A single- or multi-protocol buffering proxy accepts communication option negotiation commands from a client before establishing a connection between the client and a host. The proxy negotiates a limited set of options with the client before the connection is established and buffers (accepts and temporarily stores without responding to) other option negotiation commands from the client. The proxy accepts credentials from a user and establishes, or denies the connection based on the credentials. If the connection is established, the proxy buffers option negotiation commands sent by the host. After the proxy logs in to the host on behalf of the user or the user logs in directly, the proxy sends each party's buffered option negotiation commands to the other party, ceases buffering option negotiation commands and enters a “pass-through” mode, in which the proxy passes characters and commands between the parties until the session ends. The proxy uses the credentials to allow or deny subsequent connection requests, without re-prompting for credentials.

A method as described by which an application executing in an application layer of a multi-layer communication protocol forming part of a general packet radio service (GPRS) session can signal for the setup and release of Temporary Block Flow (TBF) which will not be released during application execution in silent (inactive) periods. When applications such as voice, telnet or web browsing have specific traffic type data that have inactive periods between active periods are to be carried over GPRS, the session consists of multiple active periods. Current TBF release procedures lead to multiple TBF setups during such sessions. With the method described, a special type of TBF can be set up with special procedures for release of this TBF which greatly minimizes the need for multiple TBF setups during a session containing data transfers with inactive periods between active data transmissions.

A test manager software program includes an interactive test graphical-user-interface (GUI) for testing network devices using high-level networking commands. The test GUI allows the test engineer user to enter high-level commands such as Simple Networking Management Protocol (SNMP) commands that read values in a management information database in a network device under test. The high-level commands can be sent from the test manager using a command-line interface (CLI) in a telnet session opened to the network device during testing. The user specifies high-level test, analyze, and restore commands in test cases that are collected into test suites. Rules for logging on to the network device under test are stored that include expected prompts from the network device and user responses such as passwords. Addresses of the network device under test can be re-mapped for testing other devices so the test suites can be reused.

VPN tunnels may be established using an Internet browser and dynamically downloadable VPN client software that may be installed as part of a remote login process. By causing the VPN client software to be dynamically downloaded during the session, the remote user does not need to pre-load any software onto the computer that will be used as the remote computer. Thus, any computer with an Internet browser may be used to log into the enterprise network without first requiring the user of that computer to acquire rights to install a VPN client on the computer. By causing some or all of the dynamically downloaded software components to be deleted upon termination of the session, the components of the software may be made to be not available once the session has ended. Encrypted UDP may be used to transmit data on the VPN tunnel where exchange of an initial UDP packet indicates the availability of UDP connectivity.

The invention relates to the field of network topology discovery, in particular to a network physical topology discovering method and a network management server based on SNMP. The method comprises the following steps: obtaining IP addresses and corresponding MAC addresses of all devices in subnets in the network and gateway devices of the subnets; utilizing a telnet protocol to perform remote login to all the devices in the subnets, controlling each logged-in device to send an inquiry request message to all other devices in the subnet at which the device is located; utilizing the telnet protocol to read address forwarding tables which are established by logged-in exchangers based on the received inquiry response messages; and carrying out network physical topology discovery based on the address forwarding tables which are read from the exchangers in the subnets. The network management server utilizes the telnet protocol to complete the network physical topology discovery. The method and the network management server enable the exchangers in the network to establish relatively complete address forwarding tables, and compared with the results of a traditional network physical topology discovery, the results of the physical topology discovery have a great improvement.

The OPC client may include an event engine configured to process the XML-based events, and convert them to appropriate COM / DCOM API invocations. In some embodiments, the OPC client buffers collected data from the COM / DCOM API, and transmits the buffered data in an XML event to an application based on a subscription time schedule and / or value condition. The OPC client allows service oriented event-driven applications to interact with industry devices remotely via the open architecture provided by the OPC specification using a business level language syntax.

A remote control device is described. The remote control device uses a network chip directly mounted on a motherboard of a server computer to remote control the server computer without any additional network card requirement. The remote control device includes a basic input output system (BIOS), a COM port, a baseboard management controller (BMC), and a network chip. The BIOS redirects video data to the COM port and then the same to the BMC. The BMC transforms the video data into network packets according to a Q-Telnet protocol. The BMC recognizes the Q-Telnet protocol and a standard Telnet protocol effectively. Therefore, the network chip uses a UDP 623 port to control the BMC and a TCP 23 port to transmit data and commands using the standard Telnet protocol.

A network switch, configured for performing layer 2 and layer 3 switching in an Ethernet (IEEE 802.3) network without blocking of incoming data packets, includes a network switch port having a packet classifier module configured for evaluating an incoming data packet on an instantaneous basis. The packet classifier module performs simultaneous comparisons between the incoming data stream of the data packet and multiple templates configured for identifying respective data protocols. Each template is composed of a plurality of min terms, wherein each min term specifies a prescribed comparison operation within a selected data byte of the incoming data packet. Hence, the packet classifier module is able to monitor data flows between two network nodes interacting according to a prescribed network application. The packet classifier module determines the application state for a prescribed network application from a received layer 2 data packet, enabling switching logic within the network switch to utilize application-specific aging intervals for respective network applications such as HTTP, SNMP, ftp, Telnet, etc. in order to delete aged address entries from a network switch address table based on the supported network application. Determination of the application state from the received layer 2 data packet also enables the network switch to detect the end of a data flow for deletion of the corresponding address entry from the network switch address table.

A network managing apparatus detects a router capable of using Telnet from among nodes in a network and causes that router to send a broadcast ping to other nodes. Each node in the network returns a ping reply to the router. The ping and the ping reply pass through a switch before arriving at their destinations. When the ping and the ping reply pass thorough the switch, the switch extracts MAC addresses of sender nodes and store them in its MAC address table. Thus, accurate topology of the network can be obtained from the MAC address table of the switch.
