One embodiment of the present invention provides a switch. The switch includes a local identifier associated with the switch, a receiving interface, a loop detection mechanism, and an interface control mechanism. The receiving interface identifies a loop-detection frame which includes an identifier associated with originating switch of the frame. The loop detection mechanism detects a loop based on a match of the identifier associated with the originating switch and the local identifier. The interface control mechanism is coupled to the loop detection mechanism and precludes, in response to detecting a loop, the receiving interface from forwarding frames corresponding to the loop.

One embodiment of the present invention provides a switch. The switch includes a local database, a packet processor, a data management module, and a tree construction module. The packet processor extracts spanning tree information associated with a remote switch. The data management module stores the extracted spanning tree information in the local database. The tree construction module assigns an interface state associated with a spanning tree to a local interface based on the extracted spanning tree information.

One embodiment of the present invention provides a switch. The switch includes an ownership management mechanism and a notification mechanism. The ownership management mechanism maintains a local ownership association between the switch, and a medium access control (MAC) address learned at the switch and terminates the local ownership association for the MAC address. The notification mechanism generates a first notification indicating the local ownership association and a second notification indicating the termination of the local ownership association.

One embodiment of the present invention provides a switch. The switch includes a notification mechanism. The notification mechanism constructs a single message that contains a locally learned MAC address associated with a local device, a TRILL RBridge identifier associated with the switch, and an identifier of an interface associated with the MAC address. In some embodiments, the switch includes a data structure and an entry management mechanism. The data structure stores device information learned at a remote switch, wherein the device information includes a MAC address of a device, a TRILL RBridge identifier associated with the remote switch, an identifier of an interface coupled to the device, and a type indicator of the MAC address. The entry management mechanism manages an entry in the data structure based on the RBridge identifier and the interface identifier.

One embodiment of the present invention provides a switch. The switch includes a storage and a lookup mechanism. The storage stores a first table that contains an entry corresponding to a media access control (MAC) address of a device and an identifier of a remote switch associated with the device. The storage also stores a second table that contains an entry indicating a local outgoing interface corresponding to the remote switch. The lookup mechanism identifies the local outgoing interface corresponding to the device based on the first table and the second table.

One embodiment of the present invention provides a computing system. The computing system includes a packet processor, a buffer management module, a data monitoring module, and a flow control module. The packet processor identifies a class of service indicating priority-based flow control associated with a remote computing system from a notification message. The buffer management module creates a buffer dedicated for frames belonging to the class of service from the remote computing system in response to identifying the class of service. The data monitoring module detects a potential overflow of the buffer. The flow control module operates in conjunction with the packet processor to generate a pause frame in response to detecting a potential overflow.

Systems and techniques for supporting multiple multicast trees are described. Some embodiments provide a system that determines an internal multicast group identifier based on a source address, a multicast address, and a multicast tree identifier field associated with a multicast packet. The system can then forward the multicast packet based on the internal multicast group identifier. Specifically, the system can determine a first set of bits based on the source address and the multicast address of the multicast packet. The system can determine a second set of bits based on the multicast tree identifier field of the multicast packet. Next, the system can combine the first set of bits and the second set of bits to obtain the internal multicast group identifier. In some embodiments, the scope of an internal virtual network identifier does not extend beyond a switch or a forwarding module within a switch.

Systems and techniques for processing and forwarding packets are described. Some embodiments provide a system (e.g., a switch) which determines an internal virtual network identifier and/or an internal policy identifier for a packet based on a port on which the packet was received and/or one or more fields in the packet. The system can then process and forward the packet based on the internal virtual network identifier and/or internal policy identifier. In some embodiments, the system encapsulates the packet in a TRILL (Transparent Interconnection of Lots of Links) packet by adding a TRILL header to the packet. In some embodiments, the scope of an internal virtual network identifier and/or an internal policy identifier may not extend beyond a switch or a module within a switch.
