The CX600 supports Next Hop Separation to optimize the IPv6 convergence time and larger IPv6 FIB to improve the scalability. All of them help to provide comprehensive solutions based on the high performance for transition from IPv4 to IPv6. And owing to the variety of technologies and different situations of provider networks, each provider will certainly select a conservative, reposeful, or aggressive transition technology that is the most suitable for its own network.
Well-designed QoS Mechanism
The CX600 provides high-quality QoS by using multiple service traffi c classifi cation methods and identifi cation policies to fl exibly differentiate services and thus to ensure fair scheduling. The CX600 uses the following functions to ensure QoS:
Priority Queuing (PQ)
Weight Round Robin (WRR), and Weighted Fair Queuing (WFQ)
Flow-based scheduling, which facilitates the implementation of MPLS Traffic Engineering (TE).
Differentiated Service (DiffServ) and Integrated Service (InterServ) mechanisms, which combines the use of MPLS TE and the DiffServ model.
MPLS DS-TE capability with a maximum of eight class types (CTs).
Five-level Hierarchical QoS (HQoS) scheduling and QoS for MPLS VPN, VLL, and Pseudo Wire Emulation Edge to Edge (PWE3), which ensures end-to-end QoS deployment and proper confi gurations and effi cient usage of network resources.
Hardware-based QoS which ensures line-rate forwarding after QoS services are deployed.
Enhanced User Management Function
The CX600 provides Multi Service Edge (MSE) features to manage and control Point-to-Point Protocol over Ethernet (PPPoE)/IP over Ethernet (IPoE)/leased line access users. The MSE mainly provides user access, user management, and user-based authentication, accounting, and QoS scheduling. In addition, the MSE implements Bandwidth on Demand (BoD) for different services of enterprise users and individual users then changes the unifi ed charging mode to the charging mode based on value-added services, which implements user-centered refi ned service operation.
Industry Largest CGN Board
To achieve the IPv6 transition, the CX600 can provide the integrated CGN solution. The 80G and 160G CGN boards supported by CX600 are the industry largest capacity CGN boards. The large capacity CGN service board can also support maximum 64M session number and 2M/ s session establishing rate. Besides, it can support the popular IPv6 transition solutions such as NAT44, DS-Lite, L2NAT and NAT64, and so on. In addition, the CGN board can achieve cross- chassis hot standby, which guarantees the high availability for the CGN services.
Carrier-Class Reliability
Based on the carrier-class design, the CX600 supports redundancy backup and hot swapping for all key components including SRUs, SFUs, power supply modules, fan modules, management buses, Monitor buses, and data buses. The CX600 also supports port binding, Virtual Router Redundancy Protocol (VRRP), and Rapid Ring Protection Protocol (RRPP) to ensure continuous service forwarding in the case of link faults. With graceful restart (GR), fast convergence, and key technologies such as Bidirectional Forwarding Detection (BFD), IP Fast Reroute (FRR), Label Distribution Protocol (LDP) FRR, TE FRR, VPN FRR, VLL FRR, the CX600 ensures that services are converged within 50 ms when abnormalities occur, thus ensuring continuous services. In addition, the CX600 supports MPLS OAM, Ethernet OAM, Y.1731, PWE3, and backup protection of service routers. With the preceding features, the CX600 can achieve millisecond- level protection switchover of end-to-end services.For Mobile Backhaul networks, especially the future oriented LTE network, NE40E adopt advanced Hierarchical L3 solution, deploying HVPN the OAM more effective, and it can achieve E-to-E segment by segment fault demarcation and confi rm each IP base station status.
Cooperating with performance management tools such as U2000, NE40E can provide SDH like network OAM, service oriented, intelligent warning, and refi ned positioning. Besides, the ISP can monitor the network status in real time through the NMS. The ISP then check whether the forwarding capacity of the network complies with the Service Level Agreement (SLA) signed with users and locate faults. The ISP does not need to carry out detection on the user side, which greatly decreases maintenance costs.
Extensive Security Features
The CX600 can help operators monitor the network status and protect users against network attacks. The CX600 supports Address Resolution Protocol (ARP) attack defense and BGP session attack defense, and can fl exibly control IP packets as required. In addition, the CX600 supports Generalized TTL Security Mechanism (GTSM) of OSPF and BGP, VPLS and L3VPN traffi c statistics, DHCP snooping, lawful interception and IPSEC to build a secure and controllable network.

Conforming to ITU-T Y.1731, the CX600 supports performance management by inserting the timestamp into 802.1ag LB messages to measure the delay, jitter, and packet loss ratio when the messages are transmitted. In this manner, the CX600 can detect the end-to-end performance of traffi c in a specifi ed time period and on a specifi ed network segment.
For MPLS TP OAM, CX600 can support functions such as Basic connectivity detection, LoopBack(LB), Link Trace (LT), Remote Defect Indication (RDI), AIS, Single-ended frame loss statistics collection and two-ended frame loss statistics collection, detecting One-way frame delay and two-way frame delay, VE interfaces support TP OAM, Dynamic PWs and MS-PWs support TP OAM.
For Mobile Backhaul networks, especially the future oriented LTE network, CX600 adopt advanced Hierarchical L3 solution, deploying HVPN technology, which can guarantee effi ciency, security, and reliability. L3 to edge solution makes the OAM more effective, and it can achieve E-to-E segment by segment fault demarcation and confi rm each IP base station status.
Cooperating with performance management tools such as U2000, CX600 can provide SDH like network OAM, service oriented, intelligent warning, and refined positioning.With supporting effi cient and precise performance measurement and test technologies such as IP FPM, TWAMP, RFC2544, G.8032, NE40E can help to simplify the OAM and save the OPEX to a great extend. Besides, the ISP can monitor the network status in real time through the NMS. The ISP then check whether the forwarding capacity of the network complies with the Service Level Agreement (SLA) signed with users and locate faults.
