible, but faculty and staff are required to officially report information for some cases (e.g. sexual harassment).

Course Auditing

When a student enrolls in an EP course with “audit” status, the student must reach an understanding with the instructor as to what is required to earn the “audit.” If the student does not meet those expectations, the instructor must notify the EP Registration Team [EP-Registration@exchange.johnshopkins.edu] in order for the student to be retroactively dropped or withdrawn from the course (depending on when the "audit" was requested and in accordance with EP registration deadlines). All lecture content will remain accessible to auditing students, but access to all other course material is left to the discretion of the instructor.
