    Abstract: This invention concerns an autonomus media termination centric signaling architecture that takes advantage of both a peer-to-peer signaling protocol such as the SIP and Master/Slave protocols such as MGCP/Megaco/NCS. More specifically, the present invention describes an Internet telephony agent comprising a user agent call manager including a user agent stack for communication with a peer, a master stack, and a multi-protocol call manager for communication between the user agent stack and the master stack; and a media termination coupled to the user agent call manager including a hardware manager, and a slave stack for communication between the master stack and the hardware manager. The user call manager and the media termination of Internet telephony agent may be tightly coupled or loosely coupled, allowing the inter- operation of the Internet telephony agent with both SIP and MGCP/Megaco/NCS media terminations.

    Abstract: The Dynamic Host Control Protocol (DHCP) is a text-based protocol that functions over the Internet Protocol layer. The main use for this protocol i s to configure rebooting networking equipment. DHCP servers can assign dynamic IP addresses to DHCP clients from a pool of addresses, or can assign static addresses manually assigned by network administrators. Along with its assign ed IP address, a DHCP client is subject to receive a plethora of other useful configuration information. DHCP information, called options in DHCP lore, ar e typically registered with the IANA (Internet Assigned Numbers Authority), an d can have virtually any format for their data field. The present invention describes a generic way of adding new options of a DHCP client by specifying the data type for the option. This allows easy customization of DHCP clients . Typical examples of this optional information are the local subnet mask and the local router's IP address.

    Abstract: A system and a method allowing local network devices to be connected to a large network using only one IPv4 address, comprising a routing device havin g an interface to the large network and an interface to the local network. The method comprises providing a routing device hosting an application and havin g an interface to the large network and an interface to the local network, providing a local network device, connecting the local network device to the LAN interface of the routing device, whereby the routing device shares a public IP address between the application it is hosting and the local network devic e.
