Resign from Ericsson

Today is my last day working at Ericsson. I feel so sad when will going out. But the show must go on. I should leaving Ericsson for my career aim. I will definitely miss our colleague whom work together during my services here

Dopod M700 Specification

I bought dopod M700 3 month ago. The situation has forced me buying a new one. My ipaq broken when i had been using it for GPRS ATP in customer. Well, my boss did not prepared any handset for this ATP activity. I have no other choice except using my own ppc to conduct this. But when it was down, i have to bought it with my own pocket. I chose this ppc because the price is not too expensive compared with the others. My option was only two, the other one was ipaq 6828. But i heard that HP would cutting off and discontinue the ipaq from their business, so i had not interested again.

From my experiences with M700, the cpu speed are slow. Some of my program doesn’t working well. I have to wait for a second while the program loaded. The camera quality just so.. so… its not enough for me (I was graphic designer, maybe my standart too high). I never tried to open the movie files (mov and avi format), but it seems this ppc works good with 3gp format (i tried with 10mb file size).

When I open the mp3 files, i feel the quality is very good. Then i tried to connected to the active speaker, and the result is awesome. The treble and bass is clear for my ears. Also, you can adjust bass and treble intensity from the control panel menu. So, i recommend this ppc if you want the gadges with multifunction and song lover. But if you have many programs, expecially programs which have large cpu consume, i do not recommend it .

LDP Tunelling Over RSVP

In this post i will try to explain LDP over RSVP concepts. For Some reason of the networks, sometimes we need to implement LDP and RSVP together. The main reason is existing and current networks doesn’t support RSVP.

All LDP neighbour are up.

LDP session is directly from router 1 to router 6.
