摘要： Packets from multiple packet streams are transmitted in an output stream having substantially equally spaced packets using a scheduler which spaces the packets based upon the input stream speeds of the various input streams as well as the bandwidth of the transmission channel. Such a scheduler advantageously spaces the packets so that the maximum distance between two filled slots is never more than twice the minimum distance between any two filled slots. Such a system also advantageously allows the computation of the slot locations to be precomputed when the slots are initially allocated to streams, thereby allowing the scheduler to efficiently compute slot locations while the scheduler is receiving the input streams.
摘要翻译：使用基于各种输入流的输入流速度以及传输信道的带宽使分组空间的调度器，在具有基本上相等间隔的分组的输出流中传输来自多个分组流的分组。这样的调度器有利地使分组空间使得两个填充时隙之间的最大距离永远不会超过任何两个填充时隙之间的最小距离的两倍。当这些时隙最初被分配给流时，这样的系统还有利地允许计算时隙位置，从而允许调度器在调度器正在接收输入流时有效地计算时隙位置。

摘要： An asynchronous sample rate converter for converting a first sample rate in a signal to a second sample rate in the same signal is presented. The signal is first provided as input to an interpolator which upsamples the signal to form a signal having sample rate UFs1 where the upsampling factor U is a variable that is directly related to the ratio Fs2/Fs1. The resampler then linearly interpolates the upsampled signal to form a signal having sample rate DFs2. Finally, the resampled signal is downsampled to form a signal having sample rate Fs2.

摘要： A communications protocol interface is arranged at a central station of a telecommunications network and is responsive to a control message received from a network controller in accordance with a first message protocol to transmit the control message in accordance with a second message protocol to subscriber stations and is responsive to a control message received in accordance with the second message protocol to transmit the control message to the network controller in accordance with the first message protocol. The first message protocol is a balanced protocol with the communications protocol converter or the network controller able to initiate an exchange of information. The second message protocol is a master-slave protocol with the communications protocol interface acting as master. The second control message protocol operates over central station bus for communicating with at least one network element in the central station.

摘要： The present invention provides a system for handling telecommunications signals passed between a first and second element of a telecommunications network, the first element having an interface for transmitting and receiving signals in a first protocol, and the second element having an interface for transmitting and receiving signals in a second protocol. The system of the present invention comprises a first interface unit for receiving a first telecommunications signal transmitted in one of said first and second protocols between said first and second elements, the first interface unit being arranged to separate traffic bearing channels from non-traffic bearing channels within the first telecommunications signal. A traffic management element is then provided for performing a cross-connection function to map the traffic bearing channels to the appropriate format for the other of said protocols, whilst a protocol conversion element is provided for performing predetermined protocol conversion steps on the non-traffic bearing channels in order to regenerate those non-traffic bearing channels in the other of said protocols. Further, a second interface unit is provided for combining the channels as output by the traffic management element and the protocol conversion element in order to create a second telecommunications signal in the other of said protocols, the second interface unit being arranged to output the second telecommunications signal. Preferably, said first protocol has a concentrated format, and said second protocol has an unconcentrated format.

摘要： A network architecture includes a switch that can examine and selectively forward packets or frames based on information encapsulated in layer-2 information in the protocol stack. The switch segregates upstream traffic by data type and aggregates downstream Internet traffic with traffic from a local vertical services domain. The network architecture provides an efficiency way to insert vertical services.

摘要： A method and system for allowing a network of devices (nodes) which conform to standards with different physical interfaces and communication protocols to share a communication link. In one embodiment of the present invention, a 1394a compliant node is connected to a partially compliant bi-lingual 1394b node. The partially compliant bi-lingual 1394b node is connected to a fully compliant 1394b node. Thus, the partially compliant bi-lingual 1394b node provides a bridge between the 1394a node and the fully compliant 1394b node. The fully compliant 1394b node has a physical interface in compliance with the 1394b standard and arbitrates according to either the 1394b standard or the 1394a standard. The partially compliant 1394b node has a physical interface in compliance with the 1394b standard but arbitrates according to the 1394a standard. The 1394a node has a physical interface in compliance with the 1394a standard and arbitrates according to the 1394a standard.

摘要： A multidimensional ring network includes a plurality of network processing devices that are connected together with a plurality of individual ring networks. Packets are sent between any two network processing devices on the same ring network. Intermediate network processing devices, located on that same ring, between the sending and receiving network processing devices, do not add additional hops to the packet transfer. The intermediate processing devices, between the sending and receiving devices, simply pass the packets through to the next processing device on that ring. The packets are passed through to the destination processing device without the intermediate network processing devices having to read or process the packet headers. This allows the number of network processing devices on the individual ring networks and the number of individual ring networks in the multidimensional ring network to be increased without adding additional hops, and the associated latency, between the network processing devices.

摘要： This invention relates to a method and apparatus for controlling the flow of fiber channel (FC) data frames from a fiber channel link to a metropolitan area link of lesser bandwidth (a synchronous optical network (SONET)). The release of each data unit by a data source for transport onto the first channel is governed by a credit-based protocol whereby one data unit is released upon the provision of one credit unit. A first marker identifies a high limit H of the buffer at which a first condition occurs, H being less than N and the first condition applying when the number of data units in the buffer is greater than H. A second marker identifies a low limit L of the buffer at which a second condition occurs, L being less than H and the second condition applying when the number of data units in the buffer is less than L. A credit unit owed counter O counts the number of credit units which become owed to the data source when the second condition applies. A third marker Max identifies a maximum number of credit units that may be provided to the data source when the first condition applies and the value of the credit unit counter is greater than zero. Through this invention, effective means to control the flow of data from a fiber channel link to a metro area transport link without loss of frames or delay is provided.
