摘要： To send a connection control message associated with a first set of attributes, only a difference of the first set of attributes from a second set of attributes associated with an already active virtual circuit (to a common destination) may be sent (contained in the connection control message). The devices receiving the message may create the necessary configuration for the new virtual circuit by modifying a copy of the configuration of the active virtual circuit. Processing requirements may be minimized as the devices may not need to parse and decode long list of information element. The feature may be particularly important in setting up a virtual circuit for voice calls, as a long list of attributes may be associated with each virtual circuit, but the difference of attributes being only minimal.

摘要： Moving a virtual circuit from one port interface to another when multiple port interfaces are present between two network devices. Such a move may be performed, for example, when a port interface fails or when needed to balance the load (e.g., aggregate amount of bandwidth of all virtual circuits presently assigned to a port interface) across multiple port interfaces. As a result, the port interfaces may be used efficiently.

摘要： The services offered (e.g., bandwidth) by a PVC can be changed, potentially as and when desired. An end system (of a PVC) may send a request to initiate a change of a service. Each intermediate system may first determine whether the service change can be supported, and passes the request to the next system in the path until the request is received by the other end system of the PVC. Assuming the other end system also can support the change, an acceptance response is propagated in the reverse direction of the same path. Each system may effect the service change upon receiving the acceptance response.
摘要翻译：由PVC提供的服务（例如，带宽）可以根据需要进行改变。一个PVC的终端系统可以发送一个请求来启动服务的更改。每个中间系统可以首先确定是否可以支持服务改变，并且将该请求传递到路径中的下一个系统，直到PVC的另一端系统接收到该请求。假设另一端系统也可以支持改变，则接收响应在相同路径的相反方向上传播。每个系统可能在接收到接受响应后影响服务改变。

摘要： An end system (“first end system”) concluding that a bi-directional virtual circuit is operational if the other end system (at the other end of the virtual circuit) has determined that the virtual circuit is operable based on the loopback cells. In other words, the first end system may not send loopback cells, and instead rely on the determination of the other end system. As a result, the total number of loopback cells may be reduced on a network backbone.

As a result, high aggregate effective bandwidth can be provided between edge routers, potentially without having to use a correspondingly high bandwidth physical connections.

摘要： In one embodiment, a device receives a first packet stream and a second packet stream over different paths through a network, wherein each of said sent first and the second packet streams includes a same replicated stream of packets. The apparatus processes packets of the first packet stream when the first packet stream is in an active packet stream, and while buffering and subsequently dropping packets of the second packet stream when the second packet stream is in a non-active state. In response to identifying a difference in a number of packets in the same replicated stream of packets received in the second packet stream compared to in the first packet stream equaling or exceeding a predetermined threshold, the second packet stream becomes in the active state and missing packets are forwarded from the buffered second stream packets.

摘要： Systems, methods, and other embodiments associated with layer two (L2) encryption for data center interconnectivity are described. One example system includes a receive logic to receive an unencrypted L2 switched frame (UL2SF). The UL2SF may include a payload and an L2 header. The example system may also include an encryption logic to selectively encrypt the UL2SF into an encrypted frame if the UL2SF is to be sent through an L2 virtual private network (L2VPN) requiring encryption. The example system may also include a delivery logic that adds a header to the encrypted frame. The header may include data to identify a decryption function to decrypt the encrypted frame and routing information for the encrypted frame. The delivery logic may also provide the encrypted frame to the L2VPN, where the providing includes selectively sending the encrypted frame as one of, a point to point packet, and a multipoint packet.
