In local networks, the data link layer often assumes the task to regulate access to a shared medium 在本地网络中,数据链路层假设任务控制使用共享媒介。
Web-based photo / movie / general media management and sharing application geared towards sharing media with friends and family 网页处理模式的照片、视讯与一般多媒体内容的管理与分享应用工具。
Some of atm's benefits include its cell-based switching scheme that protects traffic from the latency problems it faces over shared media atm的优势包括基于信元的交换方案保护信息流,避免了在共享介质上面临的老问题。
At the same time, these companies are migrating to higher speeds across the lan, replacing 10m bit / sec shared media with dedicated 10m / 100m bit / sec switched connections 同时,这些公司在局域网上向更高速度过渡:用专用的10兆/100兆位/秒交换式连接替代10兆位/秒的共享式传输介质。
In 1994, the school s name was changed to tokyo galaxy language academy with the aim of providing japanese language training that would create a global network with japanese as the shared medium 1994年学校易名为东京银星语文学院,我校以培养看负21世纪的环球沟通网罗的人材为目标。
The downstream channel is a point-to-multipoint broadcasting channel with a wider bandwidth, while the upstream one is a multipoint-to-point share medium with a narrow bandwidth hfc网络下行信道采用一点对多点的广播方式,用户共享下行资源实现比较简单。上行信道是一个多点对一点的媒体共享信道。
We stress on the problem of local area computer network's sharing media access, and bring forward the resolve for ethernet of the special congestion of throughput decrease greatly at heavy loads 提出以太网重负载下吞吐量严重降低这种特殊的拥塞状况的解决方案,并研究了实时通信如何减少延时和访问时间不确定性问题。
". the use of individual mac addresses with eapol permits the use of eapol in shared media lan environments, and, in particular, this has been allowed in order to support the use of port-based network access control in ieee 802.11 wireless lan infrastructures “将个体mac地址与eapol(7.8)一起使用,可以允许在共享媒体局域网环境中使用eapol,而且特别是它已经过允许,以便支持在ieee802.11无线局域网基础结构中使用基于端口的网络访问控制。
Since epon is a multipoint-to-point system, a major feature for this new architecture is the use of a shared transmission media between all users; hence, medium access control arbitration mechanisms are essential for the successful implementation of epon : ensure a contention-free transmission and provide end users with an equal access to the shared media 由于epon特殊的点到多点的网络拓扑结构,在上行方向各个光网络单元onu(opticalnetworkunit)共享信道带宽,采用时分多址tdma的方式发送数据,因此需要采用媒体接入控制(mac)协议来协调各个onu的发送,避免上行数据的冲突。
Attempting to use eapol in a shared medium environment that does not support the use of secure associations renders port-based network access control highly vulnerable to attack; for example, station a can mount a successful denial-of-service attack on station b simply by issuing an eapol-logoff packet using station b s individual mac address . " see ieee 802.1x specifications, page 21, section 7.9, lines 34-39, available to link to in the 在不支持使用安全关联的共享媒体环境中进行使用eapol的尝试会导致基于端口的网络访问控制极易受到攻击;例如,工作站a只要发出一个使用工作站b的个体mac地址的eapol-logoff包,就能够在工作站b上挂装一个成功的拒绝服务攻击。”
