    Overview

    BAUDCOM 7300 gateway series are 64-bit MIPS multi-core gateways developed by Shanghai Baudcom Communication Device Co., Ltd. As a new generation of cost-effective and comprehensive flow-control gateways, they have private ASIC switching chips and are used at advanced cases for large or medium enterprises, broadband communities, campus networks, or carriers.

    BD-R7300 gateways are strong in data processing, flexible in a variety of mainstream bandwidth access environments and various in providing sound bandwidth distribution solutions, all of which are means of effective utilization of bandwidth resources. In addition, these products provide network behavior management, P2P control, VPN networking, firewall, ARP cheat prevention and vicious attack prevention.

    These gateways integrate multiline, NAT sharing, security and elastic rate limit, so they are to users an all-in-one comprehensive solution with high performance, high reliability and high performance-to-cost ratio.

     

    Main Characteristics

    High reliability and stability

    After over a decade years of research experience in the data communication network field and studious research on broadband user’s requirements, BAUDCOM broadband solutions have won customers’ trust in all respects, especially in hardware or software design and in systematic strong ability, and these routers can run reliably for a long time in harsh environments such as high temperature, poor ventilation and bad grounding.

     

    Strong data-processing capability

    BD-R7300 adopts the 64-bit MIPS multi-core processor and the private ASIC switching chip, so it has high throughput and a high performance-to-cost ratio.   They secure the reliable and rapid operation of such kernel functional modules as NAT, VPN, P2P identification and control, and firewall in an environment of multi-user and large flow.

     

    Flexible multi-WAN access

    A maximum of 8 WAN ports can be used for networking; the access modes such as Ethernet, FTTB optical fiber, ADSL and cable are supported; the multiline policies such as “bandwidth nesting”, “intelligent routing” and “master/standby” are supported.

     

    Versified flexible flow-control policies

    BAUDCOM flow-control gateways have adopted the advanced 7-layer characteristic code identification technology and various policy databases, so they can be used in the following application cases such as HTTP, MAIL, database, P2P download, VOD and VoIP. According to customers’ requirements, they can limit applications with high bandwidth but low priority such as P2P and VOD, and first process those with the high priority and low bandwidth.

    At the same time elastic and effective bandwidth distribution solutions can be set flexibly according to the customer quantity: when free, the network will increase the bandwidth for each customer automatically; when busy, the bandwidth will surely be averaged, not being over-preoccupied. The assisting strategies (i.e. big-flow host limitation mechanism, flow outburst factors and optional user punishment/limitation) bring various and feasible methods for network management.

    Two BAUDCOM bandwidth distribution and control policies integrate with each other, greatly improving the bandwidth usage. In case of large flow, BD-R7300 gateways can guarantee those prior services in enterprise networks or cyberbars. Users can be provided an orderly, effective and secure network environment by these gateway series.

     

    Various behavior management policies

    They have the following functions:

    l       Identify and control common IM software such as QQ and MSN based on the application layer;

    l       Support the white list;

    l       Identify frequent P2P programs based on the application layer;

    l       Block relevant services and conducting rate limit;

    l       Shield the stock, entertainment or purchase website based on the policy database;

    l       Update the policy database freely online.

     

    Multiple anti-attack policies

    BD-R7300 series is strong in preventing attacks. It can make a correct statistics and detailed analysis on all types of packets such as ARP, IP, ICMP, TCP and UDP, so the attacks can be automatically prevented once they are found and the alarm information can also be provided for rapid fault locating and removing.

    For ARP cheat, BD-R7300 gateways provide IP-to-MAC binding, ARP-to-SCAN technology and free ARP and other mechanisms to secure the intranet; If working with BAUDCOM private switching products, these routers can be armed with DHCP-Snooping. In this way, ARP cheat cannot hide itself and it is 100% sure that ARP cheat can be detected and prevented.

     

    Perfect log management

    BAUDCOM secure flow-control gateways can provide varies kinds of log information, including URL filtration, internet surfing recording and query, and vicious attack records. Hence, customers can further know the detailed running status of the whole network and locate and solve network faults.

     

    All-around VPN functions

    BD-R7300 series supports VPN protocols such as L2TP, PPTP, GRE, IPIP and IPSec, and provides encryption algorithms, so that an overall solution can be provided to the construction of the remote office, the mobile office and the virtual private network; they also have the hardware encryption unit in their CPUs and hence have a strong ability of encryption.

     

    User-friendly Web page

    A simple and clear Web graphic interface is provided for configuration, so you can easily operate it even you are not professional.

    Most of all, all kinds of configuration navigation help you to master all kinds of core functions.

     

    Life-long free software upgrade

    The IOS system of network products, the supplementary 7-layer characteristic database and the security policy database, all of which are provided by BAUDCOM, have free download/upgrade services.
