摘要： Apparatus, and accompanying methods for use therein, for an ISDN LAN modem (300) (and various aspects thereof) that is particularly, though not exclusively, suited for small user environments and which contains an internal ISDN router (305) having a self-contained network hub (340) for inter-connecting multiple network devices, such as workstations (10), to each other through a local area network (LAN) and for permitting each of those devices to each gain access through the router to any one of a number of different remote networks. Advantageously, to facilitate and simplify its configuration, the LAN modem automatically adapts itself to a current network environment of a workstation connected thereto, via the LAN, and then communicates with that workstation through a browser executing thereat to obtain configuration information from a user situated at the workstation. Additionally, the LAN modem, through use of a multi-tiered routing hierarchy including both destination- and source-based routing, accommodates several modalities of network communication not heretofore possible in a conventional router. Specifically, several different workstations can simultaneously communicate through the LAN modem with a common remote network (60) and share a single user account at a corresponding network service provider.

摘要： A multi-stage time division switch interconnects processors communicating over one or more channels on time division lines. One of the processors is designated as a common processor to provide the switching "mapping" information for the various stages of the switch sending the switching information to the memory and logic of each switched stage over dedicated channels which include channels on the time division line emanating from the common processor and time division channels which pass through several switches until the memory of the applicable switch is accessed.

摘要： Disclosed is a storage enclosure having a plurality of servers each having a storage controller. A second storage controller that is not part of any of the plurality of servers is embedded in the storage enclosure. The second storage controller is configured to process I/O commands directed to one of the server's storage controllers when a storage controller fails. In this manner, the storage controllers that are part of the servers may be fully utilized and still have a failover capability to the enclosure storage controller instead of another server storage controller that may also be fully utilized.

摘要： A system processes media, such as voice and video, in a scalable and secure manner. The system can process voice and video for a large quantity of users. For example, the system can enable large quantities of simultaneous phone conversations over an IP network. The IP network can carry voice, video, and other data concurrently. The system identifies which packets carry voice data, which packets carry video, and which packets carry other kinds of data. The system scales both with the quantity of users and in terms of network topology. Multiple digital signal processors (DSPs) can be controlled by and connected to a switching device via an Ethernet network. One or more DSPs connected to the switching device interact with the switching device as separate IP devices, in that each such DSP may have its own separate IP address to which IP packets may be addressed.

摘要： A LAN modem permits unambiguous routing for multiple workstations located on a LAN to each gain access through the LAN modem to any one of a number of different remote servers located on a number of different remote networks using a combination of public port number and public address of the workstation. There are instances where sessions are changed between the same workstation/server. This changing of sessions changes the public port numbers associated with each session, which destroys the above unambiguous routing, since the combination of a public destination IP address and a private destination port number is no longer the same unique value contained in an address translation table of the LAN modem. A four step hierarchical procedure is provided in which the LAN modem determines which workstation the packet is to be routed based upon value of fields stored in the network address translation (NAT) table or value of fields stored in a static table. The NAT table or static table entries are compared to the values of fields stored in the packet header.
摘要翻译： LAN调制解调器允许位于LAN上的多个工作站的明确路由，以便每个通过LAN调制解调器访问位于多个不同远程网络上的多个不同远程服务器中的任何一个，使用公共端口号和公共地址的组合工作站。存在在同一工作站/服务器之间进行会话更改的情况。由于公共目的地IP地址和专用目的地端口号的组合不再是包含在地址转换表中的唯一值，所以会话的这种改变改变了与每个会话相关联的公共端口号，这破坏了上述的明确路由 LAN调制解调器提供了四级分级过程，其中LAN调制解调器基于存储在网络地址转换（NAT）表中的字段的值或存储在静态表中的字段的值来确定要路由分组的哪个工作站。将NAT表或静态表项与存储在报文头中的字段的值进行比较。

To support auto-switching, the apparatus embeds, using call independent signaling, certain call-specific information, as non-standard data, within various conventional H.323 messages that transit between the paired gateways. Furthermore, for added local redundancy, this apparatus utilizes peered border elements within an H.323 administrative domain.

摘要： Apparatus, and accompanying methods for use therein, for an ISDN LAN modem that is suited for small user environments and which contains an internal ISDN router having a self-contained network hub for inter-connecting multiple network devices, such as workstations, to each other through a local area network and for permitting each of those devices to each gain access through the router to any one of a number of different remote networks. The LAN modem communicates network failure messages to a host workstation connected to the LAN by intercepting and responding to various DNS (domain name system) messages issued by that workstation and intended for a remote DNS server. Specifically, the LAN modem supplies its own network (IP) address in response to these messages, thus assuming a role of both a remote DNS server and a remote web server in order to implement a mechanism through which a fault-specific web page can be dynamically constructed and downloaded to the workstation for subsequent display, through a browser executing thereat. The page, once rendered, provides a specific message pertinent to the failure.
