摘要： This document describes tools useful in relaying a data stream from a data device to a network tunnel, such as by enabling virtual switching using a provisional identifier to conceal a user identifier. These tools, for example, may use an inexpensive switch module to create virtual switch instances. To do so, the tools may assign data packets to a virtual switch instance by mapping the data packets to a particular provisional identifier and then modifying the data packets to include the provisional identifier. The switch module may then forward the data packets based on the provisional identifier rather than on the user identifier. The tools may remove the provisional identifier before forwarding the data packets to a destination.

摘要： Packet switch operating methods and packet switches provision a plurality of tunnels on a packet switch by associating each of the plurality of tunnels with a packet switch port and by configuring the packet switch to modify packets relayed by the tunnel to include a transport identifier associated with the tunnel. The tunnels of the plurality relay packets when permitted by a tunnel index. The plurality of tunnels and the tunnel index are associated with a virtual interface. The methods and packet switches also permit a first tunnel of the plurality of tunnels to relay packets by configuring the tunnel index to indicate the first tunnel. The tunnel index indicates only one tunnel. The methods and packet switches also enable a second tunnel of the plurality of tunnels to relay packets by configuring the tunnel index to indicate the second tunnel, thereby preventing the first tunnel from relaying packets.

摘要： Packet switch operating methods and packet switches assign a packet to a virtual interface. The virtual interface is associated with a plurality of tunnels. One of the plurality is designated a primary tunnel configured to accept packets. Other tunnels of the plurality are designated as backup tunnels and are configured to reject packets. The methods and packet switches also determine which of the plurality of tunnels is the primary tunnel and determine a packet switch port associated with the primary tunnel. The methods and packet switches egress the packet via the primary tunnel on the packet switch port associated with the primary tunnel.

摘要： Packet switch operating methods and packet switches receive a packet on a first port of the packet switch. The packet is addressed to a device that is in communication with a second port of forwarding circuitry of the packet switch and the packet has an Ethernet destination address field and an Ethernet source address field. The Ethernet destination address field includes a first address and the Ethernet source address field includes a second address. The methods and packet switches also forward the packet to an output queue associated with a third port of the forwarding circuitry, forward the packet from the output queue to the first port, and modify the packet so that the Ethernet destination address field comprises the second address instead of the first address.

摘要： This document describes tools useful in relaying a data stream from a data device to a network tunnel. These tools may utilize an encapsulation scheme to convert data packets from a user format to a tunnel format required by a network tunnel. Similarly, the tools may utilize a de-encapsulation scheme to convert data packets from the tunnel format to the user format required by the user. The tools may also forward the data packets from a user network to the network tunnel and vice versa, through a conventional switch module. In some embodiments, the tools do so by modifying the data packets to add a provisional identifier recognized by the switch module to map a particular data stream into a particular network tunnel.

摘要： A method, a statistics subsystem, and a system use a combination of commercially available high speed memory and high density low speed memory to mitigate cost, space, control, and power issues associated with storing counters for statistics updates, while meeting the growing width and depth needs of multi-hundred gigabit Carrier Class data network devices. The method, statistics subsystem, and system offer a Counter Management Algorithm (CMA) that relies on rollover bits stored within data of counters. An update to the low speed memory is substantially faster than a rollover time for the counter in the high speed memory thereby allowing statistics to be cached in the high speed memory while updates take place to the low speed memory.

摘要： This invention includes tools that prevent forwarding of a packet to a control plane of a packet switch. The tools receive a packet comprising indicia suggesting that the packet be forwarded to a control plane of a packet switch. After receiving the packet, the tools may modify the packet to prevent the packet from being forwarded to the control plane, intercept the packet before it is received by the control plane, or otherwise prevent the packet from being forwarded to the control plane. The tools may also forward the packet from a source port of a packet switch to a destination port of the packet switch without forwarding the packet to the control plane of the packet switch.
