    Abstract: In general, embodiments of the invention relate to processing network traffic data units (NTDUs). More specifically, embodiments of the invention relate to processing NTDUs transmitted between client device and the one or more protected resources. The protected resources are logically surrounded by a perimeter, which is implemented as a set of network devices that manage the flow of NTDUs between client devices and the protected resources. The perimeter works in conjunction with a set of filtering devices to determine whether a given NTDU can ultimately be transmitted to, and processed by, a protected resource.

    Abstract: Embodiments of the invention may relate to methods, systems, and/or non-transitory computer readable mediums for sidelining Such sidelining may include making a first determination, by a first network device, that a first network device state has degraded and making a first request, based on the first determination, to receive a first sideline token from a network controller. The network controller, in response to the first request, may make a second determination that a remaining sideline token is available. The method may also include receiving, by the first network device and based on the second determination, the remaining sideline token from the network controller and initiating, by the first network device, a graceful offlining based on receiving the remaining sideline token.

    Abstract: A method for virtual extensible local area network (VXLAN) encapsulation. The method includes receiving a first augmented MAC frame on a first ingress port of a first network device, where the first augmented MAC frame includes a first egress port ID (EPID), a first ingress port ID (IPID), and a first MAC frame. The method further includes identifying a first destination VXLAN tunnel endpoint (VTEP) internet protocol (IP) address based on the first EPID, where the first destination VTEP IP address is associated with a first destination VTEP. The method further includes identifying a source VTEP IP address based on the first IPID, performing VXLAN encapsulation of the first MAC frame to obtain a VXLAN frame, and sending the VXLAN frame to the first destination VTEP via a first egress port of the first network device.

    Abstract: A method and system for sharing host entries between virtual tunnel endpoints (VTEPs). The method includes making a first determination that an NLHE is present in a locally learned host entry table on a VTEP where the NHLE is associated with a first timestamp, and making a second determination that a first entry corresponding to the NHLE is present in a Host-Specific Portion of Global Host Entry Table (HSPT) on the VTEP, where the first entry is associated with a second timestamp. Based on the second determination, making a third determination, using the timestamps, that the NHLE is more recent than the first entry and based on the third determination updating an active forwarding table on the first VTEP to include a second entry corresponding to the NHLE and to remove the first entry and sending the NHLE to a VXLAN controller operatively connected to the VTEP.

    Abstract translation: 一种用于在虚拟隧道端点（VTEP）之间共享主机条目的方法和系统。 该方法包括首先确定NLHE存在于VTEP上的本地学习的主机条目表中，其中NHLE与第一时间戳相关联，并且进行第二确定，与NHLE相对应的第一条目存在于主机 - VTEP上的全局主机条目表（HSPT）的特定部分，其中第一个条目与第二个时间戳相关联。 基于所述第二确定，使用所述时间戳来确定所述NHLE比所述第一条目更新，并且基于所述第三确定来更新所述第一VTEP上的活动转发表以包括对应于所述NHLE的第二条目，以及 删除第一个条目并将NHLE发送到可操作地连接到VTEP的VXLAN控制器。

    Abstract: A method and apparatus of a device that notifies another device of a failed device is described. In an exemplary embodiment, a network element detects that a first device is unavailable, where the network element couples the first device to the second device. In response to detecting that the first device is unavailable, the network element configures a proxy for the first device. The network element additionally receives network data that is destined for the first device, where the second device originated the network data. If the proxy can process the network data, the network element transmits a response to the second device from the proxy, where the response indicates that the first device is unavailable, where the first response includes an address of the first device. If the proxy cannot process the network data, the network element drops the network data.
