Hardware

• Processor
• Currently SUN (e.g., Netra T1 AC 200 or Fire
  V120)
• SS7 Stack
• Ericsson/Tieto-Enator SS7 PCI-boards (one for
  each host) that each supports two E1 links with
  up to 16 signalling channels
• Full SS7 redundancy (STP/SRP load sharing)
• Considering Ericsson Stack-on-a-Card SS7 boards
• Why Ericsson? Name!

Software

• Operating System
• SUN Solaris 8 (2.8)
• Additional software
• Ericsson SS7 stack
• Erlang OTP (including Mnesia)
• OpenSSL
• Application software
• Mainly Erlang OTP (drivers to SS7 stack in C)
• Full software redundancy with multiple hosts
• Current size approximately 5500 lines of C,
  130000 lines of Erlang and growing

jnets HTTP client and HTTP server

• HTTP client features include
• Syncronous/asyncronous request interface
• Persistent connections
• Pipelines
• Proxy support
• more (but lots missing also)
• Why jnets HTTP server?
• Backward compatible with inets 2.6
• Standards compliant
• Fast core, flexible configuration

15
jnets performance test

• Setup
• 1 client machine/1 server machine (847MHz, 128Mb,
  Linux)
• Client makes a new request immediately after a
  response was received
• Minimalistic settings (no logging etc)
• Tools
• httperf v 0.8
• autobench v 2.01
• Simple GET request against a small static HTML
  file.
• With cache (patch was needed for inets)

xmerl The Erlang XML processer

• Written by Ulf Wiger, now maintained at
  http//sowap.sourceforge.net
• Latest release xmerl-0.18
• Late developments
• Improved export functionality.
• Support of DOM and SAX style parsing of XML
  document
• Many bugfixes

22
ucs Erlang Unicode support

• Translates Unicode number to Mnemonic
• Converts from virtually any character sets to
  Unicode and vice versa, given that there exists a
  mapping!!
• Sometimes very slow
• Converts between IANA defined character set names
  and corresponding MIB number/character set
  aliases
• This does NOT give generic Unicode support in
  Erlang (strings etc)
