MPLS Concept

XL go MPLS

Excelcomindo telah menjadikan solusi bisnis corporate sebagai layanan andalan pada tiga hingga lima tahun mendatang mengimbangi consumer solution yang menjadi bisnis inti saat ini.Solusi bisnis tersebut yaitu leased line, seluler, Internet, dan VoIP.

Sejak tahun 2005, XL telah mengembangkan IT-VPN. VPN yang dikembangkan perusahaan yang dikelolanya telah menggunakan teknologi terkini yakni MPLS (multi protocol label swicthing). MPLS dikenal sebagai teknologi dengan sekuritas paling tinggi.

XL merupakan operator selular swasta pertama di Indonesia yang beroperasi penuh sejak 1996. Jumlah pelanggan operator ini hingga akhir September 2004 mencapai 4,2 juta, atau ketiga terbesar setelah TSel dan Indosat.

MPLS vs E1

Kelebihan :
1. harga tidak di pengaruhi oleh jarak (jauh dekat sama)
2. kalo di dalam link kita ada voice, lebih baik pake
mpls, krn sudah di labeling,tapi kalo hanya data, ga perlu

Kekurangan:
1. krn jauh dekat sama harganya, maka kalo link kita dekat,
lebih baik pake E1

Di MPLS sendiri kebanyakan operator membagi dalam 3 service: Silver,
Gold, dan Platinum, mereka membagi berdasarkan jitter, dan latency.

MPLS dengan E1 tidak bisa disamakan.
Secara kualitas Leased Line lebih bagus dari MPLS

Kalo kebutuhan dalam pipa itu banyak yang akan dijalankan, mending
sewa E1 yg clear channel.
Kalo sewa E1 dng koneksi mpls, sering disebut ipvpn, ..tapi ga jamin
deh..Harga memang lebih murah ipvpn.

Kalo ga salah banyak operator sekarang ga mau nyewain E1 nya, mending
nyewain jalur dia yg IPVPN. Tapi masih ada loh yg mau nyewain E1. NAP mana coba coba?:D

MPLS components

MPLS comprises the following major components:

1. MPLS Virtual Private Networks (VPNs)—provides MPLS-enabled IP networks for Layer 3 and Layer 2 connectivity. Includes two major components:

1. Layer 3 VPNs—based on Border Gateway Patrol

2. Layer 2 VPNs—Any Transport over MPLS (AToM)

2. MPLS Traffic Engineering (TE)— provides an increased utilization of network bandwidth inventory and for protection services

3. MPLS Quality of Service (QoS)— buildings upon existing IP QoS mechanisms, and provides preferential treatment to certain types of traffic, based on a QoS attribute (i.e., MPLS EXP).

MPLS typologies

The MPLS protocol architecture has been constructed using the best parts of existing networking typologies.
For example, it includes the packet organization from Frame Relay, the file transmission size from IP, and the QoS goals from ATM. MPLS primarily deals with two important network efficiency aspects.

They are speeding up packet processing and establishing traffic-engineered paths within a network. MPLS uses a label switching technique to forward data through the network. The label-based switching is a technique based on an integration of layer 2 switching and layer 3 routing. This technique has been designed for high speed networks to use in a more efficient way that enhances performances of switching with the scalability and flexibility of IP routing. A small, fixed-format label is inserted in front of each data packet on entry into the MPLS network.

At each hop across the network, the packet is routed based on the value of the incoming interface and label, and dispatched to an outgoing interface with a new label value. The transition in label values defines the network path since the label is swapped at each Label Switched Router (LSR). Since the mapping between labels is constant at each LSR, the complete path is determined by the initial label value. Such a path is called a Label Switched Path(LSP). For efficiency, a Forwarding Equivalence Class (FEC) is defined which is a set of packets that has the same label value on entry to the MPLS network, and they will therefore follow the same LSP.

MPLS Intro


MPLS fits into the second layer of the OSI model, the network layer
and connects networking typologies by using the third layer, the Internet Protocol (IP) layer .

MPLS’s strength is that it integrates many different network technologies into a single interface with the IP layer, thereby simplifying and streamlining the connection.
