Fiberhome CiTRANS 600 Series are new generation metropolitan optical transport network platform which are applied to packet transport network. The design is based on MPLS-TP architecture, uses PWE3 to emulate TDM services and Ethernet services via label-switching. CiTRANS 600 series inherit high-efficiency of SDH in maintenance with easy and friendly GUI (graphical User Interface) NMS (Network Management System), and in the meanwhile support end-to-end hierarchical QoS scheduling and high-precision clock synchronization for operators and subscribers.CiTRANS 600 series cover the entire network layers where switching capacity from 4.2Gbps to 12.8Tbps. CiTRANS 600 series are applied for Carrier Ethernet applica-tions including TDM/Ethernet leased-line services and L2VPN services, mobile backhaul services and etc. through a unified network architecture.
As a member of the CiTRANS 600 Metropolitan Optical Transport Network Platform,CiTRANS 615A is applied as mini access node which delivered 52Gbps (Unidirec-tional) of non-blocking forwarding with affluent TDM/Ethernet interface (10GE at maximum).
100% packet transmission architecture (IP Kernel) for all services.
Support PWE3 and Tunnel technology to realize Ethernet and traditional services including TDM.
Plug-and-play. Automatically allocation of IP address, manual software debugging procedure to increasing efficiency in services commissioning.
End-to-End QoS solution for SLA(Service-Level Agreement)
CiTRANS 600 series provides end-to-end QoS scheduling based on Diff-Serv model which can fully meet different requirements of different services on delay, jitter, and bandwidth. The implementation of traffic classification, marking, queue scheduling, congestion control and traffic shaping can realize the bandwidth control of user-level multi-service and guarantee time-delay-sensitive services with high priority forwarding which help the operator to providing value-add service with SLA.
Support both MPLS-TP and Ethernet OAM. CiTRANS 600 series platform support hardware based fast fault detection and location, performance monitoring, and end-to-end service management.
Provide carrier-class transmission function the protection switching time less than 50ms.
Unified Network Management provides SDH-like GUI operation.
With Advanced Traffic monitoring tools, users are able to expand network via hierarchy traffic statistics where the statistical report is based on actual traffic and alarm generated when threshold happen in both LSP and PW on UNI/NNI port. OAM performances detecting system model to build end-to-end OAM configuration, and it provides alarm-relevant to increase efficiency in fault localization.
Fiberhome CiTRANS 615A is the ideal solution as multi-service mini aggregation access platform particularly for enterprise leased line application which offers increased capacity at lower cost while providing the necessary service reliability and quality of experience that users expect and delivering a graceful evolution to packet network for future.
