Abstract: In an example embodiment, packets for a selected flow are replicated and sent over one or more diverse paths, such as a primary path and at least one secondary path, to a destination switching device. At the destination switching device, one copy of the replicated packets is selected for delivery to the destination, and the remaining copies are discarded. In the event that packets are not received at the destination switching device due to loss of connection on the primary path or packets are not timely delivered due to congestion on the primary path, a different path may be selected as the primary path.

Abstract translation: 在示例实施例中，用于所选流的分组被复制并通过一个或多个不同路径（诸如主路径和至少一个次要路径）发送到目的地交换设备。 在目的地交换设备处，选择复制的分组的一个副本以传送到目的地，并且剩余的副本被丢弃。 如果由于主路径上的连接丢失而在目的地交换设备处没有接收到分组，否则由于主路径上的拥塞而不能及时地传送分组，可以选择不同的路径作为主要路径。

Abstract: Techniques are provided to enable a support for guest access of devices in a network. At a controller apparatus in a first mobility sub-domain of a network comprising a plurality of mobility sub-domains, a request message containing a request for guest network access for a device is received from a first access switch in the first mobility sub-domain. The controller apparatus forwards the request message to a guest controller. At a tunneling endpoint apparatus in the first mobility sub-domain, a tunnel is established to the guest controller to carry traffic between the device and the guest controller. Traffic for the device passes in a tunnel between the first access switch and the tunneling endpoint apparatus in the first mobility sub-domain, through the tunneling endpoint apparatus in the first mobility sub-domain and in the tunnel between the routing apparatus in the first mobility sub-domain and the guest controller.

Abstract: Techniques are provided for seamless integration of wired and wireless functionality packet forwarding in network. A plurality of access switches are provided in each of a plurality of mobility sub-domains that are part of a mobility domain of a network. Each access switch serves one or more Internet Protocol (IP) subnets, each comprising a plurality of IP addresses. An access switch obtains an IP address for a wireless device according to the one or more IP subnets that the access switch serves. The access switch sends an association advertisement message to indicate the IP address of the wireless device and to enable other access switches and routers to compute a path to the wireless device. When a wireless device obtains an IP address, it can keep the same IP address as it roams in the mobility domain.
