Expert Analyzer

No matter what your traffic level is, Network Analyzer transorms data into mean-ingul diagnostic inormation, constantly monitoring the traffic on your network.Te Expert Analyzer reduces thousands o rames to a handul o significant events.It watches continuously or router misconfigurations, slow file transers, inefficientwindow sizes, connection resets, and many other problems. It does this or eachprotocol stack you have running (including IPv6); all in real time as events actuallyoccur.

Alert events indicate a serious network problem, such as zero time to live in IP.

Warning events highlight a configuration or perormance problem in the network,such as connection reused in Oracle, then list all possible reasons or the reusal.

Normal events give inormation on normal network transactions, such as OSPFrouter identified and provide statistics on the IP and MAC addresses as well as thenumber o OSPF routers identified.

An additional drill-down capability enables you to ocus on the data, discover thesource o the problem and find a recommended solution.

Data Filtering

Te J6801B DNA, J6802B DNA MX, J6803B DNA PRO, and J6872A 10 Gigabit/Gigabit Ethernet Blade Interace support two types o data filtering to assist introubleshooting and analyzing the large quantities o data generated on a high-speed link: capture and display filters. Hardware-based capture filters allow theuser to speciy which data the instrument should store in the capture buffer or ana-lyze in real-time. Sofware-based display filters let the user speciy which capturedrames should be shown on the display.

Te acquisition system used in the J6801B DNA, J6802B DNA MX, J6803B DNAPRO and J6872A 10 Gigabit/Gigabit Ethernet Blade Interace allows 100% o alldata via any interace to be captured (ull-duplex), regardless o the link speed,link utilization, or errors; the specialized hardware will catch everything. Ofen,the data o interest occurs rarely; even large capture buffers can fill quickly, par-ticularly rom higher rate interaces. Te data acquisition system has sophisticatedhardware capture filters so that capture memory is used with maximum efficiency,avoiding the capture o vast amounts o data o no interest. Tese capture filtersconsist o 32 simultaneous hardware protocol filters (each 256 bytes wide) andare in addition to hardware filters in the LIMs that can also filter traffic by AMVPI.VCI labels. Tese capture filters operate on all data entering the acquisitionsystem, whether or not the data is to be captured or analyzed in real-time. Onemeasurement that operates on data beore capture filtering is the Protocol Vitalsmeasurement.

Any number o hardware filters may be active at the same time; multiple activefilters are logically ORed. Network Analyzer allows you to set up filters by rameattributes. For example, when filtering LAN traffic, filters can be specified to filterrames with a bad rame check sum (FCS), runts (collisions), jabbers, dribbles, orthe data portion o the packet. When filtering by data, up to 64 bytes may be speci-fied in the data field ollowing the MAC source and destination addresses as filtercriteria or network layer or IP filters.

TCP Connection Analyzer

Easily analyze CP connections and quickly troubleshoot and identiy CP connec-tion issues. With this measurement, you can examine CP flow control, messaging,response times, window sizes, retransmissions, payload statistics, and other CPcharacteristics. Tis is an off-line measurement perormed on captured data.

The statistics shown for each TCP connection are:

average acknowledgement response times

total packets sent rom a port (host)

total bytes sent rom a port (host)

average bytes per packet sent rom a port (host)

bytes per second sent rom a port (host)

good bytes per second sent rom a port (host). Tat is, the portion o the connec-tion bandwidth sent rom a port that is not associated with retransmitted packets.

Multi-segment jitter, latency, and packet loss

Quickly identiy degradation points across a network. Use the IP multi-segmentjitter measurement to detect and report jitter, packet loss and latency across multipleNetwork Analyzer data capture files rom a distinct communication path across anetwork. Tis measurement supports IP, ICMP, CP, UDP and RP networks. Tis isan off-line measurement perormed on multiple capture files.

Measurements include:

total jitter (min, max, and average) in each direction

network jitter (min, max, and average) in each direction

source jitter (min, max, and average) in each direction

packet loss in each direction

latency (min, max, and average) in each direction.

Run-time store to media

Do you need to collect and analyze traffic over extremely long periods or have anintermittent problem that is hard to capture? Te DNA platorm lets you collect andanalyze data over long periods by utilizing unique data streaming capabilities. Inrun-time store to media (RSM) mode, the instruments streams data in run-timethrough external ports or post analysis and troubleshooting.

Te J6801B DNA, J6802B DNA MX and J6803B DNA PRO can stream to media upto 55 Mbps using the Control and Sync port. By utilizing a dedicated gigabit Ethernetport, the J6801B DNA and J6803B DNA PRO can stream up to 150 Mbps.

Encapsulation discovery

Network Analyzer takes care o handling tunneled or encapsulated LAN traffic.

Sophisticated algorithms discover the encapsulation used on the link under test andwill configure the system or you. Simply type in the IP address or the application youwant to filter on and the sofware will take care o the encapsulation that the networkdevices are using. You can also define a filter based on the discovered encapsulation.GRE and GP tunneling is supported. All measurements and analysis are done at thehighest IP level.

Protocol commentators

At the heart o Network Analyzer is a series o commentators, which perorm real-time protocol state-ollowing analysis o rames to detect anomalous protocol events.Tese events are logged and linked to the corresponding captured rames, makingit easy or you to scroll through the capture buffer to see the events that led up to ananomalous event and then drill down into the event itsel. Commentators or many

different protocol amilies, including IPv6 and VoIP, are included.One o the most important capabilities o the protocol commentators is the abilityto detect potential problems in the network, and provide a suggestion o what to doto solve the problem, in addition to an explanation o the actual problem and tech-nology behind it. You do not have to be a network expert to detect, understand, andtroubleshoot problematic networks.

Figure 15. Commentators allow you to automatically detect problematic issues in the network and

obtain possible solutions to the problems

Te data is displayed in a tabular or graphical ormat and can be viewed by Hub/Node, DE/DCE or LN/EQ activities depending on the link-layer technology used,to provide:

% utilization

total number o rames and bytes

rames and bytes per second

DLL (data link layer) errors

errors per second

average rame length.

Te statistics can be logged to disk and may be exported in CSV ormat or JDSUNetwork Analyzer file ormat. Tis data can then be used to generate proessional-quality reports with the J6848A Report Center sofware.



Protocol statistics

o help understand variations orame length and protocol usage overtime, protocol and rame length sta-tistics are gathered simultaneouslyor the network layer and the majorprotocol stacks. Network Analyzerdisplays these statistics in both tabularand pie chart ormat, showing per-centage utilization or rame lengthdistribution by protocol. Ethernet,Frame Relay, and reassembled AMrame lengths are displayed in the ol-lowing categories:

< 64 bytes

64.127 bytes

128.255 bytes

256.511 bytes

512.1023 bytes

1024.1518 bytes

> 1 518 bytes

Figure 16. Frame Length by protocol is one of the multiple ways to view the information

Node discovery

Maintaining an up-to-date list o network nodes is key to managing many networkproblems as they occur. Network Analyzer provides an open node list that is auto-matically incremented as new discoveries are made by the node discovery algorithm.

Te node list shows MAC or bridged WAN addresses, network addresses and nodenames. Node Statistics reports use the station and server node names extensively,making node identification easier and aster. As a result, the Network Analyzer sof-ware provides useul clues to solving network problems.

Baselining

Network Analyzer lets you collect statistical inormation over long periods andexport it to the J6848A Report Center sofware to generate management-levelreports. Armed with these reports, you can easily identiy network trends and planor uture network requirements. Te two most important measurements or this ea-ture are the Protocol Vitals and the Connection Statistics measurements.

Te Protocol Vitals measurement is one o the undamental measurements in thesystem.

It gives you a real view o the network, even i capture filters are active.

Te measurement collects a wealth o protocol-specific inormation on various pro-tocols like AM, Ethernet, Frame-Relay, IPv4, IPv6, Apple alk, IPX, OSI etc., plusline status (WAN/AM interaces).

You can select the inormation you want to graph without having to stop or restartthis or any other measurement. Tis selection makes it easy to identiy correlateddata patterns like broadcast rames versus routing packets versus Frame-Relayrame-rate, etc.

Te measurement monitors thresholds that you can easily set dynamically to detectintermittently occurring events automatically and stop the capture process or ur-ther analysis, even i the system is running unattended.

Te Protocol Vitals measurement graphs current and maximum utilization in real-time and provides current, average, peak and cumulative values in tabular ormat othe ollowing parameters:

Protocol Vitals

While the analyzer is decoding data, itis also gathering important inorma-tion rom the network. Tese networkperormance statistics can beaccessed with just a click o the mousebutton and may be viewed simulta-neously with the decoded data. TeProtocol Vitals measurement pro-vides a statistical picture o the lowerlayers and the various protocol stacksto show cumulative data and trendsover time. You can use these statistics

to identiy problems or assist in opti-mizing your network configuration.

ATM policing

Te policing measurement operates in real-time with all AM-capable LIMs upto 622 Mbps, including IMA and AM channelized sub-rates o the J6810B SDH/SONE LIM. In all cases, policing is perormed on up to 1024 virtual circuits simul-taneously. Virtual circuits are auto discovered and the measurement is perormed inhardware prior to hardware-based AAL-2/AAL-5 reassembly, so it works in cell modeor rame mode. It can be used simultaneously in real-time with other measurementssuch as the VPI.VCI statistics and, in rame mode, with higher layer analysis. Temeasurement can also be used to post-process data rom the capture buffer or romfile (cell mode only).

The following traffic service configurations are supported:

CBR.1/DBR/UBR.1 GCRA (1/PCR0+1, CDVT0+1), no tagging

VBR.1/SBR1 GCRA (1/PCR0+1, CDVT0+1)

GCRA (1/SCR0+1, BT0), no tagging


GCRA (1/SCR0, BT0), no tagging


GCRA (1/SCR0, BT0), tagging

AM VPI.VCI provides results in a table ormat. Configuration o the traffic contractparameters can be perormed globally, in ranges o VPI.VCI or individually per VPI.VCI. Te configuration can be saved and restored rom file.

ATM Usage Expert

Te network has traffic contracts set up to protect it rom excessive traffic and thedanger o congestion. However, how close is your traffic to the contract limits? Tisuseul measurement is able to derive suitable traffic contracts or actual constant/deterministic bit rate (CBR/DBR) and variable/statistical bit rate (VBR/SBR) trafficby post-processing data rom the capture buffer. Te estimated traffic contracts canbe subsequently applied to live real-time policing analysis on the same virtual circuitin cell mode or rame mode to confirm that this is a suitable traffic contract over thelonger term.

1-Point CDV graphing

A side effect o the policing measurement is the ability to graph 1-point cell delayvariation (that is, CDV observed at a single point). Te graph is derived rom the datacollected per virtual channel o cell inter-arrival times. For each virtual channel, themeasurement keeps multiple bins o accumulated counts o inter-arrival times that

occur within the ranges covered by these bins. Te graph can be plotted as a distribu-tion o hits against inter-arrival times or hits against cells/second. As a non-intrusivepassive measurement on live traffic, this is particularly useul or observing the behav-ior o CBR/DBR traffic where CDV can impact the quality o service o the emulatedcircuit being carried in the virtual channel. Tis measurement is perormed simulta-neously with other policing measurements and a graph o any policed virtual circuitcan be displayed at any time.

Active tests: traffic generation and packet editing

Built into the Network Analyzer sofware is a powerul traffic generator to addadvanced traffic generation and intelligent packet or capture file-editing capabilities.Ideal or installation testing and or manuacturing test and support organizations, itprovides the tools you need to thoroughly test, simulate and troubleshoot a networkdevice or problem. Network Analyzer provides intelligent packet and capture buffer fileediting or ull 7-layer customization o data to be transmitted. While you speciy ramerate, burst count, or percent utilization, the sofware automatically calculates inter-packet gaps or various traffic loads, calculates the checksum and generates a CRC.

You can quickly configure Network Analyzer to generate a single packet such as anARP or PING to troubleshoot a production network and veriy connectivity or togenerate a series o packets to saturate a test network and test new equipment and con-figurations beore network deployment.

The multitasking capabilities of Network Analyzer let you monitor the network while the

traffic is generated including: perorm active stimulus/response tests to troubleshoot a production network

test new equipment or configurations beore deploying them in the network

generate higher layer traffic over any Ethernet interace up to 10 G or any AMinterace (except IMA and AM25) up to 622 Mbps AAL-5 segmentation is per-ormed automatically. AM cell mode generation is also available.

For AM, the user is allowed to create either a set o cells, or a set o rames or transmis-sion onto a network.

For each frame or cell in a transmit set, users have the option to:

start with pre-defined templates (IP rames or cells), or

start with rames or cells previously captured on AM networks, or

create their own rames or cells.

In AM cell mode, templates are available or the creation o AAL-5 cell sequencesand F4 and F5 AM layer OAM cells. I the VPI.VCI is 0.0, templates or F1 and F3physical layer OAM cells or IMA ICP/filler cells are available.

In AM rame mode, the traffic generator rame builder allows AAL-5 rames andAM cells to be built. I cells are selected, the choice is the same as or cell mode abovebut i rame mode is selected, the rame will be encapsulated (RFC2684/RFC1483-routed) and AAL-5 segmented appropriately.

ICMP Echo (Ping)

Tis active measurement is currently available or LAN and AM. LAN Ping operatesvia any o the 10/100/1000 and 10 GE interaces and AM Ping operates via any o the

AM interaces except IMA.

Te user can speciy the source and destination IP addresses, the number o ICMPdata bytes, the time-out period, and in the case o AM, the VPI.VCI value and encap-sulation method.

Measurement logging

Measurement logging is available to store test results in a disk file. You can select log-ging or all the open measurements rom a common dialog box. Data may be logged inone o two ormats, CSV and Network Analyzer *.dat. All data are stored into files thatcan easily be opened by the J6848A Report Center sofware or the Network Analyzerapplication.
