Master-Level Computer Network Questions and Solutions

To illustrate the expertise provided by our service, here are two master-level questions along with their comprehensive solutions.

Question 1: Analyzing and Optimizing Network Performance

Problem Statement:

Given a network topology consisting of four routers (R1, R2, R3, R4) connected in a mesh configuration with varying link bandwidths and latencies, perform the following tasks:

1. Analyze the current network performance using the Dijkstra algorithm to find the shortest path from R1 to R4.

2. Propose optimizations to improve the overall network performance, considering load balancing and redundancy.

Solution:

Step 1: Analyzing Current Network Performance

Let's assume the following link details:

• R1 to R2: Bandwidth = 10 Mbps, Latency = 2 ms

• R1 to R3: Bandwidth = 15 Mbps, Latency = 1 ms

• R2 to R3: Bandwidth = 5 Mbps, Latency = 2 ms

• R2 to R4: Bandwidth = 10 Mbps, Latency = 3 ms

• R3 to R4: Bandwidth = 20 Mbps, Latency = 1 ms

Using Dijkstra's algorithm to find the shortest path from R1 to R4, we consider the latencies:

1. Initialize distances:

   • R1: 0 ms

   • R2: ∞

   • R3: ∞

   • R4: ∞

2. Update distances from R1:

   • R2: 2 ms (R1 -> R2)

   • R3: 1 ms (R1 -> R3)

3. Choose the next closest router (R3), and update distances:

   • R4: 2 ms (R1 -> R3 -> R4)

4. Finally, update distances from R2:

   • R3: No change (current path R1 -> R3 is already shorter)

   • R4: No change (current path R1 -> R3 -> R4 is already shorter)

The shortest path from R1 to R4 is R1 -> R3 -> R4 with a total latency of 2 ms.

Step 2: Proposing Optimizations

To optimize the network performance:

1. Load Balancing: Distribute traffic evenly across multiple paths to avoid congestion.

   • Implement Equal-Cost Multi-Path (ECMP) routing to utilize both R1 -> R3 -> R4 and R1 -> R2 -> R4 paths.

2. Redundancy: Ensure network reliability by having backup paths.

   • Add an additional link between R1 and R4 with a bandwidth of 25 Mbps and a latency of 1 ms.

3. Quality of Service (QoS): Prioritize critical traffic to ensure performance.

   • Implement QoS policies to prioritize latency-sensitive applications.

By implementing these optimizations, the network can achieve better performance, reliability, and efficiency.

Question 2: Securing a Wireless Network

Problem Statement:

Design a secure wireless network for a small business with the following requirements:

1. Ensure strong authentication for employees and guests.

2. Provide network segmentation to separate guest and employee traffic.

3. Implement measures to protect against common wireless attacks.

Solution:

Step 1: Strong Authentication

1. Employee Network:

   • Use WPA3-Enterprise with 802.1X authentication.

   • Integrate with the company’s Active Directory for user authentication.

2. Guest Network:

   • Use WPA3-Personal with a strong pre-shared key (PSK).

   • Implement a captive portal for guest access, requiring registration and agreeing to terms of use.

Step 2: Network Segmentation

1. VLANs:

   • Create separate VLANs for employee and guest networks.

   • Assign unique SSIDs for each VLAN (e.g., Company_Employee, Company_Guest).

2. Firewall Rules:

   • Implement firewall rules to restrict traffic between VLANs.

   • Allow guest VLAN access only to the internet, blocking access to internal resources.

Step 3: Protection Against Wireless Attacks

1. Rogue Access Point Detection:

   • Use wireless intrusion detection systems (WIDS) to detect unauthorized access points.

2. Mitigating Man-in-the-Middle (MitM) Attacks:

   • Enable HTTPS for all web-based communications.

   • Use VPNs for sensitive data transmission.

3. Preventing Denial-of-Service (DoS) Attacks:

   • Implement rate limiting and monitoring to detect unusual traffic patterns.

By implementing these measures, the small business can ensure a secure and efficient wireless network, protecting both employee and guest data.
