Features The MA5200F-2000 is
an intelligent broadband access server, and meanwhile
a high performance router. With its high-speed
switching technology, large-capacity switching
network and modular design, the MA5200F-2000 is
a high reliability, multi-service and scalable
access device with diversified interfaces, which
can well satisfy the demands of the carriers.
The following lists the features of the MA5200F-2000.
Powerful Route Forwarding Function
The MA5200F-2000 is based on the advanced architecture
of the fifth-generation routers, adopting the
advanced network processors and large scale ASIC
chips, thus it has excellent routing and transfer
capabilities.
The MA5200F-2000 can work as a standard router,
supporting a variety of routing protocols, including
the static route, Routing Information Protocol
(RIP) V1/V2, Open Shortest Path First (OSPF),
Border Gateway Protocol (BGP), PIM-Dense Mode
(PIM-DM), PIM-Sparse Mode (PIM-SM), and Internet
Group Management Protocol (IGMP) V1/V2, as well
as the tunneling protocols like L2TP and GRE.
The MA5200F-2000 has a built-in 10Gbps switching
fabric to support 4.4Gbps bidirectional linear
throughput at the ports, and linear packet forwarding
at 3Mpps. Based on its fifth-generation router
architecture, the MA5200F-2000 can ensure its
packet forwarding capacity after implementation
of the various service control policies such as
the access control list (ACL) and logs.
Larger Capacity and High Integration
The built-in 10Gbps large capacity switching
fabric ensures good forwarding performance and
Quality of Service (QoS). The MA5200F-2000 supports
2000 online subscribers of various types, 128
Virtual Local Area Network (VLAN) dedicated lines
and 128 transparent transmission VLAN dedicated
lines.
The ASIC chips enable high integration of packet
forwarding, data exchange, route processing, subscriber
management, security management and device management
on the MA5200F-2000.
Flexible Network Interfaces
The MA5200F-2000 provides 100M electric Ethernet
port, 100M optical Ethernet port, 100M multi-mode
optical Ethernet port, 1000M single-mode optical
Ethernet port and 1000M multi-mode optical Ethernet
port for different networks. It also provides
serial port and network port for maintenance.
Diversified Access Modes
Ethernet, xDSL, HFC and WLAN subscribers can
access through the layer2 devices like LAN Switch,
IP DSLAM (Digital Subscriber Line Access Multiplexer),
VDSL switch, CMTS (Cable Modem Terminal System)
and AP (Access Point).
Layer3 subscribers can access through Layer3
LAN Switch or router to the MA5200F-2000.
According to different access methods and access
requests, the MA5200F-2000 supports Layer2 individual
subscriber, Layer3 individual subscriber and dedicated
line subscribers (including Layer2 VLAN dedicated
line, Layer3 VLAN dedicated line, Proxy dedicated
line, VLAN transparent transmission dedicated
line and PPPoE dedicated line)
The access requests from a subscriber can be
touched off by various factors on the MA5200F-2000,
including Static configuration, DHCP packet, ARP
packet (ARP stands for Address Resolution Protocol),
PPPoE packet (PPPoE stands for Point-to-Point
Protocol over Ethernet), EAPoL packet (EAPoL stands
for Extensible Authentication Protocol over LAN)
and data packet. In this way, the subscribers
can obtain the service very conveniently when
they are in different status.
Flexible Authentication Methods
The MA5200F-2000 supports a variety of authentication
methods for your option: PPPoE authentication,
Web authentication, binding authentication, fast
authentication, 802.1X authentication, and no
authentication.
The MA5200F-2000 supports local PAP, CHAP and
EAP-MD5 authentication methods (PAP stands for
Password Authentication Protocol, CHAP stands
for Challenge Handshake Authentication Protocol).
It also supports remote PAP, CHAP, EAP-MD5 and
EAP-SIM authentication (EAP-SIM stands for EAP
Subscriber Identity Module).
The MA5200F-2000 can convert EAP-MD5 into CHAP,
so that the authentication servers that do not
support EAP-MD5 can provide 802.1X authentication.
Effective IP Address Solution
The MA5200F-2000 supports static IP address
and dynamic IP address, it provides built-in DHCP
server (DHCP stands for Dynamic Host Configuration
Protocol), and supports DHCP Relay of an external
DHCP server.
The MA5200F-2000 provides a unique function
of secondary allocation of IP address to protect
public IP address resource. It also provides Network
Address Translation (NAT) to enable effective
and flexible use of IP address resource.
Completed Accounting Scheme
The MA5200F-2000 can collect the accounting
information of the subscriber including time and
traffic. The MA5200F-2000 also supports local
and remote accounting.
Real-time accounting is supported both locally
and remotely, in order to ensure the accuracy
of the accounting information. Local protection
mechanism is provided in remote accounting, so
that the tickets will not get lost when the network
fails, and no error ticket will be generated.
The MA5200F-2000 supports different accounting
modes, including no accounting, prepaid accounting
and postpaid accounting. The prepaid accounting
can be on the basis of time or traffic. Together
with the RADIUS server (RADIUS stands for Remote
Authentication Dial in User Service), the MA5200F-2000
also supports the integrated prepaid accounting
based on time and traffic, and supports switching
between different tariffs.
Enriched Service Control Policies
The MA5200F-2000 provides access restriction,
traffic control, idle disconnection, QoS, policy
routing to guarantee the service quality.
Powerful Network Security Management
The MA5200F-2000 provides Access Control List
(ACL), user log, and forgery check to ensure legal
use and effective management of the network resources.
* Diversified Value-added Services
The MA5200F-2000 provides VPN, multicast, plug-and-play,
WLAN, forced Portal and IP Hotel to satisfy broadband
application in different scenarios, and bring
more revenue to the carriers.
High Security and Reliability
The powerful heat dissipation and temperature
adjustment system of the MA5200F-2000 enables
the operation of the device in places without
air-conditioners. The MA5200F-2000 provides both
-48V DC and 220V AC power module. Good electromagnetic
screen of the system enables its anti-interference
performance. The high-integration chip in the
network processor reduces the complexity of the
system, reduces the power consumption, and enhances
system stability. The system supports various
online loop tests and self-tests, and provides
abundant alarm information. Carrier-class isolation,
lightning proof and anti-interference design on
the subscriber ports ensure high reliability of
the devices on the subscriber side.
Good Maintainability
MA5200F-2000 supports local, remote and centralized
maintenance, through serial port communication
or Telnet connection on the Ethernet port. The
MA5200F-2000 supports Simple Network Management
Protocol (SNMP), using the iManager? N2000 centralized
management system of Huawei to provide complete
functions including alarm reporting, network test,
fault diagnosis and tracing.
Through HUAWEI Group Management Protocol (HGMP),
the MA5200F-2000 can manage and maintain the LAN
Switches and IP DSLAM devices in the lower layer,
and make the integrated global management easier
and more pleasant.
