This document discusses VoIP (Voice over Internet Protocol) technology. It begins with an introduction to VoIP, explaining that it encapsulates voice data into internet protocol (IP) packets and transmits them over the internet rather than the public switched telephone network (PSTN). It then covers the components of VoIP including user agents (softphones, IP phones), proxies (softswitches), protocols (SIP, H.323, IAX), and codecs (formats for encoding voice data). The document also discusses quality of service, legal issues, and considerations for implementing VoIP.
The document discusses Voice over IP (VoIP) and IP telephony. It explains that VoIP allows phone calls to be made over an IP network like the internet instead of the traditional public switched telephone network (PSTN). VoIP offers cost savings compared to PSTN and enables additional features like video calls and mobility. The document also discusses when companies should consider replacing their private branch exchange (PBX) phone system with an IP telephony system using VoIP.
VoIP allows users to make phone calls using an Internet connection instead of a traditional phone line. It works by converting voice signals to digital data that is transmitted in packets over the Internet. A VoIP network uses protocols like SIP and RTP to setup calls and transmit voice data. Components include VoIP protocols, gateways to interface with the PSTN, and codecs to compress voice signals. Businesses are attracted to VoIP as it can help reduce costs while improving utilization of bandwidth and network management. However, security risks like hacking and eavesdropping exist since VoIP uses the public Internet.
This section provides background on VoIP applications and their components. It discusses how VoIP works by transmitting voice packets over IP networks, unlike traditional PSTN which uses circuit switching. The two main VoIP protocols are H.323 and SIP, which provide call control and setup. UDP is typically used instead of TCP for transmitting VoIP due to its lower overhead and lack of error checking, which is tolerable for voice transmission. IPv4 and IPv6 can both be used to transmit VoIP, with IPv6 having a larger header size.
1. IPTV delivers television content over the internet rather than through traditional cable or broadcast means. It allows viewing on computers, televisions through set-top boxes, and mobile devices.
2. Key advantages of IPTV include interactive programming, content on-demand, multi-screen viewing, and potentially lower costs compared to cable.
3. IPTV uses internet protocols to compress and deliver video and audio content. Live television uses multicast transmission while video on-demand uses unicast.
The document discusses various networking protocols and standards related to professional media over IP, including:
- SMPTE ST 2110 standards that define carriage of uncompressed video, audio, and data over IP networks as separate elementary streams.
- AES67, which enables high-performance audio-over-IP streaming interoperability between different IP audio networking products.
- Other relevant standards and protocols like SMPTE ST 2022, AIMS recommendations, Video Services Forum TR-03/04, RTP, SDP, PTP, and IGMP.
- Considerations for designing IP infrastructures for media networks, including capacity, connectivity, timing, control, and redundancy.
Ultra high definition TV over IP networksThomas Kernen
This document summarizes a demonstration of transporting Ultra High Definition TV (UHDTV) over an IP network. The demonstration showed that UHDTV video streams can be carried over existing IP infrastructure by using Quality of Service protocols to prioritize the video traffic. However, proper network management is required to ensure video quality is not degraded by other network traffic. The demonstration used commercial equipment to encapsulate UHDTV signals from a playout server into IP, transmit them over an IP network, then decode and display the signals with no visible quality loss or latency issues.
This document summarizes video services including H.323 video conferencing, MPEG2 broadcast quality applications, gateways, MCUs, streaming servers, satellite and microwave gateways for broadcast applications, and codec and bandwidth requirements.

Webinar Recording: https://www.panagenda.com/webinars/hcl-notes-and-domino-license-cost-reduction-in-the-world-of-dlau/
The introduction of DLAU and the CCB & CCX licensing model caused quite a stir in the HCL community. As a Notes and Domino customer, you may have faced challenges with unexpected user counts and license costs. You probably have questions on how this new licensing approach works and how to benefit from it. Most importantly, you likely have budget constraints and want to save money where possible. Don’t worry, we can help with all of this!
We’ll show you how to fix common misconfigurations that cause higher-than-expected user counts, and how to identify accounts which you can deactivate to save money. There are also frequent patterns that can cause unnecessary cost, like using a person document instead of a mail-in for shared mailboxes. We’ll provide examples and solutions for those as well. And naturally we’ll explain the new licensing model.
Join HCL Ambassador Marc Thomas in this webinar with a special guest appearance from Franz Walder. It will give you the tools and know-how to stay on top of what is going on with Domino licensing. You will be able lower your cost through an optimized configuration and keep it low going forward.
These topics will be covered
- Reducing license cost by finding and fixing misconfigurations and superfluous accounts

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...Alex Pruden
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).
