 H3C S7600 Series Routing Switches product line includes the S7602, S7603, S7606, S7606-V, S7610, S7602-S, S7603-S, S7606-S eight major models, able to adapt to the different size of the network port density and performance requirements for operators Commercial building multi-service bearer metropolitan area network to provide the equipment protection. S7600 series routing switches, with H3C series router, Ethernet switch and iMC network management system provides a full range of solutions for operators and Metro Ethernet networking. 

 ? Complete the second floor features 

 High-capacity MAC table; 4K VLAN support, flexible QinQ capacity; spanning tree features full support; port trunking / port mirroring / broadcast storm suppression. The two-story properties to ensure that the equipment in the aggregation layer to meet the user's functional requirements. 

 ? Powerful three-tier 

 Large capacity three entries; complete routing protocol support; large-capacity multicast support. Large capacity forwarding items provide, S7600, to support large-scale MAN core convergence layer application, and to provide adequate support of the table of two, three, and MPLS applications. 

 ? MPLS Features 

 EoMPLS / MPLS L3 VPN / H-VPLS; VLL / VPLS / VRF; MPLS TE FRR; MPLS OAM. The MPLS technical support, S7600 MAN for operators to provide reliable multi-service based on MPLS-high security isolation, and provide a flexible, highly reliable virtual leased line and private network services for business users. 

 ? Rich QoS, ACLs features 

 S7600 to provide enhanced VLANs ACL, the egress ACL ACL feature, provides a wealth of resources for secure access management and control 

 In QoS, S7600 perfect Diff-Serv/QoS support. Support for priority marking or rate limit based on the packet flow classification results support two-way dual-speed tri-color and single-speed two-color bandwidth of the regulatory functions of support WRED and tail drop congestion control, support for the SP, WRR, WFQ queue scheduling algorithm support 802.1P, DSCP, EXP priority mapping and re-mark, and support based on port / port queue output stream shaping, and provides three levels of users, business and port-based priority queue scheduling capabilities for the Metro hosted network voice, data, video, and corporate private network and other business service quality assurance to provide an effective guarantee 

 Powerful QoS capabilities, S7600 MAN operators to provide a distinction between the quality of service on different types of business assurance, and provide finer bandwidth control based on the business for a number of personal and business users. 

 ? High reliability 

 In terms of hardware design, S7600 uses a passive backplane design, the full range of devices can be configured with two engine, single board to support dual-master switchover. Power systems with 1 +1 redundancy design, support for dual power input, and support for online fault detection, load balancing, hot-plug, alarm indication, all boards and fan box hot-swappable 

 In the second floor features, S7600 supports STP / RSTP / MSTP protocol, of VRRP v2/v3 protocols, and provides unique to the RRPP network protection agreement, ring network convergence time is about 50ms, effectively guarantee the application of the ring network is fast fault detection and protection, in addition, S7600 support SmartLink dual uplink standby link protection mechanism, cross-board aggregation function, Ethernet OAM is more simple, highly reliable, fault finding and means of protection. 

 In the three-layer routing protocol level, the S7600, to support Graceful the Restart for OSPF / BGP / ISIS and to ensure uninterrupted interface board in standby switching forwarding, to ensure the correctness of the network protocol status and service bearer network failure occurs. 

 Highly reliable design of the hardware and software, S7600 for the MAN of the operators to provide highly reliable hosted a variety of business, to ensure that the business failure recovery time to meet the 50ms carrier-grade requirements. 

 ? High security 

 The S7600 package security filtering / ACL mechanism to prevent the illegal invasion and malicious packet attacks. Routing protocols (OSPF, IS-IS, RIP-2, BGP, etc.) offers a variety of authentication methods (clear-text authentication, MD5, HMAC-MD5), and anti-DOS attack through the DHCP Relay security and DHCP Snooping security security features such as address counterfeit and can effectively prevent the binding of IP, MAC, Port, provides a complete security solution for the metro network construction. 

 Security mechanism can be obtained from the control, management, forwarding the security of of triplane comprehensive safety net. 

 ? Can be scalable 

 NP framework to support the future of rich business expansion; large-capacity backplane, with the ability to support higher performance board; form of the full range of equipment, covering MAN various locations. 

 Can be extended through the high hardware and software design, and S7600, to provide the processing performance for the MAN of the operators, the expansion of business characteristics, ability to meet the emerging needs of the business under the premise that fully protect users investment. 

 S7600 routing switch:
