<strong>Migration</strong> Needs<br />
Growth <strong>of</strong> the company<br />
Yapi Kredi and Kocbank merged. All the branch <strong>of</strong>fices <strong>of</strong> old<br />
Kocbank needed <strong>to</strong> be migrated <strong>to</strong> the <strong>network</strong> infrastructure <strong>of</strong><br />

What <strong>MPLS</strong> brings<br />
Multipro<strong>to</strong>col Label Switching (<strong>MPLS</strong>) enables Enterprises and<br />
Service Providers <strong>to</strong> build next-generation intelligent <strong>network</strong>s that<br />
deliver a wide variety <strong>of</strong> advanced, value-added services over a<br />
single infrastructure<br />
Subscribers with differing access links can be aggregated on an<br />
<strong>MPLS</strong> edge without changing their current environments, as <strong>MPLS</strong><br />
is independent <strong>of</strong> access technologies. (Leased Line, Frame<br />
Relay, ATM, Ethernet etc.)<br />
Integration <strong>of</strong> <strong>MPLS</strong> application components, including Layer 3<br />
VPNs, Layer 2 VPNs, Traffic Engineering, QoS, G<strong>MPLS</strong>, and IPV6<br />
enable the development <strong>of</strong> highly efficient, scalable, and secure<br />
<strong>network</strong>s that guarantee Service Level Agreements.<br />

this project<br />

IGX<br />
Trunks<br />
IGX traffic is decided <strong>to</strong> be carried port-<strong>to</strong>-port. That means all<br />
traffic from site IGX is carried <strong>to</strong> one port at central router. There<br />
is one-<strong>to</strong>-one port matching.<br />
IGX ATM trunks will be configured as Virtual Trunking using a<br />
single VPI <strong>to</strong> carry all connections.<br />
Clocking<br />
Voice applications need synchronization <strong>of</strong> the endpoints. To<br />
achieve this we synchronized all IGXs <strong>to</strong> Turkish telecom. The<br />
high-level design is <strong>to</strong> synchronize all the PABX switches <strong>to</strong> the<br />
Turkish telecom ISDN <strong>network</strong> and the IGX’s <strong>to</strong> the PABX<br />
switches.<br />

Traffic Engineering<br />
Most <strong>of</strong> the traffic flows <strong>to</strong> Data Center location. The YKB <strong>MPLS</strong><br />
Core Network is in mesh physical <strong>to</strong>pology and using all the<br />
physical links available <strong>to</strong> a POP is a must for YKB.<br />
Therefore, TE tunnels are used for each physical link <strong>to</strong> Data<br />
Center destination. This method hides the physical <strong>to</strong>pology from<br />
upper layer pro<strong>to</strong>cols and routing pro<strong>to</strong>cols see that there are as<br />
many tunnels <strong>to</strong> Data Center as the number <strong>of</strong> physical links<br />
Cisco IOS <strong>MPLS</strong> Au<strong>to</strong>route Announce installs the routes<br />
announced by the tail-end router and its downstream routers in<strong>to</strong><br />
the routing table (forwarding table) <strong>of</strong> the head-end router as<br />
directly reachable through the tunnel. This is the main method <strong>to</strong><br />
attract traffic over the link-protected tunnels within the YKB <strong>MPLS</strong><br />
Core Network.<br />

<strong>Migration</strong> Procedure<br />
Only one WAN link is moved from IGX <strong>to</strong> 7600<br />
All the functionalities are tested with this link. If<br />
something is wrong, it is easy at this stage <strong>to</strong> return<br />
back.<br />
If everything is okay, then all other WAN links are<br />
moved <strong>to</strong> 7600<br />
Tests are done in this state<br />
