Characterizing Network Traffic for Optimal Network Design
Characterizing Network Traffic
Characterizing Traffic Flow
Characterizing traffic flow is the process of identifying sources and destinations of network traffic and analyzing the direction and symmetry of data traveling between sources and destinations.
- Flow can be bidirectional and symmetric. (Both ends of the flow send traffic at about the same rate.)
- In other applications, the flow can be bidirectional and asymmetric.
- Client stations send small queries and servers send large streams of data.

Understanding Computer Networks: From ISPs to IP Routing
Class 1: Introduction to Internet Service Providers (ISPs) and Network Technologies
Autonomous Systems (AS) and Internet Exchange Points (IXPs)
Each ISP consists of one or more Autonomous Systems (AS). An AS is a group of routers under the control of a single ISP. Each AS is assigned a unique AS Number (ASN) by the Internet Assigned Numbers Authority (IANA). ISPs can connect their networks through Internet Exchange Points (IXPs), which are physical locations where networks can exchange traffic.

Intelligent Agents
An agent is anything that can be viewed as perceiving its environment through sensors and acting upon that environment through actuators.
Examples of Agents:
- Human agent: Eyes, ears, and other organs for sensors; hands, legs, mouth, and other body parts for actuators.
- Robotic agent: Cameras and infrared range finders for sensors; various motors for actuators.
- Software agent: Receives keystrokes, file contents, and network packets as sensory inputs and acts on the environment by displaying

(check for services running)
b. Open Ports
nmap -T5 scanme.nmap.org
(port status, port number, protocol type)
c. Active Hosts
$ ip a
$ nmap -sP 192.168.120.132/24

An Introduction to Bayesian Belief Networks
For an introduction to Bayesian belief networks, see Darwiche [Dar10] and Heckerman [Hec96]. For a thorough presentation of probabilistic networks, see Pearl [Pea88] and Koller and Friedman [KF09].
Learning Belief Network Structure
Solutions for learning the belief network structure from training data given observable variables are proposed in Cooper and Herskovits [CH92]; Buntine [Bun94]; and Heckerman, Geiger, and Chickering [HGC95].

Relational Database Design: Concepts and Best Practices
1. Informal Design Guidelines for Relational Schema Design
Informal design guidelines for relational schema design help ensure that the database is efficient, flexible, and easy to manage. Here are some key guidelines:
- Simplicity: Aim for a schema that is easy to understand and maintain. Avoid excessive complexity in the design, as it can lead to difficulties in query formulation and data management.
- Naming Conventions: Use meaningful and consistent
