SNMPv1是一个不安全的协议，管理站(Manager)与代理(Agent)之间通过 (56) 进行身份认证，由于认证信息没有加密，所以是不安全的。1998年公布的SNMPv3定义了基于用户的安全模型USM，其中的认证模型块结合 (57) 算法形成认证协议，产生了一个96位的报文摘要。SNMPv3还定义了基于视图的访问控制模型VACM。在这个模型中，用户被分成组，属于同一组的用户可以有不同的安全级别，其中 (58) 是最高安全级别。RFC1757定义的RMON管理信息库是对MIB-2的扩充，其中的统计组记录 (59) 的管理信息，而矩阵组则记录 (60) 的通信情况。

1 Sometimes, over a span of many years, a business will continue to grow, generating ever-increasing amounts of cash, repurchasing stock, paying increased dividends, reducing debt, opening new stores, expanding production facilities, moving into new markets, etc., while at the same tune its stock price remains stagnant (or even falls). When this happens, the average and professional investors alike tend to overlook the company because they become familiar with the trading range. Take, for example, Wal-Mart. Over the past five years, the retailing behemoth has grown sales by over 80%, profits by over 100%, and yet the stock price has fallen as much as 30% during that timeframe. Clearly, the valuation picture has changed. An investor that read the annual report back in 2000 or 2001 might have passed on the security, deeming it too expensive based on a metric such as the price to earnings ratio. Today, however, the equation is completely different—despite the stock price, Wal-Mart is, in essence, trading at half its former price because each share is backed by a larger dividend, twice the earnings power, more stores, and a bigger infrastructure. Home Depot is in much the same boat, largely because some Wall Street analysts question how fast two of the world’s largest companies can continue to grow before their sheer size slows them down to the rate of the general economy. Coca-Cola is another excellent example of this phenomenon. Ten years ago, in 1996, the stock traded between a range of﹩36.10 and﹩54.30 per share. At the time, it had reported earnings per share of﹩1.40 and paid a cash dividend of﹩0.50 per share. Corporate per share book value was﹩2.48. Last year, the stock traded within a range of﹩40.30 and﹩45.30 per share;squarely in the middle of the same area it had been nearly a decade prior! Yet, despite the stagnant stock price, the 2006 estimates Value Line Investment Survey estimates for earnings per share stand around﹩2.16 (a rise of 54%), the cash dividend has more than doubled to﹩1.20, book value is expected to have grown to ﹩7.40 per share (a gain of nearly 300%), and the total number of shares outstanding (未偿付的，未完成的) has actually decreased from 2.481 billion to an estimated 2.355 billion due to the company’s share repurchase program. This passage is probably a part of______.
