BSD socket interface
BSD socket is provided as the application interface. This makes it easy to reuse the network applications of POSIX software, including Linux. POSIX software engineer resources can also be used for application development.
Best-class performance in the industry
Optimized high-performance networking
Field-proven results in high-speed, multi-session video streaming products.
Checksum offloading support enables faster speeds at the hardware level.
Supports IP multicast function
Supports an IP multicast sending and receiving function, which enables the same data to be sent to multiple specified destinations at the same time. This is effective for distributing large-sized media data such as video or audio.
Adjustable memory size
TCP/IP Stack has a function selection switch for adjusting the overall code size. If the DHCP client, DNS client, IP multicast, or AutoIP function is not needed, this function selection switch can be used to specify the unused function during system configuration so that the function module is not embedded. The code is adjusted to the minimum required size to prevent wasteful memory consumption.
Supports various platforms
componentizes source code dependent on the target system, such as the operating
system, CPU, or NIC (Network Interface Card), as environment-dependent parts.
In addition, TCP/IP Stack is coded in C language. As a result, TCP/IP Stack has
excellent portability, making it easy to support various platforms. TCP/IP
Stack is configured to run on eT-Kernel and PrKERNELv4 as
standard. On eT-Kernel, it runs on various profiles such as eT-Kernel
Multi-Core Edition and eT-Kernel/POSIX.
When eT-Kernel is
used, TCP/IP Stack can be implemented either as a library or as a T-Kernel
subsystem. (Refer to T-Engine's
Software Architecture Configuration for more information about
subsystems.) Socket API is provided as the interface even when TCP/IP Stack is
implemented as a T-Kernel subsystem. When implemented as a T-Kernel subsystem,
TCP/IP Stack can also be used from a loadable system program or process
application. Loadable drivers can be added dynamically to TCP/IP Stack.
Various protocols provided as standard
TCP/IP Stack implements the following protocols as standard.
• DHCP client / DNS client / FTP client / FTP server / TELNET server
• IPv4/ARP/ICMP/IGMP/AutoIP, etc.
Many available optional protocols
The functions needed for use in the application can be selected. Dual stack for IPv4/IPv6 is also available.
|TCP/IP Stack Dual
||IPv4/IPv6 dual stack|
|TCP/IP Stack PPP
|TCP/IP Stack Mail
|TCP/IP Stack HTTPD
||HTTP server, HTTP server/SSL（https server）, HTML compiler|
|TCP/IP Stack SNTP
|TCP/IP Stack SNMP
|TCP/IP Stack SSL
|TCP/IP Stack other pptions||DNS server, DHCP server, IPSec, IKE library, RIPv1/v2, NAT, PPPoE etc|
* These optional protocols are released as required. The product configuration may be changed. Please contact us for details such as the release date.
Sample drivers and sample applications
A device driver that supports the network controller used in the system must be created for TCP/IP Stack. The following source code is included as standard as a sample for this device driver. In addition, sample source code for various applications are included as standard.
• Device driver for Ethernet
o RZ/A1 built-in Ethernet controller
o Zynq-7000 built-in Ethernet controller
o CycloneVSoC built-in Ethernet controller
o i.MX6 built-in Ethernet controller
•FTP sample application (server/client)
•TELNET sample application (server)
In addition to the samples included as standard, a wide range of controllers with a successful record of operation are available. Please feel free to contact us for details.
• Motorola 5282c3
• Intel 8255x
• SMSC LAN91C111
• SMSC LAN9118
• Marvell WLAN
• MPC8272/48, MPC8349 built-in Ethernet controller, etc.
Source code provided
TCP/IP Stack is provided as source code.
Maintenance service and customization service
The following maintenance service is provided. The maintenance service enables developers to use TCP/IP Stack with peace of mind.
• Response to email inquiries regarding the product
• Minor version upgrades
In addition, a customization service is available for supporting TCP/IP Stack in different environments, such as a custom real-time operating system or hardware.
