摘要： A received data stream is formed into a stream of packets, each packet comprising a payload section of data and an overhead section. In forming the packets, a template overhead section is created for use by the stream of packets and this template is applied to the data to form the packets. This avoids the need to individually pass packets through a routing stack, thus reducing the processing demands on the processor which constructs the data packets and reducing the transmission delay experienced by data. The template overhead section can be formed by sending a packet through a routing stack. Another aspect describes apparatus for processing packets where a first processor processes signalling packets and a second processor processes real-time data packets. The first processor can be, used to create the template overhead section before passing the template information to the second processor where it can be used in forming the real-time data packets.
摘要翻译：接收到的数据流被形成为一个数据包流，每个数据包包括一个数据的有效负载部分和一个开销部分。在形成数据包时，创建模板开销部分以供数据包流使用，并将该模板应用于数据以形成数据包。这避免了通过路由栈单独传递数据包的需要，从而减少了构建数据包的处理器的处理需求，并减少了数据所经历的传输延迟。模板开销部分可以通过通过路由栈发送数据包来形成。另一方面描述了用于处理分组的装置，其中第一处理器处理信令分组，并且第二处理器处理实时数据分组。第一处理器可以用于在将模板信息传递到第二处理器之前创建模板开销部分，其中它可以用于形成实时数据分组。

摘要： Each of a plurality of data processing units that form a network relaying apparatus has a memory controller, a network controller, a processor, and independently accessible first and second memories. The memory controller includes a header information register for storing header information such as a header start position in a packet and a header length; a header position detection circuit for detecting a header position in the packet based on the header information contained in the header information register; and an inter-data processing unit transfer circuit for sending and receiving a packet to and from another data processing unit. The data processing unit stores into the first memory a packet received from the network or a packet transferred from another data processing unit, and at the same time stores only a header portion of the packet into the second memory. The processor reads the header portion of the packet from the second memory and analyzes it while at the same time the network controller and the inter-data processing unit transfer circuit write and read another packet to and from the first memory.

摘要： A system for probing one or more SVCs that enables a network manager station to setup a probe event in advance before a SVC is created. Upon the creation of the SVC, the data is captured and sent to the network management station without any further intervention required. In a first stage, a SVC originator is configured with a probing IE containing parameters to be included in the SETUP request message when SVCs are established. A unique identifier is included as one of the parameters in the probing IE and is used by the probing switch to detect a SVC that is to be probed. A PVC is established to the switch containing one or more SVCs that are to be probed. A probing port is configured on the switch and a range of VPI/VCIs are assigned to the port. A multicast connection is configured in the switch and traffic from the SVC originator is directed toward both the destination and to the probing port. In this fashion, the SVC traffic can be analyzed using diagnostic tools located remotely anywhere on the network.

摘要： There is disclosed, for use in a packet switched network, a redundant switch comprising 1) a primary packet router for routing a first stream of data packets from an input interface to an output interface of the redundant switch; 2) a secondary packet router for routing a second stream of data packets corresponding to the first stream of data packets from the input interface to the output interface; 3) a packet ID generator for attaching a unique identifier to each data packet in the first stream of data packets and attaching the same unique identifier to each corresponding data packet in the second stream of data packets; and 4) a comparator for comparing a first unique identifier associated with a first data packet processed by the primary packet router with a second unique identifier associated with a second data packet associated with the secondary packet router. The comparator, in response to a determination that the first and second unique identifiers match, causes the second data packet associated with the secondary packet router to be deleted.

摘要： Methods and systems for a distributed scalable hardware independent system that supports multiple functions regarding management and support of communications over a packet-based network. The communications supported by these methods and systems include, but are not limited to, Voice Over Internet Protocol (“VOIP”), voice over Asynchronous Transfer Mode (“ATM”), video conferencing, data transfer, telephony, and downloading video or other data. These methods and systems use a call agent, which is composed of various objects distributed along a CORBA software bus, for exercising call management over two endpoints communicating over a packet-based network.

摘要： A method for receiving a telephone call being transmitted on a network using Internet protocol (IP network) is disclosed. A request to handle the telephone call is received from an originating node on the IP network by a leader node on the IP network. A receiving node, having a receiving address, is selected to receive the telephone call. The receiving node is selected from a set of nodes comprising the leader node and at least one follower node, where each node in the set of nodes can receive the telephone call. The receiving address is transmitted by the leader node to the originating node using the IP network. The leader node causes the originating node to transmit the telephone call to the receiving node using the IP network.

摘要： There is disclosed a redundant switch comprising a primary controller capable of routing data packets from an input interface to an output interface and a secondary controller capable of performing data packet routing tasks performed by the primary controller after a switchover. The primary controller comprises: 1) an inbound queue capable of storing data packets inbound to the redundant switch; 2) an outbound queue capable of storing data packets outbound from the redundant switch; and 3) a control processor capable of processing a first data packet stored in the inbound queue and assigning an identifier to the first data packet, wherein the control processor further assigns the identifier to a second data packet, the second data packet associated with the first data packet and stored in one of the inbound queue and the outbound queue, wherein the first data packet is removed from the inbound queue only upon completion of all processing associated with the first data packet and wherein a removal of the first data packet from the inbound queue enables the second data packet to be transferred to the secondary controller during a switchover.
