Defining SIGTRAN

dd40

SIGnaling TRANsport (SIGTRAN) is a standard inwhich traditional signaling protocols are transported on

IP networks.

SIGTRAN is the name of a workgroup assigned by theInternet Engineering Task Force (IETF) to develop

standards to govern the transport of signaling

information over IP

uses new protoco s or a apt ng s gna ngapplications for Voice-over-IP networks to the PSTN SIGTRAN is a logical extension of the SS7 protocol

SIGTRAN implements the SCTP protocol, which is a peer to TCP and UDP, but has


.

MTP3 functionality from the SS7 stack.

IETF is an open standards organization supported by ANSI, ITU and ISO and is tasked to

provide standards for all aspects of Internet communications.

For further information on SIGTRAN, refer to RFC 4960

.

SIGTRAN is based on the IP protocol replacing long-haul, point-to-point SS7 links between

network elements with IP connectivity.

The IP packets ride on the Streaming Control Transport Protocol (SCTP). SCTP is message

oriented. The protocol transports data through a sequence of messages as opposed to an

unbroken stream of bytes as in TCP (Transmission Control Protocol).

Message Flow

In general, the steps for a message flow in an SS7 over IP network are:


1. A MSC/SSP generates an SS7 MSU (Message Signaling Unit) and sends it to theEAGLE.

2. THE MSU is routed through the EAGLE to the network SIGTRAN interface card (E5-ENET).

3. SIGTRAN places the SS7 MSU in the Data Field, builds the IP packet header andsends the message out through the Ethernet port.

4. SCTP uses the IP Address and port in the header to determine the source anddestination of the packet.

5. The IP packet is received at the destination STP.

6. The receiving SIGTRAN card extracts the SS7 MSU from the Data Field.7. Using the Destination Point Code, the MSU is then routed to the next linkset and

delivered to the intended destination.

To optimize the performance of your network, evaluate the unique requirements andcharacteristics of your SS7 IP network when provisioning the EAGLE. Consider thecharacteristics at the IP layer of your system as well as the performance objectives of yourEAGLE STP.

Characteristics of an IP Network


Characteristics of an IP Network are those factors resident with the IP layer of the network

and external to the EAGLE. These characteristics affect your network performance and

provide information critical in determining how best to provision your EAGLE for optimal

performance. Bandwidth for example, is a limited resource. The amount of available and

required bandwidth is determined by several factors including IP network characteristics.

These characteristics include, but are not limited to:

The design of your network dedicated or converged

Speed and Duplex

RTT calculations and stability

RTT (Round Trip Time)

Round Tri Time is the ela sed from when a messa e is sent to an ad acent node to when


the ACK is returned. RTT is the time needed for one full transaction.

RTT is calculated at two levels. The IP layer (ping) and the SCTP (Association) layer. TheRTT calculation at the SCTP layer is related to the provisioned association. Typically, theRTT at the SCTP layer is greater than that of the IP layer due to the additional processingneeded to operate on the SCTP data.

A stable RTT is one of the most important characteristics of your network. An unstable RTT,such as a RTT with consistent spikes, will cause bandwidth issues and jitter. SCTP timingparameters are based on RTT values.

Management and control of these IP characteristics are outside the scope of the STP.However, the Tekelec EAGLE provides methods by which to manage the variability of IPnetwork characteristics. For example, Tekelec recommends capping traffic capacity at 40%.

IP Addressing Overview


An IP address uniquely identifies a given network and may identify a given node within the

network.

An IP address consists of two main fields. The Network Address portion provides a unique

identification for the network. The Host Address portion identifies a specific host or node

within the network.

Each SIGTRAN card has two physical interfaces (Ethernet port A and Ethernet port B)

IP addresses are assigned to the SIGTRAN (E5-ENET/E5-ENET-B) card, not the STP.


All IP addresses related to the network for port A must belong to a different network than

the addresses for port B. (Using port B is optional).

Notice that the SIGTRAN card port must have the same network address as the router for

that network.

E5-ENET or E5-ENET-B cards must communicate to Ethernet Switches (one per physicalinterface).


The local Ethernet network delivers packets to a Wide Area Network (WAN) which delivers

the packets to a distant Ethernet Local network.

The distant IP Endpoint might be another STP or it might be some other IP signaling

device.

SIGTRAN treats each MTP3 link as a separate application (program).

The logical path from one MTP3 link at the near end to one MTP3 link (or its equivalent) is

called an association

SIGTRAN Applications on the EAGLE

Tekelec has three SIGTRAN implementations:

IP Signaling Gateway (IPSG) which is a combination of

both the legacy IP Link Interface Module and the IP

a eway mp emen a ons. e ea ure o ers mprove

monitoring and performance.

IP Link Interface Module (IPLIM) which provides point-to-

point connectivity between EAGLE STPs

IP Gateway (IPGW) which provides point-to-multipoint

connectivity from the EAGLE STP to centralized databasesand/or Media Gateway Controllers

NOTE: IP Signaling Gateway requires EAGLE Release 38.0.1 and above.



21/119

SIGTRAN Adaptation Layers

The SIGTRAN Adaptation Layer maintains SS7 concepts (e.g.

alignment) while using SCTP as a transport mechanism.

Tekelec has implemented two SIGTRAN protocols with IPSG:

M2PA (MTP2 Peer-to-peer Adaptation layer)

Replaces B, C & D links between STPs

M3UA (MTP3 User Adaptation layer)

-

SIGTRAN protocols are encapsulated inside the Data Chunks

of the SCTP protocol.

SIGTRAN Adaptation Layers

The Data Chunk carries the Adaptation layer. The Chunk will consist of a SIGTRAN


.

SIGTRAN protocols:

M2PA MTP2 Peer-to-Peer Adaptation layer

M3UA MTP3 User Adaptation layer

NOTE: SUA (SCCP User Adaptation) layer is NOT supported in IPSG.

SCTP Associations define:

The local SIGTRAN card IP address and SCTP port

SCTP Connections support:

Multi-homing

Multiple streams

SIGTRAN uses SCTP as a transport protocol.

RFC 4960 describes the SCTP Protocol


SCTP connections are defined (provisioned) as an Association between two endpoints.

SCTP connections support multi-homing.

Each connection can have multiple Streams.

Each stream can support multiple data chunks.

Four SCTP Streams


Streams provide multiple segregated paths in the same association. Streams are defined

separately by direction inbound / outbound. The number of inbound and outbound

streams is defined per association.

Though RFC 4960 allows for multiple streams, a maximum of two inbound and two

outbound is supported by Tekelec. The creation of associations default to 2 inbound and 2

outbound streams.

This four stream architecture optimizes:

Synchronization between data streams

Synchronization from control stream to data streams

Load-sharing implementation based on Signaling Link Selection (SLS) across

streams.


34/119

Associations

Associations define the IP addresses and SCTP port numbers

for both the local and remote host.

The core data for an association is the TUPLE.

1. lhost, alhost, lport, rhost, rport

2. Multi-homing is implemented by providing a value for the

alhost parameter.

Multi-homing offers an alternate route/address that can be

used for communication with the remote host.

3. Other important parameters of the association:

Association name, and the Adaptation layer

Each association has a unique name.

All other commands reference the association by the association name.

implement multi-homing. The Local Host and the Alternate Local Host must be

defined as different Ethernet Ports of the same SIGTRAN card.

6. Arhost (Alternate Remote Host) An alternate remote name that represents the

IP address of the alternate remote host used in multi-homing.

Multi-homing provides an alternate communications path in case the primary path fails.


When SCTP initializes a connection, it will offer the local host and the alternate local host

(if provisioned) a usable IP address.

The response from the remote end will list its local host and alternate local host as usable

IP addresses.

If the Primary path fails, the SIGTRAN card will switch to the port for the alternate localhost and transmit packets to the alternate IP address for the remote.

m3ua uses A linkset type only

:adapter m2pa or m3ua

:ipsg=yes for IPSG linksets

slktps the number of transactions per second (TPS) that is assigned to each IPSG signaling link thatwill be in the linkset, from 100 to 5,000.

lsusealm specifies the percent of the linkset TPS at which an alarm is generated to indicate thatthe actual linkset TPS is approaching the configured iptps value for the linkset

slkusealm specifies the percent of the link fair share TPS at which an alarm is generated toindicate that the actual link TPS is approaching the links fair share of its linksets configured TPS(iptps). The fair share of the linkset TPS for a link is the configured linkset TPS divided by thenumber of in-service links in a linkset.

Setting Linkset TPS Thresholds

Example: A link set that has 4 links in the link set. The

slktps is set to 1000 tps. LSusealm is set to 80%,slkusealm is set to 60%

Links in

Service

LS Usealm

(0115)

SLK Fair

Share

SLK Usealm

(0116)

4 3200 1000 600

2 3200 2000 1200

1 3200 4000 2400

Alarm 0116, slkusealm trips when the transactions across at least one link in a link set exceed thesignaling link fair share value.

The signaling link fair share is the sltps times the number of links in a link set.


Lets take an example where we have 4 links in a link set. It does not matter whether the links areon the same card or not. The slktps is set to 1000, lsusalm is set to 80%, the slkusealm is set to 60%

Example 1: (First row on table above) All links are in service. The total Link Set tps= 1000tps/slk * 4slks= 4000 tps. The link set will trip alarm 0115 if the total tps in the link set exceeds 4000tps/ls *80% = 3200 tps. The slk fare share is 4000 tps/ls div 4 links = 1000 tps. The slkusalm will trip at60% of the fare share (1000tps/slk * 60% = 600 tps.)

Example 2: (Second row on table above): One link is out of service. The lsusealm still trips at 3200tps, but now the slkusealm doesnt trip until 800 tps.

In this way, as two links go out of service, the lsusealm is still 3200 tps, but now the slkUsealmdoesnt trip until 1200 tps.

With three links out, lsusealm is still 3200 tps, but the slkUsealm is way up at 2400 tps.

physical Ethernet port.chg-assoc : < command to modify association >

aname = aralncenet1107a : < repeat from en-assoc >

alhost = clay1nc.e5enet.1107b : < must be opposite port to lhost >

rhosttype= alternate < means rhost (above) is arhost >

rhostval=match < see notes >

Note: The lport values must be unique between multiple associations on

the same port.

The chg-assoc command can be used to provide the alternate path to fail over to if theprimary path fails


.

rhosttype = alternate says that the rhost this time is an alternate host, not a primary host.

rhostval can have any one of two values

relaxed The remote host can be negotiated when the association is established. If

the other end offers a new rhost, use that one. If you set this mode, then rhost and

rhosttype are both optional. The drawback to this mode is that if the primary path

fails and the association goes down, it cannot come back up on the alternate path.

match (Sometimes known as strict mode.) When the association comes up, the

other end must offer this host IP address as the alternate. If it does not the link

cannot come up. The other end must be RFC 4666 compliant for this mode to work.

The advantage of this mode is that if the primary path fails, the association can go

down and come up on the alternate path. If the primary path fails, the alternate

Provisioning IPSG M3UA

Learning Activity 2: Provisioning IPSG M3UA

Documentation:

1. Use the IP7 Signaling Gateway and the Commands

sections of the user documentation set and the Student

Guide for help with any command or step in this lab.

Student Assignment:

1. Your assignment is to add IP connectivity to the assigned

AS and ASPs.



89/119


1. Login to your assigned STP

Login:uid=eagle

(password) eagle

2. Next we will do SS7 commands (ent-card, ent-dstn, ent-ls).

.

ent-card (loc, type, appl)

4. Before creating the destinations for the application server , check to see if the point codes

already exist. If not got to step 5.

rtrv-dstn

5. Create the destinations for the AS.

ent-dstn (dpc, cilli, bei, ipgwapc)

6. Enter the linkset the linkset for IPGW has several new parameters.

ent-ls (apc, lst, lsn, adapter, ipsg, slktps, lsusealm=80, slkusealm=80)

apc specifies the adjacent point code

lst = specifies the linkset type

lsn = specifies the linkset name

adapter - specifies the adapter layer for links provisioned in a IPSG linkset

ipsg - specifies whether a linkset is entered for an IPSG card.

s ps e nes ow muc o e sys em ransac ons per secon s ou e

allocated for this linkset)

lsusealm defines the alarm threshold for the linkset. Is a percentage of the iptps

parameter

slkusealm defines the alarm threshold for each link. Is a percentage of the iptps

parameter

7. Change the IP Link parameterschg-ip-lnk (loc, port, ipaddr, submask=255.255.255.0, duplex=full, speed=100, auto= no,

mcast=no, mactype=dix)


90/119


8. Enter Host Names for the IPSG Ethernet port, IP address and type ( there will two entries, one for the

local host, and one for the remote host

ent-ip-host (host, ipaddr, type)

9. Change the IP card parameters

chg-ip-card (srchordr=local)

10. Enter the associations for the IPSG two ASPs

ent-assoc (aname, lhost, lport, rhost, rport, adapter=M3UA)

11. Enter the Network Appearance

ent-na (na, type)

The na will be1 for the ASPs associated with the assigned network

enter once for the ASPs associated with the assigned network, i.e. Raleigh/Clayton, Dallas/Hubbard,

Denver/Salt lake, or Heathrow/Gatwick.

13. Enter a signaling link on the SIGTRAN card for the linkset created in step 9.

ent-slk : (loc, link, lsn, slc, aname*)

14. Enter the routes to the AS over the IPSG M3UA linkset

ent-rte : (dpc, lsn, rc=10)

15. Enable the BICC Control feature using the enable ctrl-feat command.

Partum=893018401

Fak=CFV9HRM55737C

16. Activate the BICC Control feature using the chg-ctrl-feat command.

This completes the IPSG M3UA setup. Time to put things in service.

17. Allow card, activate links, and open and allow associations.

a. alw-card (loc)

b. act-slk (loc, link)

c. chg-assoc (aname, open)

Note: If the value specified for the aname parameter refers to an M3UA

association on an IPSG card, then the alw parameter cannot be specified.

STOP! Notify your instructor you have completed the lab.

* aname value must match the entry in step 10.

Module 4 Review

1. Which parameter in the ent-ls command provides security by locking in an OPC,

DPC and SI? __________________

2. The ent-na command assigns a network appearance to a specific SIGTRAN card

provisioned in the Eagle STP. True or False

3. BICC guarantees faithful delivery of _______________________messages from

one MGC to another.

4. In IPSG M3UA, there must be one signaling link and association for every

___________ in the Application Server

5. In IPSG M3UA, the ent-slk command must come after the ent assoc command.

Command Completed

The rept-stat-iptps command is used to display the current and peak IPTPS usage for eachIPSG linkset in the system or for each link in the IPSG linkset


Reports on IPSG M2PA and M3UA

Command uses (Number of IS-NR links * SLKTPS) in place of the IPTPS setting for

all calculations and alarms.

If the linkset is specified with the peakreset=yes parameter, then the command

recalculates peaks for the specified linkset and resets all the stored peak values to

the current actual usage for each link contained in the linkset before reporting

usage.

Pass-through Commands

Introduction

Pass-through commands are passed through the OAMand sent to individual cards for processing.

Command ConventionThe following is an example of a pass command:

pass : loc = 1101 : cmd = ping 192.168.108.22

S ntax

Fixed portion: pass:loc=xxxx:cmd=Variable portion: The value for the cmd parameter can

be any of the pass commands. The value given to the

cmd parameter must be double-quoted.

Pass Command Syntax:

Inside the quoted portion, you dont use colons as separators

Copyright 2013, Oracle and/or its affiliates. All rights reserved.5 - 100

Inside the quoted portion, you dont use parameter=value pairs

See the Pass-through Commands chapter of the Commands manual of the user

documentation for a complete list of pass commands.


103/119

Pass-through Commands (contd)

Command OptionsMany pass command support options. The options aresingle characters prefixed with an hyphen (-). For

examp e, e p ng comman suppor an op on o con ro

the number of pings to perform and is entered as: ping

Verifying the Ethernet Interface Status

Verify the Status of the Ethernet Interface

1. rept-stat-card:mode=full:loc=XXXX This will show the status as either up or down and the assigned IP address.

2. pass:loc=XXXX:cmd=netstat -i

This is more detailed report of the Ethernet interface.

Is the cable plugged in? To the correct port?



105/119

Verifying the Local Ethernet Segment

Verify the local Ethernet segment.

1. pass:loc=XXXX:cmd=netstat d 0 for the A interface

2. pass:loc=XXXX:cmd=netstat d 1 for the B interface

Look for the following peg counters:

overflow

excessive collisions

alignment errors

crc

Indicates a local Ethernet settings mismatch, should be100/Full. Never use AUTONEGOTIATE.

Is the cable crimped? Cable defective?

Try a different switch/router port? Eagle card?



106/119

Verify the local Ethernet segment continued

1. Review the ARP cache of the EAGLE Card pass:loc=XXXX:cmd=arp -a

2. Review the routing table of the EAGLE Card

pass:loc=XXXX:cmd=netstat -r

Route Net Table = This is what is provisioned with the ent-ip-rte command

Route Host Table = This is what is provisioned automatically by the cards OS



107/119

Verifying IP ConnectivityVerify IP Connectivity

Verify IP Connectivity

1. Can you ping the network gateway for each of the cards

IP interfaces?

Taken from rtrv-ip-card:loc=XXXX

pass:loc=XXXX:cmd=ping XXX.XXX.XXX.XXX

2. Can you ping the remote host?

Taken from:

rtrv-assoc:aname=XXXXXXX

rtrv-ip-host:host=XXXXX

pass:loc=XXXX:cmd=ping XXX.XXX.XXX.XXX

3. What about traceroute?

pass:loc=XXXX:cmd=traceroute XXX.XXX.XXX.XXX
