Networking Blue Devils Justin Sdano David Strukel Dennis Murphy Sidney Fry Elizabeth Koering

Executive Summary Mary Kay is a jewelry store that is in the metropolitan New York area.  They carry a wide collection of engagement rings, wedding rings, diamonds, gemstones, watches, and metals.  May Kay is now implementing an e-business website to sell products over the internet. Networking Blue Devils plans on creating a network design that meets the needs of May Kay.  With the network designed by Networking Blue Devils, Mary Kay will have internet connection with security and high availability.

Problem Statement Mary Kay currently has a network with single connection to the local ISP.  The network has a switch that connects the perimeter router to the inside network and two web servers.   In four weeks, a link to a second ISP will be installed.  May Kay needs a new network design in two weeks to keep the project on time for the website kickoff.

Goals and Objectives A network design that provides an internet connection with security and high availability

Existing Network Analysis Network currently has switch, router and two web servers.  The switch is connected to the inside network.  The size of the inside network is unknown.

Needs & Constraints Business Technical E-Commerce Security Minimal network downtime Minimal customer impact during implementation Payment Card Industry (PCI) compliance Data Security Standard (DSS) compliance E-Commerce Security High Availability

Topology: Existing Network Problems: Single ISP connection to perimeter router Single switch connects the router to the inside network and two web servers

Medium branch office design Service Provider managed VPN Metro Ethernet Low cost for high speed internet Leased WAN Significantly cheaper and getting permits to run a new wire in NYC may be impossible Medium branch office design Service Provider managed VPN Significantly lower requirement for on-site IT staff at each location Proposed Network

Proposed Topology

Proposed IP Addressing Design Location Subnet Address Range Network Protocol ISP-A 10.0.0.0/30 10.0.0.1-10.0.0.2 ISP-B 10.0.0.4/30 10.0.0.5-10.0.0.6 Data Center to Store A 10.0.0.8/30 10.0.0.9-10.0.0.10 Data Center to Store B 10.0.0.12/30 10.0.0.13-10.0.0.14 Data Center to Store C 10.0.0.16/30 10.0.0.17-10.0.0.18 Data Center to Stare D 10.0.0.20/30 10.0.0.21-10.0.0.22 Store A to Store B 10.0.0.24/30 10.0.0.25-10.0.0.26 Store B to Store C 10.0.0.28/30 10.0.0.29-10.0.0.30 Store C to Store D 10.0.0.32/30 10.0.0.33-10.0.0.34 Store A to Store D 10.0.0.36/30 10.0.0.37-10.0.0.38 Data Center 10.0.1.0/24 10.0.1.1-10.0.1.254 OSPF Area 10 Store A 10.0.2.0/24 10.0.2.1 – 10.0.2.254 OSPF Area 20 Store B 10.0.3.0/24 10.0.3.1 – 10.0.3.254 OSPF Area 30 Store C 10.0.4.0/24 10.0.4.1 – 10.0.4.254 OSPF Area 40 Store D 10.0.5.0/24 10.0.5.1 – 10.0.5.254 Proposed IP Addressing Design

Protocol, Security, Performance & Availability Protocol: OSPF Security:  Cisco 4431 ISR has integrated security Protection against sophisticated threats Maintains performance Lower costs without need for separate security appliance Performance: 99.99% uptime Availability: Each ISP is connected to a separate router, which ensures the network will meet the goal for high availability. Redundant switches will also be placed in the data center to ensure high availability
