KASAGO TCP/IP is a internet protocol stack designed and developed for embedded systems.
It features high performance, compactness, and reliability required for the development of high performance and advanced-capability digital equipment. It also achieves stronger security by providing original IPSec optimized for embedded systems.

KASAGO TCP/IP Base Development Kit includes ANSI C compliant source code of TCP/IP (IPv4) protocol stack, sample drivers, and users' manuals.

We also provide KASAGO IPv6 Base Development Kit for those cases that IPv6 connectivity is necessary.

High performance
	●	Efficient communication by optimized data forwarding routine and by supporting latest algorithm
	●	Increased processing speed by minimized internal data copy (Zero Copy TCP/IP)
Small Code size
	●	Less than 100KB minimum (including socket API)
	●	Customizable embedded program size
High portability
	●	MPU and OS interface descriptions contained in a header file and a c file. The c file is a container of system-dependent descriptions.
	●	CPU, OS, and compiler independent.
High reliability and quality
	●	Being provided with ANSI C source code
	●	Unified call names for variables, macros, and functions
	●	Enhanced source code comments
Variety of optional protocols;
	IPSec, Mobile IP, SIP, Web Server, Web Browser, NAT, FTP, TELNET, DHCP, IGMP, SNMP, POP3, SMTP, etc.

KASAGO TCP/IP Base Development includes;
	●	TCP, UDP, IP, ICMP, ARP, RIP Listener, BSD Socket I/F
	●	10 units of distribution license
	●	Users' manuals
	●	Sample Drivers (*Technical support does not cover any sample code.)
