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).

Essentials of Automations: Exploring Attributes & Automation ParametersSafe Software
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.

19. Установка TCP-соединения (3-Way Handshake)
• Почему это важно?
– Установка правильной связи с использованием порядковых номеров и
подтверждений
– Обе стороны принимают соглашение об опциях соединения (WS, MSS и
SACK)
• Какие проблемы?
– TCP Slow Start
– Slow Start и congestion avoidance постоянно меняют скорость отправки пакетов
– Denial of Service Attacks
– TCP может использоваться для отправки пакетов, перегружающих систему (SYN
Flood)
20. Традиционные балансировщики и TCP

22. Традиционные балансировщики vs. NetScaler
Clients Internet NS Server
Соотношение клиентских и серверных соединений – 1:1 у традиционных балансировщиков
NS проксирует TCP-соединения, клиент и сервер полностью разделены; this allows a
NetScaler to Multiplex and Reuse server side TCP Connections.
Many Client Connections to 1 Server Side Connection N:1

31. Как работает GSLB?
1. Клиент производит DNS-запрос
What site should I go to?
2. NetScaler возвращает IP наиболее доступного ЦОД
Go to site number 3.
3. Клиент соединяется с указанным IP
Site 1
Site 2
Site 3
32. Варианты выбора политики доступа
• Round Robin
Взвешенный или не взвешенный
• Географическая близость
– Статическая или динамическая
• Уровень нагрузки
• Пользовательские политики
• Disaster Recovery
автоматический или ручной перенос нагрузки
• На базе сохранения сессии
33. GSLB Static Proximity
• IP локального DNS определяет его географическое расположение.
• Стандартные базы данные определяют ближайший балансировщик
• В географическом контексте имеются следующие обозначения:
“Continent”, “Country”, “State”,
“City”, “ISP”. Organization”
• LDNS IP может подходить под несколько политик
• Предлагается VIP с наилучшим набором параметров
• Сайты в том же ЦОД балансируются по взвешенному Round Robin
35. GSLB Communication b/w NetSclaers
Простой мониторинг
• Only State (Up/Down) is learned
• Status is assumed to be equally good
• Each DNS query gets the IP address of various participating GSLB sites in a round robin
fashion.
• Insecure mode of Communication
MEP (Metric Exchange Protocol)
• NetScaler internal protocol to exchange state and health information over a TCP session
• Connection establishment involves a secure RPC method
• Data is sent in an non-encrypted manner
• DNS queries get best suited response based on configured algo and information gathered
through MEP
36. GSLB Dynamic Decision Methods
• RTT (Round Trip Time)
• Least Connections
• Least (Server) Response Time
• Least Bandwidth
• Least Packet
• Source IP Hash

41. Сжатие HTTP
Зачем сжимать данные HTTP?
Меньше пакетов проходят по сети
Быстрее ответ приложения
• Большинство веб-контента хранится несжатым
• Все браузеры поддерживают сжатие GZIP
– Совершенно прозрачно для пользователей
– Решение о сжатии принимается на основе заголовка User-Agent
– Политика NetScaler определяется по User-Agent и MIME-Type
• Обычное сжатие – в интервале от 3:1 до 5:1
• Сжатие данных на скоростях до 6 Gbps
