摘要： Methods, apparatuses and computer readable storage mediums provide virtual network slicing without duplicating network configuration data (also referred to as network configuration information) on a slice-by-slice basis by maintaining a single physical network datastore including network configuration information for all network entities in the physical network, but generating slice views for respective virtual network slices as needed over time. Methods, apparatuses and computer readable storage mediums also enable configuration of a plurality of virtual network slices sharing a physical network infrastructure.

摘要： Embodiments are directed to monitoring a network flow. A characteristic of the monitored network flow may be compared to a criterion. A filter may provide the criterion. Filtered network traffic may be provided based on the filter and the comparison. A rule may be provided based on the filtered network traffic, such that each rule is associated with one or more rule prologues and one or more rule actions. The one or more rule prologues may be executed on the filtered network traffic to provide one or more satisfied rule prologues. One or more of the one or more rule actions may be executed based on the one or more satisfied rule prologues, such that the one or more executed rule actions and the one or more satisfied rule prologues are each associated with a same rule.

摘要： A computer-implemented method classifies a packet received from a network. The method comprises receiving the packet having header information and a rule-set that indicates a plurality of actions to perform on the packet. A geometric representation of the rule-set is constructed having a plurality of dimensions and rule boundaries. At least one rule boundary and dimension of the geometric representation is split to form a search structure having a plurality of nodes. Each node in the plurality of nodes is constrained to a predetermined memory threshold. The search structure is searched using the header information to obtain a rule in the rule-set that indicates an action to take on the packet.

摘要： A method is implemented by a network device for the insertion of a timestamp into a packet header. The insertion of the timestamp into the packet header enables performance metrics in a software defined networking (SDN) network. The method includes receiving a packet on an ingress port of the network device, determining whether the received packet matches timestamp criteria, upon determining that the received packet matches the timestamp criteria, copying a value in a global timestamp packet register in a flow control pipeline into a header of the received packet, and forwarding the received packet toward a destination.

摘要： Technologies for tracing network performance in a high performance computing (HPC) network include a network computing device configured to receive a network packet from a source endpoint node and store the header and trace data of the received network packet to a trace buffer of the network computing device. The network computing device is further configured to retrieve updated trace data from the trace buffer and update the trace data portion of the network packet to include the retrieved updated trace data from the trace buffer. Additionally, the network computing device is configured to transmit the updated network packet to a target endpoint node, in which the trace data of the updated network packet is usable by the target endpoint node to determine inline performance of the network relative to a flow of the network packet. Other embodiments are described and claimed herein.

摘要： A wireless device for narrowband MTC may use a sampling rate that is less than a default sampling rate associated with a wireless carrier for reduced processing complexity. The device may operate in a narrowband portion of a system bandwidth, and the sampling rate may be less than that used by devices monitoring the whole bandwidth but with the same subcarrier spacing or symbol duration. A reduced sampling rate implies a shorter IFFT for each symbol, but in order to align the subframe timing with the conventional subframe timing, three solutions are proposed: 1) reduced sampling rate for useful portion and CP but alternating CP lengths between symbols. 2) dual sampling rate processing: first sampling rate for useful portion and part of CP and sampling rate conversion and CP filling samples added at second sampling rate. 3) reduced sampling rate (1.92 MHZ) with overlapping symbol windows (ie a postfix overlapping the CP of the next symbol) to improve spectral shaping. The size of a cyclic prefix (CP) may be adjusted based on the sampling rate to align subframe timing boundaries for signals of different sampling rates.
摘要翻译： 用于窄带MTC的无线设备可以使用小于与无线载波相关联的默认采样速率的采样速率，以降低处理复杂度。 设备可以在系统带宽的窄带部分中操作，并且采样速率可以小于监视整个带宽但具有相同子载波间隔或符号持续时间的设备使用的采样速率。 降低的采样率意味着对于每个符号来说较短的IFFT，但是为了使子帧定时与常规子帧定时对准，提出了三种解决方案：1）有用部分和CP的缩减采样率，但是符号之间交替的CP长度。 2）双采样率处理：以第二采样率添加的有用部分和部分CP和采样率转换和CP填充样本的第一采样率。 3）具有重叠符号窗口（即与下一个符号的CP重叠的后缀）的采样率（1.92MHZ）降低，以改善频谱整形。 循环前缀（CP）的大小可以基于采样率来调整，以对准不同采样率的信号的子帧时序边界。
