The Accelerator 4800 Series is the most popular model of the Accelerator family. It increases WAN capacity, improves application response times, and offers extensive built-in Layer 7 QoS to prioritize network applications according to business objectives. The Accelerator 4800 allows data transfers in excess of the link speed by reducing latency and packet loss with standard TCP acceleration (based on SCPS) and Web-based application acceleration. It also delivers robust performance and fault management using SNMP, RMON/RMON II, and NetFlow.

The Accelerator 4800 Series can be deployed in mid-sized remote offices and central sites. It scales from 256 Kbps to 6 Mbps and provides rack-and-stack options. It can support mesh networks and is deployed either On-Path between the LAN segment and router or On-LAN by connecting it non-obtrusively to the switch or router. It includes fail-to-wire functionality, supports standard failover protocols and features a front-panel LCD and keypad for simplified installation and configuration.
