  • General Packet Radio Service (GPRS) Packet data transmission has already been standardized in GSM phase 2, offering access to the Packet Switched Public Data Network (PSPDN); see Sections 9.5.3 and 9.6.2. However, on the air interface such access occupies a complete circuit switched traf®c channel for the entire call period. In case of bursty traf®c (e.g. Internet traf®c), such access leads to a highly inef®cient resource utilization. It is obvious that in this case, packet switched bearer services result in a much better utilization of the traf®c channels.

  • This brief guide aims at explaining the basic steps for getting started with GPRS. It supposes you are a bit familiar with GPRS concepts, like network attachment, session or PDP context. This guide is not intended to give full details about how GPRS works, all GPRS-specific AT commands (check out the GPRS AT command manual). By default depending on the firmware version, the MS starts up either in class CG (i.e. in GPRS mode and not in GSM mode) or in class B.

  • RIP version 2 is not a new protocol—it is RIP Version 1 with some additional fields in the route update packet, key among them being subnet mask information in each route entry. The underlying DV algorithms in RIP-2 are identical to those in RIP-1, implying that RIP-2 still suffers from convergence problems and the maximum hop- count limit of 16 hops.

  • The paper aims in providing a securely communicating of data between the devices which are nothing but appliance of Home Area Network (HAN) by a set of controller outside the HAN. The packets generated by the controller should be delivered fast without any interruption. The role of an HAN controller is like a gateway, whose role is to filter the incoming packet. Due to this HAN controller, the data in the packets should not be modified & it should not cause any delay in encryption & decryption of the packets.

  • The H.323 standard is a cornerstone technology for the transmission of real-time audio, video, and data communications over packet-based networks. It specifies the components, protocols, and procedures providing multimedia communication over packet-based networks (see Figure 1). Packet-based networks include IP–based (including the Internet) or Internet packet exchange (IPX)–based local-area networks (LANs), enterprise networks (ENs), metropolitan-area networks (MANs), and wide-area networks (WANs).

  • Multicast is UDP Based!!! Best Effort Delivery: Drops are to be expected. Multicast applications should not expect reliable delivery of data and should be designed accordingly. Reliable Multicast is still an area for much research. Expect to see more developments in this area. No Congestion Avoidance: Lack of TCP windowing and “flow-control” mechanisms can result in network congestion. If possible, Multicast applications should attempt to detect and avoid congestion conditions. Duplicates: Some multicast protocol mechanisms (e.g.
