The next generation of AR series routers provides mainstream voice communicationprotocols like H.323 and SIP for a variety of voice services such as emergencycall/dial-in policy/fax/E-PHONE, and a variety of voice interfaces such asFXS/FXO/VE1

By employing high performance digital signal process (DSP) chipset and highcompression ratio coding/decoding algorithm, combined with the features from VRPV5 software platform like security, QoS and policy-based routing, the next generationof AR series routers can ensure the transmission of voice over IP through silencecompression, comfortable noise and anti-jitter measures.

Two connection modes are supported: quick connection and non-quick connection.The next generation of AR series routers carries out out-band transmission of dual

tone multi-frequency (DTMF) codes with tunneling while offering busy tone detectionand some special services for PBX (for example, Do-Not-Disturb, transfer in busy andalarm clock).

Voice processing module (VPM) is also supported. It is a DSP array and easy ofupgrading and expansion. All VE1 interface cards share DSP resources of VPM,saving user investments and maximizing hardware resources.

The next generation of AR series routers provides a rich of voice interfaces that cannot only directly connect to general phones/faxes, but also connect to PBX switchesthrough trunks like AT0 and E1. It realizes interoperation with voice gateways fromother vendors well in addition to high density and qualified voice and faxcommunications, protecting the existing investments of users effectively. When E1

trunk is used to connect a PBX, R2 signaling as well as DSS1 and Q.SIG signaling onISDN PRI interface are supported. One-stage/dual-stage dial-in services are available.Synchronous transmission of voice and data on PRI interface is also supported. As aresult, the utilization is improved and the scope of supported services is enlarged.

The next generation of AR series routers offers Gateway Keeper (GK) Client functionthat maintains communications with GK Server through Registration, Admission andStatus (RAS) signaling. In this way, GK Server provides Quidway voice gatewayservices like access permission, address translation, bandwidth management andvoice gateway management. At the same time, it can network with mainstream voicegateway flexibly. This makes the next generation of AR series routers fit for large- andmedium- sized voice communications in enterprises.

By compressing redundant information like voice header on low-speed PPP seriallinks, IP Header Compression (IPHC) reduces the bandwidths used by voice channelssignificantly and maximizes network resources.

The next generation of AR series routers provides voice RADIUS function. When avoice call occurs, the router reports statistics including call duration, number ofpackets and number of bytes to RADIUS Server for accounting.

2.7 Powerful Forwarding/Service Processing

IP packet forwarding efficiency is a key index of performance measurement. When the

router forwards a packet according to general procedure, it needs to look up the routing


14/61


System Description


table based on the network layer information of the packet to determine a best path forforwarding. And each subsequential packet will be processed by this process repeatedly.In addition to flexible services and protocol processing, the next generation of AR seriesrouters uses advanced quick route search algorithm to enable fast forwarding, improvingforwarding and services processing capabilities significantly. The next generation of AR

series routers supports fast forwarding on a variety of high speed link interfaces. It can alsoforward packets rapidly in conjunction with QoS and firewall.

2.8 High Reliability

III. External storages like CF card and USB Flash memory

CF card and USB Flash memory can be used to store many system files andconfiguration to improve system reliability. External storages can accommodate a

large volume of system logs and security logs for backing up, browsing and archiving.

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


15/61


System Description


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.

2.10 Perfect Security Mechanism

The next generation of AR series routers has many authentication methods (plain textauthentication and MD5) and supports two kinds of user authorization modes: localauthentication and RADIUS authentication. it can authenticate user IDs and authorizationto prevent from illegal configuration of devices.

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.

System Description


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.

Quidway NE series high-end and core routers are used as P devices in theheadquarters. AR 49 series routers are also used as PE devices to access the servicenetworks of branches. With VPF technology, diverse services in branches are

partitioned into different VPN networks through PE devices, guaranteeing the securityand reliability of services.

AR 19/29 series routers are used in branches to connect to AR 49 series routers in theheadquarters. Different services are separated through physical networks in branches.When there are many services in a physical network, the VRF feature of AR 49 canrealize logical separation of service networks.

You can use different ways to build tunnels for MPLS VPN services. Using MPLS TEtunnel to carry VPN services is of great benefits in many aspects. As a result, VPNservices have superior security and reliable QoS guarantee. Additionally, carriers cancustomize MPLS TE tunnels with different features to meet VPN user requirements.

5.6 Network Application of Voice Services
