'Now' I see you. That's fine: Video Phone Trial With Intel Corporation ----- Internet Cable Corp. Sees Growing Market In Video Phone Trial With Intel Corporation December 7, 1998 CHARLESTON, S.C., Dec. 4 /PRNewswire/ via NewsEdge Corporation -- Internet Cable Corporation's (OTC Bulletin Board: ICBL) high-speed duplex cable modem service in the Wild Dunes suburb of Charleston, South Carolina, will become a showcase for Intel Corp.'s (Nasdaq: INTC) Intel(R) Video Phone software designed specifically for cable modems and high-speed cable Internet connections. In addition, Intel will be working with several vendors in the CableNET '98 area at the Western Cable TV Show in Anaheim, CA to showcase the momentum of the International Telecommunication Union (ITU) H.323 communications specification, which ensures products from different vendors talk with one another. "Intel Video Phone technology is an ideal use of the high-speed cable connection in the home or small office," said Ali Sarabi, director of Broadband and IP Telephony Lab in the Intel Architecture Lab. "The increased bandwidth of the cable connection brings a new use to the PC: a world with richer communications, with full-motion, real-time video and audio to help keep consumers close to friends and family or business associates." Later this month, Intel plans to begin trials of its broadband enhanced PC-based Video Phone with Internet Cable Corporation over US Cable Coastal Properties' high-speed cable Internet connections in the Wild Dunes suburb of Charleston, S.C. Timothy Karnes, president of Internet Cable Corporation, commented, "These trials of an actual broadband product in a high-speed full duplex broadband system are truly a value-added service to our current and future customers. What better product could there be than one which allows local or long- distance communication with full, real-world sight and sound. We look forward to our larger cable modem competitors, such as @home Corporation (Nasdaq: ATHM) and the Time Warner, Inc. unit MediaOne Group, Inc. (NYSE: UMG) becoming fully bi-directional so their subscribers will be able to Video Phone our subscribers. ISPs (Internet Service Providers) such as EarthLink Network, Inc. (Nasdaq: ELNK), Mindspring Enterprises, Inc. (Nasdaq: MSPG) and America Online, Inc. (NYSE: AOL) simply do not have sufficient bandwidth over telephone lines for new broadband products. Our duplex system presents the proper and adequate environment for actual broadband technology and content to be correctly showcased." US Cable Coastal Properties is an affiliate of the privately held US Cable Group, of Montvale, NJ, which operates cable systems in South Carolina, Georgia, Florida, Texas and New Mexico. US Cable Group's telecommunications offerings include US Telecom, a telephone service provider that supplies convention centers, and USFI Network Services, Inc., a global provider of telecommunications services and networks to government markets. Internet Cable Corporation, headquartered in Charleston, South Carolina, is in the business of administering high-speed Internet access for cable TV companies on a revenue sharing basis. The use of cable modems for Internet access provides customers the ability to download and upload multi-media at speeds hundreds of times faster than those of typical telephone modems.

Latencies and security: In the case of PKCS (public key cryptosystem) the latencies are relatively high compared to say a (symmetric key) software DES implementation. For a 133 Pentium, software DES can decrypt roughly 600 kbytes per second whereas RSA would be in the sub-10kbyte/sec range (roughly 100:1 processing bandwidth difference). Of course, this depends on lots of things, like other system parameters and applications running. Also, RSA is generally used at initialization of the secure link, and a faster symmetric key algorithm is used for the bulk data transfer. Since (single)DES is now considered compromised, it's only used in cases where the key lifetime is very short (a phone conversation might qualify for this). Triple-DES would significantly increase the latency because of the increased processing load, but I have no numbers for that. As you mentioned, the need to go to another server for certificates or whatever could without a doubt cause a latency that would preclude real-time anything. Fortunately, this should only be a start-up problem for the call initialization (unless I misunderstood your comment). There's also the question of the degree of security needed for telephony. Is IP telephony billed as a secure communications link, or just semi-safe? Lots of liability issues involved in making generic security claims; most providers are unwilling to assume that liability, and probably won't until they are forced to by competition (can't blame ‘em). Still, the underlying internet doesn't guarantee bit rates, even if the system processing bandwidth isn't being taxed . IEEE802.14 addressed QoS by adopting the ITU-defined service categories of: constant bit rate, non-real-time variable bit rate, unspecified bit rate, and available bit rate. There was also a real-time variable bit rate category. Haven't really been following 802.14 recently, but I believe the DAVIC spec and 802.14 were closely aligned. But, this would only apply to the private portion of the network anyway. You know, come to think of it, not one of the latency calculations I've seen(or "latency schedules") took delays in the security processing into consideration. I'm sure that's partly because security has taken a back seat (locked in the trunk might be a better phrase) in the spec-generating process, and partly because it is dependent on the user's system capabilities, and.... Also, what ever happened with Ipv6? DHCP would go away, and a host of other improvements related to security and quality of service. There was even a plan for a seamless transfer from Ipv4 where the 2 could coexist until the transition was complete. Last I remember (about a year ago), only the router protocols and some key management issues (i.e. management of security keying information--not "important managerial" issues) remained as unsolved (or unagreed upon). Anyone know the status? (Frank: not sure if this addressed your question. If not, please re-phrase) dh Prediction: Future systems (3-5 years out) will have a dedicated "communications processor" which handles the broadband (soft cable modem--demod and FEC (may sound crazy today)) and handles the security, in order to offload the main system processor. May even handle the A/V decode. Fixed/hard solutions won't cut it--too inflexible. This will be on the "always awake" part of the motherboard. Why? Computational needs (or potential computational needs) are growing at a much greater rate than computational power or process shrinks. There's also a fairly clean demarcation of the sections that must be "always awake."
