A method for visualizing a network. The method includes identifying, for each of a set of network elements, a network element role and a network element connectivity, grouping the network elements based on the network element roles, displaying at least a subset of the grouped network elements, and displaying connections between the displayed network elements, based on the network element connectivity.

In general, embodiments of the invention relate to a method and system for presenting container tracing information (CTI). More specifically, CTI represents the union of container-server mappings, provided by a third-party container management system (CMS), and server-port mappings obtained by a network element using neighbor information. As a solution, CTI may be useful to administrators who require locating containers in a network or datacenter for troubleshooting.

Methods, systems, and devices for managing communications in a distributed system are disclosed. To improve the efficiency of communication, the system may implement the port extension protocol which may allow communication devices to utilize ports of other devices for communication purposes. To do so, the communication devices may instruct the other devices with respect to how the communication devices expect the other devices to process data units transmitted via networks (e.g., network data units). However, not all of the other devices that may process the network data units may include functionality to process and/or implement the instructions from the communication devices. To extend the functionality of such devices, a remote control plane for devices that lack this processing functionality may be provided.

A communication system includes: a control apparatus configured to set control information, which causes each control target switch to distinguish a link layer discovery protocol packet of a first network from a link layer discovery protocol packet of a second network different from the first network and to perform corresponding predetermined processing, in each control target switch; a group of switches each of which is configured to transmit a link layer discovery protocol packet of the first network to a predetermined topology management apparatus in accordance with control information set by the control apparatus; and a topology management apparatus configured to manage a network topology configured by the group of switches on the basis of information included in a link layer discovery protocol packet of the first network received from each of the switches.

Some examples provide a method for automatic network assembly. The following instructions may be used to implement automatic network assembly in a modular infrastructure. Instructions to automatically connect a management port to a management network. Instructions to automatically connect link ports to form a scalable ring. Instructions to automatically connect each modular infrastructure management device to a bay management network port.

Embodiments of the present invention provide a data processing method and apparatus. The method includes: receiving a data packet sent by a server, and acquiring a type of the data packet; determining whether the type of the data packet is consistent with a type of a data packet processed by using a preset processing rule or a type of a protocol in a preset TCP/IP protocol stack to obtain a determining result; and if the type of the data packet is consistent with the type of the data packet processed by using the preset processing rule or the type of the protocol in the preset TCP/IP protocol stack, performing processing on the data packet according to the protocol in the preset TCP/IP protocol stack or the preset processing rule.

A Compact computing device with peer-to-peer communication through an Ethernet interface is provided. According to one embodiment, a compact computing device includes an Ethernet interface, an Ethernet discovery agent, a memory and a micro-controller. The Ethernet interface is capable of connecting to a host though an Ethernet link. One side wall of the compact shielding case accommodates only the Ethernet interface. The Ethernet discovery agent is capable of discovering the host to which the compact computing device is connected. The memory is capable of storing information that is to be transferred to the host or information that is received from the host. The micro-controller is capable of exchanging information with the host through the Ethernet link.

This application relates to the field of logistics, and discloses a data reporting method and system for logistics containers. Each logistics container is provided with a terminal, and the terminal includes a first communication module and a second communication module. The server sends a first message to the second communication module of the first terminal; when the second terminal communicates with the server through its second communication module, it reports the identification of other surrounding terminals detected by the second terminal through its first communication module to the server; if the server detects that the reported identifier includes the identifier of the first terminal, it sends a second message to the second terminal; In response to the second message, the second terminal wakes up the second communication module of the first terminal through its first communication module; The first terminal communicates with the server through its second communication module, and receives the first message. This application can realize the timely and on-demand reporting of data to the server by the logistics container under the condition of low power consumption, which reduces the labor cost and material cost of the management of the logistics container.

An OFS in-band communication method and an OFS are disclosed. The method includes: receiving an LLDP data packet; creating a controller list entry or updating a controller list entry when it is determined, by using a role sub-field, that a sender type of the received LLDP data packet is OFC; acquiring a first-time TCP handshake packet used for establishing a TCP connection, and checking, according to a destination MAC and a destination IP that are carried in the TCP handshake packet, whether a corresponding controller list entry exists in a controller list; and if yes, updating a flow entry according to the MAC, the IP, and the in_port in the corresponding controller list entry in the controller list, so that an OFS can forward, by using a flow table, a packet to be sent to an OFC to the OFC.

Disclosed are application-aware packet transmission methods and apparatuses for a terminal. The application-aware packet transmission method comprises classifying applications according to delay sensitivities of the applications, determining a transmission pattern of packets for the classified applications; and transmitting the packets based on the determined transmission pattern. Thus, a battery of the terminal may be efficiently managed by applying user preferences and configuring transmission patterns of packets to be transmitted for each application differently. In addition, degradation of application performances and user experiences for the uses of applications can be prevented.
