EXECUTIVE SUMMARY

1. In the Next Generation Telecommunication (LTE), all communication devices will use IP as the identity.

2. IP will be used to define routing from one node to others and vice versa. IP is the 3rd layer in OSI standard. Layer 3 (Network layer) is used to bring packet from one node to other using logical address (Packet Forwarder/routing).

3. Allocation of IPV4 is limited. Therefore plan is needed and we can also divide IP network into some IP sub-network (subnetting)

4. IPv6 contain 128 bits (IPv4 only 32 bits). As the limitation of IP allocation, IPv6 will replace IPv4.

OSI LAYER

Application: End User Interface (http, ftp, telnet, dns, etc)

Data format sent: ASCII, binary, JPEG, other compression, etc.

Open, maintain and terminate communication session: SQL, netbios, RPC, etc

How to deliver data reliable or unreliable, connectionless (UDP) or connection oriented (TCP). It has function: error & flow control, sequence number, acknowledgement.

Change data from Data link BITS

Bring packet from one node to other using logical address (Packet Forwarder /Routing)

Communication data between one node and others using Hardware Address (MAC, LLC, etc). It identify the topology used (PTP, PTM – FR/ATM, BUS, Token Rng, etc). Also function for error control and flow control.

Internet Protocol Overview

From Wikipedia:

The Internet Protocol (IP) is the principal communications protocol in the Internet protocol suite for relaying datagrams across network boundaries. This function of ROUTING  enables internetworking, and essentially establishes the Internet.

Internet Protocol sends data packets with unreliable/connectionless (no warranty success or not)The responsibility is handled in upper layer.

IP V4

Communication between TCP/IP network needs identity known as IP address.

- IP address contain 32 bits.- IP address divided into Network ID and Host ID

- 32 bits IP divided into 4 parts, each part has 8 bits.- Every 8 bits can be converted to decimal 0 to 255.

Dec: xxx . xxx . xxx . xxx Bit : xxxxxxxx.xxxxxxxx.xxxxxxxx.xxxxxxxx

Note: IPv6 has 128 bit

25

IP V4 Classification

xxxxxxxx . xxxxxxxx . xxxxxxxx . xxxxxxxx

IP divided into 3 class

Class A:Network ID (8bit) Host ID (24 bit)0xxxxxxx xxxxxxxx.xxxxxxxx.xxxxxxxx

Class B:Network ID (16 bit) Host ID (16 bit)10xxxxxx.xxxxxxxx xxxxxxxx.xxxxxxxx

Class C:Network ID (8bit) Host ID (24 bit)110xxxxx.xxxxxxxx.xxxxxxxx xxxxxxxx

Note: IPv6 has 128 bit

- Network ID use binary 1- Host ID use binary 0

Netmask natural:

SUBNETTINGSubnetting diperlukan untuk membangun SUB-Jaringan dari Jaringan yang ada.Subnetting diperlukan untuk lebih mengefisiensikan/utilize alokasi IP address yang ada.

Tujuan Subnetting:

- Memadukan teknologi jaringan yang berbeda- Menghindari limitasi jumlah simpul dalam satu segmen- Mereduksi traffic yang disebabkan oleh broadcast atau pun collision

Jaringan di bawah ini bisa kita bagi menjadi beberapa sub-jaringan dengan menggunakan router.

192.168.1.0

192.168.1.1

192.168.1.2192.168.1.3 192.168.1.4

SUBNETTING

Dari gambar sebelumnya kita akan membagi IP jaringan 192.168.1.0 menjadi 4 buah sub-jaringan.

192.168.1.0 mempunyai Network ID = 192.168.1.0Broadcast ID = 192.168 1.255Host ID = 192.168.1.1-254

Karena ada 4 subjaringan maka langkah selanjutnya adalah memecah IP tersebut menjadi 4 bagian.

192.168.1.0 =11000000.10101000.00000001.00000000Karena 4 subnet = 22 maka jumlah bit untuk subnet = 2

11000000.10101000.00000001.00000000

Simplenya 256/4 ~= 64Sehingga didapat IP jaringan 4 subjaringan:- 192.168.1.0- 192.168.1.64- 192.168.1.128- 192.168.1.192

192.168.1.0

192.168.1.128

192.168.1.64

192.168.1.192

SUBNETTING

Sub Network 1Network ID = 192.168.1.0 =11000000.10101000.00000001.00000000Broadcast ID = 192.168.1.63Host ID = 192.168.1.1-62

Sub Network 2Network ID = 192.168.1.64 =11000000.10101000.00000001.01000000Broadcast ID = 192.168.1.127Host ID = 192.168.1.65-126

Sub Network 3Network ID = 192.168.1.128 =11000000.10101000.00000001.10000000Broadcast ID = 192.168.1.191Host ID = 192.168.1.129-190

Sub Network 4Network ID = 192.168.1.192 =11000000.10101000.00000001.11000000Broadcast ID = 192.168.1.255Host ID = 192.168.1.193-254

192.168.1.0

192.168.1.128

192.168.1.64

192.168.1.192

Exercise

1. Pada jaringan Class B & C dibutuhkan 50 subnet dengan masing2 dapat mempunyai 4 hosts.Berapa subnet bits yang dibutuhkan? Bisakah?

Class B (172.16.0.0 = 10110000.00010000.00000000.00000000)Karena 50 ~ 64 = 26 maka bit subnet yang dibutuhkan adalah 6 bit.Sisa 10 bits HOST10110000.00010000.00000000.00000000

Class C (192.168.1.0 = 11000000.10101000.00000001.00000000)Karena 50 ~ 64 = 26 maka bit subnet yang dibutuhkan adalah 6 bit.Sisa 2 bits HOST11000000.10101000.00000001.00000000

2. Dari data di atas berapa subnet-mask nya?

Ingat!! - Network ID use binary 1- Host ID use binary 0

Maka subnet-mask adalah:Class B: 11111111.11111111.11111100.00000000 = 255.255.252.0

Class C: 11111111.11111111.11111111.11111100 = 255.255.255.252

Exercise

3. Tentukan IP subnet/sub-jaringan dari Class B & C tersebut? Class B: 172.16.0.0 = 10110000.00010000.00000000.00000000172.16.4.0 = 10110000.00010000.00000100.00000000172.16.8.0 = 10110000.00010000.00001000.00000000172.16.12.0 = 10110000.00010000.00001100.00000000

:::

172.16.252.0 = 10110000.00010000.11111100.00000000

IP ROUTING IN BSC/RNC

- IP ROUTING (IPRT) should be created from BSC/RNC to other nodes to establish connection.- For checking whether connection is open between BSC/RNC with other nodes we can use PING command.- If no RTO found then we can create IP routing and UP/CP connection

DSTIP = IP SubnetDSTMASK = SubnetmaskNEXTHOP = IP router

INTERFACE IPWe can know how many BTS grouped in a VLAN from IPRT command.

For example, Abis IP is set from 10.48.x.x to 10.54.x.xFrom the CFGMML (LST IPRT) we got:

For IP Subnet=10.48.0.32, DSTMASK=255.255.255.224 (11111111.11111111.11111111.11100000) #HOST = 25 -2 = 32IP HOST/BTSIP = 10.48.0.32.0-62IP BROADCAST=10.48.0.63

Other example for RNC CFGMML:

For IP Subnet=10.176.2.0, DSTMASK=255.255.255.0 (11111111.11111111.11111111.00000000) #HOST = 28 -2 = 254IP NODEBIP = 10.176.2.1-254IP BROADCAST=10.176.2.255

IP BTS/NODEB/OAM NODEB

In Huawei we can check the IP address of BTS:

SET BTSIP:BTSID=0, IDTYPE=BYID, BSCIP="10.49.6.4", BTSIP="10.49.7.38", BTSCOMTYPE=PORTIP, HOSTTYPE=SINGLEHOST, CFGFLAG=NULL, BTSGWIPSWITCH=OFF;SET BTSIP:BTSID=1, IDTYPE=BYID, BSCIP="10.49.6.4", BTSIP="10.49.7.39", BTSCOMTYPE=PORTIP, HOSTTYPE=SINGLEHOST, CFGFLAG=NULL, BTSGWIPSWITCH=OFF;SET BTSIP:BTSID=2, IDTYPE=BYID, BSCIP="10.49.6.4", BTSIP="10.49.6.102", BTSCOMTYPE=PORTIP, HOSTTYPE=SINGLEHOST, CFGFLAG=NULL, BTSGWIPSWITCH=OFF;SET BTSIP:BTSID=3, IDTYPE=BYID, BSCIP="10.49.6.4", BTSIP="10.48.70.69", BTSCOMTYPE=PORTIP, HOSTTYPE=SINGLEHOST, CFGFLAG=NULL, BTSGWIPSWITCH=OFF;SET BTSIP:BTSID=4, IDTYPE=BYID, BSCIP="10.49.6.4", BTSIP="10.49.6.207", BTSCOMTYPE=PORTIP, HOSTTYPE=SINGLEHOST, CFGFLAG=NULL, BTSGWIPSWITCH=OFF;SET BTSIP:BTSID=5, IDTYPE=BYID, BSCIP="10.49.6.4", BTSIP="10.49.7.40", BTSCOMTYPE=PORTIP, HOSTTYPE=SINGLEHOST, CFGFLAG=NULL, BTSGWIPSWITCH=OFF;SET BTSIP:BTSID=6, IDTYPE=BYID, BSCIP="10.49.6.4", BTSIP="10.49.6.166", BTSCOMTYPE=PORTIP, HOSTTYPE=SINGLEHOST, CFGFLAG=NULL, BTSGWIPSWITCH=OFF;SET BTSIP:BTSID=7, IDTYPE=BYID, BSCIP="10.49.6.4", BTSIP="10.49.6.38", BTSCOMTYPE=PORTIP, HOSTTYPE=SINGLEHOST, CFGFLAG=NULL, BTSGWIPSWITCH=OFF;SET BTSIP:BTSID=8, IDTYPE=BYID, BSCIP="10.49.6.4", BTSIP="10.49.6.39", BTSCOMTYPE=PORTIP, HOSTTYPE=SINGLEHOST, CFGFLAG=NULL, BTSGWIPSWITCH=OFF;SET BTSIP:BTSID=9, IDTYPE=BYID, BSCIP="10.49.6.4", BTSIP="10.49.6.103", BTSCOMTYPE=PORTIP, HOSTTYPE=SINGLEHOST, CFGFLAG=NULL, BTSGWIPSWITCH=OFF;

IP CONNECTION for UP & CP

For User Plane, to deliver data in IP network between BSC & Other NE is set in below command:

IPADDR is IP address of Interface Port in BSC/RNCPEERIPADDR is IP address of Other NE (MSS, MGW, SGSN, GGSN, etc)

For Control Plane, connection will establish if Stream Control Transmission Protocol link is set.SCTP is Transport Layer protocol (same like TCP/UDP),

IP IN LTE

IPV6

IPV6 compared to IPv4 has some advantages:

- Larger address space (contain 128 bits), means 2^128 = 3.4 x 10^38 IP address can be defined- Multicasting
