FiberHome CiTRANS R800 series are enhanced IP/MPLS router solution which combine the dynamic flexibility of routers, and the quick service deployment and high-efficient maintenance of SDH with easy and friendly GUI (graphical User Interface) NMS (Network Management System). In addition to affluent IP/MPLS features, R800 provide SDH-like OAM, end-to-end QOS solution and high-precision clock synchronization for operators or subscr- ibers. CiTRANS R800 series cover all the network layers, which support switching capacity from 8Gbps to 1.28Tbps.
CiTRANS R800 series are applied for Carrier Ethernet applications include business services, such as Layer 2 and Layer 3 VPN, IPTV, mobile backhaul transport networks, and broadband network gateway, etc , through a unified network architecture.
As a member of the CiTRANS R800 enhanced router solution, CiTRANS R860 can be deploy- ed as core node or aggregation node in Metropolitan Area Network(MAN).CiTRANS R860 is a high-capacity provider router that delivered320G (Unidirectional) of non-blocking forward- ing with affluent TDM/Ethernet interface (10GE at maximum) in a 21-rack-unit (21RU).
CiTRANS R860 supports unidirectional 320Gbps cross-connection capacity, and its space saving design can be installed in the 300mm depth cabinet
Average power consumption is 30% less than other vendor due to lower PC chip widely adopted
The intelligent fan unit providing excellent and flexible heat dissipation can simply conquer the challenges caused by harsh environment in both high and low temperature.
With distributed hardware forwarding and non-blocking switching technology, CiTRANS R860 supports L2/L3 access and forwarding for multi-type service
Support FE/GE/10GE Ethernet interface and cSTM-1 type TDM interface
Support L2VPN based on Martini protocol VPWS, VPLS
Support L3VPN based on MPLS/MBGP protocol: dynamically distribute VPN routes and VPN labels
Support PWE3 to simulate different media service
Provide perfect H-QoS mechanism(Including Traffic Classification,Traffic Policing, Queue scheduling, Congestion Avoidance, Traffic Shaping)
Support IP multicast service based on IGMP, PIM-SM/DM, Static multicast group, etc
Support dual-stack: IP / MPLS OAM and IETF MPLS-TP OAM
Support smooth evolution from IPV4 to IPV6
Support RIP, OSPF, IS-IS, BGP and static routing
Support Routing Policy (Route Mapping) and IP-Policy-based routing
Support TCP/IP protocol stack, including ICMP, IP, TCP, UDP, and ARP, etc
Support MPLS label forwarding, static LSP tunnel, LDP LSP, and RSVP-TE LSP also.
Support fast recovery by adopting LSP protection, IP FRR, TE FRR, PW Redundancy (for L2VPN), VPN FRR (for L3VPN), VRRP and etc., while single or multiple failures occurs.
Support single-hop or multiple-hop BFD (utilized OAM mechanism) for OSPF, ISIS, BGP, Tunnel, VPN FRR.
Support protocol-level GR (graceful restart) technology and device- level GR technology to provide uninterrupted NSF forwarding.
Protocol-level GR includes OSPF GR, ISIS GR, BGP GR, LDP GR and etc.
Service link failure recovery within 50ms, node failure recovery within 200ms,Service recovery without perception.

With flexible networking capability, perfect reliability design, great intelligence, and excellent service protection ability etc., CiTRANS R860 is an ideal choice for MAN aggregation node.
