IPNetSim™ Handheld
(Ethernet, IP, WAN Network Emulator)


Overview

GL's IPNetSim™ Handheld is a hand-held battery operated instrument that can simulate the real-time IP and Carrier Ethernet network dynamics by means of hardware controlled packet delay, loss, jitter, errors, bandwidth limitations, congestion, and duplication. IPNetSim™ Handheld offers to manage network behaviors of up to 1 Gbps rates with accuracy always better than 1ms.

IPNetSim™ Handheld is an invaluable tool for IP equipment manufacturers, R&D departments, Network Operators, ISP and Triple Play service providers that test and verify a wide variety of projects to determine whether a network application or device is appropriate for operation in such networks.

IPNetSim™ Handheld is equipped with hardware based impairments generator, and dual GbE ports, to emulate the dynamics of real Ethernet / IP networks.

Hardware Panel



Front and Back Panel - IPNetSim™ Handheld
  • Dual RJ-45 port for electrical connection (10/100/1000BASE-T)
  • Dual optical and electrical SFPs ports operating up to 1 Gb/s
  • USB and Ethernet ports
  • Serial Port RS-232C

Operation

IPNetSim™ Handheld is inserted between two Ethernet segments in pass through mode while operating in bidirectional packet transfer mode. The emulation settings can be defined independently for 16 separate flows that can be filtered by several criteria including MAC, IP, TCP/UDP or User Mask.


Traffic Impairments

  • Traffic impairments can be defined over max. 16 traffic flows
  • Independent criteria can be used over each branch
  • Actions: Packet loss, error, duplication, delay, reordering

Selective Traffic Filters

IPNetSim™ Handheld supports Ethernet, VLAN, IPv4 and TCP / UDP filters. Filtering is configured by first enabling one or several filtering blocks and after that setting the filtering criteria.

  • 16 user-defined filters to select flows based on MAC, IP, VLAN, TCP, UDP, COS, DSCP.
  • Agnostics filters defined by 16 bits masks and user defined offset

Traffic Statistics and Analysis

Tx Frame Analysis

  • Frames: Total number of frames transmitted by one tester port since the test started
  • Bytes: Total byte count transmitted by the test port from the beginning of the test. One byte is defined as an 8-bit word.
  • Broadcast frames: Total number of Ethernet broadcast frames transmitted from the beginning of the test. Broadcast frames carry the broadcast Ethernet address (FF:FF:FF:FF:FF:FF) in the destination field.
  • Multicast frames: Transmitted Ethernet multicast frames from the beginning of the test. Ethernet multicast frames have their multicast bit in their destination MAC address set to '1'. The multicast bit of a MAC address is the least significant bit of the more significant address byte.
  • Control frames: Total number of Ethernet MAC control and supervision frames transmitted from the beginning of the test. Ethernet control frames are recognized due to an special Ethertype (Type / Length field) value (0x8808).
  • Tagged frames: Total number of Ethernet VLAN frames transmitted from the beginning of the test. IEEE 802.1Q VLAN frames contain an special Ethertype (Type / Length field) value (0x8100).
  • FCS errored frames: Frames with FCS errors transmitted from the beginning of the test. An FCS errored frame may be the result of bit error insertion or a forwarded frame with a previous FCS error.

Rx Frame Analysis

  • Frames: Total number of frames received by one tester port since the test started.
  • Bytes: Total byte count received by the test port from the beginning of the test. One byte is defined as an 8-bit word.
  • Broadcast frames: Total number of Ethernet broadcast frames received from the beginning of the test. Broadcast frames carry the broadcast Ethernet address (FF:FF:FF:FF:FF:FF) in the destination field.
  • Multicast frames: Received Ethernet multicast frames from the beginning of the test. Ethernet multicast frames have their multicast bit in their destination MAC address set to '1'. The multicast bit of a MAC address is the least significant bit of the more significant address byte.
  • Control frames: Total number of Ethernet MAC control and supervision frames received from the beginning of the test. Ethernet control frames are recognized due to a special Ethertype (Type / Length field) value (0x8808).
  • Flow control frames: Total number of Ethernet Pause frames received from the beginning of the test. Pause frames are a special type of control frames and therefore their Ethertype is 0x8808. The specific features of Pause frames is that their Opcode field is 0x0001 and their destination MAC address is 01:80:C2:00:00:01 (a multicast MAC address).
  • Tagged frames: Total number of Ethernet VLAN frames received from the beginning of the test. IEEE 802.1Q VLAN frames contain an special Ethertype (Type / Length field) value (0x8100).
  • FCS errored frames: Count of all the FCS errors detected from the beginning of the test. A frame with a FCS error is a frame with a legal size which contains an invalid FCS field. FCS errors are caused by transmission errors. An optical Ethernet link with a poor power budget may experience FCS errors
  • Oversized frames: Total number of received frames which are larger than the configured MTU.
  • Undersized frames: Total number of received frames which are smaller than 64 bytes.
  • Jabbers: Jabber count from the beginning of the test. A Jabber is defined as a frame greater than 1518 bytes with a bad CRC.
