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 sender does not overwhelm a slow receiver. In data link layer, flow control ...
PROBLEM TO BE SOLVED: To provide a flow control system in a transport layer protocol capable of suppressing the generation of a congesting state, and improving through-put by reflecting the band assignment information in a link for assigning a band to each terminal on the flow control of a ...

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...
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...
建立连接后,Controller 可以通过 LLDP(Link Layer Discovery Protocol,链路层发现协议)来完成 OpenFlow 网络的拓扑检测。 OpenFlow 消息类型 在OpenFlow 规范的最后一部分,主要详细定义了各种 OpenFlow 消息的类型和数据结构,例如:OpenFlow 协议的消息头等。Controller 和 Switch 之间通过 Cannel 来传递这些 Message,...

TCP (Transmission Control Protocol) has a different flow-control mechanism from the Ethernet. When a connection is initially established, TCP sends at a slow data rate to assess the bandwidth of the connection and to avoid overflowing the receiver or any other infrastructure in the network path,...
