Question: Do the interface cards, fan modules, and power modules of the AR series routers support hot swapping? If support, what are the benefits?
Answer: The Quidway? AR46 series routers are designed to meet the standards of the carrier-class. All the power modules, interface cards, and fan modules used in the routers of this series support hot swapping. This allows users to replace the cards and modules without disrupting services, thus delivering high equipment reliability suited for carrier-class network applications.

Question: Do the AR46 series routers support dual redundant power modules and how do they provide redundancy protection?
Answer: The power supply system of the Quidway? AR46 series routers consist of two power modules. Normally the two power modules (AC or DC) function in redundant backup mode, also known as load sharing mode. When one source of power breaks down or one power module fails, the other power module is intact and can supply the required power to the system. If you do not need redundant power supply, install only one power module.

Question: How efficiently can the AR46 series routers forward packets?
Answer: The IP packet forwarding efficiency is a key index for measuring the performance of a router. When forwarding a packet in a normal procedure, the router needs to determine the best route by searching the routing table according to the network information of the packet, and then forward the packet. Then, every packet that follows is forwarded and processed in the same way.
In addition to flexible service and protocol processing capabilities, the Quidway? AR46 series router provides an advanced fast route lookup algorithm for fast packet forwarding, thus, improving the forwarding and service processing capabilities of the system, with a forwarding capability of higher than 350 Kbps. In addition to delivering fast forwarding on a variety of high-speed link interfaces, such as Ethernet, synchronous PPP, FR, and HDLC interfaces, the router can forward packets quickly when combined with QoS and firewall capabilities.

Question: What are the QoS features that the AR46 series router supports?
Answer: The Quidway? AR46 series routers are designed and engineered to build QoS features into integrated services, such as real-time services, which supports Diff-Serv. The QoS features include traffic classification, policing, shaping, queue management, and scheduling to completely support six groups of PHBs and services as defined in standards, such as EF, AF1–AF4, and BE. These features enable network operators to offer different QoS levels for different users, making the Internet an integrated network that delivers data, voice, and video services.

Question: What is the difference between Committed Access Rate (CAR) and Line Rate (LR)?
Answer: The CAR works to limit the rates of only incoming and outgoing IP packets.
The LR can be applied to all the packets running through a physical port, but can only limit the rate of outgoing data.

Question: What are the NMS platforms that the AR46 series router supports?
Answer: Built on Huawei iManager N2000, the Quidway? AR46 series routers support the SNMP (V1/V2c/V3) protocol and client/server structure. These routers can independently run in either UNIX (SUN and HP) or ORACLE/SYBASE environments.
