1 Product Overview
The RSR20-X-28 series routers are data communication products independently developed by Ruijie Networks Co. Ltd.
by using advanced semiconductor technologies and communication control technologies. Ruijie series routers are
developed in full compliance with international standards, therefore, it is similar to major routers in terms of use and
configuration approach. Network administrators who are familiar with the configuration commands of major routers may
use the routers without receiving training first.
1.1 About the RG-RSR20-X-28
Developed from Ruijie’s RSR (Reliable multi-Services Router), RSR20-X-28, as the next generation access router, is
characterized by its applicability in a variety of access scenarios, such as routing, switching, security, 3G/4G and WiFi.
With improvements in performance, port number, rate and reliability, RSR20-X-28 offers integrated solutions for
enterprise edge networks at minimum costs. The Router provides a consolidated service infrastructure that enables
scalable deployment of new applications to better address the diversified demands for future business development.
RSR20-X-28 is an ideal choice for branch offices of medium and large-sized financial institutions, governments or
enterprises to access multiple services in a cost-efficient way.
Adopting advanced RGOS operation system, RSR20-X-
28 supports Ruijie’s patented technologies REF (Ruijie
Express Forwarding), VCPU (virtual CPU) and X-Flow. All these leading technologies guarantee stable forwarding
even when multiple services are enabled on the Router. Because of Stateful Firewall, RSR20-X-28 is good at resisting
flow attacks. The Router delivers plentiful backup solutions, QoS/HQoS characteristics, service-rich features, including
MPLS, VPN, multicast, IPv6, VoIP, NAT and MVRF. In this manner, users do not need to purchase additional software
Licenses or service modules.
Supporting HSIC service modules, RSR20-X-28 totally delivers up to 10Gbps bandwidth. The Router also supports
expansion of 10G Ethernet interface modules and other WAN and LAN modules of diverse types, multiple functions
and high intensity. Such expandability serves as a foundation for more combination possibilities. Plugging and
unplugging of hot-swappable HSIC service modules have no influence on forwarding services of other operating
modules. Plus, RSR20-X-28 supports alternating/direct current power supply redundancy, which helps enhance
reliability.
Aimed at offering users simplistic and efficient network, RSR20-X-28 supports simplistic network solutions, including
device virtualization, WAN port aggregation, IDA and ITO.
Different SIC slots support different extension service modules to flexibly meet users
’ requirements.
