摘要： An endpoint for determining a frame loss ratio is provided. The endpoint includes a processor and a memory coupled with the processor. The memory stores instructions that are executable to generate a number of synthetic frames, and insert the number of synthetic frames into a stream of data frames, the synthetic frames being transmitted to a responder endpoint address designated in the synthetic frames. The memory may also store instructions that are executable to determine a number of lost synthetic frames; and calculate a synthetic frame loss ratio as a function of the number of lost synthetic frames and the number of synthetic frames inserted into the stream of data frames.

摘要： Various systems and methods for preventing loops in the presence of control plane failures are disclosed. For example, one method involves sending a special data packet in response to detection of a break in a network loop and then unblocking a port if the special data packet fails to circumnavigate the network loop. Prior to detection of the break, the port was blocked by a loop prevention protocol, such as a spanning tree protocol. If the special data packet successfully circumnavigates the network loop, the port will not be unblocked.

摘要： A method is provided in one example embodiment and includes generating a test port in a network environment, positioning the test port on a network element, associating the test port with a bridge domain, and configuring a maintenance point (MP) on the test port. The method further includes using the MP on the test port for connectivity fault management (CFM) operations at a test level.

摘要： Various systems and methods for implementing virtual ports within ring networks are disclosed. For example, one method involves allocating a logical port that corresponds to a first port and a second port and instantiating a spanning tree protocol instance. The first port and the second port are both assigned to a first ring network. The spanning tree protocol instance selectively blocks the logical port; however, the spanning tree protocol instance is unable to block the first port independently of blocking the second port. Events (e.g., link failures and recoveries) that occur within the ring network are communicated to spanning tree by transitioning the state of the logical port in response to receiving a ring protocol control packet. The spanning tree protocol instance initiates a bridge protocol data unit (BPDU) exchange from the logical port in response to a transition in the state of the logical port.

摘要： Various systems and methods for integrating ring-protocol-compatible devices into network configurations that also include non-ring-protocol-compatible devices are disclosed. One such method, which can be performed by a network node that supports a ring protocol, involves generating a ring protocol packet and sending that ring protocol packet to a neighboring node. The ring protocol packet includes information, and the presence of this information within the packet causes a network device that receives the ring protocol packet to drop the ring protocol packet unless the network device supports a ring protocol. The information can include a reserved address (e.g., in the destination address field of the packet) as well as a ring protocol identifier.

摘要： Methods and systems for distributing multicast messages in a network are disclosed. The use of such a method or system in an Ethernet network can result in a reduction in the number of flooded multicast messages. One method can involve receiving a companion message, which includes a multicast address, at a network device and extracting the multicast address from the companion message. The multicast address can then be associated with a VLAN and an interface of the network device. Another method involves receiving a join message, which identifies a multicast group being joined, and generating a companion message corresponding to the join message. The companion message includes an address of the multicast group.
