摘要： The following description is directed to encrypting the characteristics of network traffic. In one example, a method can include receiving an unencrypted link layer packet including a first payload of a first size. The method can include encrypting the first payload of the unencrypted link layer packet. The method can include generating an encrypted link layer packet including a second payload. The second payload can include the encrypted payload and a variable length padding field so that the second payload of the encrypted link layer packet is a different size than the first size of the first payload. The encrypted link layer packet can then be transmitted.

摘要： Technologies are provided for organizing network routes using network topology information. A router in a computer network can be configured to group network address prefixes in a routing table based on origin device clusters. The router can be configured to receive a routing protocol message comprising one or more prefixes and associated next hops. The router can identify an origin device cluster based on information contained in the message. The router can create a next hop group and associate it with the origin device cluster. The router can add the prefixes and next hops in the message to the next hop group. When an updated next hop list for a prefix is received at the router, the router can identify an origin device cluster for the prefix, identify a next hop group associated with the origin device cluster, and update the next hop group using the updated next hop list.

摘要： Communication systems include network nodes that distribute an electrical or optical base signal to remote nodes for modulation at the remotes nodes. A first waveguide is coupled to transmit data to a corresponding remote node, a second waveguide is coupled to receive remotely modulated data from the remote node, and a third waveguide is coupled to deliver the base signal to the remote node. Typically, the base signal is an optical signal from a laser diode, and optical fibers communicate modulated data signals and the base signal. A portion of the base signal can also be modulated for communication with remote nodes.

摘要： A modular encryption device includes a chassis configured to mount in a rack with a networking device and sets of ports mounted on the chassis. Encryption cards are mounted in the chassis of the modular encryption device between ports of the sets of ports such that network traffic flowing through a set of ports flows through one of the encryption cards. The encryption cards of the modular encryption device are configured to encrypt and decrypt network traffic flowing between the networking device and a remote device. In some embodiments, a modular encryption device may encrypt and decrypt network traffic flowing between multiple networking devices and multiple remote devices. Also, in some embodiments, components of a modular encryption device are removable and replaceable such that the modular encryption device can be reconfigured by exchanging the components.

摘要： Systems and methods for the management of virtual machine instances are provided. The hosted virtual machine networks are configured in a manner such that communications within the hosted virtual machine network are facilitated through a communication protocol. Illustrative embodiments of the systems and methods may be implemented on a virtual network overlaid on one or more intermediate physical networks that are used as a substrate network. Through the utilization of one or more virtual network mapping components in communication with the hosted virtual network components, communications to and from the hosted virtual networks can be processed by mapping relationships between the virtual network communication protocol and the router communication protocol. The mapping information can be provided in advance or as requested to the router components and hosted virtual network components to facilitate bi-lateral communications between the components.

摘要： A network switch and system for detecting the capacity of available paths in a network and for modifying traffic distribution at each stage of the network, such that traffic is proportionally balanced across the unequal capacity paths. A centralized controller manipulates path weights on each switch such that a load is distributed proportionately to the capacity available to ensure that all available capacity is evenly utilized. A central view of the network is used to determine capacity information, calculate a minimal change set to optimize the traffic flows, and modify the existing multipath group objects. A centralized application can use the capacity information of each switch to build a capacity model of the network. Once the full model has been built up by the application, programming of the specific decisions is done via the controller through an API in communication with each network device's local agent.

摘要： Disclosed are various embodiments for performing network traffic redirection at the client side. Sending of data to a service at a network address is initiated. Whether the network address is in a predetermined network address range is determined. The network address is translated, when the network address is in the predetermined network address range, to one of multiple other network addresses based at least in part on an availability of the service at the other network address. The data is routed to the other network address.

摘要： A dynamic configuration system can manage and configure switches or other network devices that come online in a network. When the dynamic configuration system determines that a network device has come online, the dynamic configuration system can identify the network device (e.g., based on its network location, neighbors, fingerprint, identifier, address or the like), select the appropriate configuration data for the network based on the desired network topology, and transmit the configuration data to the network device. The network device can then load the configuration data and function as a component of the desired network topology.
