3GPP定义的LTE网络架构结构变得扁平化,无线RNC/BSC 消失,只有eNodeB.控制面使用MME进行处理,用户面使用SGW和PGW进行处理.相比GSM和UMTS,在逻辑接口上定义了S1/X2逻辑接口.eNB之间底层采用IP传输,在逻辑上通过X2接口互相连接.相邻eNodeB使用X2逻辑接口进行手机切换的控制和用户缓存数据的传送.这样的设计,主要用于支持UE 在整个网络内的移动性,保证用户的无缝切换. LTE网络的这些特点促使承载网络要有更强的承载能力.相比2G/3G的移动承载网络,需要移…

现有问题 随着IOT中智能设备多样性和数目的增加,IOT的灵活性,效率,可用性,安全性和可扩展性的问题越来越明显. 实验目标 按照高适应性,可用性,容错性,性能,可靠性,可扩展性和安全性的设计原则,构建一个安全分布的物联网网络的高性能架构 主要贡献 利用区块链技术为IOT提供分布式的SDN安全架构 提出一种更新架构中流规则表的技术 与传统模型比较 设计概述 架构图: 在这个架构中,SDN控制器已区块链的方式连接(?).同时,每个IOT网络包含OrchAPP,控制器和Shelter模块.OrchA…

A new sub-system, the core abstraction layer (CAL), is introduced to the middleware layer of the multi-core processor based modem board. This new module provides an abstraction for the multi-core FSL P4080 processor and its DPAA. For the deployment o…

A computer-implemented system and method for a lock-less, zero data copy messaging mechanism in a multi-core processor for use on a modem in a telecommunications network are described herein. The method includes, for each of a plurality of processing…

A buffer management mechanism in a multi-core processor for use on a modem in a telecommunications network is described herein. The buffer management mechanism includes a buffer module that provides buffer management services for one or more Layer 2…

摘要 本文提出了一种新方法,可以基于简单的爬山过程自动搜索性能良好的CNN架构,该算法运算符应用网络态射,然后通过余弦退火进行短期优化运行. 令人惊讶的是,这种简单的方法产生了有竞争力的结果,尽管只需要与训练单个网络相同数量级的资源.例如使用该算法,在单个GPU上训练12个小时就可以将CIFAR-10数据集的错误率降低到6%一下,训练一整天后能够降低到5%左右. 1.介绍 背景不再详述,我们可以知道的是传统的优化算法并不能实现神经网络架构的自动搜索是因为其架构搜索空间是 离散的(例如层数.层类型…
