摘要： A method for reducing the capacity of the virtual concatenation group and a virtual concatenation group communication network, the keystone is that, removes one link by removing the downlink member firstly and removing the uplink member secondly, without any blight to the service, and the operation freeness is increased for the user, and the operation limitation is eliminated, and the possibility of mistake operation is avoided radically (for that uplink removing first and downlink removing second are supported by this protocol itself). It also avoids the blight to the whole virtual concatenation service that caused by removing downlink members firstly according to the prior art. And the state flow of this embodiment is completely based on the primary state flow of the LCAS, and the compatibility and mutual maneuverability between devices are ensured furthest.

摘要： A data traffic network element for a line switched ring network. The network has a data ingress point for receiving ingress payload data having multiple working connections transported in respective timeslots, at least one of the connections being passed through the network element. The network also has a data egress point for releasing egress payload data in the ring network including the connection. The traffic network element includes a timeslot interchange entity for interchanging the connection to a timeslot in the egress payload data different from the timeslot of the connection in the ingress payload data, wherein data over the connection is transported to and from said network element in different timeslots. One advantage of the network element with the timeslot interchange is the ability to provide a better bandwidth utilization by allowing to set connections over otherwise stranded bandwidth. In a specific example of implementation, the ring network is a BLSR ring network that uses the SONET protocol for data transmission. The timeslot interchange entity has the ability to store information identifying currently implemented timeslot interchanges. This information is available for access by protection switching logic during protection switching operations.

摘要： An approach for managing dynamic traffic on a shared medium, for example, on a SONET ring, makes use of a central arbiter that communicates with stations coupled to the medium. Each station makes requests to change bandwidth for dynamic traffic entering the medium at that station, and also implements a congestion avoidance algorithm that is coordinated with its requests for changes in bandwidth. The central arbiter responds to the requests from the stations to provide a fair allocation of bandwidth available on the shared medium.

摘要： A system for partitioning SONET frames into logical channels in a SONET ring is described. A SONET frame comprising a number of STS frames is subdivided into a plurality of logical channels. Each logical channel includes one or more STS frames. A protection layer is assigned to each logical channel. The protection layer may correspond to protection provided by the SONET ring or protection provided by network elements and specific to the type of data traffic transmitted within each channel. If SONET level protection for a particular logical channel is disabled, the bandwidth for the STS frames comprising that channel may be allocated among two or more nodes in the SONET ring.

摘要： A packet data transmission node is switched asynchronously without interruption of data transmission and with a minimum of circuit complexity. In particular, a packet channel is permitted to "breathe", gaining bandwidth when additional bandwidth becomes available from other temporarily unused digital channels and losing such addition bandwidth when such unused digital channels revert to other use. To permit such uninterrupted asynchronous operation, a "pad" or "throw away" character is defined which is ignored or discarded when it is received by another packet network node. Such a "pad" or "throwaway" character is unique only in the sense that is is distinct from and may not be confused with characters or bytes which may occur in normal data transmission sequences.
摘要翻译：分组数据传输节点被异步地切换而不中断数据传输并具有最小的电路复杂性。特别地，允许分组信道“呼吸”，当附加带宽从其他临时未使用的数字信道可用时获得带宽，并且当这种未使用的数字信道恢复到其他用途时丢失该附加带宽。为了允许这种不间断的异步操作，定义了一个“pad”或“throw away”字符，当被另一个分组网络节点接收时，被忽略或丢弃。这样的“垫”或“一次性”字符仅在与正常数据传输序列中可能出现的字符或字节不同且不会混淆的意义上是唯一的。

摘要： A method for allocating a resource in a periodic frame of an asynchronous digital satellite network to each packet burst of sporadic connections transmitted by earth stations. A resource allocation request, such as for a time slice in a data subframe of the frame, is transmitted by the earth station to a central network management station at the start of burst reception and therefore well before the earth station has received the whole burst from one of the user stations. Each of the resource allocation requests relating to the bursts of a connection is granted since the request contains no information on the burst. Connection request acceptance or rejection is decided according to an algorithm which prevents network overload and performance collapse.
摘要翻译：一种用于将异步数字卫星网络的周期性帧中的资源分配给由地球站发送的零散连接的每个分组突发的方法。诸如对于帧的数据子帧中的时间片的资源分配请求在突发接收开始时由地球站发送到中央网络管理站，因此在地球站已经从地球站接收到整个突发之前很好地发送其中一个用户站。由于该请求不包含有关突发的信息，因此授予与连接的突发相关的每个资源分配请求。连接请求的接受或拒绝是根据防止网络过载和性能崩溃的算法来决定的。
