ER3200Yeah H3C Company launched a high-performance router, which mainly focus on Ethernet /Optical fiber /ADSL Access SMB The market and the Government, companies, Internet cafes and other network environments, such as high speed Internet Bandwidth of the Internet, businesses, schools and hotels.
ER3200Using professional 64Network processor clock speed up to 500MHz And supports a wealth of software features, such as IPSec VPN , Local area network, IP﹤-﹥MAC Address bindings ARP Preventing attacks, flow speed, double WAN Load balance policy routing, routing features such as the source address. It is H3C ER Mid-tier product series routers, medium ideal choice for Internet Café users and business users.
lHigh processing performance
ER3200 uses a 64-bit network processor clock speed up to 500MHz, in conjunction with high speed RAM DDRII high speed forwarding can achieve wire-speed forwarding hundred trillion.
lDual WAN load balancing
Network Load Balancing allows enterprise users according to the actual network traffic bandwidth allocation, and achieve the objective of full use of bandwidth. H3C domestic network user behavior and characteristics, targeted to launch the smart load balance and manual load balancing of two symmetric patterns meet user demand for bandwidth and flexible application of double lines. Intelligent load balancing according to user's actual bandwidth than the actual network traffic; Manual load balancing according to import routing tables to forward; Support policy routing table import/export feature, simply import the routing sheet can be achieved ' Netcom, Netcom, Telecom Telecommunications ' features.
ER3200 supports standard IPSec VPN, users can be achieved through simple WEB configuration point to point between the secure VPN connection of up to 168-bit 3DES encryption; H3C simultaneously combined with the user's networking features in ER3200 also supports IPSec are configured by domain name on VPN connections and NAT-t NAT across functions.
lMulti-LAN function (VLAN)
ER3200 supports multiple LAN function, enterprises can facilitate the Division of local area network in order to have multiple segments, reduce the effects of broadcast domains and ARP virus, separately for each local area networks you can configure the DHCP Server and firewall rules, the ER3200 can simultaneously support up to 16 internal local area network.
lARP virus dual protection
ER3200 IP ﹤-﹥ MAC address binding, gateway's ARP list is fixed, can effectively prevent ARP spoofing internal communications; In addition ER3200 free timing sending ARP mechanism can effectively avoid the? 构词成分。? PC poisoning caused by ARP attacks.
lNetwork traffic speed limits
BT, Thunder, P2P software on network bandwidth of excessive occupied will effect to network within other user of normal business, ER3200 through based on IP or based on NAT table items of network flow limited speed mechanism can effective to control single Taiwan PC of Shang/down flow and established of NAT table items of number, limit has P2P software on network bandwidth of excessive occupied, elastic bandwidth and guarantee has business on bandwidth of full using.
lOperational control (QQ/MSN/financial software)
The massive popularity of instant messaging software such as QQ/MSN, resulting in inefficient Office staff, unable to concentrate. ER3200 's unique control capability, you can easily limit the use of intranet applications such as user QQ/MSN, ER3200 supports on intelligence/analysts/flush/GF/Xeon/Everbright securities guoyuan securities financial software applications such as control functions. In addition, users can set critical to privileged users group users are not affected.

Lots of friends are asking a question, why I was always off line? Dropping of a variety of reasons, but one of the reasons is lack of bandwidth that cannot be ignored. So why would the bandwidth inadequate? An ancient story, a family with three brothers, and in bad years, leftover food must be eaten to tide you over until next year. Boss calculate, three people each only have 52 meals, unexpectedly, the third being length body, one meal ate 52 meals, this, two other brothers will have to starve.
Similarly, BT, and streaming media, games, ... ... These will take up a lot of bandwidth, as long as a few people are using, users do not have access to the bandwidth of the other, naturally led to dropped. Encounter such problems do? We are turning back to the tale of the three brothers, the eldest brother made a decision: three each have 32 meal, others eating one or two meals of rice, were not allowed to eat. Thus, while the three brothers are not eat, but can take.
In taking this approach, traditional QoS is assigned static bandwidth to different users, so that users would not affect each other. Apparently solves the problem. But new problems that the three brothers came, big weddings tubes of rice, the youngest workers. Third the rest of the bowls of rice, two brothers need to solve a problem: to eat or stay, because of the boss said not to eat someone else's.
Maybe you'll think this is funny, eating is not good. But the same problems to this scene is not so simple. Traditional QoS solutions like third meal, even if the three do not need people starve to death can not eat. This creates huge waste of bandwidth.
Don't you have a new solution to the problem of uneven-brother rice? (Three communications) company based on new flexible QoS design ER series has solved this problem.
Suppose a and b are two IP addresses, each was assigned 2M of bandwidth. When a, b the required bandwidth in excess of 2M a, a, and b only use 2M; If one of them is free, such as b only need 1M of bandwidth, then the rest of the 1M can be used. This is a good solution because of insufficient bandwidth issues dropped, which was owned by three brothers the possibility of full.
Not only that, QoS and more flexible application of ER series combined, has launched a series of very practical QoS features. Let us look at the green channel application of this feature.
According to statistics, playing 59% in proportion compared with other applications, with a small message, uses less bandwidth characteristics. Believe in the Internet Summit, many of them will encounter a card, has a big impact on business. So is there a way to run smoothly when the network busy?
In fact, encountered this problem also have similar things in the supermarket. Some customers buy only a few commodities, closing soon, but in one more time, and had to buy a lot of customers came in. The supermarket and the customer is not willing to see. Therefore, many supermarkets offer a fast-track, specifically for those who looked at buying less express checkout.
In the device application, this method can also be ported over, already widely used in professional. Similarly, ER series also offers a special function for green, why dedicated lanes for message smaller reserves. Not only that, in order to avoid wasting bandwidth, dedicated lanes for Green also incorporates a flexible design of QoS, ensuring network quality at the same time, make full use of limited bandwidth.
By introduction of the above we are not hard to see, ER series is tailored in order to network devices. Also order off line, slow the agony of friends, leave your worries to the ER series. believe me, Yes.
