摘要： A packet transmission protocol, which operates in a full-duplex mode in a system, which includes a transmitter, a receiver, and a communications network having a channel that logically ties the transmitter and the receiver together through the network, is disclosed. The receiver regularly sends a control packet to the transmitter. The control packet includes a plurality of data fields, which are useful in describing the state of the receiver to the transmitter. The transmitter receives the receiver's control packet and analyzes the data. If it finds that a particular block of packets had been received with an error (or not received at all), then the transmitter retransmits the block. The protocol includes two windows for controlling the volume of information, e.g. number of blocks, in the network. The first window, called the network window, is used to limit the data in the network so that network buffer resources can be sized economically and yet in a manner such that there will not be an excessive loss in the number of packets transmitted through the network. The second window, called the receiver flow control window, is typically larger than the first window and is used to assure that packets are not dropped, or lost, at the receiver. By having the second window larger than the first window, throughput can be increased while still meeting a commitment to the network that limits the number of packets in the network to a value consistent with economical buffer sizing. Typically, the first window is set to the value of the bandwidth delay product of the channel and the second window is set to a value at least twice that of the first window. The functions related to receiver flow control and network congestion control can be decoupled.

摘要： A facility is provided for use in a packet switch to control unnecessary multiple retransmissions of a data packet. In an exemplary embodiment of the invention, such control is achieved by tracking in a list the sequence numbers of transmitted data packets and retransmitting a data packet only if its sequence number appears in the list prior to the sequence number of the last data packet that is received correctly by a receiver. The sequence number associated with a retransmitted data packet is deleted from the list and then appended to the list to place the number in proper relationship with the sequence numbers of data packets transmitted after the initial transmission of the retransmitted data packet.

摘要： A method and system for provisioning circuits on multiple parallel links with a single setup message is disclosed. A setup message specifying links in a circuit path is transmitted to switches along the circuit path. If a switch determines that a link specified in the setup message has insufficient bandwidth for the circuit, the switch substitutes a parallel link having sufficient bandwidth for the specified link in the circuit path. The setup message can indicate whether substitution for a link is permitted. This can be used to prevent substitution for links when provisioning service routes for new circuits in order to maintain diversity requirements, while allowing substitution for links when provisioning restoration routes for failed circuits in order to reduce restoration time.

摘要： Disclosed is a method and apparatus for provisioning a label switched path (LSP) between two endpoints executing a first set of MPLS functions. The method and apparatus associates a first node with the first endpoint and a second node with the second endpoint. The first node is designated as the source. Both the first and second nodes execute a second set of MPLS functions, wherein the second set of MPLS functions include the first set of MPLS functions and additional MPLS functions. As the source, the first node provisions a first MPLS path (i.e., LSP) between itself and the first endpoint. The first node then provisions a second MPLS path (i.e., LSP) between the first node and the second node. The first node then transmits a message to the second node instructing the second node to provision a third MPLS path between the second node and the second endpoint. The three MPLS paths are bridged at the first and second nodes to complete the LSP between the two endpoints.

摘要： A generalized leaky bucket mechanism allowing multiple burst sizes and drain rates. The generalized leaky bucket includes multiple token pool sizes and drain rates, wherein the leaky bucket gradually steps up to larger token pool sizes and steps down as soon as user bursts utilize the increased number of tokens. This allows bursts of various sizes with frequencies which decrease with the burst size. Control of when to step up to higher burst sizes is accomplished through simple trigger conditions which operate to selectively increment the token pool count of the leaky bucket at these times.
