Flow control is a technique that allows two stations working at different speeds to communicate with each other. It is a set of measures taken to regulate the amount of data that a sender sends so that a fast s
A data communication protocol can control the data flow between the transport layer and data link layer. 它提供两种数据流控制方式. It provides two data flow control. 第一种方式是当数据链路层的数据包缓冲区占用率小于第一阈值时,通知传输层暂停数据包传输,当占用率小于比第一阈值还低的第二阈值时,...
OpenFlow Controller:SDN 网络将传统的网络结构划分成了 Control Plane 和 Data Plane 两部分,OpenFlow Controller 属于 Control Plane 部分,通过约定的 OpenFlow 协议来远程管理 OpenFlow Switch,包括:增加、删除、修改 Switch 中的 Flow Tables 和 Flow Entries。 OpenFlow Switch:实现了 OpenFlow Protocol 的软/硬...
All OpenFlow channel messages must be formatted according to the OpenFlow protocol. OpenFlow channels are typically encrypted using Transport Layer Security (TLS), but can run on Transmission Control Protocol (TCP). An OpenFlow controller can manage multiple OpenFlow channels simultaneously, with ...
EOS implements Link Layer Discovery Protocol (LLDP) and the Data Center Bridging Capability Exchange (DCBX) protocol to help automate the configuration of Data Center Bridging (DCB) parameters, including the Priority-Based Flow Control (PFC) standard, which allows an end-to-end flow-control feature...
This is a model that adheres to the OSI Physical layer but that subdivided the Data link layer into two separate layers: the Media Access Control (MAC) layer and the Logical Link Control (LLC) layer. The MAC layer defines the access method to the transmission medium and consists of a ...

Flow协议获得网络的拓扑结构,是通过LLDP组件[7]发送LLDP(Link Layer Discovery Protocol)数据包到OpenFlow交换机,再收集并解析交换机反馈的LLDP数据包,从而实现网络拓扑感知。 3.2 大流监测模块 由于本文所提出的负载均衡机制是针对大流的,所以必须有一种方法将大流和小流区分开来。文献[8]对3种主流的大流监测机制...
