Can I make the Angular.js instead of RIA for web application?

Recently I'm trying to change my development os platform.

[Current]
OS : windows Server 2008
WAS : IIS7
DB : MSSQL 2008
LANGUAGE : ASP.NET, C#
RIA : Embed IE - C# Form(smartclient) - view graph, grid, map(dashboard)
Socket : TCP/IP socket smartclient <-> unix server program

Currently, I'm trying to change window platform to linux(centos).
So, I read about full stack languages such as Angular.js, meteor.js, node.js-socket.io, etc...
But, I think that it some mismatch my app.
My webapp use some complex tcp communication.(use gzip, encrytion, sha2)
In addition, sometimes data is some big.(over 40000 bytes).
Also, I can't change unix server side tcp code cause that write other team.

I don't know exactly which one can support similar my currently webapp job.
If you know this case, please, advice me.
Thank you.
