在进行网络建设时,只考虑网络硬件和软件的直接成本而不考虑网络管理成本是非常片面的,这一点已经得到企业管理者越来越多的共识。随着网络技术应用领域的不断扩大,网络管理成本的重要性已凸现出来,而被称为网管“黑洞”的管理成本则成为用户总体拥有成本(TCO)的重中之重。 When conducting network construction, considering the direct costs of network hardware and software without considering the cost of network management is very one-sided, which has been increasingly recognized by enterprise managers. With the continuous expansion of network technology applications, the importance of network management costs has emerged, while the cost of management known as “black hole” of network management has become the top priority for users’ Total Cost of Ownership (TCO).
