EtherChannel over WDM MUX on 7600

Dear All,



I am trying to increase bandwidth between my 7600s running as PE/P

routers with 1G line cards terminating dark fibre links.


I am exploring the following two options:


Option I

---------

- replace the 1G lines cards with 10G on the 7600s

- terminate the dark fibre links on the 10G line cards


Option II

----------

- terminate the dark fibre links on passive CWDM MUX

- EtherChannel multiple 1G interfaces over CWDM MUX


My main concern is about the efficiency of different load-balancing

algorithm offered in the EtherChannel technology in terms of maximum

achievable bandwidth.


Also, is there any issues of running Etherchannel over passive CWDM MUX ?



I will be really grateful for any comments or inputs on this.



Regards,



Zahid

hi zahid


I feel if you are conservative on spending lines you can you add on one more 1G port on both the sides and start doing load balancing but keeping the future in mind and also considering the traffic requirements you better think off going on for 10G line card.


What are the services being offered to your clients using this network ?


How many such boxes are required to be assessed and requires an upgrade ?


do you also have some kinda traffic projection done so that you can take up a concrete decision.
