TEM, DIA and MPLS buyer's guide
Why this guide matters
In today's interconnected world, reliable and secure enterprise connectivity is no longer a luxury, it's a necessity. The right combination of Traffic Engineering Management (TEM), Dedicated Internet Access (DIA), and Multi-Protocol Label Switching (MPLS) can be the difference between seamless operations and costly disruptions. Choosing the optimal solution requires careful consideration of your organization's unique needs, security requirements, and budget constraints. This guide will provide you with the knowledge and tools to make informed decisions and ensure a successful network transformation.
What to look for
Evaluating TEM, DIA, and MPLS solutions involves assessing several key factors. First, consider your organization's bandwidth requirements and application performance needs. Do you need guaranteed bandwidth for critical applications? Next, evaluate the provider's security capabilities and their ability to protect your data. Look for providers with robust firewalls, intrusion detection systems, and compliance certifications. Finally, assess the provider's service level agreements (SLAs) and their commitment to uptime and performance. A comprehensive evaluation will help you identify the solution that best meets your needs.
Evaluation checklist
- Critical Bandwidth Guarantees
- Critical Network Redundancy
- Critical Security Certifications (SOC 2, HIPAA, PCI DSS)
- Critical Service Level Agreements (SLAs)
- Important Geographic Coverage
- Important SD-WAN Integration
- Important AI-Powered Automation
- Nice-to-have Customer Support
- Nice-to-have Real-Time Monitoring
Red flags to watch for
- Lack of bandwidth guarantees
- Weak security posture
- Poor service level agreements
- Limited geographic coverage
- Inability to integrate with SD-WAN
- Lack of transparency in pricing
From contract to go-live
Implementing TEM, DIA, and MPLS solutions involves a structured, multi-phase approach. The initial phase focuses on discovery and planning, where you define your requirements and map your existing network. The next phase involves design and architecture, where network engineers build the "blueprints" for the new network. A pilot and proof of concept phase follows, allowing you to test the solution in a real-world environment. Finally, the full deployment and migration phase involves rolling out the hardware and circuits across multiple locations.

The true cost of ownership
The headline price of a network circuit is rarely the total price an organization pays. Understanding the hidden costs is essential for accurate budgeting. The local loop, the physical connection from the office to the service provider's network, can represent a significant portion of the total monthly cost. Early termination fees (ETFs) for long-term MPLS contracts can also be substantial. Security bolt-ons, such as next-generation firewalls (NGFWs), are often required for DIA and SD-WAN.
Compliance considerations for TEM, DIA, and MPLS
Enterprises must ensure their network infrastructure complies with relevant industry regulations and data privacy laws. For healthcare organizations, HIPAA compliance is critical to protect patient data. Financial institutions must adhere to PCI DSS standards to secure credit card information. GDPR compliance is essential for organizations operating in Europe. Choosing a provider with relevant compliance certifications can simplify the process and reduce risk. A robust security posture, including encryption and access controls, is also essential for maintaining compliance.
Your first 90 days
The first 90 days after go-live are critical for ensuring a successful implementation and maximizing ROI. Focus on achieving early wins, such as smoother video calls and faster file transfers, to secure user adoption. Provide comprehensive training to IT teams on new software-defined paradigms. Monitor network performance closely and address any issues proactively. Establish clear communication channels for user feedback and support. A well-planned and executed post-implementation strategy will set you up for long-term success.

Measuring success
Measuring success after deployment is the only way to validate the original business case. Success metrics should be tracked in a tiered fashion, from initial "Day 1" technical stability to long-term "Quarter 1" financial impact. Track key performance indicators (KPIs) related to network performance, security, and cost savings. Regularly review these metrics to identify areas for improvement and optimize your network configuration.
