Accelerated Technology Announces Upgrade for Networking Software, Nucleus NET 5.2.MOBILE, Ala. -- Accelerated Technology(R), the Embedded Systems Division of Mentor Graphics Corporation (Nasdaq:MENT), today announced the Nucleus(R) NET 5.2 software, a major upgrade of the Nucleus networking protocol stack. This release of the Nucleus NET software will give developers a networking stack with advanced features including hardware checksum A value used to ensure data are stored or transmitted without error. It is created by calculating the binary values in a block of data using some algorithm and storing the results with the data. offloading, support for Internet Group Multicast Protocol version 3 (IGMP (Internet Group Multicast Protocol) The protocol that governs the management of multicast groups in a TCP/IP network. To sign up for a multicast group, a Host Membership Report is sent by a user's machine to its nearest routers, which forward that data to ), dynamic removal of network interfaces and virtual Local Area Network (VLAN See virtual LAN. VLAN - Virtual Local Area Network ) support. The new features are in addition to those protocols already supported by the Nucleus NET software including TCP, UDP UDP (uridine diphosphate): see uracil. (User Datagram Protocol) A protocol within the TCP/IP protocol suite that is used in place of TCP when a reliable delivery is not required. , IP, ICMP (Internet Control Message Protocol) A TCP/IP protocol used to send error and control messages. For example, a router uses ICMP to notify the sender that its destination node is not available. , IGMP, ARP, RARP (Reverse ARP) A TCP/IP protocol used by a diskless workstation to obtain its IP address. Upon startup, the client station sends out a RARP request in an Ethernet frame to the RARP server, which returns the layer 3 address for a layer 2 address (performing the opposite , DNS (Domain Name System) A system for converting host names and domain names into IP addresses on the Internet or on local networks that use the TCP/IP protocol. For example, when a Web site address is given to the DNS either by typing a URL in a browser or behind the resolver, DHCP client, BOOTP (BOOTstrap Protocol) A TCP/IP protocol used by a diskless workstation or network computer (NC) to obtain its IP address and other network information such as server address and default gateway. client, RIP/RIP II and TFTP client. Hardware checksum offloading has been provided for the Nucleus NET 5.2 software in order to increase the speed and performance of networked applications. In addition, the Nucleus NET 5.2 software now adheres to IGMPv3 support, the protocol governing the management of multicast groups in a TCP/IP TCP/IP in full Transmission Control Protocol/Internet Protocol Standard Internet communications protocols that allow digital computers to communicate over long distances. network. This new protocol increases the Nucleus NET stack's interoperability with the latest network equipment on the market. Other changes made to the Nucleus NET 5.2 software include the dynamic removal of network interfaces. This feature paves the way for networking developers to use hot-swappable network devices with the Nucleus NET protocol stack such as 802.11 (or Ethernet), PCMCIA card or CompactFlash cards and 802.11 (or Ethernet) over Universal Serial Bus See USB. (hardware, standard) Universal Serial Bus - (USB) An external peripheral interface standard for communication between a computer and external peripherals over an inexpensive cable using biserial transmission. (USB USB in full Universal Serial Bus Type of serial bus that allows peripheral devices (disks, modems, printers, digitizers, data gloves, etc.) to be easily connected to a computer. ). Many new products are adding support for this type of removable media and the Nucleus NET 5.2 software opens the door for the Nucleus developers to enhance their products with these emerging technologies. The Nucleus NET stack upgrade also offers VLAN support. Applications such as Voice over Internet Protocol (VoIP) that require quality of service (QoS) support from the network often need VLAN support with priority tagging. In the office setting, large corporations use VLAN for their local network to improve overall network performance. Additionally, customers that create network-enabled devices, e.g. a printer, to be used in this type of environment will need VLAN support in order for their device to function on the local network. "The networking world is constantly changing to keep up with new technology and to meet market demands. Because of this, the Nucleus NET software has also evolved to meet this challenge. The Nucleus NET 5.2 software is the latest installment of our core networking support, adding new features that meet the demands of today's applications," said Robert Day, director of marketing, Embedded Systems Division, Mentor Graphics. Pricing and Availability The Nucleus embedded software is sold in source code format and without royalty fees. Licenses for the Nucleus NET begin at $14,495.
