摘要： A data communication network (DCN) having a plurality of network devices coupled to the DCN with at least one of the network devices having a “boot once” connectivity manager processor (CMP). The CMP receives its power over the DCN rather than from the power applied to the network devices. The CMP can execute special operating system code and maintain network connectivity even if the network device itself is powered off, is being booted or is otherwise non-functional. The CMP is also coupled to the network device's memory so that it may respond to out-of-band polling requests for device status information from network management tools. With CMP, network administrators can monitor the boot process of network devices, determine that a network device is non-functional due to power loss and can maintain an accurate inventory status of spare network devices that are stored un-powered in a spares closet.

摘要： In one embodiment, a source device (e.g., a VOIP phone) establishes a call connection with a remote device depending on which of multiple network paths provides an acceptable latency (e.g., a lower latency). For example, in response to receiving a request to establish a connection with a remote destination device over a network, the source device (e.g., a caller's phone) obtains multiple service code values. The source device encodes each of multiple data packets to include a unique service code value for transmission of the messages over different network topologies to a remote destination. Thus, when transmitted, each of the multiple messages follows a different logical network topology of a network as specified by a respective service code value. Based on feedback from a remote device that receives the multiple messages, the source learns a preferred logical network topology of the network for establishing the call connection.

摘要： The invention is directed to techniques for managing access to data available from a data access device using a network switching protocol to manage content requests from clients. A data communications device receives a request for content from a client. The data communications device, such as a network switch, exchanges signals using the network switching protocol with one or more data access devices, such as a web cache. The data communications device can then select one data access device to provide the requested content to the client based, for example, on load balancing considerations. The data communications device sends a data transfer approval signal to the selected data access device. The selected data access device establishes a connection with the client using information, such as the client's network address, provided by the signals. The selected data access device then bypasses the data communications device and sends the requested content to the client. Using the network switching protocol, the data communications device can manage multiple, pipelined requests from the same client, while approving responses to the client from different data access devices, such as web caches and/or servers.

摘要： A data communication device automatically configures its own communication ports based on attributes of a remote device with which it communicates. The process of configuring the communication ports includes monitoring a communications protocol associated with a remote device on a given communication port of the data communication device without participating in the communications protocol. The data communication device detects an attribute such as a network address associated with the remote device based on the monitored communications. In response to detecting the attribute of the remote device, the data communication device selects one of multiple configuration profiles depending on the detected attribute of the remote device to configure the given communication port.
