Newsletter “Under The Hood” Spring 2012

The gearbit newsletter “Under The Hood” Spring 2012

Here’s the article that Google wrote around performance. At Gearbit, we’ve been seeing performance improvements turning off “Slow Start”  and “Nagles’s algorithm” in the TCP stack in the servers. We also have been concerned about “buffer bloat” That is mentioned, but they have achieved a whopping 64% reduction with “page load time” by a newly developed protocol that they call “SPDY”. It adds a session layer atop of SSL for muliple concurrent interleaved streams, that can be invoked from client or server. SPDY improves HTTP increasing the number of streams, so that data can be more effectively set. Traffic is still managed by TCP with algorithms that monitor the ACK times, providing a congestion control, so that the network links don’t get congested. This will save server, firewall and load balances resources. Just think, we might get others to quit blaming the network!

Google works on Internet standards with TCP proposals, SPDY standardization

SPDY adds a session layer atop of SSL that allows for multiple concurrent, interleaved streams over a single TCP connection.

 

The usual HTTP GET and POST message formats remain the same; however, SPDY specifies a new framing format for encoding and transmitting the data over the wire.

 

Streams are bi-directional, i.e. can be initiated by the client and server.

 

SPDY aims to achieve lower latency through basic (always enabled) and advanced (optionally enabled) features.

Issues
Ethernet Advantages: As the most common LAN technology, Ethernet is widely used and understood. Standards are managed through IEEE (IEEE 802), and work on new standards proceeds continously. Chips, parts, boards (particularly network interface cards or NICs), and expertise are all widely available. The Ethernet ecosystem is large and has many significant players, such as Cisco Systems, Intel, Broadcom, Marvell, Alcatel-Lucent, Hewlett-Packard, and Ericsson. Trade groups such as the Ethernet Alliance and MEF are very active and promote education, testing, and certification.

Challenges Facing Ethernet: Need for higher speed with 100-Gigabit Ethernet on the horizon, need for management, quality assurance, and security tools as Ethernet moves into service provider networks, reducing power usage, increasing bandwidth, and the need for software to handle storage-over-Ethernet and new approaches such as convergence and Fibre Channel over Ethernet.

Major Issues: Higher speed, higher effective bandwidth, lower power consumption, quality-of-service, security, management tools, test equipment, certification, convergence

What the experts are saying about Ethernet Technology

“FCoE, which combines the best of both worlds of Fibre Channel’s SAN predominance and Ethernet’s LAN predominance, is once again the newest addition to the long history of network technologies due to Ethernet’s powerful installed base as a physical network medium. Ethernet continues to preserve network infrastructure investments by virtue of continuous innovation while staying true to its massive client base.”

Conference Information

Server Design Summit is the only event focused entirely on the $40 billion server market. And it is the first event to deal with “Bringing Servers into the Cloud Computing Era”.

It will cover such key emerging topics as virtualization and consolidation, cloud computing, green design and energy saving methods, solid state drives, open specifications and standards, blade and appliance servers, high-performance servers, power and cooling, and low-latency and high-availability applications.

The Server Design Summit focuses on the design of next-generation servers ranging from simple blades to powerful high-end systems. Servers have the primary function of managing data transfers rather than actual computing. They generally operate in large racks in data centers. Problems include load balancing, power dissipation, consolidation, and expansion. Current issues include designing for virtualization and cloud computing, reducing power consumption, managing large numbers of servers (server farms), increasing throughput and performance, and bundling of servers, interfaces, and software into unified architectures. Other issues include the use of advanced interfaces and storage devices such as 10/40/100GbE, InfiniBand, NAS, SAN, and solid state drives.

Newsletter “Under The Hood” Winter 2012

The Gearbit newsletter “Under The Hood”

When examining the ongoing health of your network, it’s
important to have those important statistics. Most of us
use systems that show the up-down status, tell us the
utilization of various segments and ports of the network.
Even have some ability to measure response time. Not
to mention server performance, some status of DNS and
the firewall. But is that enough? When faced with an
application response time is slow, or VoIP quality is poor
will the statistics give you the answer?
Recalling a response time problem at a finical institution, a few techs gathered together in the bosses office to device a
game plan. As the information unrolled, with each person giving their thoughts on the matter, the list of things to check
began to grow. One tech insisted that the wiring needed to be redone at this location. He was convinced it had to be the
problem. Well, that was his area of expertise and he had just completed a site tour of this location. It was a mess. But was
that the problem? How do you know? I’ve found locations where this is the problem.
I find going back to the basics is needed from time to time. Ask yourself how did the information get from client to server
and back again? Starting at the Client PC leaving the operating systems, through the network interface, on the wire
through the switches, routers, firewalls, WAN compression, and oh yea then the cloud.
Getting to this information can sometime only be compiled with a protocol analyzer, viewing the packets and
understanding the traffic flow. Even today’s tools, such as Wireshark, will present this information to you in charts, graphs,
but it’s important to view the packet flow, down to the transaction to see if all is well.
Better analysis delivering and building more credibility diagnostics.
Our goals are to make
• A more transparent network operations
• Rapid problem identification and reporting for immediate resolution
• Improved efficiency in network information management with creditable findings
• Delivering faster and better decision making
• This leads to more transparent network operations to the end user.
