In various embodiments, the port forwarding processor may be configured to determine a destination port associated with a received packet. In one embodiment, the queue controller may be configured to define at least one emulated local area network (ELAN) via a respective service member set that identifies which ports are members of the service member set, determine whether or not the destination port is a permitted member of the service member set, and, if the destination port associated with the received packet is not a permitted member of the service member set, flood the received packet to the permitted members of the service member set. | 2010-02-18 |
20100040061 | MPLS TRANSPORT NETWORK SCHEME - A method of partitioning the header stack of a data packet, said header stack conforming to a label switching protocol and comprising a plurality of headers each of which comprises a label field to which a label value is assignable to enable a label switching node to route said packet in a network routing domain of label switching protocol in a communications system comprising a plurality of networks, the method comprising the steps of: receiving said packet at an edge node of a routing domain in said communications system; and processing the label header stack at the edge node to add a new stack entry having a label field comprising a value which delimits the header stack entries between a stack domain configurable by said node belonging to a first routing domain of said label switching protocol and at least one other stack domain configurable by a node belonging to another routing domain of said communications system, whereby a MPLS transport network scheme can be implemented. | 2010-02-18 |

20100040063 | GENERALIZED SERIALIZATION QUEUE FRAMEWORK FOR PROTOCOL PROCESSING - A method for processing packets. The method includes receiving a first packet, wherein the first packet is associated with a first protocol, classifying the first packet using a protocol associated with the first packet, sending the first packet to a first receive ring based on the classification, sending the first packet from the first receive ring to a first virtual network interface card (VNIC) based on an operating mode, sending the first packet from the first VNIC to a first protocol specific virtual network stack (VNS), wherein the first protocol specific VNS is configured to only process packets associated with the first protocol, and processing the first packet by the first protocol specific VNS to obtain a first processed packet. | 2010-02-18 |
