China Netcom three ER5200 Internet cafes enterprise dual WAN enterprise router
ER5200Yes H3C The company launched a high-performance Gigabit downlink router, which is mainly located in Ethernet /optical fiber / ADSL Access SMB Market and government, business organizations, Internet cafes and other network environments, such as the need for high-speed Internet Bandwidth, Internet cafes, businesses, schools and hotels.
ER5200The use of professional 64Bit dual-core network processor, clocked at up to 500MHz , And support a wealth of software features, such as IP <-> MAC Address binding, ARP Anti-attack, traffic rate limiting, dual WAN Load balancing, policy routing, source address routing, etc. It is H3C ER Series routers in the high-end products, large Internet cafe users and large enterprise users an ideal choice.

High processing performance
ER5200use 64Bit dual-core network processor, clocked at up to 500MHz , The processing capacity is equivalent to 1 GHz Of the professional network processor, at the same time DDRII high speed RAM For high-speed forwarding, can be achieved double WAN mouth 200MWire-speed forwarding in the practical application, the typical amount of tape machine300station.
double WAN Port load balancing
Load balancing can allow enterprise network users to allocate network traffic according to the actual bandwidth of the line to achieve the purpose of full use of bandwidth.China three communications with the domestic network user habits and characteristics of a targeted introduction of intelligent load balancing and manual load balancing of two Balanced mode to meet the dual-line access user bandwidth requirements for flexible applications.Intelligent load balancing according to the user's actual bandwidth than the actual allocation of network traffic; manual load balancing according to the import of the routing table to forward; support the strategy routing table import /Export function, just import the appropriate routing table can be achieved 'Telecom to take telecommunications, China Unicom to go Unicom ' Function.
ER5200Support standard IPSec VPN , The user can pass the simple WEB The configuration implements point-to-point security VPN Connection, the highest support 168Bit 3DES Encryption; H3C Combined with the characteristics of domestic users in the network ER5200On the same time through the domain name support configuration IPSec VPN Connect and NAT-T of NAT Through function.
ER5200Support multi-LAN capabilities, enterprises can easily partition the LAN for multiple network segments, reduce the broadcast domain and ARP The impact of the virus can be configured individually for each LAN DHCP Server And firewall rules, ER5200Up to simultaneous support 16Internal LAN.
ARP Virus dual protection
ER5200by IP <-> MAC Address binding function, a fixed gateway ARP List, can be effectively prevented ARP Deception caused by the interruption of network communications; ER5200Millisecond free of charge ARP Of the timing transmission mechanism, can effectively avoid the local area network PC Poisoning caused after ARP attack.
Network traffic rate limiting
BT , Thunder and so on P2P Software over-network bandwidth will affect the occupation of other users within the network of normal business, ER5200Based on IP Or based on NAT The network traffic rate limit mechanism of an entry can effectively control a single station PC On /Downstream traffic and established NAT The number of entries is limited P2P Software on the excessive use of network bandwidth.
Business controlQQ / MSN /Financial software)
QQ / MSN And other instant messaging software, a large number of popular, resulting in inefficient staff office, unable to concentrate. ER5200Unique application control functions, users can easily limit the network QQ / MSN Such as the use of applications, ER5200While supporting the great wisdom /Analysts /Flush /GF Xeon /Everbright Securities /State securities and other financial software application control functions.In addition, the user can set the privileged user group to ensure that the key user's use is not affected.
