Technical Overview


SD-WAN Overview

SD-WAN is an automated, programmatic approach to managing enterprise network connectivity and circuit costs. It extends software-defined networking (SDN) into an application that businesses can use to quickly create a smart WAN. The smart WAN comprises business-grade IP VPN, broadband Internet, and wireless services. Traffic is dynamically forwarded across the most appropriate and efficient WAN path based on network conditions, the security and QoS requirements of the application traffic, and cost of the circuit. You can set routing policies that determine how traffic is forwarded.

LTE Mini-Physical Interface Module Mini-PIM Overview

The LTE Mini-Physical Interface Module (Mini-PIM) provides wireless WAN support on the SRX320, SRX340, SRX345, SRX380 and SRX550M (High Memory) Services Gateways. The LTE Mini-PIM operates on both 3G and 4G networks. The Mini-Pim is available in two variations:

  • SRX-MP-LTE-AE, which is targeted for North America and the European Union

  • SRX-MP-LTE-AA, which is targeted for Asia and Australia

The main difference between the two variants is the LTE bands they operate on. You can configure LTE Mini-PIMs in three modes, Always-on, Dial-on-demand, and Backup. We’ve used Backup mode of operation in this NCE.
