Juniper has created an implementation guide that will help network designers create a simplified Internet edge solution using Juniper Networks MX Series 3D Universal Edge Routers, SRX Series Secure Services Gateways, and EX Series Ethernet Switches. This guide details specific design considerations, best practices, and Juniper tools that can be used to build the optimal solution. It concludes with a real-world deployment example that illustrates the solution and recommended configurations in detail.
The Role of the Internet Edge
The Internet edge acts as the enterprise’s gateway to the Internet. It provides connectivity to the Internet for data center, campus, and branch offices, and it connects remote workers, customers, and partners to enterprise resources. It can also be used to provide backup connectivity to the WAN for branch offices, in case the primary connection to the enterprise WAN fails.
Today’ s Internet edge must enable access to a variety of applications such as cloud computing solutions, mission critical applications, and bandwidth hungry applications such as video. The Internet edge must also scale seamlessly to support growing application performance and bandwidth needs, while supporting a rich set of routing and security features. This guide will help you reach this goal.
Scope of the Guide
This Internet edge implementation guide discusses design concepts and articulates implementation details to help WAN architects and engineers deploy an Internet edge solution. Although the specific implementation will vary, the fundamental building blocks provided here can help accelerate any deployment.
The guide covers design considerations such as routing, security, resiliency, and quality of service (QoS) that must be addressed in designing an Internet edge deployment. It describes the factors driving the need for these considerations and provides a high-level background applicable to the solution described.
It also covers details the actual implementation of the Internet edge, starting with a high-level overview of the topology and business considerations, which is followed by a more detailed explanation of the three parts of the topology (border routers, security devices, and core and DMZ).
This guide is well suited for organizations that are:
• Designing robust, highly scalable, and resilient Internet edge infrastructure
• Simplifying management by consolidating devices and eliminating single purpose devices in the Internet edge
• Improving security within the Internet edge solution
This guide serves as a reference tool for the following audience:
• Network engineers
• Network architects
• Security managers
• System test engineers
The New Network Platform Architecture
In a previous blog I wrote about the New Network Platform Architecture and how Juniper is delivering network designs that will enable our customers to optimize their network investments. With these designs Juniper’s goal is to help customers overcome technology limitations so that they can deliver greater efficiency, and increased business value, by leveraging their networks more effectively.
As enterprises rely on the Internet edge to provide access to cloud computing applications, mission critical applications, and video feeds, they need a network that can seamlessly scale for increasing application performance and bandwidth needs, while at the same time supporting a rich set of routing and security features. The Juniper solution described in this guide is designed with these objectives in mind. It will enable customers to drastically reduce deployment time and minimize errors by using the steps and best practices described in this guide, as well as the architecture guidelines and validated configurations outlined in it.
