MPLS Migration to SD WAN

Frustrated over Expensive, Rigid, and Capacity-Constrained MPLS Networks? 

Epsilon SD WAN enables you to boost usable capacity, optimise WAN performance and improve resiliency at a lower cost per megabit. SD WAN can co-exist with MPLS or completely replace it with Ethernet or cost-effective Broadband Internet with comparable Quality of Service but with reduced cost and complexity.

Improve UCaaS Performance

Facing Poor Video and Voice Call Quality?

Epsilon SD WAN recognises and marks UCaaS traffic and steers it optimally and dynamically across the network, minimising jitter and packet loss to an optimised voice and video user experience.

Improve Network and Application Performance

Lacking the Visibility and Intelligence Needed to Easily and Quickly Identify Problems?

With more employees using more bandwidth-heavy applications, networks are experiencing more congestion,  packet loss and network outages. SD WAN provides you with a bird’s-eye view so you can identify network problems and act on them quickly. This allows you to plan capacity and prioritise your applications, thereby improving the user experience.

Enable Hybrid Workforce

Your VPN Can’t Scale to Support the Growing Mobile Workforce? 

Epsilon SD WAN improves application performance and provides direct cloud connectivity to simplify hybrid and multi-cloud initiatives. Flexible network security protects users, devices, and applications no matter if they are connecting from on-site or home.

Secure Internet Access

Getting Unpredictable Internet Performance? Time Consuming and Costly, as Every Branch Offices Needs to Deploy Security Appliances?  

SD WAN simplifies branch office operations and efficiently connects your branch offices to the internet. This makes establishing local breakouts easy. In addition, it simplifies branch office operations by delivering security as a cloud service and using software-defined policies to route traffic.

Enable Cloud-first Strategy

Current WAN Cannot Effectively Support the increase in Cloud-Applications? 

Traditional WANs were designed for applications hosted in a central data centre. With enterprises moving to the cloud, the need to backhaul cloud-destined traffic to the data centre increases latency and degrades application performance. Epsilon SD WAN addresses these challenges by transporting data directly from branch offices to the cloud. This also eliminates the potential for wasted bandwidth, increased latency and performance bottlenecks for cloud and web traffics.

Frequently Asked Questions

1. What is managed SD WAN?

Software-Defined Wide Area Network (SD WAN) is a virtual WAN technology that enables enterprises to leverage on any combination of network transport services such as Multi-Protocol Label Switching (MPLS), long-term evolution (LTE) and broadband internet services. It securely extends enterprise networks over large geographical distances and connects remote users to applications, services, and resources regardless of location.

2. How does SD WAN work?

With a centralised control pane, SD WAN enables network administrators to control and manage any configuration or deployment easily. Rules and policies can be set and deployed across an entire network at once, enabling traffic to be steered securely and intelligently across the WAN and directly to trusted SaaS and IaaS providers. This enhances WAN performance, improves WAN availability and agility, simplifies WAN management, and reduces WAN costs.

3. Is SD WAN and SDN the same ?

Both SD WAN and Software-Defined Networking (SDN) stem from the same central concept of controlling a network using software but have key differentiating factors.

SD WAN is a cost-effective alternative to traditional networking technology such as MPLS and focuses on supporting geographically distributed locations to deliver a WAN that connects multiple sites with each other. In some ways, SD WAN can be viewed as Software-Defined Networking (SDN) for the WAN.

SDN serves modern networking needs of managing Local Area Networks (LAN), and is inward focused on forming networks that can be quickly changed according to the organisations’ needs.

4. Why pick SD WAN over MPLS?

SD WAN is a new approach to WAN that is better than MPLS in many ways. Compared to MPLS, SD WAN may be more cost-effective and secure, while providing higher performance.


While MPLS handles failure scenarios with backup links, SD WAN handles them with real-time traffic steering based on centralised policy. In addition, SD WAN unifies the entire WAN backbone and delivers comprehensive analytics across the network globally. Given the disparate pieces of infrastructure and policies, these features are not possible with MPLS.

5. Does SD WAN replace MPLS?

While SD WAN can serve as a MPLS replacement, it is not an either-or choice. Both SD WAN and MPLS can be adopted as a hybrid architecture to maximise the benefits of both technologies.

MPLS provides a direct, secure connection which remains desirable for organisations seeking a high degree of integrity and privacy for their mission-critical data, applications, and transactions.

SD WAN, which offers granular traffic control, integrated security, and the ability to leverage multiple connection strategies, can still be run over an MPLS connection to provide greater protection and functionality than an MPLS solution alone.

6. Is SD WAN the same as VPN?

Both SD WAN and Virtual Private Network (VPN) are internet-based network solutions which enable enterprises to leverage on cost effective public Internet bandwidth.

In terms of network architecture, SD WAN act as gateways to a fully connected network of SD WAN appliances and allows for traffic to be restricted based on based on a user profile or traffic type, while VPN only implements point-to-point connectivity.

Both technologies also differ in transport media. SD WAN enables optimized, secure traffic routing over a variety of WAN connections such as the internet, LTE, 4G, or MPLS to various clouds for a seamless user experience and greater flexibility. Meanwhile, VPNs are designed to send all traffic over a single, secure network link.
