  • Patent number: 9785787
    Abstract: A device may identify an image to be encrypted, and may convert the image to a first string in a first format. The first string may represent the image. The device may receive information that identifies a key for encrypting the first string, and may generate a first encrypted string by encrypting the first string using the key. The device may convert the first encrypted string, in the first format, to a second encrypted string in a second format. The device may provide the second encrypted string to a storage device without providing the key or the image to the storage device. The storage device may be unable to recover the image using the second encrypted string.

  • Patent number: 9787638
    Abstract: A device may receive data from a first endpoint device. The device may identify a network protocol. The network protocol may be associated with receiving the data. The device may identify a format. The format may be associated with encoding textual information in the data. The device may determine, based on the format and the network protocol, text in the data. The device may determine whether the text includes a reference from a plurality of references. The plurality of references may identify addresses associated with malicious devices. The device may selectively forward the data to a second endpoint device based on determining whether the text includes the reference.

  • Publication number: 20170289216
    Abstract: In general, techniques are described for providing Hot-Root Standby in Global Table Multicast (GTM) environments. For example, in such GTM environments, normally a single unicast route to the customer multicast source (“C-Source”) will be available to egress provider edge (PE) routers. As described herein, ingress PE routers may advertise multiple routes to a C-Source, including unicast routes that include Route Import Extended Communities, which are imported by egress PE routers. This enables an egress PE router to have multiple paths to the C-Source, and the egress PE router may generate multiple C-multicast source tree joins for respective ingress PE routers in order to receive respective multicast streams sourced by the C-Source from the ingress PE routers.

  • Patent number: 9778944
    Abstract: A device may receive an indication to perform a reboot associated with a network service provided via a first virtual machine (VM) of the device and a first container of the device. The device may create a second VM with a boot mode enabled and a second container with the boot mode enabled. The boot mode, while enabled on the second VM, may prevent the second VM from communicating with the first container. The boot mode, while enabled on the second container, may prevent the second container from communicating with the first VM. The device may shut down the first container. The device may disable, after shutting down the first container, the boot mode on the second VM. The device may disable the boot mode on the second container. The device may cause the network service to be provided by the second container and the second VM.

  • Patent number: 9781058
    Abstract: In general, techniques are described to dynamically adjust a session detection time defined by a timer in accordance with a bidirectional forwarding detection (BFD) protocol. The techniques utilize existing hardware and BFD software infrastructure. An example network device includes a memory, programmable processor(s), and a control unit configured to execute a timer, receive one or more packets provided by the BFD protocol, detect, based on the received one or more packets, a congestion condition associated with a link via which the network device is coupled to a network, adjust, based on the detected congestion condition, a session detection time defined by the timer, and in response to a failure to receive a packet provided by the BFD protocol within the session detection time defined by the timer, detect a failure associated with the link.

  • Patent number: 9779271
    Abstract: The disclosed apparatus may include a secure storage device that securely stores an initial geographic location of a network device that facilitates network traffic within a network. This apparatus may also include a processing unit communicatively coupled to the secure storage device. The processing unit may determine a current geographic location of the network device. The policy-enforcement unit may then detect evidence of theft of the network device by (1) comparing the current geographic location of the network device with the initial geographic location of the network device and (2) determining, based at least in part on the comparison, that the current geographic location of the network device does not match the initial geographic location of the network device. Finally, the processing unit may perform at least one security action in response to detecting the evidence of theft of the network device.

  • Patent number: 9781032
    Abstract: In general, techniques are described for configuring a provider edge (PE) network device of an Ethernet virtual private network (EVPN) to use a common traffic engineering label (e.g., MPLS label) for different EVPN route types associated with the same EVPN. In some examples, the techniques include sending a first layer three (L3) control plane message that indicates a label-switched network protocol label that corresponds to a first EVPN route type, wherein the first L3 control plane message indicates that a first PE network device is reachable in the L2 segment. The techniques may include performing L2 address learning to determine at least one L2 address associated with the layer two segment of the EVPN. The techniques may include sending a second L3 control plane message that indicates the same label included in the first L3 control plane message corresponds to a second EVPN route type.

  • Patent number: 9781030
    Abstract: Techniques are described for providing fast re-route (FRR) node and/or link protection along a primary label switched path (LSP) using generic routing encapsulation (GRE) over multi-protocol label switching (MPLS). An ingress edge router of a primary LSP is configured to encapsulate incoming packets into GRE with a destination address of an egress edge router of the primary LSP, and push a primary label onto the encapsulated packet for forwarding along the primary LSP. Upon a failover to a bypass LSP, a point of local repair (PLR) router swaps the primary label on the encapsulated packet with a bypass label. A merge point (MP) router then receives the encapsulated packet via the bypass LSP, and performs a lookup using the destination address of the egress edge router included on the encapsulated packet in order to determine a primary label for forwarding the encapsulated packet along the primary LSP.
