Product Overview 

 SR8800 series routers of H3C launched based on a thorough investigation and a deep understanding of user business applications and Gigabit core routing products, mainly used in the IP backbone network, IP MAN and various large-scale IP network core and aggregation location. SR8800 series core router has a strong forward performance and service features to meet the needs of the user a variety of networking applications. 

 The SR8800 uses a plane separation and three engine-forward design concept, through hardware-based distributed high-performance network processor (NP) forwarding and high-capacity Crossbar non-blocking switching technology, to protect the system's high processing performance and flexible scalability; distributed QoS control unit for the bearer of core business to provide fine control and end-to-end service assurance; distributed OAM detection engine, the 30ms fault detection to protect the bearer service without disruption. SR8800 these innovative, high-reliability technology and fine QoS control mechanisms to ensure full multi-user business running smoothly. 

 Features 

 Innovative high-performance architecture to protect business 
 The SR8800 uses a four-plane separation of innovation and forward three engine architecture, the perfect fusion of Gigabit NP platform and Crossbar non-blocking switching technology to fully meet user requirements for business process performance and capacity. Plane separation architecture allows system management, monitoring and other functional modules to minimize the forwarding plane, forwarding plane are more focused on the processing of business, in order to achieve wire-speed forwarding of Gigabit traffic. Distributed Forwarding Engine interface board business processes to achieve hardware, SR8800 business interface board with NP business engine, QoS control engine and table search engine through a dedicated forward control engine so that the original table by NP business engine processing items to find and QoS scheduling and other functions all to the business processing board table search engine and QoS control engine, greatly accelerated the speed of business processes, completed Gigabit wire-speed processing of business at the same time, be able to achieve fine QoS scheduling mechanism and true sense of the E2E flow control. 

 Dedicated OAM engine guarantee the high reliability of the business 
 SR8800 in the traditional core router, dual-plane (control plane and forwarding plane) on the basis of the use of a dedicated OAM engine design with a unique OAM detection plane, the plane monitoring network failure, to achieve the fault detection 30ms and 20ms business switch to ensure that business operations are not interrupted. The detection plane and control plane, forwarding plane independent of each other, to provide users with a carrier-class reliability. 

 The SR8800 also supports improved equipment reliability mechanisms, including: key components 1 +1 redundancy, hot swap, hot patch function. 

 Built-in QoS engine to achieve the operational control of fine 
 Built-in QoS engine supports hierarchical QoS (H-QoS), multi-level scheduling mechanism based on port, user groups, users and user service H-QoS and MPLS TE can be achieved with the tunnel, according to business bandwidth reservation and scheduling. 

 QoS engine provides advanced queue scheduling (PQ, LLQ, CQ, WFQ, CBWFQ), congestion avoidance, traffic policing, traffic shaping, priority marking, guaranteed bandwidth, delay and jitter of different business, to meet different user different service levels differentiated services. " 

 QoS control engine provides the 200ms powerful package cache capacity to solve the problem of packet loss caused by the network burst traffic. 

 The SR8800 Crossbar switching support VOQ and E2E flow control technology, can effectively avoid the packet header blocking (HOL) and Crossbar on the message of "differentiated services".
