1 BICC Key points: Basic concept of BICC. Protocol model of BICC. Signaling process of BICC 1.1 Overview 1.1.1 Background of BICC In the past few years‚ the demand for the integration of the data network and the voice network has become more obvious. The telecom network accesses the WWW through dialup. The IP network is also used to provide low-quality and low-cost voice services. The circuit contention results in the transferring of both voice stream and data stream over the ATM network

Internet and layered protocol architecture: Q1. (5 points) In the layered protocol architecture the transport layer functionality includes congestion control and error recovery (e.g.‚ retransmission). One suggested that this functionality should be done strictly at the end points (i.e.‚ at the hosts) without aid from the network. Do you

NAS typically makes Ethernet and TCP/IPconnections. | Identify and briefly describe each of TCP/IP’S five layer? The basic structure of communication networks is represented by the Transmission Control Protocol/Internet Protocol (TCP/IP) model. This model is structured in five layers. An end system‚ an intermediate network node‚ or each communicating user or program is equipped with devices to run all or some portions of these layers‚ depending on where the system operates. These five layers‚

Inside an SS7 network the nodes are referred to as signaling points. 5) (i) In a circuit switched network the set of switches are interconnected through a series

-- -- - The Evolution of XTP† Greg Chesson Silicon Graphics Computer Systems Mountain View‚ Ca 94039-7311 greg@sgi.com Abstract The design of XTP has been a 3 year process so far with roots traceable to work in the 1970’s and 80’s. There have been roughly ten distinct revisions of the protocol. Since Revision 3.4 in June 1989 there has been an effort to stabilize the design. This has been accomplished. The most recent versions - Revision 3.4 and 3.5 - were about 14 months apart whereas

one computer to another using layers? In a network of computers each computer connected must have a unique IP address. IP: 1.2.3.4 IP: 5.6.7.8 When a message is sent from one computer to another‚ it travels down the protocol layers of the model‚ and then up the layers of the stack on the other computer. The application layer is the application software used by the network user. The Transport Layer guarantees that the receiver gets the data exactly as it was sent. It is responsible for delivering
