Conclusion: Design Best Practices
The solutions in these new network designs all adhere to a common set of design principles:
First, every design is secured, both from an informational security perspective and from a reliability perspective.
Second, they combine the functions of the distribution and core tiers into a single tier where possible.
And finally, they simplify the network architecture to the base elements, thus reducing management, CAPEX, and OPEX.
For any enterprise design, nothing beats homework. Today, networks are complex arrangements that cannot be left to chance. Each design must be researched, assembled, proven, and then implemented. This cycle never ends; as one design is implemented, another is in the research stage. That’s because technology is moving at such a fast pace; if a network is left to its own devices, it will be obsolete in a very short time.
All of our network redesigns used Juniper Networks EX switches, MX edge routers, and SRX Services Gateways. Juniper has created design guides for most enterprise installations; see http://www.juniper.net/techpubs.
