随着IP在全球化网络中的兴起,许多高容量链接都正在努力避开加重ATM负担的“信元税(ATM信元中的信息头)”。但是,与大多数税种一样,没有办法完全避开这些支出。大多数电信业主都使用SONET(同步光纤网络)作为在公共网络中通过光纤传输数据的物理层标准,然后使用ATM作为数据链路层链接。ATM的信元税可 With the advent of IP in a globalized network, many high-capacity links are struggling to avoid the “cell tax” (message headers in ATM cells) that exacerbate the burden on ATMs. However, like most taxes, there is no way to get around these expenses altogether. Most telecommunications owners use SONET (Synchronous Optical Network) as a physical layer standard for transmitting data over optical fiber in a public network and then use ATM as a data link layer link. ATM cell tax can be
