According to an embodiment of the inventive concept, a data management device of a distributed antenna system includes an unpackaging unit, when a package file which is generated by packaging firmware files of a plurality of devices constituting a distributed antenna system is input, configured to unpackage the package file; a control unit configured to determine a device requiring firmware update by comparing version information of the package file with version information of a firmware file of each of the devices included in the unpackaged package file; and a transmission unit configured to transmit a latest version of a firmware file to a device corresponding to a top node of the device requiring firmware update according to a result of the determination.

In one embodiment, a device in a network receives a path computation agent configured to determine a path in the network that satisfies an objective function. The device executes the path computation agent to update state information regarding the network maintained by the path computation agent. The device selects a neighbor of the device in the network to execute the path computation agent based on the updated state information regarding the network. The device instructs the selected neighbor to execute the path computation agent with the updated state information regarding the network. The device unloads the path computation agent from the device after selecting the neighbor of the device to execute the path computation agent.

This application provides a method for obtaining a FIB of a device on a network. The network includes a verification system and a plurality of devices, and a first device is one of the plurality of devices. The first device receives a request message sent by the verification system, where the request message carries a command for obtaining a FIB of the first device that is generated at a specified time. The first device obtains the FIB or a FIB snapshot of the first device that is generated at the specified time. The first device adds the obtained FIB or FIB snapshot to a response message, and sends the response message to the verification system.

A hybrid configuration engine and associated method for reducing the complexity and burden of configuring rich coexistence between an on-premise solution and a cloud-based solution is described herein and illustrated in the accompanying figures. The hybrid configuration engine determines the current state of the on-premise solution and the cloud-based solution and learns the desired configuration state. After obtaining the current and desired configuration state information, the hybrid configuration engine determines and automatically performs steps to reach the desired configuration state. Finally, the hybrid configuration engine provides instructions describing the manual steps needed to reach the desired configuration state.

A system and method is provided for timely and uniform real-time data packet transmission by a computing device. The system can include a shared packet memory buffer for storing data packets generated by a user application and a shared schedule memory buffer for storing packet identifiers and corresponding time slots for the data packets. Moreover, a kernel module is provided that operates in the kernel mode of the operating system directly above the network interface controller and can continuously poll the shared scheduled memory to access packet identifiers at corresponding time slots. Based on the packet identifiers in each time slot, the kernel module can pull the data packet having the packet identifier directly from the ring buffer and send each packet to the network interface controller for transmission as part of a media stream over a network to a media consuming device.

According to one aspect disclosed herein, a system can include a set of node peers, including a first subset implemented in software and a second subset implemented in hardware. The first subset can include a software node. The second subset can include a hardware node that includes a hardware cache, a processor, and a memory that stores computer-executable instructions. The hardware node can receive, from a network, a packet, and can determine if data that identifies a path associated with the packet is stored in the hardware cache. If not, the hardware node can query the software node to identify the path associated with the packet, and can receive, in response from the software node, the data that identifies the path, which then can be stored in the hardware cache. The hardware node can forward, along the path, the packet to a network element.

A programmable device for data flow processing in a user-configurable server with swappable pods or cards is provided. The device includes a field programmable logic device (PLD) having a first region and a second region. The first region comprises a hardware-based or firmware-based router with a port enabling communication between the router and the second region, and the second region comprises one or more sandboxes with user-definable electronic circuits.

In one example embodiment, a network management device obtains a definition of a first network packet header, an identification of a condition indicating that a network packet has the first network packet header, and a definition of processing action information that includes a key and a processing action to be taken on the network packet when metadata in the network packet matches the key. The network management device merges custom network packet processing instructions written in a data plane programming language with pre-existing network packet processing instructions written in the data plane programming language to produce merged network packet processing instructions written in the data plane programming language. The custom network packet processing instructions define the first network packet header, identify the condition, and define the processing action information. The network management device provides the merged network packet processing instructions for execution by a network node.

In one embodiment, an apparatus includes a buffer memory, at least one ingress port, at least one egress port, at least one processor, and logic integrated with and/or executable by the at least one processor, the logic being configured to communicate with a software-defined network (SDN) controller, store one or more look-up tables in a first portion of the buffer memory, receive a packet using an ingress port, and determine an egress port for the packet. In another embodiment, a method for switching packets in a SDN includes storing one or more look-up tables in a first portion of a buffer memory of a SDN-capable switching device, receiving a packet using an ingress port of the switching device, and determining an egress port for the packet.

Methods for segment routing in a software-defined networking (SDN) system are disclosed. In one embodiment, a method includes receiving a plurality of values of maximum segment identifier (SID) depths, each from one network element of the SDN system, and identifying a path for a packet to transmit through a plurality of network elements, where a plurality of SIDs corresponding to the plurality of network elements is ordered to represent the path. The method further includes splitting the path into a plurality of sub-paths based on the values of the maximum SID depths of the plurality of network elements, where each network element, for the path, is allocated to process a number of ordered SIDs, and where the number is within the network element's maximum SID depth, and causing packet forwarding of the packet along the plurality of sub-paths based on SIDs allocated to the network elements.
