EVOLUTION  AND  TRENDS     IN  MOBILE  NETWORKS  

The  Future  of  Mobility  –  2018  perspecBve   By  2018,  mobile  data  traffic   per  month  will  reach    

15.9  Ebs  

11-­‐fold  growth  from  2013   1000-­‐fold  from  2005  

By  2018,  over  

50%  of  Mobile   Traffic  will  come   from  4G  

By  2018,  there  will  be  more  

10  billion   50  billion  connected   than   total   mobile-­‐ready  devices   things  by  2020  -­‐  IoE  

By  2018,     2/3  of  the  world’s   mobile  data  traffic  will  be

Nodal  segment:  Operator  allocates  a  label  from  the  SR   registry  to  each  node.  For  example  Z  is  given  label  65   [any  packet  with  65  takes  the  shortest  path  to  Z]

Adjacency  segment:  Node  automaBcally  allocates  a  local  label  for   each  adjacency.  For  example  Label  9001  allocated  for  adjacency  C-­‐O   [9001  is  popped  and  packet  takes  this  link  to  O]   Combining  nodal  and  adjacency  segments  as  labels  stack:   The  state  is  no  longer  in  the  network,  it’s  in  the  packet!
