本月(2011年2月)，IANA宣布它已经分配掉最后一批剩余的IPv4地址。
This month (February 2011), IANA announced that it has allocated the last batch of remaining IPv4 addresses.
超过90%的IPv4地址已经被分配完了。
Heidemann的IP映射也反映出虽然这些IPv4地址已经分配出去了，但是大部分——大约有百分之八十五——事实上并没有的到使用。
Heidemann's IP mapping also revealed that while the bulk of those IPv4 addresses have been handed out, a majority of them — roughly 85 percent — aren't actually in use.
与之对照，IPv 6采用了128位地址，可以分配出数十亿个新地址——专家估计，这足够为地球上每棵草的所有叶片分配独一无二的地址。
By contrast, IPv6 USES 128-bit web addresses, creating billions of possible new web addresses - experts estimate it could assign a unique address for every blade of grass on the planet.
不幸的是，32位地址空间非常吃紧，限制了随机分配地址的范围和效率（hamperingits effectiveness）。
Unfortunately the 32-bit address space is pretty tight, leaving little room for randomization andhampering its effectiveness.
而不会像IPv4的43亿地址极限，IPv6有足够的地址，给地球上的每一个人都会分配到数十亿。
Rather than 4.3 billion address limitation of IPv4, IPv6 has enough addresses that every single person on the planet could have billions upon billions assigned to them personally.
世界IPv6日已经达到了它的目的：引起人们对IPv6需求的重视，尤其是现在IPv4地址已经分配殆尽，IPv6的测试工作已经提升到了互联网的级别。
World IPv6 Day has achieved its purpose: drawing attention to the need of IPv6, especially now that IPv4 addresses have run out, and testing IPv6 at the Internet level.
所有这一切导致的后果就是可分配的IPv4地址不足40亿。
The net effect of all this is that there's less than 4 billion IPv4 addresses to go around.
CPU节点表示了一个关于编址的最简单的例子。每个CPU都分配了一个唯一的id，并且没有CPU id相关的大小信息。
The CPU nodes represent the simplest case when talking about addressing. Each CPU is assigned a single unique id, and there is no size associated with CPU ids.
基于广播信道及多址接入信道的概念，提出了一种新的半双工中继协议，并对该协议下的资源分配问题进行了研究。
Based on the concepts of broadcast channel and multiple access channel, a novel half-duplex relay strategy was proposed, and optimal resource allocation under this strategy was investigated.
基于时分多址技术，提出了一种改进的动态带宽分配算法，结合了轮询机制和申请的优先级。
Based on TMDA technology, a modified dynamic bandwidth allocation algorithm, which integrates Polling scheme and requesting priority, is proposed.
这里将这种网络内没有分配统一地址的状态称为不稳定状态。
Here the uniform distribution of this network does not address the state known as instability.
典型的多址协议有固定分配、随机多址和轮询接入三种。
The typical multiple access methods are fixed, random and polling multiple access.
采用遗传算法搜索子载波最优分配方案，对多用户正交频分复用多址接入(OFDMA)系统资源分配问题进行了研究，提出了一种多载波比例公平调度算法G - PFS。
Focusing on the resource allocation problem in multi-user orthogonal frequency division multiple access (OFDMA) systems, a multi-carrier proportional fair scheduling algorithm, G-PFS, is proposed.
利用降低码片速率有效降低每路信号占有的带宽，将每路信息的比特分配在不同的调制载波上，减少了各路信号间的多址干扰。
Frequency width is compressed by decreasing signature-code speed and using bit-signal modulates by different carrier so as to decrease multi-user interference.
