摘要： Techniques for performing distributed provisioning of packet classification rules in an extended bridge are provided. According to one embodiment, a controlling bridge (CB) of the extended bridge can receive a command to create or delete a packet classification rule for one or more virtual ports of the extended bridge. The CB can further determine a port extender (PE) of the extended bridge that hosts one or more physical ports corresponding to the one or more virtual ports. The CB can then transmit a message to the PE with instructions for creating or deleting the packet classification rule in a ternary content addressable memory (TCAM) of the PE.

摘要： Wi-Fi flows are intelligently bridged in a software-defined network (SDN) controller of a wireless communication network that centrally coordinates data plane behavior. A default mode tunnels packets received at an access point to the SDN controller for layer 2 routing decisions. A bridging policy concerning bridging of specific types of traffic flows for the wireless communication network is received at the SDN. Data plane traffic flow for each of a plurality of access points distributed around the wireless communication network is centrally monitored. New data streams tunneled to the SDN controller are matched to bridging policies with deep packet inspection. Responsive to matching, the tunnel mode is converted to a bridge mode by sending a rule concerning the new data stream to the access point. As a result, subsequent packets of the new data stream are transferred at the access point without tunneling additional packets to the SDN controller).

摘要： A system and method can support a middleware machine environment that include one or more gateway nodes. One or more gateways that resides on the one or more gateway nodes are provided in a subnet with a plurality of host servers, wherein each host server is associated with one or more virtual network interface cards (vNICs). The middleware machine environment also include a plurality of virtual hubs (vHUB) on the one or more gateways, with each vHUB associated with one or more said vNICs. The gateways are adapted to connect with an external network, and operate to forward a multicast packet to both the external network and the plurality of host servers via the plurality of vHUBs, and prevent multicast packet traffic loops between the subnet and the external network.

摘要： A novel method for fully utilizing the multicast or broadcast capability of a physical network is provided. The method identifies segments of the network within which broadcast traffic, multicast traffic, or traffic to unknown recipients (BUM traffic) is allowed or enabled. The identified segment encompasses parts of the network that the BUM traffic is able reach while excluding parts of the network nodes that the BUM traffic is unable to reach. Each identified segment includes network nodes that are interconnected by physical network hardware that supports BUM traffic. The method identifies multiple BUM traffic segments in a given network that each supports its own BUM traffic. The different BUM traffic segments are interconnected by physical network hardware that does not support BUM network traffic. Each identified segment is assigned an identifier that uniquely distinguishes the identified segment from other identified segments.

摘要： It is determined whether a packet is a multicast packet, and an index to a database is selected from i) a first candidate index determined based on header information of the packet, or ii) a second candidate index determined based on the header information, based on whether the packet is a multicast packet. Information is retrieved from the database using the index, and the header information is compared with information retrieved from the database. Further information retrieved from the database is used to determine one or more ports via which the packet should be transmitted when the header information matches the information retrieved from the database.

摘要： A method of providing information regarding an Ethernet frame, within the Ethernet preamble of the Ethernet frame, comprises inserting into the Ethernet preamble an inter-line-card header that includes a start control character, a version number, a parity bit, a source port, a destination port, and a forwarding domain entry; and preserving said inter-line-card header, inside of said Ethernet preamble, in a Media Access Control (MAC) sub-layer in said Ethernet frame. The method may include a step of selecting the decoding format for the inter-line-card header corresponding to the version number and/or forwarding other Ethernet frames according to additional forwarding information provided by the forwarding domain entry. The inter-line-card header may be preserved in the MAC sub-layer by keeping the Ethernet preamble at the beginning of an Ethernet frame received over an Ethernet backplane, and passing the combined preamble and associated Ethernet frame to an inter-line-card header processing module.

摘要： A system for negotiating Ethernet link settings between interconnected nodes in a network having an Ethernet protocol stack that includes a PCS sub-layer with an auto-negotiation function. The system comprises connecting an intermediate device coupled between two network nodes via optical or copper interfaces, with the link settings between each node and the connected intermediate device being the same, thereby bypassing the auto-negotiation of the PCS sub-layer in the intermediate device. The intermediate device may transparently send negotiation messages from each node to the other during the link negotiation phase without interacting with those messages. Instead of the intermediate device, a single form pluggable (SFP) device may be connected between the two network nodes via optical or copper interfaces on the network side and via an SFP slot on the device side.

摘要： A system for protection switching in radio networks includes a plurality of nodes, a plurality of links of Ethernet interconnecting the nodes and forming a network, at least one wireless link interconnecting two of the nodes, and two Virtual Local Area Networks (VLAN) within the network, only the first VLAN comprising the wireless link. The network transports packets of Ethernet associated with a first Classes of Service (CoS) and a second CoS via the first VLAN. Upon detection of a reduction in performance of the wireless link, the network maps the second CoS to the second VLAN, and by that offloading traffic associated with the second CoS from the wireless link.
