The forwarding capacity can be expanded smoothly from 40Gbit/s to400Gbit/s, and provides 100G line cards, allowing the CX600 to satisfy the increaseddemand for bandwidth for the near future. In addition, the CX600 is based on theVersatile Routing Platform (VRP) and is compatible with all line cards currently in CX600 reduces investment requirements to a minimum by making full use of existingcomponents. The design of the device is compact and interface density is ed IPTV FunctionsThe CX600 has a built-in video caching function, providing users with a smooth IPTVexperience. Based on fast channel change (FCC), retransmission request (RET) andinline Real-time Stream Monitoring, the CX600 can improve the user experience,optimize the OAM, save bandwidth resources and reduce the total cost of ownership(TCO) over the entire ed Metro Ethernet FeaturesBased on the mature Versatile Routing Platform (VRP), the CX600 excels inreliability, expansibility, and maintainability. The CX600 is an ideal platform for operatorsto build up carrier-class MANs. It supports various features including Hierarchical VirtualPrivate LAN Service (HVPLS), Virtual Leased Line (VLL), Layer 2 VPN (L2VPN), Layer 3VPN (L3VPN), multicast VPN, 802.1Q-in-802.1Q (QinQ), Virtual Local Area Network(VLAN) mapping, Dynamic Host Configuration Protocol (DHCP) server/replay/snooping,Protocol Independent Multicast-Source Specific Multicast (PIM-SSM), Internet GroupMembership Protocol Version 3 (IGMPv3), and MAC+IP+VLAN user binding. On thecarrier-class MANs based on the CX600, operators can provide Internet broadband
access services, Internet Protocol Television (IPTV) services, family multi-play services,IP leased line services, enterprise interconnection services, and enterprise VPN addition, the CX600 supports comprehensive clock synchronization solution,which well satisfies the requirements for carrier-class FMC service development in -Oriented IPv6-Compatible SolutionsThe CX600 supports a variety of IPv6 features including IPv6 lease line, NAT, dualstack, tunneling, and translation. The CX600 supports Next Hop Separation to optimizethe IPv6 convergence time and larger IPv6 FIB to improve the scalability. All of them helpto provide comprehensive solutions based on the high performance for transition fromIPv4 to IPv6. And owing to the variety of technologies and different situations of providernetworks, each provider will certainly select a conservative, reposeful, or aggressivetransition technology that is the most suitable for its own -designed QoS MechanismThe CX600 provides high-quality QoS by using multiple service traffic classificationmethods and identification policies to flexibly differentiate services and thus to ensure fairscheduling. 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 TrafficEngineering (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, andPseudo Wire Emulation Edge to Edge (PWE3), which ensures end-to-end QoSdeployment and proper configurations and efficient usage of network resources.• Hardware-based QoS which ensures line-rate forwarding after QoS services ed User Management FunctionThe CX600 provides Multi Service Edge (MSE) features to manage and controlDHCP/IP over Ethernet (IPoE)/leased line access users. The MSE mainly providesdynamic user access, user management, and user-based authentication, accounting,and QoS scheduling. In addition, the MSE implements Bandwidth on Demand (BoD) fordifferent services of enterprise users and for DHCP individual users and changes the
unified charging mode to the charging mode based on value-added services, whichimplements user centered refined service r-Class ReliabilityBased on the carrier-class design, the CX600 supports redundancy backup and hotswapping for all key components including SRUs, SFUs, power supply modules, fanmodules, management buses, Monitor buses, and data buses. The CX600 also supportsport binding, Virtual Router Redundancy Protocol (VRRP), and Rapid Ring ProtectionProtocol (RRPP) to ensure continuous service forwarding in the case of link faults. Withgraceful restart (GR), fast convergence, and key technologies such as BidirectionalForwarding Detection (BFD), IP Fast Reroute (FRR), Label Distribution Protocol (LDP)FRR, TE FRR, VPN FRR, VLL FRR, the CX600 ensures that services are convergedwithin 50 ms when abnormalities occur, thus ensuring continuous services. In addition,the CX600 supports MPLS OAM, Ethernet OAM, Y.1731, PWE3, and backup protectionof service routers. With the preceding features, the CX600 can achieve millisecond-levelprotection switchover of end-to-end ive Security FeaturesThe CX600 can help operators monitor the network status and protect users againstnetwork attacks. The CX600 supports Address Resolution Protocol (ARP) attack defenseand BGP session attack defense, and can flexibly control IP packets as required.
