Today we released version 1.6.3 of Streamline, a stream-based network subsystem for Linux.   This first release in over a half year has been thorougly stress-tested, so it should be more stable. New features include support for named and unnamed pipes, the full POSIX file IO interface, a write-after-read optimization similar to splicing, a method for catching HTTP GET requests and self-resizing (based on load) ringbuffer designs. Please read the changelog for more details.

(InfoWorld) - Cisco launched this week the smallest version yet of its biggest router -- a four-slot Carrier Routing System-1, intended to extend 40Gbps from a core network to regional carrier POPs, Cisco says. The four-slot CRS-1 joins its eight and sixteen slot brethren and offers carriers another tool for expanding 40Gbps, or OC-768 connectivity throughout a network. The device includes four slots which can support four-port OC-192 (10Gbps) line cards, or single-port 40Gbps blades. The box also includes several traffic shaping and network virtualization features aimed at serving business and consumer network customers, Cisco says. The four-slot CRS-1 supports up to 320Gbps of total routing capacity, Cisco says. Traffic management features in the router also allow users to carve up bandwidth or network services for various customers, with Secure Domain Routers. This feature allows users to create a virtual router for each line card in a CRS-1 system. The traffic on virtual Secure Domain Routers is segregated from other network segments, keeping various customer's data from mixing, and allowing carriers to apply different rules to traffic, and use different protocols and technologies for customer networks. (For instance, a CRS-1 serving both a consumer video on demand -- VOD -- network and a business services network could activate multicast on a VOD Secure domain router, and MPLS and IP VPN services on the business network virtual router, Cisco says). The four-slot CRS-1 was an important piece in the puzzle for Sprint's nationwide network upgrade, which will begin this quarter using CRS-1s across all levels of the network. The smaller size of the four-slot CRS-1 will allow Sprint to expand the reach of its 40Gbps network to smaller locations, which may have only had 10Gbps connectivity in the past, according to Iyad Tarazi, vice president of network development at Sprint. The smaller-size CRS-1 can also operate with multiple CRS-1 chassis in Cisco's multi-chassis routing configuration, which allows multiple CRS-1 boxes to be lashed together for greater failover and distributed router processing capabilities, Cisco says. The four-slot CRS-1 will be available in November starting at $160,000.

It seems  PubSub.com is offering a bounty  on an HTTP Delta implementation of RFC 3229.  This seems in response to the current meme  of RSS and Atom syndication bloat.   First off this is certainly *very* generous of them.  I'd like to see this happen more.  Good for you guys!  I myself  have thought that HTTP Deltas were a viable solution but I was wrong.  Of course most people aren't familiar with HTTP deltas.  Eseentially what an HTTP delta enables is a client/server differential protocol that can exchange a patch from the server to the client.  The client is then patched and it will then have the updated version without having to transfer the *entire* document again.  For example say you ...

Mike Wallner has announced the release of the first beta of the pecl_http PECL package, an extension that "aims to provide a convenient and powerful set of functionality for one of PHPs major applications."   So, finally a first beta of pecl_http 1.6 has been released. This is the first version which supports libcurls multi socket API introduced in 7.16 through libevent.   The rest of the post shows stats comparing the timing on a normal connection versus using the multi-socket API (on both an empty file and a 100k file).

(InfoWorld) - Caspian Networks, a one-time core router startup that today makes devices to improve network performance, is on the block. The San Jose, California, company is considering a possible acquisition deal, said Tom Gibson, a spokesman for Morgenthaler Ventures, an investor in Caspian. He declined to give more details and Caspian President and Chief Executive Officer Brad Wurtz could not be reached for comment. Early in this decade, Caspian said it was building a massive IP (Internet Protocol) routing switch that could be expanded through using multiple linked hardware platforms with distributed software. It would segment traffic into separate "flows" that would receive different treatment, allowing for guaranteed quality of service. But the platform didn't gain much traction with carriers, and like other big carrier-gear vendors, Caspian hit hard times when the telecommunications bubble burst. A news report Thursday said the company had shut down. Caspian was richly funded by venture investors and pulled in $55 million in a funding round as recently as last year. Among the founders of Caspian was Internet pioneer Lawrence Roberts, who made dire predictions while at the helm of the company about Internet traffic growing far faster than the capacity of core routers, which are computers that transfer extremely large volumes of traffic on the Internet. Roberts has since left the company. Today, Caspian sells two Media Controller devices designed to let enterprises and service providers enforce quality of service policies. They also let carriers allocate bandwidth to users based on how much they pay, according to the company's Web site. Earlier this year it announced customer deals with Chunghwa Telecom Co. of Taiwan and China United Telecommunications.ADVERTISEMENTMAKE SOA REAL WITH IBM WEBSPHERE PODCASTStreamline processes and maximize efficiency within a proven service oriented architecture.
