USB Flash memory provides a choice of standby storage function. Comware software mirroring, configuration or other files can be replicated to USB Flash memory, and also then replicated to the router. As for reliability, it is compared to using CF (Compact Flash) card to save and recover files.

When it comes to supported file formats, USB Flash memory supports all the file formats supported on CF card (FAT16, FAT32). The configuration can be transferred from USB Flash memory to the router automatically for automatic configuration and deployment.

Huawei-3Com supports the following kinds of USB Flash memories: 64MB, 128MB, 256MB and 512MB. USB Flash memory provides a mechanism of backing up CF card. As USB Flash memory is widely used, you can fully enjoy high convenience and reliability generated by using USB Flash to backup and recover files.

II. USB application

With the introduction of USB interface, you can save the configuration of the router in USB Flash memory. After you insert the USB Flash memory holding the configuration in the USB interface, the router can get the configuration from the USB Flash memory and then upgrade and update automatically. In this way, you can realize “zero-touch configuration and implementation.” That is, enterprises and carriers can upload boot configuration into the USB Flash memory. With the help of boot configuration, a remote site can build a connection to the master site, and then download the complete configuration to carry out deployment.

By leveraging the mentioned USB features, enterprises and carriers can carry out deployment over a network without uploading the configuration to routers before delivery and deployment, so as to realize low touch or zero touch configuration and deployment. Furthermore, manufacturers can ship routers to customers directly without configuration. So the products can close the real requirements of customers for easy of use.

l POS interface.

2.6 Feature-riched Services

The next generation of MSR series routers provides a large number of services as follows:

I. xDSL

The next generation of MSR series routers has an optional SIC-ADSL2+ interface card. SIC-ADSL2+ offers common phone interfaces. By leveraging digital code modulation technology, you can access digital subscriber line access multiplexer (DSLAM) devices through the existing copper phone lines and obtain higher data transmission capacity.

With ATM adaptation layer 5 (AAL5) as the ATM adaptation layer protocol, the next generation of MSR series routers provides traffic services like constant bit rate (CBR), variable bit rate (VBR) and unspecified bit rate (UBR). Many issues, such as IP packet over ATM, authentication and accounting, are also solved through IPoA, PPPoA and PPPoEoA technologies. This series of routers is applicable to high speed data services and transmission of larger data packets and helpful for small- and medium-sized enterprises networks to access the Internet directly through broadband.

II. MPLS VPN and traditional VPN

The next generation of MSR series routers supports Layer 2 and Layer 3 tunneling protocols. Layer 2 tunneling protocol (L2TP) is helpful for users to enable dial-in virtual private data network (VPDN) and leased-line VPN services. Layer 3 tunneling protocol is enabled based on generic routing encapsulation (GRE) protocol. Combined with IPSec technology, it provides a full set of network security solutions for leased-line VPN, including access control, connectionless integrity and data source authentication, anti-replay, encryption and traffic classification and encryption. Both tunneling protocols can be used independently or jointly to provide better services.

MPLS is the combination of IP and ATM. It uses a short, fixed long label to replace IP header to identify data flows and as the basis of forwarding to provide higher forwarding rate. With the support of IP routing protocol and control protocol, MPLS can meet the network requirements of diverse new applications. In a MPLS network, tagged packets are transferred along the label switched path (LSP) made up of a series of label switch routers (LSRs). Using MPLS to enable VPN is of natural advantages because LSP itself is a tunnel on the public network. MPLS VPN refers to combine the geographical branches of a private network into a unified network. It supports the reuse of IP addresses between branches and interoperation between VPNs. MSR 20/30/50 series routers can function as not only label edge routers (LERs) but also label switch routers (LSRs). When MSR 20/30/50 series routers locate at the edge of a label domain, they as LERs can connect MPLS domains and non-MPLS domains as well as different MPLS domains, and classify services, distribute labels, encapsulate or strip off

Page 11: Table of Contents - GDC · of MSR series routers, combined with other series of Quidway routers and LAN Switches, can provide all-around and end-to-end network solutions for users

H3C MSR 50 Series Routers System Description Chapter 2 System Features

2-7

multi-tier labels. When the next generation of MSR series resides in a MPLS domain, it as LSR can exchange label packets.

III. DCC

The next generation of MSR series routers provides a perfect dial-in solution, with two dial-in modes supported: Circular DCC and Resourced-Shared DCC. In some cases, a connection is built and communication is carried out between routers only when there are messages need to transfer. So the transferred messages are time-free, small in volume and unexpected. DDC comes into being to offer a flexible and cost-effective solution for users. Especially, Resource-Shared DCC is rather perfect. It allows more than one dial-in user to share physical interfaces and make different calls through dialer pool. In real circumstances, DCC generally is used in backup mode to guarantee the master line communication. When the master line cannot communicate services for a line failure or other reasons, DCC provides a backup line to guarantee the operation of services. In addition, DCC can enable callback, including PPP callback, ISDN calling line identification callback.

IV. Voice

The next generation of MSR series routers provides mainstream voice communication protocols like H.323 and SIP for a variety of voice services such as emergency call/dial-in policy/fax/E-PHONE, and a variety of voice interfaces such as FXS/FXO/VE1/VT1/E&M.

By employing high performance digital signal process (DSP) chipset and high compression ratio coding/decoding algorithm, combined with the features from Comware V5 software platform like security, QoS and policy-based routing, the next generation of MSR series routers can ensure the transmission of voice over IP through silence compression, comfortable noise and anti-jitter measures.

Two connection modes are supported: quick connection and non-quick connection. The next generation of MSR series routers carries out out-band transmission of dual tone multi-frequency (DTMF) codes with tunneling while offering busy tone detection and some special services for PBX (for example, Do-Not-Disturb, transfer in busy and alarm clock).

Voice processing module (VPM) is also supported. It is a DSP array and easy of upgrading and expansion. All VE1 and VT1 interface cards share DSP resources of VPM, saving user investments and maximizing hardware resources.

The next generation of MSR series routers provides a rich of voice interfaces that can not only directly connect to general phones/faxes, but also connect to PBX switches through trunks like AT0 and E1/T1. It realizes interoperation with voice gateways from other vendors well in addition to high density and qualified voice and fax communications, 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 on ISDN PRI interface are supported. One-stage/dual-stage dial-in services are available.

H3C MSR 50 Series Routers System Description Chapter 2 System Features

2-8

Synchronous transmission of voice and data on PRI interface is also supported. As a result, the utilization is improved and the scope of supported services is enlarged.

The next generation of MSR series routers offers Gateway Keeper (GK) Client function that maintains communications with GK Server through Registration, Admission and Status (RAS) signaling. In this way, GK Server provides H3C voice gateway services like access permission, address translation, bandwidth management and voice gateway management. At the same time, it can network with mainstream voice gateway flexibly. This makes the next generation of MSR series routers fit for large- and medium- sized voice communications in enterprises.

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

The next generation of MSR series routers provides voice RADIUS function. When a voice call occurs, the router reports statistics including call duration, number of packets 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 table based on the network layer information of the packet to determine a best path for forwarding. And each subsequential packet will be processed by this process repeatedly. In addition to flexible services and protocol processing, the next generation of MSR series routers uses advanced quick route search algorithm to enable fast forwarding, improving forwarding and services processing capabilities significantly. The next generation of MSR series routers supports fast forwarding on a variety of high speed link interfaces. It can also forward packets rapidly in conjunction with QoS and firewall.

2.8 High Reliability

I. Hot-swappable power supply/interface card/fan

According to carrier-class product requirements, the next generation of MSR series routers is designed to support dual-power supply hot backup as well as hot-swappable power supplies/FIC interface cards/fan racks. Replacement is performed without affecting services so as to meet the high reliability requirements of carrier-class networks on devices.

II. Backup center and VRRP

With Backup Center and VRRP, the next generation of MSR series routers provides a backup solution in case of a communication line or device failure to guarantee smooth

Page 13: Table of Contents - GDC · of MSR series routers, combined with other series of Quidway routers and LAN Switches, can provide all-around and end-to-end network solutions for users

data communication, and thus boosting network robusticity and reliability effectively. Backup Center supports backup load balancing.

III. External storages like CF card and USB Flash memory

CF card and USB Flash memory can be used to store many system files and configuration 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 MSR series routers are developed based on Comware V5 platform. The QoS of V5 platform has inherited all the QoS features of previous Comware versions. That is, it supports Diff-Serv standard well. At the same time, it adds the supports of IPV6 QoS as well as MPLS Traffic Engineering (MPLS TE) and MPLS Resource Reservation Setup 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 users different levels of service guarantee, making the Internet a real data, voice and video integrated network.

The enablement of Differentiated Service (Diff-Serv) includes traffic classification, traffic policing (CAR), traffic shaping (GTS), congestion management (PQ/CQ/WFQ/CBQ) and congestion avoidance (WRED).

l Traffic classification: identify interesting objects by a certain matching rule. Traffic classification 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 of operators.

l Congestion management: measures you must take to settle resource competition in case of network congestion. Generally, it places packets in a queue for caching and 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 finds that the congestion is aggravating, it drops packets proactively and relieve network overload by adjusting traffic.

l Traffic shaping: a traffic control measure that actively adjusts the traffic output rate. Generally, it is used to adapt to the available network resources from the downstream 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 the designated path and reserve resources. So network traffic can bypass congested

nodes for the purpose of balancing. The next generation of MSR series routers can use QoS in a MPLS network flexibly. Furthermore, it can use original QoS of Diff-Serv for CE and PE routers and QoS of Int-Serv for MPLS aggregation/core networks to realize real end-to-end QoS guarantee.

2.10 Perfect Security Mechanism

The next generation of MSR series routers has many authentication methods (plain text authentication and MD5) and supports two kinds of user authorization modes: local authentication and RADIUS authentication. It can authenticate user IDs and authorization to prevent from illegal configuration of devices.

The ACL feature of the next generation of MSR series routers is used to create a combination 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 following cases where you can control access to the traffic on the user side or the network side and set the rights to access local information network or WAN by users for the purpose of protecting key servers, protecting system users, restricting foreign access, preventing from network attacks and supporting real-time updating.

The network address translation (NAT) feature of the next generation of MSR series routers allows for translation and recovery of IP addresses and ports. At the same time, it allows the Intranet to provide limited access to internal hosts by user configurations. The feature can also meet high capacity and high performance to adapt to the position of the next generation of MSR series routers in a network. In addition to above mentioned basic functions, the NAT feature of the next generation of MSR series routers limits the number of concurrent connections of individual users. As a result, it can reduce network strike from malicious resource occupation while meeting general network applications. You can output address translation information through logs to analysis network failures and locate hidden security troubles. The NAT feature provides application layer gateway (ALG) function for common specific application layer FTP and ICMP.

Furthermore, H3C MSR 50 series routers have plenty of statistics including traffic statistics, 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 route publication, 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 filters and applying these filters before receiving/publishing route information or exchanging route information 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

H3C MSR 50 Series Routers System Description Chapter 2 System Features

2-11

need to only receive or publish a part of route information meeting the specified conditions; when importing the route information of other routing protocols, the route protocol may need to only import a part of route information meeting the conditions, and set some attributes of the imported route information to satisfy the requirements of the protocol. Route policy provides a way to enable these functions for route protocols.

Route policies supported on the next generation of MSR 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 of great practical value to enhance the manageability of networks.
