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!

19 November

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

19 November

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

19 November

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)
