Building agility through a flexible, secure network infrastructure
A new approach to help meet your networking needs at a lower cost
The pace of technological advancement is increasing exponentially. Technology is providing options for people to learn more and perform faster. At the core of this acceleration are key advances in how organizations compute, communicate, process, and store information. For companies that require highly secure connectivity, the traditional approach has been to build a network with MPLS technology. Instead of traversing the public network, all traffic flows across a private network.
Latency-sensitive traffic like video and voice perform well in this environment due to traffic prioritization with class-of-service (CoS). And since the network doesn’t touch the public internet, security is inherent and not susceptible to distributed denial-of-service (DDoS) attacks. These benefits come with a higher price than networks built over the public network with IPsec encryption.
IPsec also provides a suitable network solution if your applications aren’t latency sensitive or don’t require the higher throughput speeds traditionally accomplished with MPLS. IPsec solutions typically have a lower cost because they send traffic over a broadband connection.
For example, retailers, clothing stores, and restaurants in a shopping mall can more cost-effectively transmit encrypted, low-bandwidth credit card transaction, inventory requests, and orders.
How companies deploy their network topology continues to change
Ten years ago, a typical enterprise may have had 30 critical sites, with critical IT workloads running at each. Recently, due to the desire to get closer to customers and vendors, that same organization looks very different, with perhaps 10 critical sites and an additional 60 small branches.
To accommodate this more flexible structure, this company has also moved its IT workloads to multiple cloud providers. This employs a hybrid approach that uses MPLS at the critical sites and IPsec over broadband at the smaller sites.
Fast forward to now and the immediate future
With the infusion of software-defined networking (SDN) and network function virtualization (NFV), universal CPE allows a new path to hybrid networking by deploying a dynamic hybrid approach.
This new option offers your enterprise more ways to construct your wide-area networks (WANs) to make them more agile, more flexible – and better able to meet current and future business networking needs at a lower cost with greater resilience.
