PRESS RELEASE

Blunk Microsystems Releases TargetTCP 2002.0, High Performance TCP/IP Protocol Stack

San Jose, CA (June 11, 2002) Blunk Microsystems, a leading independent developer of turnkey software components for embedded devices, has completed release 2002.0 of TargetTCP. This release includes several enhancements and support for new protocols.

New Protocol Support:

  - Multicasting and IGMPv2 for low-overhead streaming audio and video.

  - SNMPv1 with integrated MIB-II agent for remote network monitoring.

  - AutoIP for automatic IP address assignment on local networks.

  - Wi-Fi (driver available separately) for mobile wireless access.

Enhancements:

  - Supports TCP out-of-band data and urgent data mark.

  - Telnet server integration with the TargetOS monitor, allowing full

    access to existing commands and easy extensibility.

  - TFTP client integration with the Standard C library, allowing remote

    files to be opened and read using the stdio file routines.

  - The TFTP loader now reads both ELF and S-record files. The loader's

    output can either be directed to memory for direct execution or to a

    buffer for use by the BSP flash programmer.

  - To provide more robust name to IP address resolution, the DNS client

    now accepts recursive referrals to other name servers.

  - For true 1-copy behavior with the Berkeley Sockets API, data copies

    occurring during fragmentation and defragmentation were eliminated.

  - New zero copy API for both TCP and UDP eliminates the data copy

    mandated by the Berkeley Sockets API.

  - For optimum performance, the Internet checksum routines have been

    re-implemented in assembly language.

TargetTCP 2002.0 supercedes Blunk’s prior TCP/IP protocol stack, TargetTCP, and contains all of its features, including: being a high performance RFC compliant TCP/IP protocol stack, providing the standard Berkeley Sockets API and supporting TCP, UDP, IP, ICMP, multicasting, IGMPv2, ARP, RARP, DHCP, SNMPv1/MIB-II, TFTP, FTP, Telnet, DNS, Ethernet, PPP (with CHAP, CHAT, and PAP), and Wi-Fi.
