2.9 Superior QoS
The next generation of AR series routers are developed based on VRP5 platform. TheQoS of V5 platform has inherited all the QoS features of previous VRP versions. That is, itsupports Diff-Serv standard well. At the same time, it adds the supports of IPV6 QoS aswell as MPLS Traffic Engineering (MPLS TE) and MPLS Resource Reservation Protocol(MPLS RSVP).
QoS Diff-Serv model includes traffic classification, traffic policing, traffic shaping, queue
management and queue scheduling that completely enables six sets of PHB services (EF,AF1 to AF4, BE) defined in standards. This allows network operators to provide usersdifferent levels of service guarantee, making the Internet a real data, voice and videointegrated network.
The enablement of Differentiated Service (Diff-Serv) includes traffic classification, trafficpolicing (CAR), traffic shaping (GTS), congestion management (PQ/CQ/WFQ/CBQ) andcongestion avoidance (WRED).
l Traffic classification: identify interesting objects by a certain matching rule. Trafficclassification is the premise for differentiated services.
l Traffic policing: monitor the specifications of the specified traffic flowed into the
router. Once the traffic has exceeded the specifications, you can take restriction

or punishment measures to protect business interests and network resources ofoperators.
l Congestion management: measures you must take to settle resource competitionin case of network congestion. Generally, it places packets in a queue for cachingand uses a scheduling algorithm to determine the forwarding order.
l Congestion avoidance: too congestion may damage network resources.Congestion avoidance monitors the utilization of network resources. When it findsthat the congestion is aggravating, it drops packets proactively and relievenetwork overload by adjusting traffic.
l Traffic shaping: a traffic control measure that actively adjusts the traffic outputrate. Generally, it is used to adapt to the available network resources from thedownstream routers and avoid unnecessary packet drop and congestion.
MPLS traffic engineering (MPLS TE) is a QoS technology based on Int-serv module.By combining traffic engineering and MPLS, you can establish a LSP tunnel to thedesignated path and reserve resources. So network traffic can bypass congestednodes for the purpose of balancing. The next generation of AR series routers can useQoS in a MPLS network flexibly. Furthermore, it can use original QoS of Diff-Serv forCE and PE routers and QoS of Int-Serv for MPLS aggregation/core networks torealize real end-to-end QoS guarantee.

The ACL feature of the next generation of AR series routers is used to create acombination of rules that permit or deny based on source/destination IP address segments(including host address) or source/destination ports. This is applicable to the followingcases where you can control access to the traffic on the user side or the network side andset the rights to access local information network or WAN by users for the purpose ofprotecting key servers, protecting system users, restricting foreign access, preventing fromnetwork attacks and supporting real-time updating.
The network address translation (NAT) feature of the next generation of AR series routersallows for translation and recovery of IP addresses and ports. At the same time, it allowsthe Intranet to provide limited access to internal hosts by user configurations. The featurecan also meet high capacity and high performance to adapt to the position of the next
generation of AR series routers in a network. In addition to above mentioned basicfunctions, the NAT feature of the next generation of AR series routers limits the number ofconcurrent connections of individual users. As a result, it can reduce network strike frommalicious resource occupation while meeting general network applications. You can outputaddress translation information through logs to analysis network failures and locate hiddensecurity troubles. The NAT feature provides application layer gateway (ALG) function forcommon specific application layer FTP and ICMP.
Furthermore, Quidway AR 2921&41 routers have plenty of statistics including trafficstatistics, traffic sample and NAT information statistics.

2.11 Robust Route Policy
Route policy consists of a series of rules which are broken into three types used for routepublication, route receiving and route import respectively. Route policy is referred to as
route filter, because the definition of a policy is equivalent to the definition of a set of filtersand applying these filters before receiving/publishing route information or exchanging routeinformation between different protocols.
Route policy is used with routing protocols to strengthen the control of routing protocols.When exchanging route information with the peer, a upper layer routing protocol may needto only receive or publish a part of route information meeting the specified conditions; whenimporting the route information of other routing protocols, the route protocol may need toonly import a part of route information meeting the conditions, and set some attributes ofthe imported route information to satisfy the requirements of the protocol. Route policyprovides a way to enable these functions for route protocols.
Route policies supported on the next generation of AR series routers include route policy
definition, route import and distribution definition and restriction rules like route prefix,autonomous system path, community attribute and access list. The use of route policy is ofgreat practical value to enhance the manageability of networks.

GE Interface
AR 29-21 MPU has two 10/100/1000Mbps auto-sensing Ethernet electrical interfaces;AR 29-41 MPUs have two gigabit Combo interfaces respectively. Each interfacesupports two kinds of connectors: optical and electrical. Where electrical interface
uses RJ45 connector and optical interface uses Small Form-Factor Pluggable (SFP)module. You can select it as required.
AR 29-41 provide five kinds of 1000Base-FX SFP pluggable optical interface modules.You can select short haul multi mode (850nm), mid-haul single mode (1310nm), longhaul single mode (1310nm), long haul single mode (1550nm) and ultra long haulsingle mode (1550nm) optical modules if necessary. All optical modules come with LCinterface and are hot-swappable.
Here are the GE interface features:
