BlueBoC application areas
advent Bluetooth (Personal Area Networking) protocol profile signals coming generation datacom products based Bluetooth. essentially based BNEP (Bluetooth Network Encapsulation Protocol) which emulates Ethernet over Bluetooth. BNEP's overhead Ethernet's plug-and-play features match perfectly characteristics Bluetooth protocols such baseband, link management, service discovery. This presents radical change from previous solutions which Bluetooth indeed treated "cable replacement" technology, leading continued heavy serial line emulation protocols this type "cable". With technology moves from mere physical cable replacement both physical operational cable replacement.This essential ad-hoc group networking. will greatly improve Bluetooth's usefulness appeal day-to-day wide range products, illustrated below.

Ethernet bridging using BlueBoC
access point based BlueBoC will typically operate bridging device forwarding Ethernet frames between users connected over Bluetooth. Such users PANenabled portables cellular phones. BlueBoC based access points will also provide data forwarding between users external units over Ethernet interface. Access control enforced through authentication using Radius servers accessible over fixed Ethernet interface. embedded TCP/IP BlueBoC used both manage access point/hub well support embedded applications, e.g. locally resident WAP/Web server. Ethernet back-end also employed remotely manage access point perform content management embedded applications.

Software architecture
BlueBoC implements Generic Access Profile (GAP) profiles, Network Access Point Group Network.These profiles provide Ethernet bridging services. BlueBoC applications built high-quality, scalable RTOS which offers full functionality concurrent operation, reconfiguration, multiprocessing. TCP/IP stack provides UNIX compatible socket library embedded BlueBoC applications communicate with TCP/IP peers across network.The stack includes support TCP, UDP, HTTP, SNMP Telnet. Bluetooth protocol stack consists Bluetooth upper protocols, integrated (embedded) layer, Bluetooth lower layer protocols, baseband device driver infrastructure holding place providing software services protocols. Network Access Point (NAP) bridging entity provides relay services between device connected Bluetooth service Ethernet interface (IEEE 802.3 physical port). implements parts IEEE 802.1D (bridging) applicable Bluetooth Personal Area Networks specified Bluetooth Profile.This includes learning, forwarding basic filtering. entity further provides access SNMP/HTTP based network management entity BlueBoC. Group Network (GN) entity similar with difference that only bridges between devices connected Bluetooth. Hence, does forward traffic physical Ethernet interface.This employed confine Bluetooth Ethernet packets local piconet. SPICE Spirea Control Entity. implements element management control functions BlueBoC. distributes events applications configures underlying Bluetooth resources accommodate actual needs, e.g. discoverability connectability. SPICE employs configure radio link controller resources.
