product description

ER3200Yes H3C The company introduced a high-performance router, which is mainly located in the Ethernet /optical fiber / ADSL Access to SMB Market and government, business organizations, Internet cafes and other network environment, such as the need for high-speed Internet Bandwidth of Internet cafes, businesses, schools and hotels.

ER3200Using professional 64Bit network processor, clocked up 500MHz , And supports rich software features such as IPSec VPN , Multi-LAN, IP <-> MAC Address binding, ARP Anti-attack, traffic speed limit, double WAN Load balancing, policy routing, source address routing, etc. It is H3C ER Series of routers in the end products, medium-sized Internet cafes users and business users the ideal choice.

product description

lHigh processing performance

ER3200 uses 64-bit network processor, clocked at up to 500MHz, at the same time with DDRII high-speed RAM for high-speed forwarding, can achieve 100M wire-speed forwarding.

lDual WAN port load balancing

Load balancing can let the enterprise network users allocate network traffic according to the actual bandwidth of the line to achieve the purpose of making full use of bandwidth.With the use of domestic network users and the characteristics of the use of targeted to introduce the intelligent load balancing and manual load balancing two balanced mode To meet the needs of the dual-line access to the user's flexible bandwidth application.Intelligent load balancing based on the actual bandwidth of the user to allocate the actual network traffic; manual load balancing according to the imported routing table for forwarding; support policy routing table import / export function, Just import the appropriate routing table can be achieved 'Netcom to take Netcom, Telecom to take the telecommunications' function.

lIPSec VPN

The ER3200 supports standard IPSec VPNs. Users can implement secure VPN connections between point-to-point through a simple WEB configuration. Up to 168-bit 3DES encryption is supported. At the same time, the H3C user interface is supported on the ER3200. IPSec VPN connection and NAT-T NAT traversal function.

lMulti-LAN function (VLAN)

ER3200 supports multi-LAN function, enterprises can easily divide the LAN for multiple network segments, reduce the impact of broadcast and ARP viruses, for each LAN can be configured with a separate DHCP Server and firewall rules, ER3200 can support up to 16 internal LAN The

lARP virus double protection

ER3200 through the IP <-> MAC address binding function, fixed the gateway ARP list, can effectively prevent ARP spoofing caused by interruption of network traffic; In addition ER3200 free ARP timing to send the mechanism, you can effectively avoid the board? Poisoning caused by ARP attacks.

lNetwork traffic rate limit

BT, Thunder and other P2P software on the excessive use of network bandwidth will affect the normal business of other users within the network, ER3200 based on IP or NAT-based entries in the network traffic rate limit mechanism can effectively control a single PC uplink / downlink traffic And the number of NAT entries established, limiting the P2P software on the excessive use of network bandwidth, flexible bandwidth and ensure the full use of bandwidth on the bandwidth.

lBusiness control (QQ / MSN / financial software)

QQ32 MSN and other instant messaging software, a large number of popular, resulting in inefficient staff office, can not focus on. ER3200 unique application control function, you can easily limit the network users on the use of QQ / MSN applications, ER3200 also support the large Wisdom / Analyst / Flush / Guangfa Xeon / Everbright Securities / Guoyuan Securities and other financial software application control function.In addition, the user can set the privileged user group to ensure that the use of key users is not affected.

Many Internet cafes friends are asking a question, why my Internet cafes are always dropped? Dropped by a variety of reasons, but one of the reasons can not be ignored is the lack of bandwidth, then why is the lack of bandwidth? First of all, the story of an ancient time, a family of three brothers, met the disaster year, the remaining food must be saved to eat to support the next year. Boss count, three people can only eat five meals a meal, did not expect, Youngest is a long body, meal to eat 5 two meals, this look, the other two brothers can only go hungry.

Similarly, Internet cafes inside BT, Thunder, streaming media on demand, the game ... ... these will take up a lot of bandwidth, as long as there are a few people in use, other users will not get bandwidth, naturally led to dropped. How to do it? We say back to the story of three brothers, the boss made a decision: the youngest to eat three meals a day, the other people eat one or two meals a day, are not allowed to eat other people, so that although the three brothers can not eat But it will be enough.

Internet cafes is actually taken in this way, the traditional QoS is the allocation of static bandwidth for different users, so that users will not affect each other. On the surface seems to solve the problem of Internet cafes, but the new problems of the three brothers In the opposite of the old bowl of rice, the two brothers need to solve a problem: points to eat or keep, because the boss said can not eat someone else's.

Perhaps we will feel that the problem is ridiculous, but not the same thing to eat, but the same problem into the Internet cafes this scene is not so simple.For traditional QoS, the solution is like to stay for the youngest, even if Youngest does not need, others starved to death can not eat this is bound to bring a huge waste of bandwidth.

Is there a new way to solve the problem of uneven brotherhood? H3C (Huawei Technologies) based on the new flexible QoS design ideas launched ER series routers completely solve this problem.

Assume that A and B are two IP addresses, each allocated 2M of bandwidth.When A, B now need more than 2M bandwidth, A, B can only use 2M bandwidth; if one of them is free, For example, B only need 1M bandwidth, then the remaining 1M bandwidth can be used by A. This is a good solution to the Internet because of insufficient bandwidth dropped the problem, that is, so that the three brothers have the possibility of eating.

Not only that, ER series routers combine flexible QoS with more applications and introduce a series of very useful QoS features. Let's take a look at the green channel feature.

According to statistics, in online cafes play online games accounted for 59% of the proportion, compared with other applications, online games with small packets, take the characteristics of less bandwidth.I believe that the Internet peak, many Internet cafes will encounter online games Very card situation, there is a great impact on the business, then there is no way to ensure that the network is busy when the network game is smooth?

In fact, Internet cafes encountered this problem in the supermarket also has a similar situation.Some customers only buy a few goods, the original checkout soon, but more people in the time, had to buy something a lot of customers So that the supermarket and the customer are reluctant to see.Therefore, many supermarkets provide fast access, specifically for those who buy less goods customers quickly checkout.

In the Internet cafes equipment applications, this method has also been transplanted over, some professional servers have been widely used. Similarly, ER series routers also provide a green dedicated channel function, you can for the message of smaller online games Not only that, in order to avoid wasted bandwidth, green dedicated channel also combines the design of flexible QoS to ensure the quality of the network at the same time, make full use of limited bandwidth.

Through the above description we can easily see, ER series of routers is tailored for the Internet cafes network equipment. Also for Internet cafes dropped, slow distress friends, your troubles left ER series routers. Believe me, That's right.
