Compact, efficient and high-speed

• The small program size allows operating even if the capacity of both ROMs and RAMs are small.
• Ubiquitous Network Framework can be made more compact by limiting its functionalities.
• Ubiquitous Network Framework is designed and optimized for efficient operation. This means it achieves very low CPU occupancy.

Supported Protocols

• ・Network layer: IP, ICMP, ARP, IGMP/MLD
• ・Transport layer: TCP, UDP
• ・Application layer: DHCPc, DNSc, NTPc, POPc, SMTPc, HTTPd, FTPd, TELNETd
• ・Others: UPnP Device Architecture v 1.0, UPnP Control Point, Bonjour

Support for a dual stack is provided.

• ・IPv4 Edition
• ・IPv6 Edition: Provides support for a dual stack, which allows IPv4 and IPv6 to coexist

Code size

Examples (in the case of an ARM CPU core)

Component	Thumb instruction set	ARM instruction set
Kernel core	1.9K Byte	2.7K Byte
TCP/IP (v4)	9.4K Byte	14.3K Byte
UPnP	9.9K Byte	13.0K Byte

The above figures represent the sum of ROM size and fixed RAM size. Footprint values vary depending on CPUs, compilers, compile options, modules, etc. being used.

Speed Benchmark

Component Options are provided as components that are assumed to be needed for final products, and can be used for secure communication, which is done by the addition of the Security Option consisting of encryption libraries such as SSL, and making it possible to develop products conforming to the DLNA (Digital Living Network Alliance) standards for multimedia home networks, which is done by the use of the Home Network Option.
Each component is designed to operate very compactly and efficiently, as is the case with other products. The addition of a component results in an increase in the program size and the minimum required frequency of the CPU. However, the addition of functionalities at low cost is achieved by the minimization of such increases.

Security Option

• ・Security Option is a component for encrypted communication that is necessary for transmitting and receiving encrypted information in TCP/IP communication.
• ・This component provides functionalities for SSL and TLS, both of which are protocols typically used to transmit and receive confidential information via the Internet.

Home Network Option

• ・Home Network Option is a component that is necessary for developing appliances supporting home networking.
• ・Home Network Option provides components that are necessary for implementing functionalities conforming to standards for interconnection among devices in a home network, such as UPnP AV (Universal Plug & Play) and DLNA (Digital Living Network Alliance).

Link Protection Option

• ・Link Protection Option is a component for encrypted communication that is necessary for sharing copyrighted digital contents in a home network.
• ・This component provides DTCP-IP (Digital Transmission Contents Protection), which is necessary for retransmitting digital terrestrial broadcast programs recorded with a DLNA-compliant video recorder, and Windows Media DRM-ND, which is necessary for retransmitting copyrighted contents distributed from a Windows PC, such as Windows Media Center.

Wireless Option

• ・Wireless Option is a component that is necessary for developing devices supporting wireless LANs.
• ・This component provides the Supplicant functionality of WPA (Wi-Fi Protected Access), which is a protocol for encrypted communication that was standardized by the Wi-Fi Alliance and is necessary for wireless LAN communication. It also provides the WPS (Wi-Fi Protected Setup) Enrollee functionality, which is a functionality to easily set up connections and security settings for wireless LAN devices.

“Network Offload Engine” (a solution package)

Network Offload Engine is a solution package integrated into the hardware that is intended to offload network processing from a host system and place the processing on a subsystem, and thereby resolve various problems that occur during the implementation of a network functionality. For more information, please refer to the Network Offload Engine Web page.
