Paper For Above instruction

In designing a Wide Area Network (WAN) that interconnects the three remote offices located in Los Angeles, New York City, and Chicago, selecting an appropriate switched network technology is essential to ensure reliable, scalable, and efficient connectivity. Given the requirements and the need to leverage switched network technologies, our proposal advocates for implementing a Multiprotocol Label Switching (MPLS) network, which offers multiple advantages over traditional switching methods such as VLAN or circuit switching in this context.

Proposed Switched Network: MPLS

Multiprotocol Label Switching (MPLS) is a highly versatile switching technology that directs data from one node to the next based on short path labels rather than long network addresses, enabling efficient and flexible traffic management. MPLS operates across an IP backbone and allows the creation of Virtual Private Networks (VPNs), which secure corporate traffic over a shared infrastructure. This technology is suitable for connecting geographically dispersed offices because it provides high performance, Quality of Service (QoS) capabilities, and scalability.

Implementing an MPLS-based WAN allows for the seamless routing of traffic between the three offices. MPLS's ability to prioritize critical traffic—such as VoIP or real-time data—makes it ideal for corporate environments. Additionally, service providers typically manage and optimize MPLS networks, thus relieving the organization from the complexities of infrastructure management while ensuring high availability and redundancy.

Traffic Flow and Network Architecture

In our proposed architecture, each office—Los Angeles, New York City, and Chicago—has its LAN connected to an MPLS router. These routers establish VPNs across the MPLS backbone, ensuring secure communication channels. Within each LAN, standard Ethernet or switched LAN technology connects devices, while the routers serve as gateways to the MPLS cloud.

The traffic flow between the offices involves data packets moving from a source LAN, through its local router, across the MPLS backbone, which tags the packets with labels for efficient routing. Depending on the priority and policy, MPLS can direct traffic through preferred paths, avoiding congestion. For example, a file transfer from Los Angeles to New York would originate at the Los Angeles LAN, pass through its local switch, reach the local router, then be encapsulated and labeled as it travels through the MPLS network. On reaching the New York Office's MPLS router, the data is de-encapsulated and sent to the local LAN switch for delivery to the recipient device.

Diagram of Network Architecture

While a visual diagram cannot be directly rendered here, the architecture involves three LANs, each connected via an MPLS router to a central MPLS service provider network. Each site’s LAN connects to its router, which interfaces with the MPLS cloud. The MPLS backbone routes traffic efficiently between these routers, maintaining VPNs and QoS policies. Each office maintains local switches connected to the routers, providing a secure and segmented LAN environment.

Benefits of MPLS for this Implementation

• Efficiency: MPLS forwards packets based on short labels, resulting in faster packet switching and less processing overhead.
• Scalability: Easy to add or remove sites by establishing new VPNs without disrupting existing traffic.
• Quality of Service: Supports multiple service classes, ensuring priority handling for mission-critical applications.
• Security: Provides VPN capabilities, isolating corporate traffic from other MPLS users.
• Reliability: MPLS networks offer redundancy and fast rerouting capabilities.

Conclusion

Choosing MPLS as the switched network technology for connecting the Los Angeles, New York City, and Chicago offices offers a combination of high performance, security, and scalability ideal for corporate WAN environments. Through this architecture, traffic between offices will flow efficiently, securely, and with high Quality of Service, meeting the organization's current and future connectivity needs. This solution aligns with industry best practices and leverages advanced switching technologies to deliver a robust network infrastructure supporting the company's operational goals.
