A system for managing access point functionally and configuration includes a server that is coupled to a computer network and configured to communicate with an access point via the computer network. The access point is configured to couple a mobile device to the computer network by providing a wireless link between the mobile device and the access point. The access point is further configured to produce a status point regarding the access point and the server is configured to receive the status report from the access point following a trigger event at the access point. In other examples, the server is further configured to transmit a response message and/or a configuration file to the access point in response to the status report that is received at the server. Other features and systems are also disclosed.

A multi-chip module (MCM) may include a substrate, and first and second physical-layer (PHY) chips mounted on the substrate. In some implementations, the first PHY chip includes a multiplexer and a PHY circuit. The multiplexer is configured to receive a multiplexed data stream from a media access control (MAC) device, to demultiplex the multiplexed data stream into first and second data streams, to output the first data stream to the PHY circuit, and to output the second data stream to the second PHY chip. In some implementations, the first PHY includes a router and a PHY circuit. The router is configured to receive a plurality of data packets from a MAC device, to route one or more of the data packets having a first address to the PHY circuit, and to route one or more of the data packets having a second address to the second PHY chip.

Various exemplary embodiments relate to a method for processing data packets by a first-hop switch in a data network, including: receiving a first data packet associated with a flow; determining whether the flow associated with the first data packet is found in a flow table in the first-hop switch; modifying the first data packet by replacing a packet header field with flow definition information; and transmitting the modified first data packet based upon the flow definition information.

The communication node includes an entry memory adapted to store a preset number of the control information entries, each stipulating the processing applied to a packet received, in association with the user information, and a packet processor that references the entry memory to process the packet received. The communication node also includes an entry management section that exercises control so that, on the basis of a preset reference, the proportion of the number of the control information entries for one user stored in the entry memory to the number of the control information entries storable in the entry memory will not surpass a preset value.

A packet processing method and a background server are provided. The packet processing method includes: receiving, by a bearer system of a background server, an IPIP packet sent by an access server via an IP tunnel; and removing a reverse proxy IP address and a windows server IP address that are in an outer layer of the IPIP packet, and changing a destination IP address in the IPIP packet, of which the reverse proxy IP address and the windows server IP address are removed, into the windows server IP address, to obtain an IP packet.

An example method includes exchanging targeted hello messages to establish a targeted neighbor connection between a first routing device and a second routing device, wherein one of the routing devices comprises a central routing device, and wherein another one of the routing devices comprises an ingress routing device. The example method further includes processing a source-active register message that specifies a source address and an identifier that are collectively associated with a multicast stream, and wherein the source-active register message further indicates whether the multicast stream is active or withdrawn. After processing the source-active register message, the example method further includes processing a list-of-receivers register message that specifies an egress routing device and at least the identifier that is associated with the multicast stream, wherein the list-of-receivers register message further indicates whether or not the egress routing device requests receipt of data associated with the multicast stream.

The present invention enables packet data to be filtered without distinguishing between non-fragmented packets and fragmented packets. This invention is characterized in that: when received packet data is a fragmented packet but is not a lead fragmented packet, header information of the lead fragmented packet, which has the same fragmented packet identification information as that of the packet data, is given to the packet data as a pseudo-header; the header information of the packet data is used as a key and a filter table is searched in which a filter condition about the header information corresponds to a process implemented when the filter condition is satisfied; the process corresponding to the filter condition satisfied by the header information of the packet data is determined as a process performed for the packet data; and the determined process is performed on the packet data.

One or more techniques and/or systems are provided for network isolation. For example, nodes within a mesh of devices may be configured with routing rules, main routing tables, and alternative routing tables, such as at a layer-3 network layer. The routing rules may specify that packets received from downstream are to be routed upstream to either a gateway or a backhaul device for evaluation as to whether such packets are allowed to be communicated back downstream to destination recipients using main routing tables. An isolation rule may be configured to specify whether to block or allow packets. In an example, the gateway may either block or allow packets based upon whether a source and destination are within a same virtual local area network or are within different virtual local area networks. In this way, selective device isolation may be provided, such as at the layer-3 network layer.

Methods, systems, and computer programs are presented for managing a network in the presence of layer-2 loops. One method includes an operation for detecting, by a network device, a loop at a layer 2 of a network. The network device is configured to execute a network device operation system (ndOS), where network devices executing ndOS share a global switch table. The method further includes an operation for blocking ports associated with the loop where incoming packets received at the blocked ports are discarded except for loop-probe packets. Further, the method includes operations for sending loop-probe packets by one or more network devices executing ndOS through one or more ports, and for unblocking a first port of the blocked ports based on the loop-probe packets when a lack of receipt of a loop-probe packet within a predetermined amount of time is detected for the first blocked port which indicates that the first blocked port is not part of the loop.

The present disclosure illustrates a routing system with learning functions and a routing method thereof. By detecting a raw packet's packet header and an entry port receiving the raw packet, a routing message is queried from a path table by the packet header and the entry port. When there is not the routing message, the raw packet is routed by a kernel and the routing result is recorded in the path table to be the routing message. When there is the routing message, the packet header of the raw packet is replaced with a modified packet header recorded in the routing message, to form a modified packet, and the modified packet is transmitted from the transmission port recorded in the routing message, to achieve the technical effect of improving the routing performance for the packets with the same packet headers and the same entry ports.
