The document discusses VoIP (Voice over Internet Protocol), benefits and challenges of VoIP including quality of voice and codecs, protocols used like SIP and RTP, and provides an example of Asterisk call logic and demonstration. It explains that VoIP uses internet packet switching instead of traditional circuit switching, has benefits like cost savings and integration of data and voice. However, quality of voice depends on factors like codec used, delay, jitter. Protocols like SIP are used for call setup and RTP for media transmission. The document concludes with a demo of an Asterisk PBX with SIP clients, local phones and an IAX2 trunk between servers, showing least cost routing using ENUM.
The document discusses tuning NFS for Oracle databases. It covers network topology issues like routers and switches that can increase latency. NFS configuration is also important, specifically MTU size for jumbo frames, TCP window size, and congestion window settings. Properly configuring these NFS and network settings is necessary to achieve best performance and avoid dropped packets or out of order delivery.
Overview of VoIP (Voice over IP) and FoIP (Fax over IP) technologies like Session Initiation Protocol and H.323.
Even though voice over IP (VoIP) was hailed as a technological innovation, the idea to transport real-time traffic over TCP/IP networks was not new back in the 1990s when VoIP started being deployed in networks. Chapter 2.5 of the venerable RFC793 (TCP) shows both data oriented application traffic as well as voice being transported over IP based networks.
Nevertheless, VoIP puts high demands on signal and protocol processing capabilities so it became possible at reasonable costs only in the 1990s.
VoIP can be roughly split into two main functions. Signaling protocols like SIP (Session Initiation Protocol), H.323 and MGCP/H.248 are used to establish a conference session and the data path for transporting real-time voice data packets. SIP has largely supplanted H.323 in recent years to its simpler structure and packet sequences. MGCP and H.248 are mostly used in carrier backbone networks.
Protocols like RTP (Real Time Protocol) transport voice packets and provide the necessary information for receivers to equalize packet flow variations to provide a smooth playback of the original voice signal.
Voice codecs are one of the core functions of the data path. Voice compression reduces the bandwidth required to transport voice over an IP based network. Compression may be less of a concern in local area networks with gigabit speeds, on slower links like 3G (UMTS, LTE) it still makes a lot of sense.
The algorithms used in different codecs make use of various characteristics of the characteristics of human speech recognition. Redundant information is removed from the signals thus slightly reducing the quality, but greatly reducing the required bandwidth.
In VoIP networks, the echo problem is typically compounded by the increased delay incurred by packetization of voice signals. To counteract the echo problem, VoIP gear (hard phones, soft phones, gateways) include echo cancelers to remove echo signals from the transmit signal.
To transport facsimile over an IP based network, even more technology is needed. Facsimile protocols are very susceptible to delay and delay variation and thus need more compensation algorithms. Protocols like T.38 terminate facsimile protocols like T.30 (analog facsimile) and transport the fax images as digitized pictures over IP based networks.
