Abstract: A telephony system (10) for communication over a network includes a kernel space (110), a media express processor operating environment (120) for providing a set of software facilities for task synchronization, and a user space (130). The kernel space includes a board support package (111), a ucLinux module (112), a digital signal processor interface module (113), a transfer control protocol/Internet protocol (TCP/IP) stack (114) for performing TCP/IP, and a real-time transport protocol/real-time transport control protocol module (115). The user space includes a digital signal processor manager (132), an H.323/session initiation protocol (H.323/SIP) stack (133) for performing H.323 protocol or SIP, a system managing module (134), an event dispatcher (135), a line state machine (136), a call manager (137), a call logging module (138), and a directory module (139) for storing, editing, searching and removing contact information of users.

Abstract: A dynamical host allocation method employed in a dynamical host allocation system (100) is disclosed. The employed dynamical host allocation system includes a plurality of DHCP servers (110), a DHCP relay (120), a plurality of DHCP clients (130) and a network (140) interconnecting all these apparatuses. When allocating IP addresses to the plurality of DHCP clients, the plurality of DHCP servers determine whether the IP addresses are free by way of successive logic checks. Therefore, the problem of allocating an IP address to more than one DHCP clients is resolved.

Abstract: An event logging system (5) includes one or more message sources for generating messages, an event logging library (54) for formatting the messages, a local event logging daemon (57) for distributing the messages, and one or more message destinations for receiving the messages. The local event logging daemon distributes the messages from said message sources to said message destinations. The message sources include one or more of an application (50), a hook (51), a kernel module (56), an internal buffer (59) and a remote event logging daemon (58). The message destinations include one or more of said hook, said internal buffer, said remote event logging daemon, a file system (52) and a mail system (53). The event logging system further includes a kernel logging daemon (55) for transmitting the messages from said kernel module to the event logging library. A related method for logging the messages is also provided.
