Context Switching in SS7 Context
Nha^n noi' ve^` chu*~ context, kho^ng bie^'t ma^'y ba'c CS co'
nghe to*'i cu.m tu*` "context switching" kho^ng? Tu*` na`y ra^'t
tho^ng du.ng trong nga`nh to^i la`m (telecom/SS7), nhu*ng ne^'u
co' ai ba<'t di.ch ra tie^'ng Vie^.t thi` co' le~ to^i pha?i
dda^`u ha`ng tho^i. Cho to^i switch qua English context dde^?
gia?i thi'ch ro~ ho*n.
'Context' in this (particular and narrow) sense represents a "set of
data" associated with a particular SS7 message and is used by the SS7
network elements to properly identify and route the call. In order for
a network element to process multiple messages in real time, the
ability to store and restore (i.e. switch between) context information
for any message is required. The software implementation for this
capability is known in my professional world as "context switching"
and involves what is called a "context stack".
Allow me to now switch back to a Viet context. Cho ne^n chu*~ text
trong "context" trong "SS7 context" (recursive context??? :)) cha<?ng
di'nh da'ng gi` dde^'n chu*~ va<n ca?. Va^.y thi` pha?i ti'nh la`m sao
dda^y ma^'y ba'c?
Co`n chu*~ "recursion" cu~ng ra<'c ro^'i go*'m. Xin ma^'y ba'c giu'p
luo^n y' kie^'n cho.
