TECHtionary.com Analyzes SIP-Sim - SIP Simulator from RADCOM13 July 2005
SIP-Session Initiation Protocol is one of the key signaling protocols used in IPT-Internet Protocol Telephony or VoIP-Voice over Internet Protocol. Critical to adding voice to an existing data network is ensuring a high level of performance. Simulating and testing carrier and enterprise level networks is an important to maintaining and improving performance now and in the future.
Data networks can be bursty, with packets arriving in large, unpredictable chunks that often cause "traffic jams." These traffic jams often slow your Web response times significantly and adverse impact real-time voice and video applications.
This means that certain large file email attachments, web surfing and other applications create an "unequal" balance in the way the network processes data which reduces network performance. With the introduction of VoIP-Voice over Internet Protocol networks, this congestion can now interrupt voice communications as well as data traffic, causing "stutter" delays and "voice skips."
These skips are a result of too much data traffic on converged voice and data networks. Most networks are engineered to handle the traffic when users are being well-behaved, however recent increases in P2P-Peer-to-peer traffic, streaming video, or high volume printer traffic, can quickly throw a well designed network into gridlock. Testing assures no degradation in functionality under device specifications including:
- QoS-Quality of Service
- Delays
- Jitter ( explained in TECHtionary under Jitter )
- Packet loss
- MOS-Mean Opinion Score ( explained in TECHtionary under MOS )
- Stability ( in-path device )
- Interoperability
- Benchmarking and comparisons
SIPSim, from Radcom ( www.radcom.com ) generates different levels of stress including RTP-Real-Time Protocol and Voice and video simulation. SIPSim-MediaPro provides signaling and media analysis and voice quality ( intrusive, non-intrusive, and subjective ) with connections to Ethernet, OC3-Optical Carrier Level 3, and WAN-Wide Area Network interfaces.
An optional QPro connects to PSTN-Public Switched Telephone Network interfaces and measures voice quality, voice distortion and other factors.
The underlying SIPSim generates:
- Different levels of stress
- Different services
While, SIPSim-MediaPro provides QoS analysis of:
- Voice quality
- Delays ( setup duration and jitter )
- Packet loss
That is, various call flow scenarios can be explored including customer created unique call flows. In summary, SIPSim is a highly advanced SIP testing engine and simulation system. SIPSim can test under stress in the form of a load-generator tens to tens of thousands of users with all kinds of applications.
SIPSim gives the network planner tools for any kind of simulation including a SDK-Software Development Kit to totally-custom the product for an existing or proposed network.
