ISA带宽管理软件 Bandwidth 使用指南
·和ISAServer严密集成，并且支持远程管理；·支持实时带宽限制和流量总额限制；·支持关于IP和用户账户进行限制；·支持限制分组总额或对分组中的单个IP/用户进行限制；·能够限制用户的并发连接恳求数量，这个是对ISAServer连接限制缺陷（只具有两种连接限制种类）的很好补充；·支持对Web缓存访问不进行带宽限制；·能够实时监视每条规则运行的状况和细节；·功能极高，对系统功能影响极低；·关于最终用户是透明的，无需用户安装任何客户端软件；·支持HTTP加快功能；·和ISAServer严密集成（当然这也是它的下风，它只能和ISAServer一同使用）；·支持对用户账户进行带宽控制；·支持限制用户的并发连接恳求数；·功能极高，对系统功能影响极低；·支持HTTP加快功能；·支持对Web缓存访问不进行带宽限制；BS和ISAServer的严密集成首要发挥在以下四个方面：·BS的配置数据与ISAServer的配置数据存储在一同；·BS的管理控制台与ISAServer的管理控制台集成在一同；·BS作为ISAServer的使用程序选择器运行；·BS使用ISAServer中的策略元素来作为自个的策略元素；BS仅仅作为ISAServer的使用程序选择器运行，它不会影响ISAServer的原有规则和配置，它仅仅在ISAServer的基础上提供了带宽管理功能，可是它比ISAServer的防火墙策略具有更低的优先级，因而假如要对用户实施带宽管理，你首先必须在ISAServer的防火墙策略中许可这个用户的访问。别的，BS无法管理非TCP/UDP协议如ICMP协议等等，一起BS不会管理本地主机和其他非外部网络（如内部网络、DMZ网络）之间的连接。(·Tightly integrated with ISAServer and support remote management; ·Support real-time bandwidth limit and total traffic limit; ·Support limit on IP and user account; ·Support limit group total or limit individual IP/user in group; ·Can Limit the number of concurrent connection requests of users, which is a good complement to the ISAServer connection limit defect (there are only two types of connection limits); Support no bandwidth limit for Web cache access; Ability to monitor the running status of each rule in real time and details; ·Highly functional, extremely low impact on system functions; ·Transparent to end users, no need for users to install any client software; ·Support HTTP acceleration function; ·Strictly integrated with ISAServer (of course, this is also its disadvantage, It can only be used together with ISAServer); Supports bandwidth control for user accounts; Supports limiting the number of concurrent connection requests for users; Cache access is not limited by bandwidth; the tight integration of BS and ISAServer is mainly in the following four aspects: The configuration data of BS and ISAServer are stored together; The management console of BS is integrated with the management console of ISAServer ; BS runs as the application selector of ISAServer; BS uses the policy element in ISAServer as its own policy element; BS only runs as the application selector of ISAServer, it will not affect the original rules and configuration of ISAServer , it only provides bandwidth management functions on the basis of ISAServer, but it has a lower priority than the firewall policy of ISAServer, so if you want to implement bandwidth management for users, you must first allow the user's firewall policy in the ISAServer access. In addition, the BS cannot manage non-TCP/UDP protocols such as ICMP protocols, etc., and the BS will not manage the connection between the local host and other non-external networks (such as internal networks, DMZ networks).)
