Abstract: Systems and methods are disclosed that allow for improved management and control of packet forwarding in network systems. Network devices and tool optimizers and a related systems and methods are disclosed for improved packet forwarding between network sources and destination tools in a network monitoring environment. The network devices and tool optimizers disclosed can include a graphical user interfaces (GUIs) through which a user can create and modify filters and select associated filter criteria for forwarding packets from input ports to output ports. The network devices and tool optimizers can also automatically generate filter rules and apply them to the appropriate filter engines so that packets are forwarded as desired by the user. The GUI can be configured to provide other features as well.

Network devices and tool optimizers and a related systems and methods are disclosed for improved packet forwarding between input ports and output ports. The input ports and output ports are configured to be connected to source devices and destination devices, for example, network sources and destination tools in a network monitoring environment. The network devices and tool optimizers disclosed can use a packet processing system whereby forwarding behavior is governed by matching packets in parallel against multiple user-specified packet filtering criteria, and by performing forwarding actions associated with all such matching filter criteria.

The input ports and output ports are configured to be connected to source devices and destination devices, for example, network sources and destination tools in a network monitoring environment. The network devices and tool optimizers disclosed can use superset packet forwarding, such that ingress filter engines are configured with ingress filter rules so as to forward a superset of packets to output ports associated with overlapping filters. Egress filter engines are configured with egress filter rules to then determine which of the superset packets are actually sent out the output ports.

Abstract: A telecommunications system and method which includes a transmitter, a first code generator for generating a noise code and a second code generator for generating a string-based code, wherein data which is transmitted by the transmitter is coded by the first and second code generators before transmission. One of the code generators preferably comprises a pseudorandom noise generator, and the other code generator preferably comprises a cyclic redundancy checking coder for assisting in deskewing of data. The telecommunications system allows the transmitter to dynamically request additional bandwidth from the telecommunications provider in order to efficiently transmit data. The present telecommunications system also substantially reduces skew experienced between the transmitter and the receiver.

Abstract: A terminal receives one or more input frames comprising one or more logical channels and may generate one or more output frames including the data received in the logical channels. Each logical channel is dispersed throughout the input frame in one or more timeslots, and each logical channel has an associated buffer. The data of each logical channel received from the timeslot(s) of the input frame(s) is stored in the corresponding buffer. The terminal uses channel sequencing for round-robin scheduling to transfer the data of the received logical channels, if present, in each buffer to one or more output frames. Channel sequencing may apply round-robin scheduling of service of buffers in ascending or descending order of non-empty buffers, accounting for newly filled buffers. Channel sequencing generates a binary word, termed a channels service request (CSR) word, with each bit of the CSR word corresponding to a buffer and indicating whether the buffer requests service.
