The NE40E Series routers run on the Versatile Routing Platform operating system and use Huawei-developed NP chips and hardware-based forwarding and non-blocking switching technologies. Based on distributed hardware forwarding, non-blocking switching technologies, distributed Clos architecture. In general, are deployed at the access and convergence layers of the carrier-class MAN. Based on distributed hardware forwarding and non-blocking switching technologies, the CX600 features carrier-class reliability, line speed forwarding capability, a well-designed Quality of Service(QoS) mechanism, strong service-processing capability, and excellent expansibility. In addition to providing competitive Layer 2 services, including Ethernet access and convergence, Ethernet switching, and transmission of Ethernet over Multi-Protocol Label Switching (EoMPLS) services, the CX600 provides diverse Layer 3 (IP) services, such as Internet broadband services, triple play (video, voice, and data) services for individual users as well as IP leased line and IP Virtual Private Network (VPN) services for enterprise users. Based on enhanced video features including fast channel change (FCC), retransmission request (RET) and inline Real-time Stream Monitoring the CX600 can improve user experience in the IPTV service. The CX600 series includes the CX600-X16, CX600-X8, and CX600-X3, thus satisfying requirements for networks of various scales.
