Abstract: Systems, methods, and computer-readable media for implementing zero-configuration networking over a wide area network. Disclosed are systems, methods, and computer-readable storage media for implementing zero-configuration networking over a wire area network by utilizing agents, application programming interfaces (API), and a controller. The controller can implement polices for communication between the agents and APIs, enabling zero-configuration network

Abstract: Systems, methods, and computer-readable media for implementing local and wide network suppression of query requests in zero-configuration networking. Disclosed are systems, methods, and computer-readable storage media for implementing suppression of query packets zero-configuration networking over local and wide networks by utilizing agents, application programming interfaces (API), and a controller. The suppression can be determined based on two time periods, a processing period and a suppression period.

Abstract: Systems, methods, and non-transitory computer-readable storage media for recovering from a partial failure of a virtual port chain (vPC) domain. The first and second vPC peers may be paired to create a vPC having a virtual address. An endpoint host may communicate with a network via the virtual port channel. The system may detect that the first virtual port channel peer is down. During or after the first vPC reboots, the reachability cost for the first vPC with regards to the virtual address can be set to an inflated value. The first vPC peer may also delay its bring up time while it synchronizes its vPC state information with the second vPC peer. The second vPC can continue to advertise the association between the endpoint host and the virtual address. Upon completion of the synchronization, the first vPC peer may bring up the link and restore the reachability cost.

Abstract translation: 用于从虚拟端口链（vPC）域的部分故障中恢复的系统，方法和非暂时的计算机可读存储介质。 第一和第二vPC对等体可以被配对以创建具有虚拟地址的vPC。 端点主机可以通过虚拟端口信道与网络进行通信。 系统可以检测到第一个虚拟端口信道对等体已经关闭。 在第一个vPC重新启动期间或之后，第一个vPC关于虚拟地址的可达性成本可以被设置为一个膨胀的值。 第一个vPC对等体也可以延迟其启动时间，同时将其vPC状态信息与第二个vPC对等体同步。 第二个vPC可以继续通告端点主机和虚拟地址之间的关联。 完成同步后，第一个vPC对等体可能会弹出链接并恢复可达性成本。
