摘要： A communications system comprises a memory which is shared by a plurality of users, each one receiving and transmitting messages to each other. In the present system, a message is composed of a plurality of data buffers stored in the memory and each data buffer is controlled and mapped to a unique direct control block (DCB) which stores the characteristics of said data buffer. The chaining of the DCB forms the whole message which may be multicast to a plurality of users. Therefore, in order to improve the performance of such communications system, one may duplicate the message as many times as necessary without re-writing the data in the personal storage of each user by using an indirect control block (ICB) which represents the message duplicated. Each ICB stores the characteristics of the message duplicated and points to a DCB. A field in the DCB enables to count the number of duplication of the message. The DCB and ICB stores different fields which are required in order to perform the operations of lease control block from the free queues, the operations of message enqueue in the user queue, the operations of message dequeue from the user queue, and the operations of message release to the free queues. Two separate free queues FDCBQ and FICBQ chaining the free DCB and ICB are provided and are controlled by two control blocks FDQCB and FIQCB.
The present apparatus and method may also be used for multicasting data buffer which composes a message by adding new fields in the ICB. In this case, the message to be multicast may have a content different from the original one, which requires therefore that to each ICB correspond a unique DCB.摘要翻译： 通信系统包括由多个用户共享的存储器，每个用户彼此接收和发送消息。 在本系统中，消息由存储在存储器中的多个数据缓冲器组成，并且每个数据缓冲器被控制并映射到存储所述数据缓冲器的特性的唯一直接控制块（DCB）。 DCB的链接形成可以组播到多个用户的整个消息。 因此，为了提高这种通信系统的性能，可以根据需要多次复制消息，而不用通过使用代表重复的消息的间接控制块（ICB）重新写入每个用户的个人存储中的数据 。 每个ICB存储复制的消息的特征并指向DCB。 DCB中的一个字段可以计算消息的重复次数。 DCB和ICB存储为了从空闲队列执行租约控制块的操作，用户队列中消息入队的操作，消息从用户队列出队的操作以及消息的操作所需的不同字段 释放到免费队列。 提供两个单独的空闲队列FDCBQ和FICBQ链接自由DCB和ICB，并由两个控制块FDQCB和FIQCB控制。 本装置和方法还可以用于通过在ICB中添加新的字段来组成消息的多播数据缓冲器。 在这种情况下，要组播的消息可以具有与原始消息不同的内容，因此要求每个ICB对应于唯一的DCB。

摘要： A traffic control apparatus implemented in a virtual path ATM communication system comprising a plurality of hops interconnected by physical links which comprise virtual paths including a plurality of virtual channels. A connection between two hops is defined as the combination of a physical link, a virtual path, and a virtual channel. Said connections are shared between a reserved bandwidth service and a best effort service. ATM data cells conveyed on said best effort service are routed from hop to hop by analyzing their virtual connection identifier. This is done by managing a pool of free queues being able to store ATM data cells, each of said queues storing all the incoming ATM data cells having the same virtual channel identifier.

摘要： The invention discloses a method and an apparatus for implementing the physical interface in a network element connected to a packet networks such as Asynchronous Transfer Mode (ATM) network. With the solution of the invention the physical interface functions can be integrated on one chip for more than one network port.
The physical interface is provided between port bit streams at media speed and word data flow transferred onto/from a bus which is under the control of the network equipement.
The solution of the invention consists first in grouping logics and storage elements by islands of more than one port. Furthermore, the logics and storage elements for statistical counting operations can be grouped for a processing generalized to all ports. Finally, the solution of the present invention takes into account two characteristics of the physical interface which are the different rates between network link media speed and bus access rate and the technology of the high density static imbedded RAMS used for hardware integration. The Flip/Flop pointer RAMs of Flip/Flop data RAMs are duplicated and some interface RAMs are created to transfer control data between the islands and the generalized processing logical blocks.摘要翻译： 本发明盘松动用于实现在连接到分组网络的网络元件的物理接口的方法和装置，以：如异步传输模式（ATM）网络。 与本发明的物理接口的功能可以在一个芯片上被集成为一个以上的网络端口的溶液中，物理接口在转印到/从一个总线的所有媒体的速度和字数据流，其是控制下端口位流之间提供 网络设备公司。 本发明的溶液中的第一besteht在由多于一个端口的岛屿分组逻辑和存储元件。进一步，对于统计计数操作的逻辑和存储元件可以广义至所有端口的处理进行分组。 最后，本发明的溶解速度考虑到物理接口的两个特征哪些网络链路速度和媒体总线访问和用于硬件集成高密度的静态嵌入RAMS的技术之间的不同的费率。 倒装/触发器翻转的指针的RAM /触发器的RAM被复制的数据和一些接口的RAM被创建的岛屿和广义处理逻辑块之间传递控制数据。

摘要： A communication system comprises a plurality of hops interconnected by links comprising a plurality of connections. The traffic between the hops is shared between a reserved bandwidth service and a non reserved bandwidth service. The control of said non reserved bandwidth service comprises a hop by hop backpressure mechanism. When the traffic entering a hop exceeds a low/high threshold, the backpressure mechanism generates start/stop backpressure primitives in order to resume/throttle the entering traffic. In case of congestion the mechanism is either able to selectively stop the connection contributing to the congestion without affecting the rest of the link traffic, or to globally stop the whole link traffic.

摘要： The invention includes a bridge having n ports (n > 1), each port being connected to a Token-Ring physical segment, each physical segment having one native Token-Ring workstation attached, said bridge comprising means for emulating to the workstations a single Token-Ring logical segment with a single Active Monitor and a single Ring Number.
The invention allows to replace a MAC-per-port by a centralized function inside a centralized processor; the frame handling function, due to the fixed and limited configuration (same bridge Active Monitor seen by all connected stations), does not require a multi-port bridge function, but a simpler switch function between ports. Bridge clocking is also simplified, and a cost effective UTP retiming solution is presented.摘要翻译： 本发明包括具有n个端口（n> 1）的桥，每个端口连接到令牌环物理段，每个物理段具有附接的一个本地令牌环工作站，所述桥包括用于向工作站仿真单个令牌 - 使用单个活动监视器和单个环号进行逻辑段。 本发明允许通过集中处理器内的集中式功能来替换每个端口的MAC; 帧处理功能由于固定和有限的配置（所有连接站所见的同一桥主动监视器）不需要多端口桥接功能，而是端口之间更简单的交换机功能。 桥接时钟也被简化，并提供了一个具有成本效益的UTP重新定时解决方案。

摘要： The invention discloses a method and an apparatus for use in the packet networks and particularly Asynchronous Transfer Mode (ATM) networks to support traffic of connections requiring a minimum bandwidth at connection establishment. The method and the apparatus further support any mixed traffic including connections requiring a minimum bandwidth, a fixed reserved bandwidth or no bandwidth at connection establishment.
The invention consists in using a first scheduler triggered by absolute time for scheduling the Minimum Service connections up to a rate corresponding to their reserved minimum bandwidth reserved, a second scheduler and a queue of Minimum Service connection identiers for communication between the two scheduling schemes.
With the dual scheduling mechanism of the invention the minimum bandwidth for connections reserving a minimum bandwidth at connection establishment is guaranteed in each point of the connection path and at any time, the level of fairness of the remaining bandwidth sharing depending on the quality of the second scheduler.-
