Innovative virtualization technology IRF on WANs
Traditional WANs uses links and devices in 1+1 redundancy for availability, which enhances network reliability but results in low link and device utilization and increased management and maintenance complexity. To meet the virtualization requirements for the future cloud computing network, H3C deploys the IRF technology on WAN devices. The IRF technology virtualizes multiple physical devices into an IRF fabric, greatly reducing network management and maintenance costs, increasing link bandwidth and device utilization. With the IRF technology, the CR16000-F routers provide the following benefits:
Uses the multi-chassis link aggregation technology to implement load balancing and backup for multiple uplinks. This improves network reliability and increases link resources efficiency.
Virtualizes multiple CR16000-F routers into an IRF fabric to provide unified control plane and forwarding plane. This simplifies network topology, improves management efficiency, and reduces maintenance costs.
Uses the H3C-proprietary routing stateful failover technology to perform real-time data backup on the control plane and data plane in the entire virtualization architecture. This avoids service interruption caused by a single point of failure.
Powerful BRAS functions
Traditional service routers provide telecommunications services such as mobile, business, and IPTV services. BRAS devices act as access gateways to broadband network applications, and implement user authentication and management. The CR16000-F combines the service router and BRAS functions to improve the device usage and reduces costs.
Intelligent target accounting (iTA)—Differentiates service types based on the destination addresses and provides accounting, bandwidth control, and QoS as per the service types.
Provides unified access authentication for large numbers of wired and wireless users and meets requirements of wireless terminals for mobility and once-for-all authentication.
BRAS IRF stateful failover—Avoid service interruption caused by a single point of failure and simplifies management and maintenance.
Industry-leading network operating system
The CR16000-F router control plane uses the multi-core and SMP technologies, and runs the Comware V7 platform. Each software module operates with an independent address space, and supports dynamic loading and separate upgrading.
The Comware V7 platform supports distributed computing. Global services, such as MPLS and BGP, can be assigned to the specified MPU CPU system. The distribution of global services to different MPU CPU systems reduces CPU load and enhances system performance. Distributed computing also allows the system to divide a global service into sub-services and distribute the sub-services on different CPU systems.
The CR16000-F router uses Open Application Architecture (OAA) and provides Open Application Platform (OAP) modules to meet service customization and upgrade needs. For example, firewall modules, intrusion prevention system (IPS) modules, and LB modules provide seamless integration of core routers and service systems.
High Performance and Reliability
CR16000-F router support 800Gbps forwarding performance for each slot, providing high-density 10GE / 40GE / 100GE ports.
CR16000-F routers provide all key components redundancy, including control board, independent switching fabric, power supply, fan, etc.
CR16000-F routers support provide abundant reliability features to assure the network available even if link or node failure, such as BFD, LAG, NQA, ECMP, FRR, and so on.
