Beyond HTTP, Breaking Free of The Web Mark Wolfe
–From http://www.w3.org/DesignIssues/Architecture.html “The most fundamental specification of Web architecture, while
one of the simpler, is that of the Universal Resource Identifier, or URI.”
–From https://tools.ietf.org/html/rfc2616 “The Hypertext Transfer Protocol (HTTP) is an application
protocol for distributed, collaborative, hypermedia information systems.”
– From http://en.wikipedia.org/wiki/Application_programming_interface “In computer programming, an application programming interface
(API) is a set of routines, protocols, and tools for building software applications.”
APIs We Use != http DNS Used to resolve host
names Also used for service discovery MDNS SPDY
Wireshark Network protocol analyser Our window into the wonderful world
of protocols and APIs Available for Windows, OSX and Linux https://www.wireshark.org/ The wire doesn’t lie
DNS? Protocol uses UDP or TCP for transport Consists of
Questions and Answers Includes some information on authority Uses "intelligent retransmission” Small messages
DNS Continued.. Binary protocol Fixed header Payload uses a compact
self describing binary format TLV (type length value)
DNS Question
DNS Answer
DNS Exchange
HTTP Get Request
In Review Compact messages More likely to transit “wireless” networks
Extensible self describing binary payload Established encoding so others can introspect without a definition! Fast
MDNS Uses UDP Over Multicast Designed for resolving names in
adhoc networks Uses the existing DNS message structure, name syntax, and resource record types
Something Simpler? So lets look at something simpler than DNS
What if we just put text in a UDP packet What would that look like?
Problem I want to send 10s of 1000s of metrics
to a server for aggregation with minimal performance impact I want to keep it simple I want the server to be a staging area for data Perform Aggregation Flush to timeseries at regular intervals
statsd Developed by etsy Uses UDP as a transport Data
is encoded using text Metrics are either a Gauge, Counter, Timer or Meter No reply necessary!
statsd protocol Metrics are generally of the form <metric name>:<value>|<type>
outside_temp|12.2|g get_home_request_time|123|ms get_home_request|1|c
In Review Very simple implementation Doesn’t block Fast Loss doesn’t
really matter in the scheme of things Maths happens in the server
None
